Question 1 Report

Find the mean of 10, 8, 5, 11, 12, 9, 6, 3, 15, and 23.
Answer Details
To find the mean of a set of numbers, you add up all the numbers and then divide by the total count of numbers. So, for the given set of numbers, we add them up: 10 + 8 + 5 + 11 + 12 + 9 + 6 + 3 + 15 + 23 = 102 There are 10 numbers in the set, so we divide the sum by 10: 102 ÷ 10 = 10.2 Therefore, the mean of the given set of numbers is 10.2. So the answer is 10.2.
