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

Answer:
-5 when ...
Step-by-step explanation:
The rules of exponents can help you simplify the given product.
<h3>Rules</h3>
(a/b)^c = (a^c)/(b^c)
(ab)^c = (a^c)(b^c)
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)
<h3>Application</h3>

This expression does not match any of those offered.
When x=-1 and y=5, this becomes ...

Answer:
6x² + 4x + 10
Step-by-step explanation:
(2x - 2)(3x + 5)
2x(3x + 5) - 2(3x + 5)
6x² + 10x - 6x + 10
6x² + 4x + 10 ans.
hope this helps you !
Answer:
Squirrel population is 440 squirrels.
Step-by-step explanation:
It is given that there are 22 squirrels are marked.
Later the company returned and counted a total of 220 squirrels of which are marked were 11.
So, we can set up proportional equation to find the squirrel population.
Let squirrel population is x.
We can set up proportional equation as

Cross multiply
11 x=4840
Divide both sides by 11
x=440
Best estimate is 440.
