Mrs. Juarez graded ten English papers and recorded the scores.

92, 95, 100, 62, 88, 90, 100, 96, 89, 98

Which statements are true?

The range of scores is 38.

Without the outlier, the range of scores would be 12.

The outlier impacts the range more than it impacts the interquartile range.

The interquartile range is 9

Without the outlier, the interquartile range would be 9.5.

Step-by-step explanation:

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

to rewrite a literal equation you may need to divide by a number, or by a variable.
