### Instruction: What is the average (mean) of the numbers 6, 8, 9, 11, and 16?### Response: 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.
