Answer:
The average rate of change from 3 to 6 storms = 0.04
Step-by-step explanation:
Let number of Storms = N
And Predicted Gas Price = P
it is required to find the average rate of change from 3 to 6 storms.
At N = 3 ⇒ P = $2.44
At N = 6 ⇒ P = $2.56
So, the average rate of change = 
Arranging of books is an illustration of permutation and combination
There are 24 different possible arrangements she can make
<h3>How to calculate the number of arrangement</h3>
The number of books is given as:
n = 4
Take the factorial of both sides
n! = 4!
Evaluate
n! = 4 * 3 * 2 * 1
n! = 24
Hence, there are 24 different possible arrangements she can make
