Which of the following numbers is closest to the mean

Hello!

To find the closet number we first need to understand how our data, and how to find the mean.

The mean is known as the average, which we find when we add all of our data up and divide by the number of factors.

In this case, after reading our graph, our data set is equal to:

3,4,4,4,4,5,5,5,5,5,6,6,6,6,7,7,8,9,10,11

When all of these numbers are added we get = 120

120 divided by 20 (the total number of factors) is equal to 6!

Which means that the answer to this question is E. 6

Hope this helps.

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
