The height of a wave in California varies directly with the seconds that pass by. At 4 seconds, the wave is 6 feet high. Find the constant of the variation. (do not use spaces in your answer; fractions should be in simplest form; use the / for your fraction bar)

Question: what is the value of x 4x-2= (-7) +5x. it would be greatly appreciated if someone could actually explain to me step by step

Factor this polynomial completely x^2-64

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.)
