The figure below shows a shaded rectangular region inside a large rectangle: a rectangle of length 10 units and width 5 units is shown. inside this rectangle is another rectangle of length 6 units and width 3 units placed symmetrically inside the larger rectangle. the smaller rectangle is shaded gray. what is the probability that a point chosen inside the large rectangle is not in the shaded region? answers: 18% 36% 42% 64%

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

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

Iwill give brainliest. suppose tommy walks from his home at (0, 0) to the mall at (0, 5), and then walks to a movie theater at (6, 5). after leaving the theater tommy walks to the store at (6, 0) before returning home. if each grid square represents one block, how many blocks does he walk?
