The box and whisker plot that matches this data set is option B, the second option.

Step-by-step explanation:

Well right away the median of the set is 75. The only one that matches this is option B. Therefore we do not have to look at the LV, HV, LQ, or UQ, we just know it right away.

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
