Morgan rolls a number cube, twice. If the number 1 shows up at least once, Morgan wins. Otherwise, Jaclyn wins. How much greater
alukav5142 [94]
I am assuming from the answer choices that you meant Jaclyn's chances of winning.

There are 6 sides of a dice and it's rolled twice.
6×2=12

So while Morgan has a 2/12 chance (simplified that would be 1/6), Jaclyn has a 10/12 chance of winning (simplified that would be 1/3).

Therefore your answer would be A: 1/3

Write an inequality, in slope-intercept form, for the graph below. If necessary,
Rama09 [41]

Given:

The graph of an inequality.

To find:

The inequality in slope intercept form.

Solution:

The slope intercept form is:

y=mx+b

Where, m is slope and b is y-intercept.

From the given graph it is clear that the boundary line passes through the points (-3,0) and (0,-3).

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

y-0=\dfrac{-3-0}{0-(-3)}(x-(-3))

y=\dfrac{-3}{3}(x+3)

y=-1(x+3)

y=-x-3

From the given graph it is clear that the boundary line is a solid line and the shaded region lies above the line, so the sign of inequality must be "≥".

y\geq -x-3

Therefore, the required inequality is y\geq -x-3.
