Marcus was asked to identify the vector that maps (triangle) def to (triangle) d'e'f'. he drew a vector as shown and determined that the component form of
the vector is (3, 1). explain his error.
(there is grid to show u what it looks like on graph paper) i need asap!

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
