The slope is 20/13. Yes, the slope is steeper because without the lip on the slide you would travel downward faster.
So to find the answer of the area, you have to multiply 7 and 8 which would equal to 56.
The appropriate compatible numbers to use to estimate would be 20(1/2)
estimated product is 10, took the quiz :)
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
