A crayon manufacturer is comparing the effects of two kinds of yellow dye on the brittleness of crayons. Dye B is more expensive than dye A, but it is thought that it might produce a stronger crayon. Four crayons are tested with each kind of dye, and the impact strength (in joules) is measured for each. The results are as follows: Dye A: 1.3 2.0 1.2 3.0 Dye B: 3.0 3.2 2.9 3.4 Can you conclude that the mean strength of crayons made with dye B is greater than that of crayons made with dye A? Compute the P-value and state a conclusion. Since , we conclude that the mean strength of crayons made with dye B is greater than that made with dye A.

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
