d.
9 scoops of red sand for every 6 scoops of blue sand

Option D

ANSWER:  

9 scoops of red sand for every 6 scoops of blue sand maintains the ratio Ross wants.

SOLUTION:

Given, Ross is making colored sand for an art project.  

He mixes 3 scoops of red sand for every 2 scoops of blue sand.

First, let us calculate the ratio of given information.

ratio of red sand to blue sand = 3 : 2

Now, let us check the options.

A. 12 scoops of red sand for every 9 scoops of blue sand

Here, ratio of red sand to blue sand = 12 : 9 = 4 : 3

This ratio does not matches with our ratio. So this is not correct option.

B. 10 scoops of red sand for every 8 scoops of blue sand  

Here, ratio of red sand to blue sand = 10 : 8 = 5 : 4

This ratio does not matches with our ratio. So this is not correct option

C. 8 scoops of red sand for every 12 scoops of blue sand  

Here, ratio of red sand to blue sand = 8 : 12 = 2 : 3

This ratio does not matches with our ratio. So this is not correct option

D. 9 scoops of red sand for every 6 scoops of blue sand

Here, ratio of red sand to blue sand = 9 : 6 = 3 : 2

This ratio matches with our ratio. So this is correct option.

Hence, correct option is D.

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
