The lifespans of zebras in a particular zoo are normally distributed. The average zebra lives 20.520.520.5 years; the standard deviation is 3.93.93.9 years. Use the empirical rule (68-95-99.7\%)(68−95−99.7%)(68-95-9 9.7%) to estimate the probability of a zebra living between 16.616.616.6 and 24.424.424.4 years.

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

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
