Answer:
63568 dollars
Step-by-step explanation:
Given that in your computer store you charge $1012 per computer sold. Your costs are given by the equation

where x is the number of computers sold.
Revenue = sales price *no of computers sold
= 1012x
Profit = Revenue - cost
= 
Use derivative test to find maximum profit

Equate I derivative to 0
x= 128
i.e. if 128 computers are manufactured and sold profit wouldbemaximum
Profit maximum=

Answer:

Step-by-step explanation:
We have the cone and the half-sphere.
The formula of a volume of a cone:

r - radius
H - height
We have r = 7cm and H = (22-7)cm=15cm. Substitute:

The formula of a volume of a sphere:

R - radius
Therefore the formula of a volume of a half-sphere:

We have R = 7cm. Substitute:

The volume of the given shape:

Substitute:

Correction:
I think the question should be like that find the approximate value of
P(-0.78 < z < 1.16)?
Now,
the symbol Ф represent the cumulative density.
first find the
Ф(1.16) from the above given table which is equal to 0.8770.
Now,
find the Ф(-0.78) .
in our table we are given the value of Ф(0.78)=0.7823
so as the curve is symmetrical Ф(-0.78)=1-0.7823=0.2177
P(-0.78 < z < 1.16) = Ф(1.16)-Ф(-0.78)
= 0.8770-0.2177
= 0.6593
