Answer:

a) The marginal cost function is given by

C'(x) = 4 + 0.04x + 0.0003x² (in dollars)

b) C'(70) = $8.27

Step-by-step explanation:

C(x) = 1000 + 4x + 0.02x² + 0.0001x³

a) Marginal cost is usually defined as the cost of producing one extra unit of product. It expresses how much the total cost is changing with respect to number of units of product.

Mathematically,

MC = (dC/dx) = C'(x)

For this question,

C'(x) = 4 + 0.04x + 0.0003x²

b) C'(70) means the marginal cost at x = 70 units, that is, how much the total cost is changing after the production of 70 units; the cost of producing one extra unit of product after producing 70 units.

C'(x) = 4 + 0.04x + 0.0003x²

C'(70) = 4 + 0.04(70) + 0.0003(70²)

C'(70) = $8.27

Answer:

1968.880502

Step-by-step explanation:

The average rate of change of f over intervals of x from x = 3 to  = 3.5 is - 159.

Given that the function is,

f (x) = - 5x³

Used the formula for the average rate of change of function f at interval [a, b] is,

f' (x) = [ f (b) - f (a) ] / (b - a)

Here, f (x) = - 5x³

At x = 3;

f (3) = - 5 × 3³

= - 135

At x = 3.5;

f (3.5) = - 5 × (3.5)³

= - 214.4

Hence, the average rate of change of f over intervals of x from x = 3 to  = 3.5 is,

f ' (x) = [- 214.5 - (- 135)] / (3.5 - 3)

f ' (x) = [- 79.5] / 0.5

f ' (x) = - 159

Final answer:

The average rate of change of the function f(x) = -5[tex]x^3[/tex] from x = 3 to x = 3.5 is -158.75.

Explanation:

The average rate of change (ARoC) can be determined using the formula:

ARoC = (f(x2) - f(x1)) / (x2 - x1)

In this case, the given function is f(x) = -5x^3. To find the ARoC from x = 3 to x = 3.5, substitute these values into the formula:

ARoC = (-5[tex](3.5)^3 - (-5(3)^3)[/tex]) / (3.5 - 3)

Simplifying the equation gives:

ARoC = (-5(42.875) - (-5(27))) / (0.5)

ARoC = (-214.375 + 135) / 0.5

ARoC = -79.375 / 0.5

ARoC = -158.75

Therefore, the average rate of change of f(x) from x = 3 to x = 3.5 is -158.75.

Answer:

The answers to the question are;

(a) 0.042 to three decimal places.

(b) 0.115 to three decimal places.

(c) μ = 8.25, σ = 1.44 to two decimal places.

Step-by-step explanation:

To solve the question, we note that this is a binomial distribution problem

(a) The probability that all 11 will be available is given by

P(11) = ₁₁C₁₁ × 0.75¹¹×0.25¹¹⁻¹¹ = 0.0422

(b) Probability of 6 or less success = P(6) + P(5) +P(4) +P(3) + P(2) + P(1) +P(0)

P(6)  = ₁₁C₆ × 0.75⁶×0.25⁵ = 0.080299

P(5) = ₁₁C₅ × 0.75⁵×0.25⁶ = 0.026766

P(4) = ₁₁C₄ × 0.75⁴×0.25⁷ = 0.063729

P(3) = ₁₁C₃ × 0.75³×0.25⁸ = 0.001062

P(2) = ₁₁C₂ × 0.75²×0.25⁹ = 0.0001180

P(1) = ₁₁C₁ × 0.75¹×0.25¹⁰ = 0.000007867

P(0) = ₁₁C₀ × 0.75⁰×0.25¹¹ = 0.00000002384

Therefore P(6) + P(5) +P(4) +P(3) + P(2) + P(1) +P(0) = 0.11462

Which is 0.115 to three decimal places

(c) The expected number of those available to serve on the jury =

Probability of success = n·p = 11×0.75 = 8.25

μ = 8.25

The standard deviation,σ [tex]=\sqrt{npq}[/tex] =[tex]\sqrt{11*0.75*0.25}[/tex] = 1.43614 ≅ 1.44 to two decimal places

The probability of everyone being available for jury duty can be calculated by multiplying the individual probabilities. More complex probabilities, such as the chance of more than 5 not being available, can be determined using a binomial distribution or a normal approximation. The expected number and standard deviation are calculated from these probabilities.

The probability of different outcomes for jury duty service can be calculated based on known probabilities and using principles of statistics. If 25% of those called find an excuse to avoid it, that means 75% are available. We can use that data to find the probability of all 11 individuals being available, or more than 5 being unavailable.

a) Probability that all 11 will be available: The probability would be (0.75)^11 = 0.042. Because all events are independent, we multiply the individual probabilities.

b) Probability that 5 or more will not be available: You would use a binomial distribution or a normal approximation to a binomial distribution to find this probability (0.115).

c) Expected number and standard deviation: The expected number of people available to serve would be the total people called multiplied by the probability of being available (11*0.75) = 8.25 people. The standard deviation, which is a bit more complex to compute, would be about 1.436 people.

m∠3 = ?

Process

1.- If lines l and m are parallel then angles 1 and 3 are interior alternate angles.

2.- Interior alternate angle measure the same.

3.-  m∠1 = m∠3

4.- m∠3 = 34°

5.- Another information given is not necessary to answer this question.

Answer: 34°

Step-by-step explanation:

There may be another way to do it; angle 1 is equal to 34°, angle one and the supplement of 3(we will call it angle 4) are supplementary. So if angle 1 equals 34, angle 4 = 180-34 (which equals 146). since angles 3 and 4 are supplementary, angle 3; would equal 180 - 146 (which equals 34).

Final answer:

The trigonometric functions and their inverse functions are related to each other because they undo each other's actions. Inverse trigonometric functions give the angle whose trigonometric ratio is a given value. The domains and ranges of inverse trigonometric functions are restricted to ensure that they are well-defined.

Explanation:

The trigonometric functions and their inverse functions are related to each other because they undo the actions of the other function. Let's take the sine function as an example. The sine function takes an angle as input and gives the ratio of the opposite side to the hypotenuse as output. Its inverse function, arcsine, takes a ratio as input and gives the angle whose sine is that ratio as output.

These comparisons make sense in the light of the definition of the inverse of a function because an inverse function undoes the action of the original function. In the case of trigonometric functions, they represent a ratio between the sides of a right-angled triangle, and their inverses give the corresponding angle.

The domains and ranges of the inverse trigonometric functions make sense in relation to their parent functions because they are restricted to a specific range to ensure that the inverse function is well-defined. For example, the domain of arcsine function is [-1, 1] because the output of sine function is always between -1 and 1. By restricting the domain, we can ensure that the inverse function is a one-to-one mapping and has a well-defined output for each input.

Answer: the total area where roses will be planted is 1520 feet²

Step-by-step explanation:

The formula for determining the area of a parallelogram is expressed as

Area = base × height

From the information given,

Base = 20 + 40 = 60 feet

Height = 38 feet

Area of the rose garden = 60 × 38 = 2280 feet²

The formula for determining the area of a rectangle is expressed as

Area = length × width

From the information given,

Length = 38 feet

Width = 20 feet

Area of the rectangular walkway is

20 × 38 = 760 feet²

Therefore, the total area where roses will be planted is

2280 - 760 = 1520 feet²

Answer: the probability that exactly 2 buyers would prefer red is 0.0320

Step-by-step explanation:

We would assume a binomial distribution for the color preferences of new car buyers. The formula is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = (1 - r) represents the probability of failure.

n represents the number of trials or sample.

From the information given,

p = 40% = 40/100 = 0.4

q = 1 - p = 1 - 0.4

q = 0.6

n = 14

x = r = 2

Therefore,

P(x = 2) = 14C2 × 0.4^2 × 0.6^(14 - 2)

P(x = 2) = 91 × 0.16 × 0.0022

P(x = 2) = 0.0320

  y = 4x -3

Step-by-step explanation:

The line perpendicular to the given line can be written as the same equation with the coefficients of x and y swapped, and one of them negated. The constant may be different, so we'll call it "c".

  4x -y +c = 0 . . . . . line perpendicular to that given

The y-intercept of the second given line can be found by setting x=0. That gives the equation -y -3 = 0. The perpendicular line with x=0 would have equation ...

  -y +c = 0

Comparing these two tells us c = -3.

So, the general form of the perpendicular line we want is ...

  4x -y - 3 = 0

We can add y to put this in slope-intercept form:

  y = 4x -3

The probability that both of the interviewed students are from Middle Georgia State College is 2/7 or 0.2857 rounded to four decimal places.

To calculate the probability that both interviewed students are from Middle Georgia State College, one would use the formula for conditional probability, considering the process as two sequential events. The first student being from the college and then the second one, given the first is already from the college. Since there are four students from the college out of a total of seven, the probability of picking one Middle Georgia State College student first is 4/7. After the first student from the college has been picked, there are now three remaining Middle Georgia students out of the remaining six students. Thus, the probability for the second pick is 3/6, which simplifies to 1/2. The total probability is the product of these two probabilities: (4/7) * (1/2) = 2/7, or approximately 0.2857 when rounded to four decimal places.

Side lengths of cube = [tex]\frac{1}{4} \ foot[/tex]

The part of the truck that is being filled is in the shape of a rectangular prism with dimensions of 8 ft x 6 1/4 ft x 7 1/2 ft.

Question asked:

What is the greatest number of packages that can fit in the truck?

Solution:

First of all we will find volume of cube, then volume of rectangular prism and then simply divide the volume of prism by volume of cube to find the greatest number of packages that can fit in the truck.

[tex]Volume\ of\ cube =a^{3}[/tex]

                          [tex]=\frac{1}{4} \times\frac{1}{4}\times \frac{1}{4} =\frac{1}{64} \ cubic \ foot[/tex]

Length = 8 foot, Breadth = [tex]6\frac{1}{4} =\frac{25}{4} \ foot[/tex], Height =[tex]7\frac{1}{2} =\frac{15}{2} \ foot[/tex]

[tex]Volume\ of\ rectangular\ prism =length\times breadth\times height[/tex]

                                                [tex]=8\times\frac{25}{4} \times\frac{15}{2} \\=\frac{3000}{8} =375\ cubic\ foot[/tex]

The greatest number of packages that can fit in the truck = Volume of prism divided by volume of cube

The greatest number of packages that can fit in the truck = [tex]\frac{375}{\frac{1}{64} } =375\times64=24000\ pieces\ of\ cube[/tex]

Thus, the greatest number of packages that can fit in the truck is 24000 pieces.
