Write a Python application for the following scenario. You have some students in your Introduction to Python Programming class. Write an interactive program that asks the user to input the names of each student and then their grades. Each student inputs three grades (Exam 1, 2 and 3 (you can create categories of your choice)). Calculate the total scores of each student. With the data that you have collected, please create a graph (pie chart or column charts) with the information of your students. Try to use data labels for your program. Please follow the rubric and submit everything as required. Hint: Use any of the concepts that you have learnt through the course. You can use methods, lists, or anything that you would find necessary to create the solution.
In various applications, you are often asked
to compute the mean and standard
deviation of data. The mean is simply the
average of the numbers. The standard
deviation is a statistic that tells you how
tightly all the various data are clustered
around the mean in a set of data. For
example, what is the average age of the
students in a class? How close are the ages?
If all the students are the same age, the
deviation is 0.
Write a program that prompts the user to
enter any number of values into a double
array, and then calculates and displays the
mean and standard deviations of these
numbers using the following formulas:
(z - mean)
z+z3+ *** +zn deviation =
mean =
n-1
Required Methods
You must write your program so that the
following methods are defined/implemented
and used (called):
• /* Compute the deviation of
double values */
public static double
deviation (double[] x)
• /* Compute the mean of an array
of double values */
public static double

If you are not sure where to begin, think of a task that you repeat often in your major that would benefit from a program. For example, chemistry unit conversions, finding the area for geometric shapes, etc. You can also create an interactive story that changes based on the user input/decisions. The possibilities are endless. The program must include instructions for the user. Be in the mindset that the program you develop will be used by anyone. You will not receive any assistance from the instructor. It is up to you to figure out your program. Your program must include (but not limited to) the following: • Comments • Input(s) and output(s) • Decision structures • Loops Be as creative as possible!arrow_forward
- Congrats! You work for Zillow now. Your first task is to write an algorithm that recommends apartments based on a user’s preferences. Zillow offers the following three properties for rent: Apartment A – 600 square feet, pets allowed, $1400/month Apartment B – 800 square feet, no pets, $1600/month Apartment C – 1000 square feet, pets allowed, $1800/month Write an algorithm for a program that does the following: Prompt the user for the minimum square footage they will accept, how many pets they have, and the maximum price they’d pay per month, and then calculate and output the apartments that match their preferences. If there is no apartment that matches their preferences, print out "No matches, sorry!". Make sure the inputs are valid--negative square footages, prices, and pet numbers don’t make sense!arrow_forwardWrite a program that deals a number of cards (their numerical values) to a player's hand. To begin, the program asks the player for the values of the deck of cards. Then, the program deals the first two cards of the deck to a player's hand, and asks him if he wants another card. If he does not want a card, the program ends. If he wants a card, the program deals the next available card in the deck, adds it to the player's hand, and asks the player if he wants another card. The dealing process repeats as long as the user continues to accept cards, or until the cards in the deck run out. Card dealing involves copying the available card from the deck vector to another vector, which stores the player's hand, at the next available position. Assume that the deck of cards consists of only 10 cards with numerical values from 1 to 10, which the player will enter by keyboard before the program deals. The following functions must be implemented/used: enterDeckValues. - This…arrow_forwardA 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. Instruction: Rank the given pseudocodes according to their order of action: If employee’s number of hours worked is less than 0, go to 5 Set employee’s hourly pay rate to 0 Set employee’s number of hours worked to 0 Print “Employee’s wage is ”, employee’s wage Else, employee’s wage = employee’s hourly pay rate x hours Else, go to 5 Else, go to 8 Get employee’s hourly pay…arrow_forward
- Please type thank you! Tasks: 1. Write a python program that implements the estimation of Pi through a Monte Calo simulation. Describe how Pi is being estimated in this simulation. How many iterations do you need to run? In your own words, make a case for when it is a good approximation of Pi. d. Suggest a method that would accelerate the approximation of Pi. You may either suggest a method that would accelerate the approximation of Pi than the method you described in b, or you may describe two methods and explain which one can accelerate the approximation of Pi than the other one.arrow_forwardJava program help Simulate a slot machine. The customer will add a fixed amount of money to the machine and play the slots. There should be 4 images for the game: "Apple", "Orange", "Banana", and "Cherry". If three of the images match, the customer wins $2 and is added to their balance. If all four match, the customer wins $10 and that is added to their balance. If less then four match there is no prize money, and the customer is charged $1 for the try. The customer can quit after each try, and the program will print out the customer's cash balance. Coding Details: Use an array of strings to store the 4 strings listed above. Use a do-while loop for the program. The program starts once the user enters how much money they have. The decision to stop occurs at the bottom of the loop. The do-while loop keeps going until the user quits, or there is no money left.

For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure. (Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.) Here are sample runs of the program: Sample 1: Enter a point with two coordinates: 2 2 Point (2.0, 2.0) is in the rectangle Sample 2: Enter a point with two coordinates: 6 4 Point (6.0, 4.0) is not in the rectangle Analysis: (Describe the problem including input and output in your own words.)
