3 0

$\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{-3})~\hspace{10em} \stackrel{slope}{m}\implies \cfrac{7}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-3)}=\stackrel{m}{\cfrac{7}{3}}[x-\stackrel{x_1}{(-3)}] \implies y+3=\cfrac{7}{3}(x+3) \\\\\\ y+3=\cfrac{7}{3}x+7\implies y=\cfrac{7}{3}x+4$

Answer:

a. The empirical rule.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

So the correct answer is:

In mathematics, the distance between one point (a) and another point (b), each with coordinates (x,y), can be computed by taking

anygoal [31]

The formula to find the distance between points $P_{1}$ and $x_{2}$ is given as $\sqrt{ ( y_{1}- y_{2}) ^{2}+ ( x_{1}- x_{2}) ^{2} }$ , where

$y_{1}- y_{2}$ is the vertical distance between two points on the y-axis
$x_{1} - x_{2}$ is the horizontal distance between two points on the x-axis
