What is the mean number of people in each age range? explain

To find the mean you add up all the numbers then divide the sum by how many numbers there are :

8+16+12+11+8=55

there are 5 numbers in the equation so you divide 55 by 5 :

55÷5= 11

the mean is 11

hope this helped

Ok so 8,16, 12, 11, and 8 you would add those up and you get 55

the following examples illustrate the associative property of multiplication.

(5 · 3) · 6 = 5 · (3 · 6)

2 · (1.1 · 0.1) = (2 · 1.1) · 0.1

both are the examples of associative property of multiplication.

general form of associative property

(a*b)*c = a * (b * c)

second example is in reverse form when compared with general form of associative property.

so first example best describes the associative property.
