a 46 gram sample of substance that'a a by product of fireworks has a k value of 0.1368 N = N0e -kt N0 = initial mass ( at time t =0)
N= mass at time t
K = a positive constant that depends on the substance itself and on the units used to measure time.
t = time in days
find the substances half life, in days. round your answer to the nearest tenth.

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

Which will form a composite function?
