The value of the ___________ is used to estimate the value of the population parameter.

Nat2105 [25]

Answer:

The total profit P(x) or the month is $P(x)=-0.5x^2+500x-350$ .

Step-by-step explanation:

A company produces x units of a product per month.

The total cost represents by the function C(x).

$C(x)=300x+250$

The total revenue represents by the function R(x).

$R(x)=-0.5x^2+800x-100$

The profit is the difference between revenue and cost.

$P(x)=R(x)-C(x)$

$P(x)=-0.5x^2+800x-100-(300x+250)$

$P(x)=-0.5x^2+800x-100-300x-250$

Combine like terms.

$P(x)=-0.5x^2+(800x-300x)+(-100-250)$

$P(x)=-0.5x^2+500x-350$

Therefore, the total profit P(x) or the month is $P(x)=-0.5x^2+500x-350$ .

jolli1 [7]

Answer:

Part 1) $x-2y=2$ ----> (2,0) and (0,-1)

Part 2) $-3x+3y=7$ ----> (-7/3,0) and (0,7/3)

Part 3) $7x-y=21$ ----> (3,0) and (0,-21)

Part 4) $3x-5y=-20$ ----> (-20/3,0) and (0,4)

Step-by-step explanation:

we know that

The y-intercept is the value of y when the value of x is equal to zero

The x-intercept is the value of x when the value of y is equal to zero

Part 1) we have

$x-2y=2$

1) Find the x-intercept

For y=0

$x-2(0)=2\\x=2$

the x-intercept is (2,0)

2) Find the y-intercept

For x=0

$0-2y=2\\y=-1$

the y-intercept is (0,-1)

Part 2) we have

$-3x+3y=7$

1) Find the x-intercept

For y=0

$-3x+3(0)=7\\x=-\frac{7}{3}$

the x-intercept is (-7/3,0)

2) Find the y-intercept

For x=0

$-3(0)+3y=7\\y=\frac{7}{3}$

the y-intercept is (0,7/3)

Part 3) we have

$7x-y=21$

1) Find the x-intercept

For y=0

$7x-(0)=21\\x=3$

the x-intercept is (3,0)

2) Find the y-intercept

For x=0

$7(0)-y=21\\y=-21$

the y-intercept is (0,-21)

Part 4) we have

$3x-5y=-20$

1) Find the x-intercept

For y=0

$3x-5(0)=-20\\x=-\frac{20}{3}$

the x-intercept is (-20/3,0)

2) Find the y-intercept

For x=0

$3(0)-5y=-20\\y=4$

the y-intercept is (0,4)

The campus bookstore knows from the past several semesters that a certain elementary statistics book has a demand that is approx

Likurg_2 [28]

Answer:

$117

Step-by-step explanation:

Given that:

They buy these books for $105 each and sell them to unsuspecting undergraduates at $222 each

Marginal Profit = Marginal Revenue – Marginal Cost.

Marginal Profit = $222 - $105

Marginal Profit = $117

the marginal profit for a single elementary statistics book $117

For the remaining unsold books in the middle of the semester he bundles them up and sells to vendor in another country for $40 each for which he suffers a marginal loss of $105 - $40 = $65 each

san4es73 [151]

Answer: A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.

Step-by-step explanation:

Here are the options:

A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.

B) A boy is 33% more likely than a girl to own a dog than a cat or other animal.

C) A boy is 50% more likely than a girl to own a dog than a cat or other animal.

D) A boy is 52% more likely than a girl to own a dog than a cat or other animal.

Boy with a dog = 27

Total animals owned by boys = 27+15+10 = 52

Probability of owning a dog = 27/52 = 0.5192

Girl with dogs = 18

Total animals owned by girls = 18+25+12 = 55

Probability of owning a dog = 18/55 = 0.3273

Therefore, 0.5192 - 0.3273 = 0.1919 = 19.19%

Therefore, A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
