The profit function, P(x), can be obtained by finding the difference between the revenue function, R(x), and the cost function, C(x). In this case, P(x) = -330[tex]x^3[/tex] + 9,000[tex]x^2[/tex] - 67,000x + 167,000.

The profit function, P(x), can be obtained by finding the difference between the revenue function, R(x), and the cost function, C(x). In this case, we have:

R(x) = 550[tex]x^3[/tex] - 12,000[tex]x^2[/tex] + 83,000x + 7000

C(x) = 880[tex]x^3[/tex] - 21,000[tex]x^2[/tex] + 150,000x - 160,000

To find P(x), we subtract C(x) from R(x):

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

Substituting the given functions, we get:

P(x) = (550[tex]x^3[/tex] - 12,000[tex]x^2[/tex] + 83,000x + 7000) - (880x3 - 21,000[tex]x^2[/tex] + 150,000x - 160,000)

Simplifying, we combine like terms:

P(x) = -330[tex]x^3[/tex] + 9,000[tex]x^2[/tex] - 67,000x + 167,000

Therefore, the profit function, P(x), can be expressed as a polynomial in standard form as -330[tex]x^3[/tex] + 9,000[tex]x^2[/tex] - 67,000x + 167,000.

The profit function, P(x), is found by subtracting the cost function, C(x), from the revenue function, R(x). After performing the subtraction and simplifying, the profit function in standard form is P(x) = [tex]-330x^3 + 9,000x^2 - 67,000x + 167,000.[/tex]

To find the profit function, P(x), we must subtract the cost function, C(x), from the revenue function, R(x). Given the functions:

R(x) = [tex]550x^3 - 12,000x^2 + 83,000x + 7,000[/tex]

C(x) =[tex]880x^3 - 21,000x^2 + 150,000x - 160,000[/tex]

We perform the subtraction:

P(x) = [tex](550x^3 - 12,000x^2 + 83,000x + 7,000) - (880x^3 - 21,000x^2 + 150,000x - 160,000)[/tex]

Expand and group terms:

P(x) =[tex]550x^3 - 12,000x^2 + 83,000x + 7,000 - 880x^3 + 21,000x^2 - 150,000x + 160,000[/tex]

P(x) = [tex](550x^3 - 880x^3) + (-12,000x^2 + 21,000x^2) + (83,000x - 150,000x) + (7,000 + 160,000)[/tex]

Simplify the terms:

P(x) = [tex]-330x^3 + 9,000x^2 - 67,000x + 167,000[/tex]

The profit function, P(x), in standard form is:

P(x) = [tex]-330x^3 + 9,000x^2 - 67,000x + 167,000[/tex]

Answer:

[tex]200+48n\leq 3500[/tex]

[tex]n\leq 66.7[/tex]

Step-by-step explanation:

Let the number of cartons he can safely put on the elevator at one time=n

Total weight of Carton=48n

Since the weight of the man and the cartons combined must not be more than 3500 pounds,

Therefore,an inequality that represents the situation is:

[tex]200+48n\leq 3500[/tex]

We can solve for n if required

[tex]200-200+48n\leq 3500-200\\48n\leq 3200\\\text{Divide both sides by 48}\\n\leq66.7[/tex]

The delivery man can safely carry 66 Cartons.

Given:

The system of equation:

[tex]x+y = -4[/tex] -------- (1)

[tex]y = x^{2} -6x[/tex] --------- (2)

To find the values of x and y.

We will use substitution method.

From (1) we get,

[tex]y = -4-x[/tex]

We will put the value of y in (1) and we get,

[tex]-x-4 = x^{2} -6x[/tex]

or, [tex]x^{2} -5x+4= 0[/tex]

Now we will apply middle term factor method.

  [tex]x^{2} -(4+1)x+4 = 0[/tex]

     [tex]x^{2} -4x-x +4 = 0[/tex]

[tex]x(x-4)-1(x-4) = 0[/tex]

       [tex](x-4)(x-1)= 0[/tex]

so, x = 4 and 1

Now,

Substitute x = 4 in (1) we get,

[tex]y = -4-4 = -8[/tex]

And putting x = 1 in (1) we get,

[tex]y = -4-1 = -5[/tex]

Hence, the solution of the given system of equation is (4,-8) and (1,-5)

Thus, Option A is the correct answer.

For on it depends on how many cards you have and how many 4's there are

Step-by-step explanation:

So say you had 16 cards and 3 of them were 4 the probability of you picking a 4 is 3 of 16.

Final answer:

The probability of drawing a 4 and then another 4 in sequence without replacement from a 52-card deck is 1/221, calculated by multiplying the probabilities of drawing a four on the first and second draws, 1/13 and 1/17, respective

Explanation:

The question involves calculating the probability of drawing two specific cards in sequence without replacement from a standard deck of 52 cards. The condition provided is drawing a 4 first and then drawing another 4 without putting the first card back. To solve this, consider the probability of each event happening.

For the first draw, there are 4 fours in a deck of 52 cards, so the probability of drawing a four (P(A)) is 4/52 or 1/13.

After drawing one four and not returning it, there are now 51 cards left and only 3 fours left. Therefore, the probability of drawing a four as the second card (P(B) given A) is 3/51 or 1/17.

To find the total probability of both events happening in sequence, multiply the probabilities of the individual events: 1/13 * 1/17.

Thus, the probability of drawing a 4 and then another 4 in sequence without replacement is 1/221.

Step-by-step explanation:

10 x 25 is 250, 20 x 10 is 200 and 250 + 200 is 450

The scarf is $20 without tax.

The scarf is 20% off of 25, 5 is 20% of 25 so all you have to do is 25 - 5 to get your answer.

25 - 5 = 20

The sale price of the scarf , not including the tax is $20.00.

A sale price is the discounted price at which goods or services are being sold.

sale price = original price - discount price

According to the given question,

the original price of the scarf is $25.00

discount price = 20%of original price

⇒ discount price =[tex]\frac{20}{100}[/tex]×[tex]25[/tex]

⇒discount price = $5.00

Therefore,

Answer:

The amount made in a month with 9 sales people = 334,734.53

Step-by-step explanation:

The amount, Y, made by a sales company in dollars is related to the number of sales people, x, at the company through the relation,

Y = 60,209.47x - 207,150.70

where Y = amount made in dollars

x = number of sales people

when x = 9, what is Y.

Y = 60,209.47x - 207,150.70

Y = (60,209.47×9) - 207,150.70

Y = 541,885.23 - 207,150.70

Y = 334,734.53

Answer:

B

Step-by-step explanation:

Compare triangle ABC with triangle A'B'C. Let's try to prove that they're similar.

BC = 6 + 3 = 9 units

B'C = 6 units

BC/B'C' = 9/6 = 3/2 = 1.5

AC = 2 + 4 = 6 units

A'C = 4 units

AC/A'C = 6/4 = 3/2 = 1.5

These two pairs of corresponding sides have the same ratio, so that's promising.

Also notice that angle BCA = angle B'CA'. So, by SAS Similarity Theorem, we know that triangles ABC and A'B'C are similar.

By definition, similar triangles have the same corresponding angles.

Angle ABC corresponds to angle A'B'C, so they're equal. Since angle ABC = 40 degrees, then angle A'B'C = 40 degrees, as well.

Hope this helps!

Without proper context or a diagram, it's impossible to definitively state the measure of angle A'B'C. However, as an example, if angle A'B'C is in an equilateral triangle, it would be 60 degrees.

The question appears to be asking about the measure of an angle, designated as A'B'C. However, without proper context or a diagram to reference, it's impossible to definitively state what the measure of angle A'B'C is. It can be any value depending on the context. But, if A'B'C is a part of a triangle or a particular geometric shape with known properties, we can solve it based on the information given related to that specific shape.

For example, in an equilateral triangle, each angle measures 60°. So, if A'B'C is an angle in an equilateral triangle, it would most likely be 60°. Yet, without sufficient context, this is simply a hypothetical situation.

The probabilities of interest when rolling a pair of fair six-sided dice are: P(A) the probability of the first die being a 5 is 1/6, P(B) the probability of the second die being a 3 is 1/6, P(A and B) the probability of both events occurring is 1/36, and P(B|A) the conditional probability of B given A is equal to P(B), indicating that events A and B are independent.

When rolling a pair of fair six-sided dice, each die is independent of the other. Therefore, the sample space consists of 6 x 6 = 36 equally likely outcomes. The probability that the first die is a 5, event A, is P(A) = 1/6 because there are 6 possible outcomes for the first die and only one of them is a 5.

The probability that the second die is a 3, event B, is also P(B) = 1/6 for the same reason as A, as there are 6 possible outcomes and only one of them is a 3. Now, the probability that the first die is a 5 and the second die is a 3, both events occurring simultaneously (A and B), is P(A and B) = P(A) times P(B) which equals 1/36.

The conditional probability that the second die is a 3 given that the first die is a 5, P(B|A), is simply the probability of B since events A and B are independent, so P(B|A) = P(B) = 1/6. This implies that knowing the outcome of the first die does not change the probability of the second die rolling a 3.

Given this independence, P(B|A) = P(B), and thus events A and B are indeed independent events.

[tex](a) \( P(A) = \frac{1}{6} \)\\(b) \( P(B) = \frac{1}{6} \)\\(c) \( P(A \text{ and } B) = \frac{1}{36} \)\\(d) \( P(B|A) = \frac{1}{6} \)\\(e) No, \( P(B|A) \neq P(B) \); events A and B are dependent.[/tex]

(a) P(A), the probability that the first die is a 5:

There are 6 outcomes where the first die is a 5.

[tex]\[ P(A) = \frac{\text{Number of outcomes where first die is a 5}}{\text{Total number of outcomes}} = \frac{6}{36} = \frac{1}{6} \][/tex]

(b) P(B), the probability that the second die is a 3:

There are 6 outcomes where the second die is a 3.

[tex]\[ P(B) = \frac{\text{Number of outcomes where second die is a 3}}{\text{Total number of outcomes}} = \frac{6}{36} = \frac{1}{6} \](c) \( P(A \text{ and } B) \), the probability that the first die is a 5 and the second die is a 3:[/tex]

There is only 1 outcome where the first die is a 5 and the second die is a 3, which is (5,3).

[tex]\[ P(A \text{ and } B) = \frac{\text{Number of outcomes where both A and B occur}}{\text{Total number of outcomes}} = \frac{1}{36} \][/tex]

(d) P(B|A)  the conditional probability that the second die is a 3 given that the first die is a 5:

Given that the first die is a 5, there are 6 possible outcomes for the second die, and 1 of those outcomes is a 3 (the outcome (5,3)).

[tex]\[ P(B|A) = \frac{\text{Number of outcomes where B occurs given A}}{\text{Number of outcomes where A occurs}} = \frac{1}{6} \][/tex]

(e) [tex]\[ P(B|A) = \frac{1}{6} \neq \frac{1}{6} = P(B) \]\\Since \( P(B|A) \neq P(B) \), the events A and B are dependent, not independent.[/tex]

Answer:

you would have 80 units of space

Step-by-step explanation:

to find out how much volume there is you have to multiply the base x the width x the height so that would be 8x5x2 and 8x5 is 40 and 40x2 is 80

The box has a volume of 80 cubic inches, determined by multiplying its dimensions: length (8 inches), width (5 inches), and height (2 inches).

To determine the space available for candy in the given box, we need to calculate the volume of the box. The volume of a rectangular box can be found by multiplying its length, width, and height. Here, the box measures 8 inches in length, 5 inches in width, and 2 inches in height.

To find the volume, use the formula:

Volume = Length × Width × Height

In this case, the volume is:

Volume = 8 inches × 5 inches × 2 inches = 80 cubic inches

Therefore, the box has 80 cubic inches of space available for candy.

Answer: the minimum score required for the scholarship is 29.24

Step-by-step explanation:

Since the scores are normally distributed, it follows the central limit theorem. The formula for determining the z score is

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = population standard deviation

Since the university plans to award scholarships to students whose scores are in the top 9%, the scores that would be qualified are scores which are at least 91%(100 - 9 = 91).

Looking at the normal distribution table, the z score corresponding to the probability value of 0.91(91/100) is 1.35

From the information given,

µ = 21

σ = 6.1

Therefore,

1.35 = (x - 21)/6.1

6.1 × 1.35 = x - 21

8.235 = x - 21

x = 8.235 + 21 = 29.24

The minimum ACT Reading score required to be in the top 9% for a university scholarship is approximately 29.2, determined by using a z-score of 1.34, the mean score of 21, and the standard deviation of 6.1.

To determine the minimum ACT Reading score required to be in the top 9% of students, and hence eligible for a scholarship at a university, we utilize the concept of z-scores in a normal distribution. A z-score indicates how many standard deviations an element is from the mean.

First, we need to find the z-score that corresponds to the top 9% of the distribution. Standard z-score tables or calculators will show that the z-score for the top 9% is approximately 1.34. This z-score means the score is 1.34 standard deviations above the mean. Next, we apply the z-score formula:

Z = (X - μ) / σ

Where:
Z is the z-score (1.34 in this case),
X is the ACT score we want to find,
μ is the mean (21 for ACT Reading),
σ is the standard deviation (6.1 for ACT Reading).

We can rearrange the formula to solve for X (the ACT score):
X = Z * σ + μ

Substituting the values we have:

X = 1.34 * 6.1 + 21

X ≈ 29.214

The minimum ACT Reading score required for the scholarship is therefore approximately 29.2 when rounded to the nearest tenth.

As she practice for two weeks, three days of each week:

On two Monday, she will practice = [tex]\frac{3}{2} + \frac{3}{2} =\frac{3+3}{2} =\frac{6}{2} =3\ hours[/tex]

On two Tuesday, she will practice = [tex]\frac{7}{4} +\frac{7}{4}=\frac{7+7}{4} =\frac{14}{4} =\frac{7}{2} \ hours[/tex]

On two Wednesday, she will practice = [tex]2+2=4 \ hours[/tex]

Total hours, she will practice over 6 days  [tex]=3+\frac{7}{2} +4[/tex]

                                                                      [tex]=7+\frac{7}{2} \\ \\ =\frac{2\times7+7}{2} \\ \\ =\frac{21}{2} \\ \\ =10.5\ hours[/tex]

Thus, Andres will practice 10.5 hours with his band over these 6 days.

The total number of hours andres will practice with his band over these 6 days is 10 1/2 hours

Given:

Day 1 = 1 1/2 hours

Day 2 = 1 3/4 hours

Day 3 = 2 hours

The total number of hours for six days = 2(1 1/2) + 2(1 3/4) + 2(2)

= 2(3/2) + 2(7/4) + 4

= 6/2 + 14/4 + 4

= 3 + 14/4 + 4

= 7 + 14/4

= (28+14) / 4

= 42 / 4

= 10 2/4

= 10 1/2 hours

Therefore, the total number of hours andres will practice with his band over these 6 days is 10 1/2 hours
