Given that d is the midpoint of ab and k is the midpoint of bc, which statement must be true? a lines has points a, d, b, k, and c. db = bk b is the midpoint of ac. d bisects ak. ak + bk = ac

Solve 2x+y=3 x+y=5 in substitution method

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.)
