3. The Math subtraction learning tool program generates just one question for each run. You can use a loop to generate questions repeatedly. Therefore, write a program that generates five questions and reports the number of the correct answers after a student answers all five questions. (The output of your program should be like the following but you should try different numbers) What is 9 -27 7 You are correct! What is 307 3 You are correct! What is 3 27 1 You are correct! What is 7- 47 4 Your answer is wrong. 7- 4 should be 3. What is 757 4 Your answer is wrong. 7- 5 should be 2 Correct count is 3 Test time is 1021 seconds 9-2-7 correct 3-0-3 correct 3-2-1 correct 7-4-4 wrong 7-5-4 wrong
(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.
1. Write a program called NumberGuess to play the number guessing game. The program shall generate a random number between 0 and 99. The player inputs his/her guess, and the program shall respond with "Try higher", "Try lower" or "You got it in n trials" accordingly.
Accumulating Totals in a Loop Summary In this lab, you add a loop and the statements that make up the loop body to a Java program that is provided. When completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. Your loop should execute until the user enters the character X instead of L for left-handed or R for right-handed. The inputs for this program are as follows: R, R, R, L, L, L, R, L, R, R, L, X Variables have been declared for you, and the input and output statements have been written. Instructions Ensure the file named LeftOrRight.java is open. Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class. Execute the program by clicking Run and using the data listed above and verify that the output is correct.
Three numbersa. Write a program that reads three numbers and prints “all the same” if they are allthe same, “all different” if they are all different, and “neither” otherwise.b. Write a program that reads three numbers and prints “increasing” if they are inincreasing order, “decreasing” if they are in decreasing order, and “neither”otherwise. Here, “increasing” means “strictly increasing”, with each value largerthan its predecessor. The sequence 3 4 4 would not be considered increasing.c. Repeat part b. but before reading the numbers, ask the user whetherincreasing/decreasing should be “strict” or “lenient”. In lenient mode, thesequence 3 4 4 is increasing and the sequence 4 4 4 is both increasing anddecreasing
Use While loop to solve the problems Note: Python language for solution 4. Write a program that uses a while loop, the program should do the following: The program should repeatedly read numbers until the user enters "done". Once "done" is entered, print out the total, count, and average of the numbers. 5. Write a program to find the sum of even numbers until n, where n is an int entered by the user, example: n = 11, sum = 2+4+6+8+10, sum = 30.
By using while loop OR do..while loop, write a program that displays a list of groceries. Then, allow user to insert number of product that they want to buy, the item's code and quantity for each item. Finally, display the total price that the user needs to pay. Valid input for the number of product and quantity is positive number. Meanwhile valid number for items' code is only from 1 to 4. 1 Cooking oil 2 Curry powder RM 3.40 3 Detergent Potato chips RM 2.50 RM 8.50 4 RM 3.20 Sample output Emer number of product that you want to purchase (press 0 to exit) : 2 1.Enter item's code that you want to buy : 3 1.Enter the quantity of item that you want to buy: 1 2.Enter item's code that you want to buy : 0 2.Enter the quantity of item that you want to buy: 0 2.Enter item's code that you want to buy : 1 2.Enter the quantity of item that you want to buy; 2 Total price is RM 13.50

1. Write a program that asks the user for the price of several items sold until the user answers with an “N”. The program should accumulate the total of all prices entered. After the loop is finished, the program is to compute the sales tax of all items as 7% [0.07]. Finally, the program is to print out the total of the items, the sales tax due, and the total amount due on three separate lines.
