rewona [7]

Answer:

$\quad y=-\frac{24-3x}{8}$

Step-by-step explanation:

1. Subtract 3x from both sides

3x-8y-3x=24-3x

2. Simplify

-8y=24-3x

3. Divide both sides by -8

$\frac{-8y}{-8}=\frac{24}{-8}-\frac{3x}{-8}$

Calculating the degrees of freedom, the sample variance, and the estimated standard error for evaluations.

ki77a [65]

Answer:

The variance is $\sigma ^2 =25$

Step-by-step explanation:

From the question we are told that

The sample size is n = 21

The sum of squares is $SS = 500$

Generally the variance is mathematically represented as

$\sigma ^2 = \frac{SS}{n- 1}$

substituting values

$\sigma ^2 = \frac{ 500}{21- 1}$

$\sigma ^2 =25$
