What is the speed from 8s-10s? (Think of calculating the slope)
4 m/s
8 m/s
2 m/s
16 m/s

Which expression is equivalent to 8(k + m) − 15(2k + 5m)?

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

What ia the sum if the first 7 terms of the geometric series
