Does anyone know what number 7 is I’m very confused.

Step-by-step explanation:

Because the mean is simply the mathematical average of all the points, simply add all the prices and divide by the amount of prices, or 10.

100 + 150 + 80 + 240 + 130 + 170 + 210 + 165 + 275 + 90 = 1610, then divide by 10 to get 1610 / 10 = 161.

Because there is a absolute deviation of 50 from the mean, simply subtract and add fifty to learn that the least they will pay is $111, and the most they will pay is $211, and 5 prices fall within this range.

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
