The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.

Start by adding the numbers to get 30.

Now, divide by the number of numbers in the set.

So we have 30 ÷ 6 which is 5.

So the mean is 5.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
