Answer:
-V(X + c) = V(X) + c
Step-by-step explanation:
Using the propierties of the variance:
- <em>The variance of a constant is zero:</em>
<em></em>
<em>
</em>
<em></em>
Where k is an arbitrary constant. So:
-V(c) = 0 is true.
- <em>If all values are scaled by a constant, the variance is scaled by the square of that constant: </em>
<em></em>
<em>
</em>
<em></em>
Where k is an arbitrary constant. Therefore:
-V(cX) = c2 V(X) is true.
- <em>Variance is invariant with respect to changes in a location parameter. That is, if a constant is added to all values of the variable, the variance is unchanged: </em>
<em></em>
<em>
</em>
<em></em>
Where k is an arbitrary constant. Hence:
-V(X + c) = V(X) + c is not true.

We did this same kind of problem in school. All we did was divide the those 2 numbers to figure out the unit price. So, 20/5 = 4 $ per CD.
The other sides will be 16 inches long, because 13-3=10, and 10+6=16
