Ahiker standing at point g wants to estimate the distance across the lake to point h, which is directly north of her location. she walks 650 feet west to point f. she measures the angle from point f to point h to be 84º north of east. find the distance across the lake to the nearest tenth of a foot.

8000 + 8800 + 8000 + 8 million + 80 trillion + another a katrillion equals

Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?

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
