Nolan is filling a small kiddie pool that is 18 inches deep. He notices that it takes two minutes to fill the pool with three inches of water. How many minutes will it take Nolan to fill the pool if it continues at the same rate

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
