Description
There is a cricket that lives by our timeshare in Myrtle Beach, South Carolina. Most every night I hear it patiently chirping away. Some nights it chirps faster than others, and it seems like the warmer it is, the faster it chirps. There are many crickets, and each of them seems to behave the same. On several different nights, armed with a stopwatch and a thermometer, I recorded the frequency of the chirps and compared it to that night's air temperature.
Experimental Results
The chirping follows a simple linear formula: take the number of chirps, add 40 and divide that sum by four to get the temperature in degrees Fahrenheit.
Assignment
Create a simulation to model the crickets chirping at various randomly generated frequencies, create an Environmentclass that knows and can return the current temperature. Create a Cricket class that chirps, or for simplicity, returns how many chirps per minute the cricket would make at that temperature. Repeat the simulation for at least three trials.
Extension: There is a cricket variety in some parts of South Carolina that is a little slower than most normal Carolina crickets. Add a ClemsonCricket class that extends Cricket but chirps slower by 20%.
Bonus: Implement polymorphism in the driver class.
Rubrics
Cricket class should include the following items:
A variable that stores the frequency of chirps.
A default constructor that initializes the frequency to a random value
An overloaded constructor that initializes the frequency to a value of your choice that gets passed on as a parameter.
A method for changing the frequency to a random value.
A getter method that returns the frequency.
clemsonCricket class should include the following items:
A default constructor that initializes the frequency to a random value that is 20% lower than what the parent class constructor would initialize it to.
A overloaded constructor that calls to the parent constructor.
A polymorphic method that changes the frequency value to a value that is 20% lower than what the parent method would change it to.
Environment class should include the following items:
A variable that stores the temperature.
A default constructor that initializes the temperature to a value of your choosing.
An overloaded constructor that initializes the temperature based on the formula in the assignment.
A method that takes in a frequency as a parameter and calculates the temperature based on the formula in the assignment.
testCrickets program should do the following items:
Creates an Environment object in the test program or in the Cricket or clemsonCricket classes and displays temperature Creates a cricket object and displays temperature before and after changing frequency
Creates a Clemson cricket object and displays temperature before and after changing frequency
Creates a polymorphic Clemson cricket object and displays temperature before and after changing frequency.

What color model should Joe use if he will be using an offset printing press?
Answer:
The color model used for an offset printing press should involve cyan, magenta, yellow and black. The combination of this creates a black color.
Offset printing doesn’t involve the direct contact of the ink with the paper. The ink usually comes in contact first with a rubber cylinder after which the cylinder makes the necessary imprints on the paper.

Richard Palm is the accounting clerk of Olive Limited. He uses the source documents such as purchase orders, sales invoices and suppliers’ invoices to prepare journal vouchers for general ledger entries. Each day he posts the journal vouchers to the general ledger and the related subsidiary ledgers. At the end of each month, he reconciles the subsidiary accounts to their control accounts in the general ledger to ensure they balance.
Discuss the internal control weaknesses and risks associated with the above process. (maximum 300 words)
Answer:
Lack of segregation of duties
Explanation:
Internal Controls are set of rules and guidelines that are followed to ensure effectiveness of business operations. The main risk in the business is weak internal controls. There are some organizations with strong internal controls but implementation of such controls is a challenge for organizations. There are human errors, IT security risks, fraud and compliance risk.
The risks associated with Olive limited is that there is no segregation of duties, Richard Palm is preparing journal vouchers, posts the journal vouchers and reconciles the balance himself. If he makes an error in recording a transaction there is no one who reviews his work and can identify an error. Also if Richard is involved in a fraud and collaborates with purchase department or sales department staff, he can pass a transaction without any supervision.
Find the error in the following pseudocode.
Module main()
Declare Real mileage
Call getMileage()
Display "You've driven a total of ", mileage, " miles."
End Module
Module getMileage()
Display "Enter your vehicle’s mileage."
Input mileage
End Module
Answer:
Following are the error in the given program are explain in the explanation part .
Explanation:
The main() function call the function getMileage() function after that the control moves to the getMileage() definition of function. In this firstly declared the "mileage" variable after that it taking the input and module is finished we see that the "mileage" variable is local variable i,e it is declared inside the " Module getMileage() " and we prints in the main module that are not possible to correct these we used two technique.
Technique 1: Declared the mileage variable as the global variable that is accessible anywhere in the program.
Technique 2: We print the value of "mileage" inside the Module getMileage() in the program .
After pushing the power switch of the PC to the ʺonʺ position, Bob, the PC repair person, realizes that the power-on lights found on the monitor and computer case do not light up and nothing displays on the screen. The first thing that Bob does is check the power plugs found on the back of the computer case and monitor. Bobʹs actions best illustrate the use ________ in solving a problem.
1. Professional and technical training
2. Logic3. Communication
4 .Beginnerʹs luck
Answer:
2. Logic
Explanation:
We all know that for the PC to come on, there must be a power input, this means that if the PC does not power on, then there is probably no power input into the PC. It is only logical for Bob to check if the PC is properly connected first when the power-on lights did not come on. People with no technical training should be able to apply this simple logic too.

Canadian Tire is one of Canada’s largest companies. They operate four large distribution centers service over 470 tire retail outlets. They recently installed a Yard Management System (YMS), which they have integrated with their Warehouse Management Systems (WMS) and Transport Management System (TMS) systems. Their expectation was improved performance in over-the-road transportation equipment utilization, driver productivity, and warehouse dock/door utilization. As a relatively new logistics employee, you have been asked to develop an evaluation system to measure operational productivity improvement. While management does not want a financial impact evaluation, they are interested in developing benchmarks to measure initial and sustainable productivity improvement. You have the job-how would you proceed?
Answer: Provided in the explanation section
Explanation:
A YMS acts an interface between a WMS and TMS.The evaluation system with the key performance indicators are mentioned in the table below.
NOTE: The analysis follows in this order given below
MetricDescriptionCommentsMetric 1
Trailer utilization
Description :This captures the status of the trailer whether it is in the yard or is in transit
Comments : Helps in measuring the trailer productivity on a daily ,weekly or monthly basis
Metric 2
Driver utilization
Description : This captures the status of the driver whether the driver is in the yard or is in transit
Comments : Helps in measuring the driver productivity on a periodic basis
Metric 3
Trailer sequence
Description : This captures the order of movement of trailers in the yard on a given day, week or month
Comments : Helps in measuring the order fulfilment efficiency i.e. whether the priority orders have been serviced first or not
Metric 4
Total time in yard
Description : This captures the time spent by the trailer in the yard from the time it enters and leaves the yard
Comments : This helps in measuring the time taken to fulfill a particular request
⇒ Capturing these metrics need inputs from both WMS and TMS, and also the trailers need to have RFID tags attached to them.Then compare these performance metrics with the ones prior to the deployment of YMS to identify the percent gains in the overall operational productivity.

(TCO C) When a remote user attempts to dial in to the network, the network access server (NAS) queries the TACACS+ server. If the message sent to the server is REJECT, this means _____.
Answer:
The correct answer to the following question will be "The user is prompted to retry".
Explanation:
NAS seems to be a category of server system a broader open internet as well as web through in-house and perhaps remotely associated user groups.
It handles as well as provides linked consumers the opportunity to provide a collection of network-enabled applications collectively, thereby integrated into a single base station but rather portal to infrastructure.Unless the text or response sent to the server seems to be REJECT, this implies that the authentication process continued to fail and therefore should be retried.What are two key elements of describing the environment? a.

Explanation:
In this scenario, two friends are eating dinner at a restaurant. The bill comes in the amount of 47.28 dollars. The friends decide to split the bill evenly between them, after adding 15% tip for the service. Calculate the tip, the total amount to pay, and each friend's share, then output a message saying "Each person needs to pay: " followed by the resulting number.
Answer:
The java program for the given scenario is as follows.
import java.util.*;
import java.lang.*;
public class Main
{
//variables for bill and tip declared and initialized
static double bill=47.28, tip=0.15;
//variables for total bill and share declared
static double total, share1;
public static void main(String[] args) {
double total_tip= (bill*tip);
//total bill computed
total = bill + total_tip;
//share of each friend computed
share1 = total/2;
System.out.printf("Each person needs to pay: $%.2f", share1);
}
}
Explanation:
1. The variables to hold the bill and tip percent are declared as double and initialized with the given values.
static double bill=47.28, tip=0.15;
2. The variables to hold the values of total bill amount and total tip are declared as double.
3. All the variables are declared outside main() and at class level, hence declared as static.
4. Inside main(), the values of total tip, total bill and share of each person are computed as shown.
double total_tip= (bill*tip);
total = bill + total_tip;
share1 = total/2;
5. The share of each person is displayed to the user. The value is displayed with only two decimal places which is assured by %.2f format modifier. The number of decimal places required can be changed by changing the number, i.e. 2. This format is used with printf() and not with println() method.
System.out.printf("Each person needs to pay: $%.2f", share1);
6. The program is not designed to take any user input.
7. The program can be tested for any value of bill and tip percent.
8. The whole code is put inside a class since java is a purely object-oriented language.
9. Only variables can be declared outside method, the logic is put inside a method in a purely object-oriented language.
10. As shown, the logic is put inside the main() method and only variables are declared outside the method.
11. Due to simplicity, the program consists of only one class.
12. The output is attached.
Answer:
bill = 47.28
tip = bill *.15
total = bill + tip
share = total
print( "Each person needs to pay: "+str(share) )

The OSI is reference/conceptual model and accordingly multiple practical models (such as TCP/IP, AppleTALK, etc) exits. Which fundamental functionalities necessarily needs to considered while implementing any network model?
Answer:
The fundamental functionalities necessarily needs to considered while implementing any network model are (1) Scalability, (2)The quality of service (3) Fault tolerance (4) Security.
Explanation:
Solution:
Network must help a wide area of applications and administrations, just just as work over various sorts of links and devices that make up the physical infrastructure. The term network refers to the innovations that help the infrastructure and the customized administrations and rules, or protocols, that move messages over the network.
The following are some fundamental functionalities necessarily needs to considered while implementing any network model which is stated below:
(1) Scalability :
A huge number of users and service providers connect with the Internet every week. All together for the Internet to help this fast measure of development, it must be scalable.
A scalable network can extend rapidly to help new clients and applications without influencing the performance of the administration being conveyed to existing clients.
(2)Quality of Service :
Networks must provide predictable, quantifiable, and, now and again, ensured administrations.
Networks also need mechanisms to carry on congested network traffic. Network bandwidth is the estimate of the data-transfer size of the network. As such, what amount of data can be transmitted inside a particular measure of time? Network data transfer capacity is estimated in the quantity of bits that can be transmitted in a solitary second, or bits every second (bps).
(3) Fault Tolerance :
The Internet is consistently accessible to the a huge number of users who depend on it. This requires a network design that is worked to be fault tolerant.
A fault-tolerant network is one that constrains the impact of a failure, with the goal that the least number of devices are influenced by it. It is likewise worked in a manner that empowers fast recuperation when such a failure happens.
Faults-tolerant networks rely upon various ways between the source and destination of a message. On the off chance that one way comes up short, the messages can be immediately sent over an alternate connection.
(4) Security:
The Internet has advanced from a firmly controlled inter network of instructive and government associations to a generally open methods for transmission of business and individual interchanges.
Subsequently, the security necessities of the network have changed. The network infrastructure, the system administrations, and the information contained on arrange appended gadgets are vital individual and business resources. Bargaining the respectability of these benefits could have genuine outcomes.

Given parameters b and h which stand for the base and the height of an isosceles triangle (i.e., a triangle that has two equal sides), write a C program that calculates: The area of the triangle; The perimeter of the triangle; And The volume of the cone formed by spinning the triangle around the line h The program must prompt the user to enter b and h (both of type double) The program must define and use the following three functions: Calc Area (base, height) //calculates and returns the area of the triangle Calc Perimeter (base, height) //calculates and returns the perimeter Calc Volume(base, height) //calculates and returns the volume
Answer:
The area of the triangle is calculated as thus:
[tex]Area = 0.5 * b * h[/tex]
To calculate the perimeter of the triangle, the measurement of the slant height has to be derived;
Let s represent the slant height;
Dividing the triangle into 2 gives a right angled triangle;
The slant height, s is calculated using Pythagoras theorem as thus
[tex]s = \sqrt{b^2 + h^2}[/tex]
The perimeter of the triangle is then calculated as thus;
[tex]Perimeter = s + s + b[/tex]
[tex]Perimeter = \sqrt{b^2 + h^2} + \sqrt{b^2 + h^2} +b[/tex]
[tex]Perimeter = 2\sqrt{b^2 + h^2} + b[/tex]
For the volume of the cone,
when the triangle is spin, the base of the triangle forms the diameter of the cone;
[tex]Volume = \frac{1}{3} \pi * r^2 * h[/tex]
Where [tex]r = \frac{1}{2} * diameter[/tex]
So, [tex]r = \frac{1}{2}b[/tex]
So, [tex]Volume = \frac{1}{3} \pi * (\frac{b}{2})^2 * h[/tex]
Base on the above illustrations, the program is as follows;
#include<iostream>
#include<cmath>
using namespace std;
void CalcArea(double b, double h)
{
//Calculate Area
double Area = 0.5 * b * h;
//Print Area
cout<<"Area = "<<Area<<endl;
}
void CalcPerimeter(double b, double h)
{
//Calculate Perimeter
double Perimeter = 2 * sqrt(pow(h,2)+pow((0.5 * b),2)) + b;
//Print Perimeter
cout<<"Perimeter = "<<Perimeter<<endl;
}
void CalcVolume(double b, double h)
{
//Calculate Volume
double Volume = (1.0/3.0) * (22.0/7.0) * pow((0.5 * b),2) * h;
//Print Volume
cout<<"Volume = "<<Volume<<endl;
}
int main()
{
double b, h;
//Prompt User for input
cout<<"Base: ";
cin>>b;
cout<<"Height: ";
cin>>h;
//Call CalcVolume function
CalcVolume(b,h);
//Call CalcArea function
CalcArea(b,h);
//Call CalcPerimeter function
CalcPerimeter(b,h);
return 0;
}
The goal for me is that I need to identify the objects needed for the UNO card game and the actions that those objects perform, rather than how the objects are suppose to actually be represented. Write a document that includes an ADT (abstract data type) for each object needed in my program. This is a partial ADT for the UnoCard class.
//get the color of the car
+getColor(): String
//set the color of the card
+setColor(color : String):void
//get the value of the card
+getValue(): int
//set the value of the card
+getValue(val : int): void
//return true if card has same value or
//same color as the card
//return false otherwise
+isMatch(card: UnoCard): boolean
The standard UNO card must be able to report both its color and value, and, when given another card, tell whether or not it is a "match.
Answer:
Explanation:
//Java program
class UnoCard{
private String color;
private int value;
public UnoCard(String color , int val) {
this.color = color;
value = val;
}
public String getColor() {
return color;
}
//set the color of the card
public void setColor(String color ) {
this.color = color;
}
//get the value of the card
public int getValue() {
return value;
}
//set the value of the card
public void setValue(int val) {
value = val;
}
//return true if card has same value or
//same color as the card
//return false otherwise
public boolean isMatch(UnoCard card) {
return (this.value==card.value)||(this.color==card.color);
}
}
public class Card {
public static void main(String args[]) {
UnoCard card1 = new UnoCard("Red",10);
UnoCard card2 = new UnoCard("Green",10);
UnoCard card3 = new UnoCard("Blue",15);
if(card1.isMatch(card2))System.out.println("Match");
else System.out.println("No Match");
if(card2.isMatch(card3))System.out.println("Match");
else System.out.println("No Match");
}

The skip_elements function returns a list containing every other element from an input list, starting with the first element. Complete this function to do that, using the for loop to iterate through the input list.
Answer:
Following are code that we fill in the given in the given question
if i %2==0:# check the condition
new_list.append(elements[i])# append the list
return new_list # return the new_list
Explanation:
Missing Information :
def skip_elements(elements):# function
new_list=[]# Declared the new list
i=0 #variable declaration
for i in range(len(elements)): #iterating over the loop
if ---------# filtering out even places elements in the list
--------------# appending the list
return -------- # returning the new_list
print(skip_elements(['a','b','c','d','e','f','g'])) #display
Following are the description of the code:
In this we declared a function skip_elements .In this function we pass the parameter into them .After that we declared the new_list array.Declared the variable "i" that are initialized with the 0 value .Iterating over the for loop and this loop we check the condition in the if condition.The if condition executed when the index is even .The statement inside the if condition we will appending the list and returning the list item .Finally we print the even number of index list .Social engineering attacks can be carried out:______.
a. only through physical proximity, such as shoulder surfing.
b. remotely by highly sophisticated means and subject matter experts (SMEs).
c. only for fun, they don't give any useful information to the attacker, except may be by entering a building without an ID or something such.
d. via password cracking software, such as Rainbow trees.
Write a method that computes the sum of the digits in an integer. Use the following method header: public static int sumDigits(long n) For example, sumDigits(234) returns 9 the result of 2 3 4. (Hint: Use the % operator to extract digits, and the / operator to remove the extracted digit. For instance, to extract 4 from 234, use 234 % 10, which is 4. To remove 4 from 234, use 234 / 10, which is 23. Use a loop to repeatedly extract and remove the digit until all the digits are extracted.
Answer:
The java program for the given scenario is shown below.
import java.util.*;
import java.lang.*;
public class Test
{
//variables to hold the number, digits and sum of the digits
//variable to hold number is assigned any random value
static long num=123;
static int sum=0;
static int digit;
static int s;
//method to add digits of a number
public static int sumDigits(long n)
{ do
{
digit=(int) (n%10);
sum=sum+digit;
n=n/10;
}while(n>0);
return sum;
}
public static void main(String[] args) {
s = sumDigits(num);
System.out.println("The sum of the digits of "+num+ " is "+s); }
}
OUTPUT
The sum of the digits of 123 is 6
Explanation:
1. The variables to hold the number is declared as long and initialized.
2. The variables to store the digits of the number and the sum of the digits are declared as integer. The variable, sum, is initialized to 0.
3. The method, sumDigits(), is defined which takes a long parameter and returns an integer value. The method takes the number as a parameter and returns the sum of its digits.
4. Inside method, sumDigits(), inside the do-while loop, the sum of the digits of the parameter is computed.
5. Inside main(), the method, sumDigits(), is called. The integer value returned by this method is stored in another integer variable, s.
6. The sum of the digits is then displayed to the console.
7. All the variables are declared outside main() and at the class level and hence declared static. The method, sumDigits(), is also declared static since it is to be called inside main().
8. In java, the whole code is written inside a class since java is a purely object-oriented language.
9. In this program, object of the class is not created since only a single class is involved having main() method.
10. The program can be tested for any value of the variable, num.
11. The file is saved as Test.java, where Test is the name of the class having main() method.
