What should be done first to evaluate the expression? 8 × 4 ÷ 3 + 52 - 8

Divide 4 by 3
Square 5
Add 3 and 5
Multiply 8 and 4

(and its not 52 its just the 2 is suppose to be up)

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

The volume of a spherical hot air balloon v(r) = 4 3 ? r3 changes as its radius changes. the radius is a function of time given by r(t) = 3t. find the instantaneous rate of change of the volume with respect to t at t = 2.

Apply the distributive property to write an expression that is equivalent to 5h + 2hsquared2.
