Find the average of these numbers. 12, 9, 11, 8, 9, 12, 9 a) 8 b) 9 c) 10 d) 12

Hi there,

So basically finding the average is adding up all the numbers and dividing that total by how many numbers there are.
So with this problem it would be:
12+9+11+8+9+12+9=70
Then divide it by 7 because there are 7 numbers
70/7=10

Therefore the average is 10.

Hope this helps!

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
