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…

The Café Noir Coffee Shop wants some market research on its customers. When a customer places an order, a clerk asks for the customer’s zip code and age. The clerk enters that data as well as the number of items the customer orders. The program operates continuously until the clerk enters a 0 for zip code at the end of the day. When the clerk enters an invalid zip code (more than 5 digits) or an invalid age (defined as less than 10 or more than 110), the program reprompts the clerk continuously. When the clerk enters fewer than 1 or more than 12 items, the program reprompts the clerk two more times. If the clerk enters a high value on the third attempt, the program accepts the high value, but if the clerk enters a negative value onthe third attempt, an error message is displayed and the order is not counted. At the end of the program, display a count of the number of items ordered by customers from the same zip code as the coffee shop (54984), and a count from other zip codes. Also…

A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.arrow_forward
- In Python Write the following application on a separate .py document. Write a program that computes the fuel efficiency for a multi-leg journey. The program will first prompt for the starting odometer reading and then get information about a series of legs. For each leg, the user enters the current odometer reading and the amount of gas used (separated by a space). The user signals the end of the trip with a blank line. The program should print the miles per gallon achieved on each leg and the total MPG for the trip.arrow_forwardJava Language The company will held its quarterly performance for each department; wherein each group of the department are rated from 1 to 5, where 1 is the lowest score and 5 is the highest score. The department has two groups, groupA and groupB. Each group will be rated by five evaluators. Create a program that will ask for the input rate of the evaluators, and determine the group that got the highest rating, as well as the overall rating of the department. Use the UML diagram below as a reference. Department() – accepts 5 ratings of the evaluators and determines the groupScore which is the total rating of the group. getGroupAverage() – returns the value of groupAverage which is the average score of the group. displayAverage() – displays the overAllAverage which is the average of the whole department. overAllScore is the over all score of the department.

They have ten attempts (or rounds) to reach 500 points to win. Each round, the player "bets" some amount of points. See gameplay as follows: A HIGH/LOW ROUND (1) The player is shown an initial random card.Cards have a value from 2-14; however, these values are converted to a string as follows: 2-9 are converted to their string equivalent "2", "3", ... "9"10 is "T", 11 is "J", 12 is "Q", 13 is "K" and 14 is "A" (2) After the play sees the first card, they should guess if the next card will be higher (i.e., greater than the current card) or lower (i.e., a lower value than the first card).They will do this by inputting "H" or "L" (lowercase "h" and "l" will also be accepted as valid input).

The bet must be between 1 and the total amount of points the player has.1 (4) After the bet amount is…arrow_forwardProblem: A small company needs an interactive program to compute an employee’s paycheck. The payroll clerk will initially input the data, and given the input data, an employee's wage for the week should be displayed on the screen for the payroll check. The data for the employee includes the employee's hourly pay rate and the number of hours worked that week. Wage is equal to the employee's pay rate times the number of hours worked (up to 40 hours). If the employee worked more than 40 hours, wage is equal to the employee's pay rate times 40 hours plus 1½ times the employee's pay rate times the number of hours worked above 40. Instructions: Match the action at the left-side with the correct step number at the right-side (the attached picture). Note that it may be possible to group more than one related actions in the same logical step / process without altering the essence of the algorithm. In the program flow, input and checking of hourly pay rate should come before that of the number…arrow_forward
- 1. Write a pyrhon program that prints out a classic hangman stick figure. The program should ask the user to enter a number from 1-6 and the corresponding hangman should be printed. The value the user inputs corresponds to the number of incorrect guesses in a real hangman game and so the completeness of the hangman will correspond to the number of ‘incorrect guesses’ inputted by the user (e.g., if the user enters 1, then only the head of the hangman will be printed; full example below). Example:Enter a number from 1-6: 1O Enter a number from 1-6: 2O|Enter a number from 1-6: 3O\||Enter a number from 1-6: 4O\|/|Enter a number from 1-6: 5O\|/|/Enter a number from 1-6: 6O\|/|/ \ 2. Modify your program from problem 1 so that the user input is checked to be a validsingle digit (1-6) before printing the corresponding hangman. If the input is not valid, theninstead of a hangman the following message should be printed “Invalid input: you must enter asingle number from 1-6.” Example:Enter a…arrow_forwardPython please: Given an integer representing a 10-digit phone number, output the area code, prefix, and line number using the format (800) 555-1212.

For example, if the input is 8005551212 the output is phone_number_tuple: ('8', '0', '0', '5', '5', '5', '1', '2', '1', '2') Formatted phone number: (800) 555-1212arrow_forwardQuestions 1.
