Using Paython Write a program that asks a student for his grade (out of 100) in 3 exams and then print out his final grade (out of 100), given that the weight of the first exam is 30%, the second 30%, and the third 40%. Example Input: Exam1: 70 Exam2: 80 Exam3: 90 Example Output: Total Grade = 81 Explanation: 0.3 * 70 + 0.3 * 80 + 0.4 * 90 = 81

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.

At a certain university, students have to submit their exams online. The administration decides that for each minute of late submission, 5 points are deducted. Write a program that asks the user for his initial grade and the late submission time (in minutes), and then displays the final result. Sample Run 1: Enter your initial grade: 82 Enter the late submission time (in minutes): 6 Your final grade is 52 Sample Run 2: Enter your initial grade: 115 Grades should be between 0 and 100 Sample Run 3: Enter your initial grade: 43 Enter the late submission time (in minutes): 10 Your final grade is 0

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: mean)? 2i +x2 + .. + xn i=1 i=1 mean = deviation = п - 1

Python programming In a department store sale, customers who purchase over 2000 are given 10% discount. Write a program that will accept for the purchase amount of a customer, solve for his/her discount if there’s any, ask for the money he/she is going to pay, then output the discounted price and the change of the customer.”
USE PYTHON A small shop sells 280 different items. Each item is identified by a 3 – digit code. All items that start with a zero (0) are cards, All items that start with a one (1) are sweets, All items that start with a two (2) are stationery and All items that start with a three (3) are toys. Write a program which inputs the 3 – digit code for all 280 items and outputs the number of cards, sweets, stationery and toys.
Write a program which prompts the user to enter an integer and prints a half diamond star pattern. Note: you can assume that the number will always be > 1. For example: Input Result 5 9 Enter number of columns: 5 * ** *** **** ***** **** *** ** * Enter number of columns: 9 * ** *** **** ***** ****** ******* ******** ********* ******** ******* ****** ***** **** *** ** * Answer: (penalty regime: 0.0 5 10 15 20 25 30 35 40 45 50 %)
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
Write a program that calculates the equivalent resistance of a circuit. n electrical resistors with resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied across each. Their equivalent resistance Reg is related to the values R1, R2, ..., Rn by: 1 1 1 1 + +...+ R R R, R. "eq Write a program that prompts the user to enter the resistance of n resistors. The user should be prompted continuously by using a while loop until a zero or negative value is entered (the program should count the number of resistors n entered by the user and store the values in an array). Use another separate loop to print the resistance values entered by the user and the equivalent resistance Reg. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.
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
Statistics are often calculated with varying amounts of input data. Write a program that takes any number of integers as input, and outputs the average and max. Ex: If the input is: 15 20 0 5 the output is: 10 20 My Code: data = input("")data = data.split(" ")count = 0total = 0max = -99999 for val in data:total += int(val)count += 1 if int(val) > max:max = valavg = total/count print(int(avg), max) This code doesnt produce the correct MAX needed the out oupt for this code is. 10 5 should be 10 20
