Answer:
Step-by-step explanation:
Given
Cost Price 
Price 
Revenue generated 
where x=no of units

To get maxima and minima differentiate R(x)




maximum Revenue 
(b)Profit=Revenue - cost



differentiate Profit to get maximum value


maximum Profit 
(c)Now company decided to tax the company $ 55 for each set
Profit 


differentiate Profit to get maximum value




company should charge 207.5 $ for each set

19 birds where there on Friday
X=5. this is true because if y=0 and y=15-3x, then 15-3x=0. if x is 5, it would be 15-3(5)=0.
Triangle base that measures 9 inches, 12 inches, 15 inches and a height of 14 inches.
The number of combinations of size
that you can make with
items is given by the so-called binomial coefficient,

•
is the number of ways of permuting
items.
•
is the number of ways of permuting all but
of the
items.
Dividing
by
then gives the number of ways of permuting only
of the total
items.
•
is the number of ways of permuting
items.
Dividing
by
then removes all those permutations which contain the same items. We call these combinations.
For this problem we only care about counting combinations.
There are

ways of selecting any 3 girls from the total 6 girls in the entire group of people.
There are

was of selecting any 2 boys from the total 7 boys.
Then there are

ways of choosing a committee of 5 people consisting of 3 girls and 2 boys.
If the next question were, "What is the probability that a committee of 5 randomly selected people consists of 3 girls and 2 boys?", then you would additionally need to compute the number of ways one can make a committee of 5 people from the total 13, which is

Then the probability of selecting such a committee at random is
