Andrew solved the following inequality, and his work is shown below: −4(x + 8) ≤ −2x + 50 −4x − 32 ≤ −2x + 50 −2x − 32 ≤ 50 −2x ≤ 82 x ≤ −41 What mistake did Andrew make in solving the inequality?

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

You were told that the amount of time lapsed between consecutive trades on the new york stock exchange followed a normal distribution with a mean of 15 seconds. you were also told that the probability that the time lapsed between two consecutive trades to fall between 16 to 17 seconds was 13%. the probability that the time lapsed between two consecutive trades would fall below 13 seconds was 7%. what is the probability that the time lapsed between two consecutive trades will be between 14 and 15 seconds?
