Ranking is very critical in this problem. Therefore, the most applicable mathematical theory is permutations.
Ranking possible for the cellists:
Needed cellists = 5
Total available cellists = 10
Possible number of rankings = 10P5 = 10!/(10-5)! = 30240
Ranking possible for the violinists:
Needed violinists = 5
Total available = 16
Possible number of rankings = 16P5 = 16!/(16-5)! = 524160
Therefore,
Ratio of rankings (cellists to violinists) = 30240/524160 = 3/52
Answer 2.8

Answer:
186 books with the 55% increase
Step-by-step explanation:

Answer:
The area of the logo is 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The area of a semicircle is equal to
so
The area of the logo is equal to multiply by 3 the area of one semicircle
we have
-----> the radius is half the diameter
substitute
