Answer:
9!=362880 ways
Step-by-step explanation:
It is given that there are 4 different mathematics books and 5 different science books.
So basically there are 9 different books. So we have 9 choices for the first book, 8 choices for the second book, since we have placed the first one. We have 7 choices for the third book and so on. Therefore, we can arrange 9 different books in,
!9 ways, on solving !9 we get,
So there are 362,880 ways to arrange 9 different books if there are no restrictions.
Answer:
Positive correlation.

Answer:
2 cups of clay
Step-by-step explanation:
Given data
we are given that 6 cups of water for every 12 cups of clay
i.e
12 cups of clay require 6 cups of water
4 cups of clay will require x cups of water
cross multiply
12x= 4*6
12x= 24
divide both sides by 12
x= 24/12
x= 2cups
Hence 4 cups of water will require 2 cups of clay
