Which statement best describes a strategy for estimating the perimeter of the figure below if the grid squares have side lengths 1 cm? On a coordinate plane, a figure has a side lengths of 2 units, 5 units, 4 units, and 4 diagonal units. Add the lengths of the horizontal and vertical segments, and then subtract 5 because the diagonal side is 4 units wide and 2 units tall. Add the lengths of the horizontal and vertical segments, and then subtract 3 because the diagonal side is 4 units wide but only 2 units tall. Add the lengths of the horizontal and vertical segments, and then add 3 because the diagonal side is 4 units wide but only 2 units tall. Add the lengths of the horizontal and vertical segments, and then add 5 because the diagonal side is 4 units wide and 2 units tall.

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
