ANSWER
D. 14
EXPLANATION
The ratio of the books in the book case are:
Red:Yellow:Green=3:5:2
The number of yellow books in the book case is 35.
If 5 corresponds to 35, then 2 green books will correspond to a less number of books,
By proportion, because it is going to be less more will divide.
The number of green books in the book case is
![= \frac{35 \times 2}{5}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B35%20%5Ctimes%202%7D%7B5%7D%20)
![= 7 \times 2 = 14](https://tex.z-dn.net/?f=%20%3D%207%20%5Ctimes%202%20%3D%2014)

Step-by-step explanation:
The answer is A because the median is the middle number (4) in an ascending or descending list of numbers and the mean is 3 because if you take the four numbers above 0 you get the total then divide the total by how many numbers there are you get your mean and 15 divided by 5 is 3. Hopefully this helped if not I can explain a little more if you need it!!
