Stacy rolls a pair of six-sided fair dice.

insens350 [35]

Answer:

Pr(the sum of the numbers rolled is either a multiple of 3 or an even number)= $\frac{2}{3}$

Step-by-step explanation:

Let A be the event "sum of numbers is multiple of 3"

and B be the event "sum is an even number".

As our dice has six sides, so the sample space of two dices will be of 36 ordered pairs.

|sample space | = 36

Out of which 11 pairs have the sum multiple of 3 and 18 pairs having sum even.

So Pr(A)= $\frac{11}{36}$

and Pr(B)= $\frac{18}{36}$

and Pr(A∩B) = $\frac{5}{36}$ , as 5 pairs are common between A and B.

So now Pr(A or B)= Pr(A∪B)

= Pr(A)+Pr(B) - Pr(A∩B)

= $\frac{11}{36}$ + $\frac{18}{36}$ - $\frac{5}{36}$

= $\frac{24}{36}$

= $\frac{2}{3}$

Answer:

To find m ( slope) we'll use the Slope Formula:

$\boxed{\sf{Slope\:(m)}=\cfrac{y_2-y_1}{x_2-x_1}}$

<u>Subtract the numbers:-</u>

$\sf 7. \:m=\cfrac{4-2}{6-5} =\boxed{2}$

_______________

$\sf 8.\: m=\cfrac{-1-3}{2-6} =\boxed{1}$

_______________

$\sf 9.\: m=\cfrac{-4-(-2)}{3-1} =\boxed{-1}$

_______________

$\sf 10.\: m=\cfrac{0-3}{0-(-3)} =\boxed{-1}$

_______________

$\sf 11.\:m=\cfrac{4-2}{3-1} =\boxed{1}$

_______________

$\sf 12.\: m=\cfrac{1-7}{2-5} =\boxed{2}$

_______________

$\sf 13.\:m=\cfrac{11-9}{1-(-4)} =\boxed{\frac{2}{5}}$

_______________

$\sf 14.\:m=\cfrac{2-3}{3-5} =\boxed{\frac{1}{2}}$

_______________

$\sf 15.\: m=\cfrac{11-5}{2-9} =\boxed{-\frac{6}{7}}$

_______________

$\sf 16.\: m=\cfrac{-7-\left(-6\right)}{8-13}=\boxed{\frac{1}{5}}$

_______________

$\sf 17.\: m=\cfrac{4-4}{6-1} =\boxed{0}$

_______________

$\sf 18. \: m=\cfrac{2-(-7)}{5-5}=$

↑ Undefined

The slope of a line that passes through points (-1, -3) and (-2,5) is:

sweet [91]

Answer:

m = -8

Step-by-step explanation:

Use the slope formula: $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{5+3}{-2+1} =\frac{8}{-1} =-8$

m = -8
