Answer:

B, Work with the math instructors to create a list of students currently taking a math class. Randomly select

Step-by-step explanation:

Let's think of each scenario at a time.

(A) We select 100 students enrolled in college randomly that should be fine because we are taking only students that can take classes. this rules out faculty members and any other persons but also there may be students that will never take any math course as part of their study plan, this is ruled out on that basis.

(B)if we take 100 students from the list of math instructor, that will ensure that we have taken students that are taking math class now, and math is part of their study plan, seems fine.

(C) visiting cafeteria randomly on multiple days will give us random persons that may not even be enrolled in university. this can be ruled out on that basis.

(D)Ten class at random and surveying each student in every class will make sampling size large or small depending on students enrolled in each of the class this will not give us reliable results.

We can conclude that (B) is the beast method for obtaining reliable results.

How to graph 3y=-x-3
saw5 [17]
So you’ll have to isolate the y by dividing the other side of the equation by 3

3y=-x-3
y=-1/3x-1

-1 will be your y intercept and the slope will be -1/3

you’ll start your line by plotting (0,-1)
then from that point you’ll count down one, right 3
or up one, left 3

hope this helps (:
