Ascientist observed a snail for two hours. in the first hour, the snail crawled 2.25 inches, and in the second hour it
crawled 3.75 inches.
if there are 12 inches in one foot, how many feet did the snail crawl in total during the two hours?
0.5 feet
1.5 feet
6.0 feet
72.0 feet

Let w=23 . what is the value of w + 45 ?

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.)
