Add them all up: 86+90+93+85+79+92=525
divide by 6 (because they provide 6 percentages): 525/6
mean=87.5

4 0

86+90+93+85+79+92=525 divided by 6 is 87.5

The average is 87.5

(Add up all of the numbers and divide it by how many numbers there are)

X + 14 + x + 14 = 17 + x + 7
2x + 28 = 24 + x
2x - x = 24 - 28
x = -4

DF = x + 14
= (-4) + 14
= 10

Since "a" is on the top and the bottom, you can simplify that

$\frac{a^2b^2}{ac}$

$\frac{ab^2}{c}$
