The temperature at the center of the Earth is about 10,832°F. The
temperature at the surface of the sun
is about 900°F cooler than the center
of the Earth. Draw a bar diagram to
show the relationship between the
temperatures of the surface of the sun
and the Earth's center. Then find the
temperature of the surface of the sun.

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
