Suppose you decide to use the number of times you see any of the area codes of the places Yanay has been to in 50 spam calls as your test statistic. Question 7. Write a function called simulate_visited_area_codes that generates exactly one simulated value of your test statistic under the null hypothesis. It should take no arguments and simulate 50 area codes under the assumption that the result of each area is sampled from the range 200-999 inclusive with equal probability. Your function should return the number of times you saw any of the area codes of the places Yanay has been to in those 50 spam calls. Hint: You may find the textbook section on the sample_proportions function to be useful. For model_proportions, under the null hypothesis, what's the chance of drawing one of the area codes Yanay has recently been to
Answer:
In Python:
import random
def simulate_visited_area_codes():
area_codes = []
for i in range(51):
num = random.randint(200,1000)
area_codes.append(num)
visited_codes = [289, 657, 786, 540]
count = 0
for i in range(51):
for j in range(len(visited_codes)):
if area_codes[i] == visited_codes[j]:
count+=1
return count
print("Visited Areas: "+str(simulate_visited_area_codes()))
Explanation:
So many incomplete details in your question, so I will fill in the gap (i.e. make assumptions)
The assumptions are:
The 50 area codes is stored in area_codes list; the codes are randomly generatedThe visited area codes is stored in visited_codes list, the list is initializes with [289, 657, 786, 540]The program and explanation is as follows: (comments are written in bold)
#This imports the random module
import random
#This defines the function
def simulate_visited_area_codes():
#Thie initializes area_codes to an empty list
area_codes = []
#This iterates from 1 to 50 and generate 50 random numbers to the area_codes list
for i in range(51):
num = random.randint(200,1000)
area_codes.append(num)
#This initializes the visited_code
visited_codes = [289, 657, 786, 540]
#This initializes count variable to 0
count = 0
#This iterates through the list and looks for matching code between the area_code and the visited_code lists
for i in range(51):
for j in range(len(visited_codes)):
if area_codes[i] == visited_codes[j]:
#The count variable is incremented by 1 for matching codes
count+=1
#This returns the count
return count
#The main begins here and prints the number of area code visited
print("Visited Areas: "+str(simulate_visited_area_codes()))

If the old code to a passcode was 1147, and someone changed it, what would the new code be?
(It’s no version of 1147, I already tried that. There are numbers at the bottom of the pictur, it just wouldn’t show.)
[I forgot my screen time passcode please someone help I literally can’t do anything on my phone.]
Answer:
There's no way for anyone but you to know the password. Consider this a lesson to be learned - keep track of your passwords (and do it securely). If you can't remember your password for this, the only alternative is to factory reset your device.
I don't know exactly if this passcode instance is tied to your Icloud account.. if it is, factory resetting will have been a waste of time if you sign back into your Icloud account. In this case, you would need to make a new Icloud account to use.
Define a function below, filter_out_strs, which takes a single argument of type list. Complete the function so that it returns a list that contains only the non-strings from the original list. It is acceptable to return an empty list if there are only strings in the original list. This question uses the filter pattern discussed in lecture.
Answer:
Explanation:
The following code is written in Python and is a simple function that removes all of the type String elements within the list that has been passed as an argument. Then finally, prints out the list and returns it to the user.
def filter_out_str(list):
for x in list:
if type(x) == type(" "):
list.remove(x)
print(list)
return list
Following are the python code to hold only string value into another list by using the given method:
Python code:def filter_only_strs(l):#defining the method filter_only_strs that takes list type variable l in parameter
r = []#defining an empty list r
for x in l:#defining a loop that counts value of list
if isinstance(x, str):#using if block that check list value is in string
r.append(x)#using an empty list that holds string value
return r#return list value
l=['d',12,33,"data"]#defining a list l
print(filter_only_strs(l))#calling the method filter_only_strs
Output:
Please find the attached file.
Program Explanation:
Defining the method "filter_out_strs", which takes one argument of list type that is "l".Inside the method, an empty list "r" is defined, and in the next line, a for loop is declared.Inside the for loop list "l" is used with a conditional statement that uses the "isinstance" method that checks string value in the list and adds its value in "r", and returns its value.Find out more about the list in python here:

Answer:
return 8 * x;
Explanation:
Required
What can replace the three lines of x = x + x
We have, on the first line:
[tex]x=>x +x[/tex]
[tex]x=>2x[/tex]
On the second line:
[tex]x=>x +x[/tex]
[tex]x=>2x[/tex]

Write code that sets the value of a variable named delicious to True if jellybeans is greater than 20, or licorice is greater than 30, or their sum is greater than 40. Otherwise, set it to False. Do NOT use an if statement in your solution. Assume jellybeans and licorice already have values.
Answer:
jellybeans = 10
licorice = 35
delicious = (jellybeans > 20) or (licorice > 30) or ((jellybeans + licorice) > 40)
print(delicious)
Explanation:
*The code is in Python.
Set the jellybeans and licorice to any values you like
In order to have the value of True or False without using the if statement, we need to set delicious as boolean variable. As you may know, boolean variables are the variables that have a value of either True or False
Check if jellybeans is greater than 20 or not → (jellybeans > 20)
Check if licorice is greater than 30 or not → (licorice > 30)
Check if their sum is greater than 40 or not → ((jellybeans + licorice) > 40)
All of the above expressions are boolean expressions. They return True if the statement is correct. Otherwise, they return False
Also, note that we combined all the expressions with or
For these values → jellybeans = 10, licorice = 35:
The first statement returns False
The second statement returns True
The third statement returns True
delicious = False or True or True → True
Note that if the expressions are combined with or, the result will be True if one of the expression is True.
The code that sets the value of a variable named delicious to True if jellybeans is greater than 20, or licorice is greater than 30, or their sum is greater than 40 is as follows:
jellybeans = 30
licorice = 35
delicious = (jellybeans > 20) or (licorice > 30) or (jellybeans + licorice > 40)
print(delicious)
Code explanationThe first line of code, we declared a variable called jellybeans and initialise it to 30.The second line of code, we declared a variable called licorice and initialise it to 35.Then the variable "delicious" is used to store the condition if jelly fish is greater than 20 or if licorice is greater than 30 or the sum of licorice and jellyfish is greater than 40 If any of the condition is true, the print statement will print out True else it will print False.learn more variable here : https://brainly.com/question/19661456?referrer=searchResults

Answer:
1. SELECT Order.customer_id, SUM(order_total) AS 'Total_order'
FROM Order JOIN Order_item
WHERE Order.customer_id = Order_item.customer_id
GROUP BY Order.customer_id
2. SELECT Order.customer_id, SUM(order_total) AS 'Total_order' , order_date
FROM Order JOIN Order_item
WHERE Order.customer_id = Order_item.customer_id
GROUP BY Order.customer_id, Order_item.order_date
ORDER BY Order_item.order_date
Explanation:
Both SQL queries return the total order from the joint order and order_item tables, but the second query returns the total order and their data grouped by customer and order date and also ordered by the order date.
. Suppose an instruction takes 1/2 microsecond to execute (on the average), and a page fault takes 250 microseconds of processor time to handle plus 10 milliseconds of disk time to read in the page. (a) How many pages a second can the disk transfer? (b) Suppose that 1/3 of the pages are dirty. It takes two page transfers to replace a dirty page. Compute the average number of instructions between page fault that would cause the system to saturate the disk with page traffic, that is, for the disk to be busy all the time doing page transfers.
Answer:
a. 100.
b. 31500.
Explanation:
So, we are given the following data which is going to help in solving this particular question.
The time required to execute (on the average) = 1/2 microsecond , a page fault takes of processor time to handle = 250 microseconds and the disk time to read in the page = 10 milliseconds.
Thus, the time taken by the processor to handle the page fault = 250 microseconds / 1000 = 0.25 milliseconds.
The execution time = [ 1/2 microseconds ]/ 1000 = 0.0005 milliseconds.
The number of Pages sent in a second by the disc = 1000/10 milliseconds = 100.
Assuming U = 1.
Hence, the disc transfer time = [2/3 × 1 } + [ 1/3 × 0.25 milliseconds + 15 ] × 2.
=0.667 + 15.083.
= 15.75 millisecond.
Average number of instruction = 15.75/0.0005 = 31500.
It should be noted that the number of pages in a second will be 100 pages.
From the information given, it was stated that the instruction takes 1/2 microsecond to execute and a page fault takes 250 microseconds of processor time to handle plus 10 milliseconds of disk time to read the page.
Therefore, the execution time will be:
= 0.5/1000
= 0.0005
Therefore, the number of pages will be:
= 1000/10
= 100
Also, the disc transfer time will be;
= (2/3 × 1) + (1/3 × 0.25 + 15) × 2
= 0.667 + 15.083
= 15.75
Therefore, the average number of instructions will be:
= 15.75/0.0005
= 31500

Create a Department object which contains a name (String), budget (double), and an ArrayList of Employee objects. Each Employee object contains a FirstName (String). LastName(String), and an Address object. Each Address object contains a Street (String), Apartment (int), City (String), and State as a char array of length 2. The Apartment parameter is optional but the other three are mandatory! Ensure no Address object can be created that does not have them. Finally, create a test program that allows users to Add, Delete, Print, and Search the Employees of a Department.

Pay special attention to the indigenous perspective, which will most likely be underrepresented in your research.
Answer:
Small pox, cacao, tobacco, tomatoes, potatoes, corn, peanuts, and pumpkins.
Explanation:
In the Columbian Exchange, transportation of plants, animals, diseases, technologies, and people from one continent to another held. Crops like cacao, tobacco, tomatoes, potatoes, corn, peanuts, and pumpkins were transported from the Americas to rest of the world. Due to this exchange, Native Americans were also infected with smallpox disease that killed about 90% of Native Americans because this is a new disease for them and they have no immunity against this disease. Due to this disease, the population of native Americans decreases and the population of English people increases due to more settlement.
Suppose you design a banking application. The class CheckingAccount already exists and implements interface Account. Another class that implements the Account interface is CreditAccount. When the user calls creditAccount.withdraw(amount) it actually makes a loan from the bank. Now you have to write the class OverdraftCheckingAccount, that also implements Account and that provides overdraft protection, meaning that if overdraftCheckingAccount.withdraw(amount) brings the balance below 0, it will actually withdraw the difference from a CreditAccount linked to the OverdraftCheckingAccount object. What design pattern is appropriate in this case for implementing the OverdraftCheckingAccount class
Answer:

Explanation:
The strategic design pattern is defined as the behavioral design pattern that enables the selecting of a algorithm for the runtime. Here the code receives a run-time instructions regarding the family of the algorithms to be used.
In the context, the strategic pattern is used for the application for implementing OverdraftCheckingAccount class. And the main aspect of this strategic pattern is the reusability of the code. It is behavioral pattern.
Suppose Alice and Bob have RSA public keys in a file on a server. They communicate regularly using authenticated, confidential messages. Eve wants to read the messages but is unable to crack the RSA private keys of Alice and Bob. However, she is able to break into the server and alter the file containing Alice's and Bob's public keys. a. How should Eve alter that file so that she can read confidential messages sent between Alice and Bob, and forge messages from either
Answer:
On the server, Eve could create and register her own version of Bob's and Alice's pairs of keys, then she can intercept the communication between Bob and Alice, decrypt the message and recalculate the hash, and also re-encrypting it all with her own version of Bob's and Alice's private and public keys.
Explanation:
Cryptography is the study of various methods to secure communication between two parties in the presence of a third known as adversaries.
Messages sent through communication mediums are encrypted to protect the confidentiality and integrity of their content. Using secure pins known as keys are used in some type of cryptography to encrypt and decrypt messages.
These keys are protected from adversaries and should be secured in servers.

Suppose that a computer has three types of floating point operations: add, multiply, and divide. By performing optimizations to the design, we can improve the floating point multiply performance by a factor of 10 (i.e., floating point multiply runs 10 times faster on this new machine). Similarly, we can improve the performance of floating point divide by a factor of 15 (i.e., floating point divide runs 15 times faster on this new machine). If an application consists of 50% floating point add instructions, 30% floating point multiply instructions, and 20% floating point divide instructions, what is the speedup achieved by the new machine for this application compared to the old machine
Answer:
1.84
Explanation:
Operation on old system
Add operation = 50% = 0.5
Multiply = 30% = 0.3
Divide = 20% = 0.2
T = total execution time
For add = 0.5T
For multiplication = 0.3T
For division = 0.2T
0.5T + 0.3T + 0.2T = T
For new computer
Add operation is unchanged = 0.5T
Multiply is 10 times faster = 0.3T/10 = 0.03T
Divide is 15 times faster = 0.2T/15= 0.0133T
Total time = 0.5T + 0.03T + 0.0133T
= 0.54333T
Speed up = Old time/ new time
= T/0.54333T

Explanation:
Objective
Make a function that solves the quadratic equation, outputting both values of X. You do not have to worry about imaginary numbers. That is, I will only use input that creates a real output (such as the example screenshots).
NOTE: A function that uses the C version of pass by reference is required to get full credit on this assignment. The C++ form of pass by reference will receive no credit.
Details
STEP 1
#include at the top of your file so that you can use the sqrt function. The sqrt function calculates the square root. For example:
int x = sqrt(9.0)
Will leave x with the value 3, which is the square root of 9.
STEP 2
Define a function THAT USES PASS BY REFERENCE to take in three double inputs and provides two double outputs. In the equations below I use a, b, and c as the double input names and x1 and x2 as the output names.
Inside this function solve the quadratic equation for both possible values of x:
X 1 = − b + b 2 − 4 a c 2 a
That is, X1 is equal to -b + sqrt(b * b - 4 * a * c) then divide all of that by 2 * a.
X 2 = − b − b 2 − 4 a c 2 a
That is, X2 is equal to -b - sqrt(b * b - 4 * a * c) then divide all of that by 2 * a.
Note the difference. One adds sqrt(b * b - 4 * a * c) and the other subtracts it.
This can be done in several lines of code if you want or you can attempt to perform the entire calculation in one line of code.
STEP 3
In the main function read in 3 inputs from the user. Pass these inputs to the quadratic equation function along with the pass by reference variables for the output. Print the results to the screen.
Advice
Your quadratic equation function does NOT need to account for imaginary numbers. Stick with the example inputs to test your code.
If you get NAN that means your equation has an imaginary solution. Do not worry about it. Try different inputs.
The calculation itself is a minor portion of this grade. The majority of the grade comes from implementing pass by reference so make sure you have that part correct.
b2 is simple enough that you do not need to call the pow() function to calculate the power. Instead multiply b * b.
You may want to calculate the numerator into one variable and the denominator into another. You don't have to solve the entire equation on one line (though that is possible).
Since you are using pass by reference you can make the QuadraticEquation function into a void function. It does not need to return anything since it is returning calculations via pointers.
Use scanf on one variable at a time. Don't forget to use double data types and %lf with scanf.
Answer:
In C
#include <stdio.h>
#include<math.h>
void myfunc(double *a, double *b, double *c) {
double x1, x2;
x1 = (-(*b) + sqrt((*b)*(*b)- 4*(*a)*(*c)))/(2*(*a));
x2 = (-(*b) - sqrt((*b)*(*b) - 4*(*a)*(*c)))/(2*(*a));
printf("x1 = %f\n",x1);
printf("x2 = %f\n",x2);}
int main () {
double a,b,c;
printf("a: "); scanf("%lf", &a);
printf("b: "); scanf("%lf", &b);
printf("c: "); scanf("%lf", &c);
myfunc(&a, &b, &c);
return 0;}
Explanation:
#include <stdio.h>
#include<math.h> --- This represents step 1
Step 2 begins here
This gets the values of a, b and c from main by reference
void myfunc(double *a, double *b, double *c) {
This declares x1 and x2
double x1, x2;
Calculate x1
x1 = (-(*b) + sqrt((*b)*(*b)- 4*(*a)*(*c)))/(2*(*a));
Calculate x2
x2 = (-(*b) - sqrt((*b)*(*b) - 4*(*a)*(*c)))/(2*(*a));
Print x1
printf("x1 = %f\n",x1);
Print x2
printf("x2 = %f\n",x2);}
Step 3 begins here
int main () {
Declare a, b and c as double
double a,b,c;
Get input for a, b and c
printf("a: "); scanf("%lf", &a);
printf("b: "); scanf("%lf", &b);
printf("c: "); scanf("%lf", &c);
Call the function to calculate and print x1 and x2
myfunc(&a, &b, &c);
return 0;}
1. P=O START: PRINT PP = P + 5 IFP
<=20 THEN GOTO START: * what is output
Answer:
0
5
10
15
20
Explanation:
P=O should be P=0, but even with this error this is the output.
When P reaches 20 it will execute the loop once more, so 20 gets printed, before getting increased to 25, which will not be printed because then the loop ends.
what is computer? different between RAM and ROM?
Answer:
RAM, which stand for RANDOM ACESS MEMORY and ROM whitch stand for READ ONLY MEMORY, are both present in your computer. RAM volatile memory that temporary store the file you are working on. ROM is a non volatile memory that permanently stores instruction for your COMPUTER.
Recall that within the LinkedCollection the numElements variable holds the number of elements currently in the collection, and the head variable of type LLNode holds a reference to the beginning of the underlying linked list. The LLNode class provides setters and getters for its info and link attributes. Complete the implementation of the add method:
public boolean remove (T target)
// Removes an element e from this collection such that e.equals (target)
// and returns true; if no such element exists, returns false.
find(target);
if (found)
// complete the method body
return found;
