What is the probability that a point chosen at random on the grid will lie in the unshaded region?

a. 5/8
b. 3/5
c.2/5
d.3/8

The answer is the d.

Step-by-step explanation:

Hello! Let's solve this!

First we count the amount of squares. In total there are 64.

Then we count the amount of squares painted. In total there are 24.

Then we do the following operation

24/64

Simplifying results in 3/8

The answer is the d.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
