(b) calculate the length of the garden edge if the radius of the circle is 3 metres.

Multiplying an even number of negative numbers gives an answer that is choose from:

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

Solve the equation. 2x - 8(x+1)= 6(2x - 3)
