Question

These are the ages of the members of Dion's swim team. The mean age is 10.

Answer 1

Answer: The mean of the list given is 10.

To find the mean of a list of numbers, first add up all the numbers.

10 + 10 + 11 + 9 = 40

Now, divide the list by the total number of people.

40 / 4 = 10

The mean of this list is 10.
