Well, we know the numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11. From these numbers, 6 are odd. So, 6/11 is the probability that it is odd.

The slope of mn is -3<br><br> Which segment are parallel to mn <br><br> Select each correct answer.

Sati [7]

keeping in mind that any line parallel to MN will have the same exact slope as MN's.

$\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{6})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{0}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{0-6}{4-2}\implies \cfrac{-6}{2}\implies \cfrac{-3}{1}\implies -3~~\checkmark \\\\[-0.35em] ~\dotfill$

$\bf (\stackrel{x_1}{8}~,~\stackrel{y_1}{1})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{10}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{10-1}{5-8}\implies \cfrac{9}{-3}\implies \cfrac{3}{-1}\implies -3~~\checkmark$
