A small cube with side length 6y is placed inside a larger cube with side length 4/2. What is the difference in the volume of the cubes?
• (4x2 -by) (16** +24x2y+38y?)
• (63-4x2) 36y2 +24x+y+ 16x
• (4x2-by)(4x4 +24x+y+by?)
• (4x2 + 8y)(18** – 24x+y+38y?)

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
