Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non-negative integers as input, and outputs the max and average. A negative integer ends the input and is not included in the statistics. Assume the input contains at least one non-negative integer. Output the average with two digits after the decimal point followed by a newline, which can be achieved as follows: System.out.printf("%.2f\n", average); Ex: When the input is: 15 20 0 3 -1 the output is: 20 9.50 379284.2472260.qx3zay7 LAB LAB: Varied amount of input data АСTIVITY LabProgram.java Load default template.. import java.util.Scanner; public class LabProgram { public static void main (String[] args) { /* Type your code here. */

Statistics are often calculated with varying amounts of input data. Write a program that prompts for and takes any number of non-negative integers as input, and outputs the average and max. A negative integer ends the input and is not included in the statistics. Example program run (the user types only the numbers, in this case 15 20 0 5 -1): Enter numbers separated by spaces, with a negative number to quit: 15 20 0 5 -1 Average = 10 Max = 20 #include <iostream>using namespace std;/* program that prompts for and takes any number of non-negative integers as input, and outputs the average and max.

Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…
f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…
write a program in python Write a program that will allow a student to enter their name and then ask them to solve 10 mathematical equations. The program should display two random numbers that are to be added, such as: 247 + 129 The program should allow the student to enter the answer. The program should then display whether their answer was right or wrong, and accumulate the right values. After the 10 questions are asked, calculate the average that was correct. Then display the student name, the number correct, and the average correct in both decimal and percentage format. In addition to any system functions you may use, you might consider the following functions: A function that allows the student to enter their name. A function that gets two random numbers, anywhere from 1 to 500. A function that displays the equation and asks the user to enter their answer. A function that checks to see if the answer is correct and accumulates the number correct. A function that calculates the…
Write a program that helps a company manage salaries of its employees. Your program should ask for the number of hours worked and the hourly rate of an employee than, display the salary. This program should allow the user to enter the information of many employees until enters -1. Sample Run: Enter the number of hours worked (-1 to end): 32 Enter hourly rate of the worker: 100 Balary is 03200 Enter the number of hours Worked (-1 to end) : 40 Enter hourly rate of the worker: 5 Balary is 3200 Enter the number of hours worked (-1 to end): 42 Enter hourly rate of the worker: 10 Salary is 0420 Enter the number of hours worked (-1 to end) : -1
Given the sample code above in generating a random number. Create a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 13. The computer's choice is displayed. 4. A winner is selected according to the following rules: a. If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) b. If one player chooses scissors and the other player chooses paper, then scissor wins. (Scissors cuts paper.) c. If one player chooses paper and the other player…
Questions 1. Write a program which asks the user to enter a six-digit number and print a new number by subtracting 1 to each of its digits. For example, if the number entered is 393201, the output should be displayed as 282190. Information on the console should be displayed similar to the Sample Run shown below. Sample Run: Enter a 6 digit number: 393201 Modified number is: 28219d
Write a program that helps a company manage salaries of its employees. Your program should ask for the number of hours worked and the hourly rate of an employee than, display the salary. This program still asks the user to enter the information of many employees until enters a zero value. Sample Run: Enter the number of hours worked (negative nbr to end): 32 Enter hourly rate of the worker: 100 Your salary is $3200 Enter the number of hours worked (negative nbr to end): 40 Enter hourly rate of the worker: 5 Your salary is $200 Enter the number of hours worked (negative nbr to end): 42 Enter hourly rate of the worker: 10 Your salary is 5420 Enter the number of hours worked (negative nbr to end): 0
Get three exam grades from the user and compute the average of the grades. Output the average of the three exams. Together with the average, also include a Remark: Passed in the output if the average is greater than or equal to 70, otherwise output Remark: Failed. NOTE: Your source code must display any of the given sample output below. It means your source code should be flexible enough to meet any of the given sample output. Your source code output must be identical to any of the given sample output. It means you have to strictly follow what are the displayed text, labels, casing of characters in the sample output. OUTPUT 1: Enter Grade 1: 70 Enter Grade 2: 80 Enter Grade 3: 90 Average Grade: 80 Remark: Passed OUTPUT 2: Enter Grade 1: 50 Enter Grade 2: 60 Enter Grade 3: 70 Average Grade: 60 Remark: Failed
Write a program that generates a random number in the range from 1 through 100 After generating the random number, the user is to guess the number. If the user’s guess is higher than the random number, the program should display “Too high, try again” If user’s guess is lower than the random number, the program should display “Too low, try again”. If the user guesses the number, the program should congratulate the user and then generate a NEW random number so the game can start over.
