The number of arrangements of the books is an illustration of permutation
The books can be arranged in 5040 ways
<h3>How to determine the number of arrangements?</h3>
The given parameters are:
- Total books, n = 10
- Books to arrange, r = 4
The number of arrangements is calculated as:
Ways = nPr
Substitute the given values
Ways = ¹⁰P₄
Apply the permutation formula
Ways = 10!/(10 - 4)!
Evaluate the quotient
Ways = 5040
Hence, the books can be arranged in 5040 ways

Answer:
Sure whats the number
Step-by-step explanation:
The answer is S ( that's what I got when I put it into a graphing calculator)
13) If T(n) = 2n-7, what is the 5th term?
n is the number of the term you are looking for. In this instance, n is equal to 5.
T(5) = 2(5) - 7
T(5) = 10 -7
T(5) = 3
The 5th term is 3.
17) inequality based on the line number.
Since the line does not extend in any direction outward. It means that the range should be within -3 and 3.
Solid circle means that -3 is equivalent to x
hollow ciccle means that 3 is not x.
-3 <u><</u> x < 3
x = any number from -3 upto 2.
Answer:
Option A - Permutation; number of ways = 210
Step-by-step explanation:
Given : At a competition with 7 runners, medals are awarded for first, second, and third places. Each of the 3 medals is different.
To find : How many ways are there to award the medals?
Solution :
There are 7 runners but medals are three.
The first runner up got first medal as one is locked.
The second runner up got second medal as second is locked.
The third runner up got the third medal.
So, There is a permutation.
Number of ways to award the medals is 
We know, 
Substitute the values,
Therefore, Option A is correct.
Permutation; number of ways = 210
