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.

EXPLANATION:
Okay, we are given that a program should be written which will make user to enter three cities namely Atlanta, Chicago and Los Angeles (which should be done in ascending alphabetical order).
So, we will be writting the code or program with a programming language known as JAVA(JUST ANOTHER VIRTUAL ACCELERATOR).
We will make use of java to write this program because Java can be used in Loading code, verifying codes and executing codes on a single or multiple servers.
The code or program can be seen in the attached file/document. Kindly check it.
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.

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 .Assume the following variable definition appears in a program:
double number = 12.3456;
Write a cout statement that uses the setprecision manipulator and the fixed manipulator to display the number variable rounded to 2 digits after the decimal point. (Assume that the program includes the necessary header file for the manipulators.)
Answer:
cout << setprecision(2)<< fixed << number;
Explanation:
The above statement returns 12.35 as output
Though, the statement can be split to multiple statements; but the question requires the use of a cout statement.
The statement starts by setting precision to 2 using setprecision(2)
This is immediately followed by the fixed manipulator;
The essence of the fixed manipulator is to ensure that the number returns 2 digits after the decimal point;
Using only setprecision(2) in the cout statement will on return the 2 digits (12) before the decimal point.
The fixed manipulator is then followed by the variable to be printed.
See code snippet below
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
// Initializing the double value
double number = 12.3456;
//Print result
cout << setprecision(2)<< fixed << number;
return 0;
}
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;

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.

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.

2-3 Calculating the Body Mass Index (BMI). (Programming Exercise 2.14) Body Mass Index is a measure of health based on your weight. It can be calculated by taking your weight in kilograms and dividing by the square of your height in meters. Write a program that prompts the user to enter a weight in pounds and height in inches and displays the BMI. Note: One pound is 0.45359237 kilograms and one inch is 0.0254 meters. Hint: Convert the pounds entered into kilograms also convert the height in inches into meters Example: If you entered in pounds your weight as 95.5 and your height as 50 inches then the calculated BMI is 26.8573 FYI: BMI < 18.5 is underweight BMI >
Answer:
weight = float(input("Enter your weight in pounds: "))
height = float(input("Enter your height in inches: "))
weight = weight * 0.45359237
height = height * 0.0254
bmi = weight / (height * height)
print("Your BMI is: %.4f" % bmi)
Explanation:
*The code is written in Python.
Ask the user to enter weight in pounds and height in inches
Convert the weight into kilograms and height into meters using given conversion rates

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.

//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) )

Program: ASCII art (Python 3)1) Output this tree. 2) Below the tree (with two blank lines), output this cat. (3 pts) /\ /\ o o = = --- Hint: A backslash \ in a string acts as an escape character, such as with a newline \n. So, to print an actual backslash, escape that backslash by prepending another backslash. Ex: The following prints a single backslash: System.out.println("\\");
The correct format for the output this tree is shown below:
(1) Output this tree

Answer:
Explanation:
We are given an Hint that:
A backslash \ in a string acts as an escape character, such as with a newline \n. So, to print an actual backslash, escape that backslash by prepending another backslash.
An Example : The following prints a single backslash: System.out.println("\\");
The main objective here is to use a Java code to interpret the above (1) Output this tree and (2) Below the tree.
So Using a Java code to interpret the Program: ASCII art ; we have:
public class AsciiArt {
public static void main(String[] args) {
// TODO Auto-generated method stub
//Draw Tree
System.out.println(" *");
System.out.println(" ***");
System.out.println(" *****");
System.out.println("*******");
System.out.println(" ***");
//output cat
System.out.println();
System.out.println("/\\\t/\\");
System.out.println(" o o");
System.out.println(" = =")
System.out.println(" ---");
}
OUTPUT:
SEE THE ATTACHED FILE BELOW.
The program is a sequential program, and does not require loops and conditional statements.

Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, Sketch the waveform produced by A when “$” is sent. Also mention the OSI layer that is responsible for this.
Answer:
Physical / Data link layer
Explanation:
If two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the data would be transmitted if the network is clear but if the network is not clear, the transmission would wait until the network is clear.
The Open Systems Interconnection model (OSI model) has seven layers each with its own function.
The physical layer is the first layer responsible for data transmission over a physical link. The data packets are converted to signals over a transmission media like ethernet cable.
The data link layer is the second layer in the OSI layer responsible for transmission of data packets between nodes in a network. It also provides a way of detecting errors and correcting this errors produced as a result of data transmission.
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.

Answer:It’s D
Explanation:
APEVX
The label of the next version of the document can probably be ProjectReport_v2.docx. The correct option is D.
What is a document?A document's purpose is to enable the transmission of information from its author to its readers.
It is the author's responsibility to design the document so that the information contained within it can be interpreted correctly and efficiently. To accomplish this, the author can employ a variety of stylistic tools.
Documentation can be of two main types namely, products and processes. Product documentation describes the product under development and provides instructions on how to use it.
A document file name is the name given to a document's electronic file copy.
The file name of the document does not have to be the same as the name of the document itself. In fact, you can use the shortest possible version of the name.
As the document here is second version of the previous one, so its name should be ProjectReport_v2.docx.
Thus, the correct option is D.
