A man is standing on the top of a 15 foot ladder, which is leaning against a wall. Some scientific minded joker comes up and starts to pull the bottom of the ladder away at a steady rate of 6 ft/min. At what rate is the man on the ladder descending if he remains standing on the top rung when the bottom of the ladder is 9 ft. from the wall?

where are the choices?

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
