marta [7]

Answer:

The probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772

Step-by-step explanation:

The average monthly household cellular phone bill is $73.

$\mu = 73$

Local monthly household cell phone bills are normally distributed with a standard deviation of $11.

$\sigma = 11$

We are supposed to find the probability that a randomly selected monthly cell phone bill is less than $95 i.e.P(x<95)

$Z=\frac{x-\mu}{\sigma}$

$Z=\frac{95-73}{11}$

Z=2

Refer the z table for p value

So,p value = 0.9772

Hence the probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772

Kevin can travel 22 1/2 miles in 1/3 hour .What is the average speed in miles per hour?

Fantom [35]

You can choose to answer this with fractions or decimals. I'll choose fractions because we won't need calculators. 22 1/2 miles "in" 1/3 hour, means 22 1/2 mi divided by 1/3 hour.
22 1/2 = [(22×2) + 1] ÷ 2 = 45/2
So (45/2)mi ÷ (1/3)hr is the same as (45/2) × (3/1), or (45×3)/2 = 135/2, which is 67 1/2, or 67.5 mi/hr (mph).
