Express the edge length of a cube as a function of the cube's diagonal length d. Then express the area and volume of the cube as a function of the diagonal length.

Step-by-step explanation:

d² = x² + x² + x²

d² = 3x²

d²/3 = x²

x = √(d²/3)

x = d√(1/3)

x = (d/3)√3

A = 6x²

A = 6((d/3)√3)²

A = 6(((d²/9)3)

A = 2d²

V = x³

V = ((d/3)√3)³

V = ((d³/27)3√3)

V  = (d³/9)√3

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
