a) The most common shoe size that appears within the set of data is 3 1/2
b) I'm not sure; but if I had to make an educated guess then the equivalents would be 3 1/2, 4, 7, 5, 5 1/2, 6 1/2, and 4 1/2
c) Part to whole comparison: There are only 2 5s out of the entire set of 16 elements
Part to part comparison: There are 2 5s and 2 7s; same amount
Step-by-step explanation:
The mean absolute deviation is:
MAD = ∑ᵢ₌₁ⁿ│xᵢ − μ│/ n
First, find the mean.
μ = (x + 2x + 3x + 4x) / 4
μ = 2.5x
Now find the mean absolute deviation:
MAD = (│x − 2.5x│+│2x − 2.5x│+│3x − 2.5x│+│4x − 2.5x│) / 4
MAD = (│-1.5x│+│-0.5x│+│0.5x│+│1.5x│) / 4
MAD = (1.5x + 0.5x + 0.5x + 1.5x) / 4
MAD = (4x) / 4
MAD = x

Formula for the circumference of a circle:
C = πd or C = 2πr
[C = circumference π(pi) d = diameter r = radius(half the diameter)]
You know:
d = 5 feet
and you're using 3.14 for π, so substitute/plug it into the equation
C = πd
C = (3.14)(5)
C = 15.7 feet Your answer is B
