Question
Solution 1
The original total sum of the 20 numbers is 20 * 40 = 800.
When you remove the numbers 25 and 55, the new total sum becomes 800 - 25 - 55 = 720.
The new list now has 20 - 2 = 18 numbers.
So, the new average is 720 / 18 = 40. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study problem. Knowee AI StudyGPT is a powerful AI-powered study tool designed
