Answer:

A. y = -8x + 80

Explanation:

Take two points from the best fit line (2, 64), (6, 32)

<h3>Find the slope:</h3>

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

$\sf \rightarrow slope \ (m) : \dfrac{32-64}{6-2} = -8$

<h3>Find the equation:</h3>

$\sf y - y_1 =m(x - x_1 )$

$\sf \rightarrow y- 64 = -8(x - 2)$

$\sf \rightarrow y = -8x + 16 + 64$

$\sf \rightarrow y = -8x +80$

Answer:

Step-by-step explanation:

As the sample size n increases, the sample mean (μy) becomes a more accurate estimate of the parametric mean, so the standard error of the mean becomes smaller. Therefore, the variance of y decreases and the distribution of y becomes highly concentrated around μy.

Answer:

$m\angle N=57^{\circ}$

Step-by-step explanation:

From the isosceles-base theorem, the measure of the angles adjacent to the pair of congruent sides of the triangle are equal. Since the problem declares $LM\cong LN$ , the remaining unknown angles are equal ( $m\angle N=m\angle M$ ). The sum of the interior angles of a triangle always add up to $180^{\circ}$$ .
