Ответ:
7500 sets
Step-by-step explanation:
We are given that
Cost of each TV set=$85
The cost C(in dollars) of manufacturing and selling x Tv sets per week is given by
Set can be produced at most per week=10000
We have to find the number of sets should be made and sold to maximize the weekly profit.
Revenue=85 x
Where x= number of sets selling per set
Profit=Revenue-Cost
Profit=85x-(1500+10x+0.005x^2)[/tex]
Profit=P=
Differentiate w.r.t x
Substitute
Again differentiate w.r.t x
Hence,function is maximize.
Therefore, 7500 sets should be made and sold to maximize the weekly profit.

The chances that it will not rain is:
80%
Step-by-step explanation:
We are given that:
The chances that it will rain tomorrow are 20%.
Let A denote the event that it will rain.
and A' denote the vent that it will not rain.
Let P denote the probability of an event.
We have:
P(A)=0.20
Hence,
P(A')=1-P(A)
P(A')=1-0.20
P(A')=0.80
which in percent is given by:
P(A')=80%
