What is the volume for this triangular prism if the base of the triangle is 8 the height is 16 and the height for the triangle i

insens350 [35]

Answer:

Volume of the triangular prism = 448 cm³

Step-by-step explanation:

Volume of the triangular prism = Area of the triangular base × Height of the triangular prism

Area of the triangular base = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(8)(16)$

= 64 units²

Volume of the triangular prism = 64 × 7

= 448 cm³

The following data values represent a sample. What is the variance of the

xeze [42]

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

$\sigma^2 = \frac{1}{n-1} \sum (x - X)^2$

$\sigma^2 = \frac{1}{5 - 1} (16 + 1 + 9 + 9 +25) \\\\\sigma^2 = \frac{1}{4} ( 16 + 1 + 9 + 9 +25) \\\\\sigma^2 = \frac{1}{4} (60) \\\\\sigma^2 = 15$

Therefore, the variance of the data is 15.
