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

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

$\sigma ^2 =25$

A line with slope -2/3 passes through the point (-12,16) What is the X-intercept

Troyanec [42]

to find the x-intercept of a function, we simply set y = 0 and then solve for "x", so, let's first find the equation of it and then set y = 0.

$\bf (\stackrel{x_1}{-12}~,~\stackrel{y_1}{16})~\hspace{10em} slope = m\implies-\cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-16=-\cfrac{2}{3}[x-(-12)] \\\\\\ y-16=-\cfrac{2}{3}(x+12)\implies \stackrel{\stackrel{y}{\downarrow }}{0}-16=-\cfrac{2}{3}x-8\implies -8=-\cfrac{2x}{3} \\\\\\ -24=-2x\implies \cfrac{-24}{-2}=x\implies 12=x \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill (12,0) ~\hfill$
