In the US, 21% of households use a clothesline to dry their laundry. Capucine would like to survey households that use a clothesline, so she plans to contact randomly selected US households until she finds ones that use one. Let F be the number of households Capucine contacts to reach the first household that uses a clothesline. Find the mean and standard deviation of F. Find the mean and standard deviation of F ANSWER: Mean: 4.84
Standard deviation: 4.24

.25

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
