The weather forecast says there is a 75% chance it will rain today. Which spinner could be used to simulate this probability?

1. 2. 3. 4.

None, of them,  but the closest would be 3 and 2

Step-by-step explanation:

None of the spinners represent 75%, but three and two represent 66.667% (2/3)

Hope that helps, and good luck with homework :)

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
