Step-by-step explanation:
Given

The probability density of the volume of the cube
The volume of a cube is:

For a uniform distribution, we have:

and

implies that:

So, we have:

Solve


Recall that:

Make x the subject

So, the cumulative density is:

becomes

The CDF is:

Integrate
![F(x) = [v]\limits^{v^\frac{1}{3}}_9](https://tex.z-dn.net/?f=F%28x%29%20%3D%20%5Bv%5D%5Climits%5E%7Bv%5E%5Cfrac%7B1%7D%7B3%7D%7D_9)
Expand

The density function of the volume F(v) is:

Differentiate F(x) to give:




So:

The distance between points (-6,8) and (-3,9) is 9 units

Answer:
5/9 of the area of square ABCD is shaded
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
To find out what fraction of the area of square ABCD is shaded, divide the shaded area by the total area of square ABCD
step 1
Find out the area of square ABCD
The area of a square is

where
b is the length side of the square
we have

so


step 2
Find out the area of the 4 congruent right triangles
![A=4[\frac{1}{2}(x)(2x)]=4x^{2}\ units^2](https://tex.z-dn.net/?f=A%3D4%5B%5Cfrac%7B1%7D%7B2%7D%28x%29%282x%29%5D%3D4x%5E%7B2%7D%5C%20units%5E2)
step 3
Find out the area of the shaded region
The area of the shaded region is equal to the area of square ABCD minus the area of the 4 congruent right triangles
so

step 4
Divide the shaded area by the total area of square ABCD

therefore
5/9 of the area of square ABCD is shaded
