With Combination, There are the 98280 ways by which we place books on the shelf.
According to the statement
We have to find that the number of ways can by which place books on the shelf.
So, For this purpose, we know that the
A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
From the given information:
The library has 28 science fiction books. Each shelf holds 5 books
Then
apply the combination,
Then
C(n,r) = C(28,5)
after solving it become
C(28,5) = 28! /(5!(28-5)!)
And
C(28,5) = 28! /(5!(23)!)
Then after rearranging the terms and solving the value becomes
C(28,5) = 98280.
So, With Combination, There are the 98280 ways by which we place books on the shelf.

Answer:
6.5
Step-by-step explanation:
The solution to this systems of linear equations is (0,2). The two lines that are graphed for you intersect at a point. That is the solution. When you are looking to find a coordinate pair given a point, remember that you have to crawl before you walk. Start at the origin. Look to the left or right. If there is not point there, then your x coordinate is zero. Then, look up or down. In this case, the y coordinate is two because you have to go up two units on the y axis to get to the point.
Y=125000 so multiply 0.25 by 125000 =31250 so the total number of votes maya received was 31250
