2. At the lake, Curtis caught three fish. He wanted to weigh the fish individually, but his
scale was broken--It could only read weights
between 5 and 10 pounds. So he weighed the
large and medium fish together, and got 7.8
pounds. The large and small fish weighed 7.0
pounds, and the small and medium fish were
5.6 pounds. How much did each fish weigh
individually?
Write your answer as a decimal.

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

(x-5)1/2+5=2 what is possible solution of this equation

F(x) = 2x + 1? h(x) = x – h(x) = x + h(x) = x – 2 h(x) = x + 2
