Electricity bills: According to a government energy agency, the mean monthly household electricity bill in the United States in
liberstina [14]

The 9th percentile of the bill amounts is 81.0634.

<h3>How to calculate the percentile?</h3>

Population mean, µ = 110.56

Population standard deviation, σ = 22

a) p = 0.09

Z score at p = 0.09 using excel = NORM.S.INV(0.09) = -1.3408

Value of X = µ + z*σ = 110.56 + (-1.3408)*22 = 81.0634

9th percentile = 81.0634

b) p = 0.66

Z score at p = 0.66 using excel = NORM.S.INV(0.66) = 0.4125

Value of X = µ + z*σ = 110.56 + (0.4125)*22 = 119.6342

66th percentile = 119.6342

c) Median = 0.50

Z score at p = 0.5 using excel = NORM.S.INV(0.5) = 0

Value of X = µ + z*σ = 110.56 + (0)*22 = 110.56

Median = 110.56

1/8(-8c+16)-1/3(6+3c)
Misha Larkins [42]
\frac{1}{8}(-8c+16) - \frac{1}{3}(6+3c)

This may look scary, but all you have to do is distribute, first:
(-c+2)-(2+c)

Now it's much easier (remember to distribute the negative):
-c+2-2-c = -2c

So, the entire thing simplifies to -2c. NEAT!
