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.

Answer:
h²⁴
Step-by-step explanation:
Emm... Do you mean (frac(h¹²)/(h⁴))³? If so, here is a solition: h¹²/h⁴=h⁸ and 8×3=24, so answer is h²⁴. Please use formula editor next time) Have a nice day))
M2 + 2d + 8 + d
