So you have to fine the total volume of the pool which is 1274 feet. then multiply that by 7.48 to get 9529.52. so thats how much water is held in the pool at 100%. so now you can divide 9529.52 by 10 to get you 10% of the pool which is 952.952. then multiply that by 8 to get 7623.616 gallons of water. and thats your answer.

The volume of the water in the pool is (24.5 x 13 x 4) cubic feet.

The number of gallons is (24.5 x 13 x 4 cubic feet) x (7.48 gal/cu-ft)

80% means 0.80 .

To fill the pool to 80% of capacity, it takes

(0.8) x (24.5 x 13 x 4 cubic feet) x (7.48 gal/cu-ft) gallons.

Answer:

0.0803 = 8.03% probability that the number who have a high school degree as their highest educational level is exactly 32.

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they have a high school degree as their highest educational level, or they do not. The probability of an adult having it is independent of any other adult. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
