PLEASE HELP!!! Mr. Abernathy had to go to Truth or Consequences, New
Mexico. On the way there, he encountered all kinds of
problems (bad weather, road construction, and so on), so
his speed was a measly 45 mph. On the way back, he
followed the same route, but this time he was able to
travel at a speed of 63 mph. If the total round trip took
12 hours, how many hours did it take Mr. Abernathy to
drive from his house to Truth or Consequences?

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.

The first-serve percentage of a tennis player in a match is normally distributed with a standard deviation of 4.3%. if a sample of 15 random matches of the player is taken, the mean first-serve percentage is found to be 26.4%. what is the margin of error of the sample mean? a. 0.086% b. 0.533% c. 1.11% d. 2.22%
