Aquadrilateral has two pair of opposite parallel sides. each of one
pair of parallel sides is 4 yards long. each of the second pair of sides
is 8 yards long. a diagonal connecting the opposite corners of the
quadrilateral is 9 yards long. is the quadrilateral a rectangle? prove
that your answer is correct.

What is the solution to the system of the equations? x = y - 3 x + 3y = 13

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.)
