Nick surveyed a random sample of the freshman class of his high school to determine whether spring break should be in March or April 1990 students surveyed 26.6% preferred April. Based on this information about how many students and then to hire 230 person class would be expected to prefer having spring break in March?

91

Step-by-step explanation:  33.2 percent of a 275 person class is 91.3, and yoy round down because you can't have 0.3 of a person

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

the answer is d. 75%
