Explanation:
A simple gullible algorithm is present. Let h mark the house to the left. Then we put a base station about 4 kilometers to the right. Now delete and repeat all the houses protected by this base station. In this algorithm, they can simply be seen to position baselines at b1, . . , bk as well as other algorithms (which may be an optimum algorithm) at [tex]b'_{1}, \ . . . . . . ,b'_{k'}[/tex] and so on. (from left to right) [tex]b_1 \geq b'_{1},\ \ b_2 \geq b'_{2}[/tex] That's why [tex]k \leq k'[/tex].
The Payroll Department keeps a list of employee information for each pay period in a text file. The format of each line of the file is the following: Write a program that inputs a filename from the user and prints to the terminal a report of the wages paid to the employees for the given period. The report should be in tabular forma
Answer:
In Python:
fname = input("Filename: ")
a_file = open(fname)
lines = a_file.readlines()
print("Name\t\tHours\t\tTotal Pay")
for line in lines:
eachline = line.rstrip(" ")
for cont in eachline:
print(cont,end="\t")
print()
Explanation:
This prompts the user for file name
fname = input("Filename: ")
This opens the file
a_file = open(fname)
This reads the lines of the file
lines = a_file.readlines()
This prints the header of the report
print("Name\t\tHours\t\tTotal Pay")
This iterates through the content of each line
for line in lines:
This splits each line into tokens
eachline = line.rstrip(" ")
This iterates through the token and print the content of the file
for cont in eachline:
print(cont,end="\t")
print()
# 1) Complete the function to return the result of the conversion
def convert_distance(miles):
km = miles * 1.6 # approximately 1.6 km in 1 mile
my_trip_miles = 55
# 2) Convert my_trip_miles to kilometers by calling the function above
my_trip_km = ___
# 3) Fill in the blank to print the result of the conversion
print("The distance in kilometers is " + ___)
# 4) Calculate the round-trip in kilometers by doubling the result,
# and fill in the blank to print the result
print("The round-trip in kilometers is " + ___)
Answer:
See explanation
Explanation:
Replace the ____ with the expressions in bold and italics
1) return km
return km returns the result of the computation
2) = convert_distance(my_trip_miles)
convert_distance(my_trip_miles) calls the function and passes my_trip_miles to the function
3) + str(my_trip_km)
The above statement prints the returned value
4) +str(my_trip_km * 2)
The above statement prints the returned value multiplied by 2

literay to the society
Explanation:
Information literacy is important for today's learners, it promotes problem solving approaches and thinking skills – asking questions and seeking answers, finding information, forming opinions, evaluateing sources, and making decisions fostering successful learners, effective contributors, and confident individuals.A drunkard in a grid of streets randomly picks one of four directions and stumbles to the next intersection, then again randomly picks one of four directions, and so on. You might think that on average the drunkard doesn’t move very far because the choices cancel each other out, but that is actually not the case. Represent locations as integer pairs (x, y). Implement the drunkard’s walk over 100 intersections, starting at (0, 0), and print the ending location.

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.
Answer:
Explanation:
The following code is very long and is split into the 4 classes that were requested/mentioned in the question: Department, Employee, Address, and Test. Each one is its own object with its own constructor. Getters and Setters were not created since they were not requested and the constructor handles all of the variable creation. Address makes apartment variable optional by overloading the constructor with a new one if no argument is passed upon creation.

If name is a String instance variable, average is a double instance variable, and numOfStudents is a static int variable, why won’t the following code from a class compile?public Student(String s) {name = s;average = getAverage(name);numOfStudents++;}public double getAverage(String x) {numOfStudents++;double ave = StudentDB.getAverage(x);return ave;}public static void setAverage(double g) {average = g;}a.The setAverage() method can’t access the average instance variable.b.The getAverage() method can’t increment the numOfStudents variable.c.The constructor can’t increment the numOfStudents variable.d.The getAverage() method can’t call a static method in the StudentDB class.
Answer:
a.
Explanation:
Based solely on the snippet of code provided on the question the main reason why the code won't compile (from the options provided) is that the setAverage() method can’t access the average instance variable. Since the average variable is an instance variable it means that it only exists inside the one of the functions and not to the entire class. Meaning that in this scenario it can only be accessed by the Student function and once that function finishes it no longer exists. Also, it is not one of the options but if these variables are instance variables as mentioned their type needs to be defined inside the function.

You are working for a company that is responsible for determining the winner of a prestigious international event, Men’s Synchronized Swimming. Scoring is done by eleven (11) international judges. They each submit a score in the range from 0 to 100. The highest and lowest scores are not counted. The remaining nine (9) scores are averaged and the median value is also determined. The participating team with the highest average score wins. In case of a tie, the highest median score, among the teams that are tied for first place, determines the winner.
Scoring data is be provided in the form of a text file. The scoring data for each team consists of two lines; the first line contains the team name; the second line contains the eleven (11) scores. You will not know ahead of time how many teams will participant. Your program will:
Prompt the user for the name and location of the scoring data file.
Process the sets of records in the file.
Read and store the team name in a string variable.
Read and store the scores in an array.
Display the team name followed by the complete set of scores on the next line.
Calculate and display to two decimal places the average of the nine qualifying scores, dropping the lowest and highest scores.
Determine and display the median value among the qualifying scores.
Display the count of the number of participating teams.
Display the winning team name and their average score. Indicate if they won by breaking a tie with a higher median score value.
A sample data file has been provided to allow you to test your program before submitting your work. Records in the sample data file look like this:
Sea Turtles
11 34 76 58 32 98 43.5 87 43 23 22
Tiger Sharks
85 55 10 99 35 5 65 75 8 95 22
The Angry Piranhas
30 10 80 0 100 40 60 50 20 90 70
The average score for the Sea Turtles was 46.5. The Angry Piranhas and the Tiger Sharks both had an average score of 50.0. The tiger sharks had a median value of 55.0, making them the winners of the competition.
You will define and use at least one function in your solution. As a suggestion, you should consider calling a function that sorts the array of judge’s score values into ascending order (lowest to highest). The advantage of doing this is that after being sorted, the lowest value is the first entry in your array and the highest value is the last entry in your array.
The average or arithmetic mean is a measure of central tendency. It is a single value that is intended to represent the collection of values. For this problem, you will only use nine of the values to determine the average. You will not include the highest score and the lowest score.
The median is another measure of central tendency. The median is often referred to as the middle value. In a set of values, half the values are less than the median and the other half are greater than the median. In a sorted array of five elements, the median is the third element. There are two values that are less then it and there are two values that are greater than it. In a sorted array of six values, the median is the simple average of the third and fourth values. In some cases, the median is a better representative value than the average.

Create an array of doubles to contain 5 values Prompt the user to enter 5 values that will be stored in the array. These values represent hours worked. Each element represents one day of work. Create 3 c-strings: full[40], first[20], last[20] Create a function parse_name(char full[], char first[], char last[]). This function will take a full name such as "Noah Zark" and separate "Noah" into the first c-string, and "Zark" into the last c-string.

Explanation:
Answer- C
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;}
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()))
Simulate one or more responses from the distribution corresponding to a fitted model object.
