Question 1 Report

The arithmetic mean of 5, 8, 10, 15, 24 and 28 is_______

145

15 Correct answer

Answer Details

To find the arithmetic mean of a set of numbers, you need to add up all the numbers and divide the sum by the total number of numbers. In this case, we have six numbers, so we need to add them up and divide by 6. Adding up the numbers, we get: 5 + 8 + 10 + 15 + 24 + 28 = 90 Then, we divide the sum by the total number of numbers: 90 / 6 = 15 Therefore, the arithmetic mean of 5, 8, 10, 15, 24 and 28 is 15.
