(1 point) To estimate the mean height u of male students on your campus, you will measure an SRS of students. Heights of people of the same sex and similar ages are close to Normal. You know from government data that the standard deviation of the
heights of young men is about 2.8 inches. Suppose that (unknown to you) the mean height of all male students is 70 inches.
(a) If you choose one student at random, what is the probability that he is between 64 and 68 inches tall?
(b) You measure 36 students. What is the standard deviation of the sampling distribution of their average height x?
nhilihu that the moon height of your samnle is between 64 and 68 inches?

Acylinder and its dimensions are shown. which equation can be used to find v, the volume of the cylinder in cubic centimeters?

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
