The length of a rectangle is 3 times its width. What is the length of the rectangle if the area is 48 square centimeters?

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.)

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1
