The total cost (in dollars) for a company to manufacture and sell x items per week is C(x)=50x+400. If the revenue brought in by

Vedmedyk [2.9K]

Answer:

$720

Step-by-step explanation:

Given the following functions

Cost function C(x)=50x+400

Revenue function R(x)=80x-0.05x^2

P(x)=R(x)−C(x).

Profit function P(x) = 80x-0.05x^2 - (50x+400)

P(x) = 80x-0.05x^2 - 50x - 400

Substitute x = 40

P(40) = 80(40)-0.05(40)^2 - 50(40) - 400

P(40) = 3200-80-2000-400

P(40) =3200-2480

P(40) = 720

Hence the amount of profit made is $720

the number one bees that visit a plant is 500 times the number of years the plant is alive where T represents the number of year

ira [324]

500t represents the number of times bees visit the flower because if bees visit the flower 500 times for every year it is alive, and it was alive 5 years, then it would be 500 times 5. So 500t represents how to find how many times a bee would visit a particular plant.

Please help me it says find the measure of c and b and I don’t know how if you can help me with this exam it would be much appre

noname [10]

Answer:

b=20

C=160

Step-by-step explanation:

160+b= 180 (sum of angle on the straight line)

b=180-160

b=20

b+c =180 (sum of angle on the straight line)

20+c=180

c=180-20

C=160

Assume that different groups of couples use the XSORT method of gender selection and each couple gives birth to one baby. The XS

olganol [36]

Answer:

Mean and Standard deviation for the numbers of girls in groups of 36 births are 18 and 3 respectively.

Step-by-step explanation:

We are given that he X SORT method is designed to increase the likelihood that a baby will be a girl, but assume that the method has no effect, so the probability of a girl is 0.5.

Now consider a group consisting of 36 couples.

The above situation can be represented through binomial distribution;

$P(X=r)=\binom{n}{r} \times p^{r} \times (1-p)^{n-r} ;x=0,1,2,3,.....$
