Answer:
The variance of the data is 15.
σ² = 15
Step-by-step explanation:
The mean is given as
X = 8
х | (x - X) | (x - X) ²
12 | 4 | 16
9 | 1 | 1
11 | 3 | 9
5 | -3 | 9
3 | -5 | 25
The variance is given by
Therefore, the variance of the data is 15.

Given:
The base of the prism is a right triangle with legs 1 m and 2 m.
The height of the prism is 17 m.
To find:
The volume of the given prism.
Solution:
The area of a triangle is:
So, the area of base of the prism is:
Now, the volume of the prism is:
Where, B is the base area and h is the height of the prism.
Substituting , we get
The volume of the prism is 17 cubic m. Therefore, the correct option is (d).
