Answer:
a. 4P4 = 24
b. 10P2 = 90
c. 5P1 = 5
Step-by-step explanation:
permutation is the act of arranging the members of a set into a sequence or order( in permutation order is important)
Given a permutation nPr
nPr = n!/(n-r)!
Substituting for each of the cases below we have;
a)4P4 = 4!/(4-4)! = 4! = 24
b) 10P2 = 10!/(10-2)! = 10!/8! = 10×9 = 90
c) 5P1 = 5!/(5-1)! = 5!/4! = 5

<h2>The Mean Absolute Vale (MAD) is 4.4</h2>
Step-by-step explanation:
The mean absolute deviation is defined as
Where is the mean and is the total number of data.
The means is defined as
And,
Replacing these values, in the MAD formula, we have
Therefore, the Mean Absolute Vale (MAD) is 4.4
