Manuel bought a balloon (that is a perfect sphere) with a radius of 2 cm. he wanted his balloon to be bigger, so he blew 2 big breaths of air into the balloon. each big breath increased the balloon's radius by 1 cm. what is the ratio of the current volume of the balloon to the original volume?

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
