The total cost for 10 hours of work would be 25 + 50(10) = 525.

Cost is the monitorial associated with the purchase of production of food or service if can include the prices of material of which is over it and other expenses that are related to the production of the code of service cost is a major fraction of when deciding whether to purchase a product something as it is and indicator of the value of the product of sound service.
The marginal cost of producing 5 items can be calculated using the equation C(x)=1300+4x/10. The marginal cost is the cost associated with producing one additional item. To calculate the marginal cost, we can plug in x=5 into the equation.

The equation in slope-intercept form for cost, c, after h hours of service is c = 25 + 50h.

The total cost for 8 hours of work would be 25 + 50(8) = 425.

The total cost for 10 hours of work would be 25 + 50(10) = 525.

The probability of a majority of the advisory board opposes to funding is 0.352

Two events are said to be independent of each other if the probability that one event occurs in no way affects the probability of the other event occurring .If A and B are independent events then the probability that they all occur is given by P(A) x P(B)

Here, the opinions of the three students on the board are independent the probability is 0.4 that each opposes the funding of interest groups

Mjority of the board opposes can be when two or more members oppose it.

P(ABC) = P(A) x P(B) x P(C)

P(ABC) = 3 (0.6) x 0.4 x 0.4 + 0.4 x 0.4 x 0.4

= 0.288 + 0.064

Answer:

\(f(x)=x^3-7x^2-6x+72\)

Step-by-step explanation:

\(f(x)=a(x-p)(x-q)(x-r)\\\\f(x)=1(x-6)(x+3)(x-4)\\\\f(x)=(x^2-3x-18)(x-4)\\\\f(x)=x^3-4x^2-3x^2+12x-18x+72\\\\f(x)=x^3-7x^2-6x+72\)

By using the given domain and range, we will see that the false statements are:

What we know about the function f(x) is:

The domain is: -10 ≤ x ≤ 20

The range is: -40 ≤ f(x) ≤ -10

Which statements are false:

1)  f(0)= 0

This is false, because the maximum value of the range is -10, so f(0) can't be equal to zero.

2. f(1) = 13

Same reasoning than above, 13 is outside of the range.

3. f(-15) =- 20

The smallest value on the domain (possible inputs) is -10, so the input -15 is not in the domain.

Answer:

The measures of <2 and <8 are 124 degrees

Step-by-step explanation:

<2 is congruent to <4 by the Vertical Angles Theorem, and <4 is congruent to <8 by the corresponding angles theorem. <2 is congruent to <8 by the Transitive Property so we get <2 is congruent to <8, and it follows that m<2 equals m<8 by the definition of congruence. We can substitute <2 and <8 with 11x+3 and 13x-19 respectively, so we get 11x+3=13x-19. Solve for x, and we get that x=11, and plug in 11 for x into 11x+3, 11(11)+3=121+3=124.

The measure of angle ∠2 is 124.

The measure of angle ∠8 is 124.

The angles that are in the same position on a given two parallel lines intersected by a transversal line are called the corresponding angles.

Corresponding angles are always equal.

We can also have alternate angles which are always equal.

We can also have alternate interior and exterior angles which are equal.

The angles on the same side make upto 180 degrees

We have,

∠2 and ∠8 are alternate exterior angles.

This means,

∠2 = ∠8

We can write it as,

11x + 3 = 13x - 19

3 + 19 = 13x  - 11x

22 = 2x

x = 11

Now,

∠2 = 11x + 3 = 11 x 11 + 3 = 121 + 3 = 124

∠8 = 13x - 19 = 143 - 19 = 124

Thus,

The measures of ∠2 and ∠8 are 124.

On solving the provided question, we can say that the required probability is = 13/204.

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.

We need to check if lines ℓ and k are parallel. For two lines to be parallel, they must have the same slope and different y-intercepts.Let's compare the given lines:Line ℓ: y = 34x + 6Slope of line ℓ = 34Line k: y = 34x - 7Slope of line k = 34We see that the slope of lines ℓ and k is the same (34), which means that they could be parallel.

However, we still need to check if they have different y-intercepts. Line ℓ: y = 34x + 6 has a y-intercept of 6.Line k: y = 34x - 7 has a y-intercept of -7.So, lines ℓ and k have different y-intercepts, which means they are not parallel. Therefore, the correct answer is b) No.In slope-intercept form, the equation of a line is y = mx + b, where m is the slope of the line and b is its y-intercept. In this case, both lines have the same slope of 34 (the coefficient of x). The y-intercepts are different (+6 for line l and -7 for line k). Thus, the lines are not parallel.

The answer is option a) Yes. Lines ℓ and k are parallel to each other.

The two distinct lines defined by the following two equations in slope-intercept form are:

Line ℓ: y = 34x + 6

Line k: y = 34x - 7

To determine if the lines are parallel, we need to compare their slopes since two non-vertical lines are parallel if and only if their slopes are equal.

Both lines are in slope-intercept form, so we can immediately read off their slopes:

Line ℓ has a slope of 34, and line k has a slope of 34.

Both the lines ℓ and k have the same slope of 34.

y = -4/5x + 2 & y = -2/7x - 4/7

Step-by-step explanation:

(4x) - 5y = -10                                             (2x) - 7y = 4

Move 4x on the same side as -10            Move 2x on the same side as 4

-5y = 4x -10                                                -7y = 2x + 4

Divide -5 to both sides                              Divide -7 by both sides

That should isolate the y for both equations.

4x/-5 = -4/5x....-10/-5 = 2                            2x/-7 = -2/7x....4/-7 = -4/7

y = -4/5x + 2                                                y = -2/7x - 4/7

A. Another way to find the area of a trapezoid is by summing the areas of two triangles.
B. Area is the measurement of the amount of space occupied by a 2-dimensional shape.

A. Yes, there is another way to conceptualize the formula for the area of a trapezoid. Instead of using the formula A = (b1 + b2) * h / 2, you can think of it as the sum of the areas of two triangles. First, you find the area of the top triangle by multiplying the base by the height and dividing by 2.

Then, you find the area of the bottom triangle using the same method. Finally, you add the two triangle areas together to get the total area of the trapezoid. This approach helps visualize how the trapezoid can be divided into simpler shapes.

B. The concept of area refers to the measure of the amount of space occupied by a 2-dimensional shape. It quantifies the extent or size of a region or surface. Area is typically measured in square units, such as square inches, square feet, or square meters. It helps us compare and analyze the sizes of different shapes or regions.

For example, when calculating the area of a rectangle, we multiply the length by the width. Understanding the concept of area is important in various fields, including mathematics, physics, architecture, and design.
