2) Find the sum: 140

3) Divde 140 by the total numbers: 18.769875523239

Range: 20

Largest Number: 31

Smallest Number: 11

Divide: 140/7  and get 20

So to find average, we add up the values, and divide it by how many values there are in total.

27 + 12 + 31 + 19 + 23 + 11 + 17 = 140.

There are 7 numbers. Which means we divide 140 by 7.

140 / 7 = 20 is the average.

Also, if you notice, most of the numbers "kind of" circulate around 20.

Answer:

A.

Step-by-step explanation:

Substituting the ordered pairs into the equation. 3x - y/4 = 11

For (3,-8)

3 * 3 - (-8)/4

9- (-2) = 11

For (4, 4)

3 * 4 - 4/4

12 - 1 = 11

Both ordered pairs equals to 11, therefore, they're both solutions to the equation.

Area to build on: 185 x 230 = 42,550 square feet.
