Abby took an 8-question multiple-choice quiz. Suppose that her probability of correctly answering any question is
0.75. What is Abby's probability of correctly answering
exactly 6 questions on the quiz?
O 0.311
0 0.623
O 0.240
0.089

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
