Question
Re-write the
Problem
Create an algorithm that will calculate the average of a group of numbers that are input and print the average.
Calculate_Average
1 Get num1, num2, num3
2 sum = num1 - num2 + num3
3 average = sum/4
4 print average
Expert Solution

arrow_forward
Step 1
Average of a group of numbers = ( sum of all the numbers ) / ( count of Numbers ) .
so, For Above Case :
Average = ( num1 + num2 + num3 ) / 3 .

- Computer Science Write correct Python code to complete the following task. Document all assumptions. Solutions that do not incorporate a loop will receive a grade of 0. Obtain a positive integer greater than 1 but less than 20 from the user. Calculate the product of all numbers starting from the user's number up to, and including 100. If the number is evenly divisible by 7, do not include it in the product. If the product is more than or equal to 5000 stop the loop early and show the message "a big product". When the loop ends, if the product is less than 5000 show the product to the user.arrow_forwardUse the left to right addition method as outlined in the module to add the numbers.
