7. The double dot plot shows the weights in pounds of several housecats and small dogs. Which inference can be made based on the information given below? A. Small dogs median is larger than housecats.

B. Overall, house cats weigh more with less variation.

C. Overall, small dogs weigh more with less variation

D. Small dogs and housecats have the same median.

B.

Step-by-step explanation:

For reference, the median for housecats is 11 and the median for small dogs is 9. So, by process of elimination, B is the correct answer.

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
