Ceecee recorded the number of necklaces for sale at 10 different locations and then arranged the numbers from smallest to largest. the numbers of necklaces for sale at the locations were 4, 4, 4, 5, 8, 9, 9, 9, 9, and 9.the mean number of necklaces for sale at the locations was 7.
what is the mean absolute deviation?
a.0
b.2
c.2.2
d.4.4

The answer is 2.2
To find the answer you need to find the distance between the mean and the number set(distance between 7 and 4 is 3 and so on..) once you have done this for every number add them up and divide it by how many numbers there are in the set.(In this case 10) and you should get your answer.(2.2)
Hope this helps!

answer:
congruent segments
step-by-step explanation:
congruent segments. take a line, cut it in half, superipose one half over the other half; you'll have congruence.

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
