Find the mean of 8, 7, 9 graphically.
What is the sum of the numbers?

Sum=24

Mean=8

Step-by-step explanation:

To find the sum of all the numbers you simply would do 8+7+9.

That is 24.

When finding mean you add up all your numbers then divide by the total number of number (I know that sounds a bit confusing. In this case there are only 3 numbers, so that is the one you will use for dividing)

Your equation would look like this

24

_

3

Once you divide you should get 8 as your mean or average in other terms.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
