As a construction engineer for a city, you are responsible for ensuring that the company that is providing gravel for a new road puts as much gravel in each truckload as they claim to. it has been estimated that it will take 500 truckloads of gravel to complete this road, so you plan to measure the volume of gravel in an srs of 25 trucks to make sure that the company isn't delivering less gravel per truckload than they claim. each truckload is supposed to have 20 m3 of gravel, so you will test the hypotheses 0 : 20 : 20 h versus h p a p at the d = 0.05 level.

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
