Variable a is 4 more than variable b. variable a is also 1 less than b. which of the following pairs of equations best models the relationship between a and b? 1.a = b 4 a = b − 1 2.a = 4b a = b 1 3.b = a 4 b = a − 1 4.b = 4a b = a 1

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.)

Elizabeth claims that the fourth root of 2 can be expressed as 2^m since (2^m)^n = 2. find the values of m and n for the case where elizabeth's claim is true.
