The cost of controlling emissions at a firm rises rapidly as the amount of emissions reduced increases. Here is a possible model
Nadusha1986 [10]

Answer:

\bar C = 4100\,dollars

Step-by-step explanation:

a) The average value of a function is given by the following integral:

\bar C = \frac{\int\limits^{q_{max}}_{0} {4100+90\cdot q^{2}} \, dq }{q_{max}}

\bar C = \frac{1}{q_{max}}\cdot \left(4100\cdot q_{max} + 30\cdot q_{max}^{3} \right)

\bar C = 4100 + 30\cdot q_{max}^{2}

b) The determination of the minimum average daily cost per pound of pollutant is done by the First Derivative Test and the Second Derivative Test, which is:

\bar C' = 60\cdot q_{max}

60\cdot q_{max} = 0

q_{max} = 0

\bar C'' = 60 (absolute minimum).

The level of reduction corresponding to the lowest average daily cost per pound of pollutant is:

\bar C = 4100\,dollars

A family has two children. If B represents a boy and G represents a girl, the set of outcomes for the possible genders of the ch
olga_2 [115]
To determine the probability, the formula is by number of successful outcomes divided by number of possible outcomes. The number of possible outcomes in this problem is 4.

So to compute the probability distribution:

The number of times that 0 G appeared is 0.25 which is represented by BB which is 1/4.
The number of times that 1 G appeared is .5 which is represented by BG and GB which is 2/4.
The number of times that 2 G appeared is .25 which is represented by GG which is 1/4.

The probability distribution will look like this:
X       Px(x)
0         .25
1          .5
2         .25

30. Shelby walks at a constant rate. The equation that represents this
Marysya12 [62]

Answer:

Step-by-step explanation:

In order for 4*t to equal d, the 4 has to represent a rate with respect to time because the multiplication between them will cancel the time unit. We know this because of the formula d = rt with 'r' being rate

a: 4 is the rate at which Shelby walks, 4 miles per hour

b: T is replaced with 32, so the expression tells us the distance Shelby travels in 32 hours at a rate of 4 miles per hour
