Answer 1

7.

Explanation:

Answer 2

the mean is 7

Brief explanation:

To find the Mean of a set we add all the numbers first.

Remember that the Mean relies on a sum.

So we just add up 2 + 10 + 9 = 21

Then divide 21 by 3 (3 because there are 3 numbers in this set) :

21 : 3 = 7

so how do we find the Mean?

We take all the numbers in the set, and divide by how many numbers we have in this set.
