python Write a program that uses a custom function to return the cost of purchasing an item, possibly in multiple quantities. The item might be subject to 7% sales tax. The main function should prompt the user to enter the quantity, unit price, and taxable data. The main function should call the custom function with these three inputs as arguments and print the cost of the purchase in currency format.

(Statistical) In many statistical analysis programs, data values considerably outside the range of the majority of values are simply dropped from consideration. Using this information, write a C++ program that accepts up to 10 floating-point values from a user and determines and displays the average and standard deviation of the input values. All values more than four standard deviations away from the computed average are to be displayed and dropped from any further calculation, and a new average and standard deviation should be computed and displayed.
Domino's Time Function Name: dominosTime() Parameters: N/A Returns: None Description: During the summer, you ordered a lot of food from Domino's. Pizzas are $12, an order of pasta is $6, and chicken wings are $8. Write a function that asks the user how many of each food item they would like, and then print a response telling them what their order to- tal will be. The order total should be an integer. >>> dominosTime() How many pizzas do you want? 3 How many orders of pasta do you want? 2 How many orders of chicken wings do you want? 2 By ordering 3 pizzas, 2 orders of pasta, and 2 orders of chicken wings, your order total comes to $64.
Future Investment Value = investment amount * (1 + monthly interest)^(number of years * 12) Using this formula, write a function in Python called futureValue that prompts the user to enter an investment amount, an annual percentage interest rate, and the amount of years. The function should accept the input as arguments. The interest rate should have a default value of 7%. You can add default values of your choice for the amount of years. This function should print out a table that displays the future values. Demonstrate this function in another function called main. Format your output by two decimal places. Output Example: Enter the amount you want to invest: 1000 [Enter] Enter the interest rate for your investment: [Enter] Enter the number of years you want to invest this money: 30 [Enter] Years Future Value 1 1093.81 2 1196.41 ........ 30 14730.58

helppp meee Instructions: You are provided with the isLeapYear() function which is already declared and defined for you. Your task is to ask the user for a year and then call the isLeapYear function to check whether the year is a leap year or not. Input 1. Year to be checked Output should be like this: Enter year: 2020 2020 is a leap year note: If a certain year is a leap year, print "<INSERT_YEAR_HERE> is a leap year" Otherwise, print "<INSERT_YEAR_HERE> is not a leap year" MY CODE: (IN C LANGUAGE PLEASE) #include<stdio.h> int isLeapYear(int); int main(void) { // TODO: Write your code here return 0;} int isLeapYear(int n) { if( (n % 4 == 0 && n % 100 != 0) || (n % 100 == 0 && n % 400 == 0) ) { return 1; } return 0;}
flowchart for this Design a function named FindMax_697 (where 697 is last 3 digits of your student number) that accepts three integer values as arguments and returns the value that is the highest of the three. Prompt the user to enter three integer values in the main program and pass those values to the function. The function must return the greatest value from the three. Thenyour program should display that greatest value.

FizzBuzz Interview Question Create a function that takes a number as an argument and returns "Fizz", "Buzz" or "FizzBuzz". If the number is a multiple of 3 the output should be "Fizz". If the number given is a multiple of 5, the output should be "Buzz". If the number given is a multiple of both 3 and 5, the output should be "FizzBuzz". If the number is not a multiple of either 3 or 5, the number should be output on its own as shown in the examples below. The output should always be a string even if it is not a multiple of 3 or 5. Examples fizz_buzz (3) "Fizz" fizz_buzz (5) → "Buzz fizz_buzz (15) "FizzBuzz" fizz_buzz (4) "4" 11
C++ coding help Write a program that prompts the user for a positive integer, the first term in a hailstone sequence, and then generates a subsequence from that hailstone number to the next occurrence of 1 in the sequence. The program should also determine and display the sum and length of the subsequence. If the user enters an integer less than 1, the program should display an error message as shown in the sample run. In order for the program to handle large integers, use long rather than int when declaring them.
METHODOLOGY A bookstore owner wants you to write a program that calculates the gross pay of an employee. The input to the program is the number of hours the employee works in one week and the employee’s hourly pay rate. The program is to calculate the employee’s gross pay including the possibility of overtime pay. Regular pay is the number of hours the employee worked (up to 40 hours) times the hourly rate. The program is to compute an overtime pay if the employee worked more than 40 hours. All hours beyond 40 should be multiplied to 1.5 for the OT differential pay The program should output the worker’s regular pay, overtime time, and the gross pay (sum of the regular pay and overtime pay).
