What is the average (mean) of the numbers 6, 8, 9, 11, and 16?
I know that the average of a set of numbers is the sum of the numbers divided by the number of numbers. So, to find the average of 6, 8, 9, 11, and 16, I need to add them up and divide by 5, since there are 5 numbers. Adding them up, I get 6 + 8 + 9 + 11 + 16 = 50. Dividing by 5, I get 50/5 = 10. So, the average of these numbers is 10.
