Step-by-step explanation:

As per the question, Total Annual Cash Inflows = 5000, Discount Factor = 3.72 and New Machine's internal rate of return = 16%

Note: The query is not complete and does not contain the necessary information for part 4. It is impossible to fully answer this question without the exhibits stated in the questions. Up until part 3, we will be solving it.

1) The entire annual cash inflows must be calculated for this, and the formula is given below:

Total annual cash inflows are equal to the annual savings from part-time labor plus the additional contribution margin from anticipated sales.

Annual Cash Inflows Total = 3800 + ( 1000 x 1.20)

= 3800 + 1200

= 5000

2. Formula for figuring up the discount percentage:

Discount Factor = New Machine Price/Annual Cash Flow

New machine cost is 18600 USD.

Annual inflow of cash = 5000

Discount Factor is equal to 18600/5000.

Discount Ratio is 3.72.

3.  The examples, which are absent from this question, show that the discount factor for six years is roughly closest to 16%, hence the internal rate of return for the new machine is equal to 16%.

Note, without the exhibits indicated in the questions, the question is insufficient and cannot be utilized in Part 4. It cannot be solved any further.

f( x ) is an odd function

The symmetry of a function is described using the terms even and odd. On a graph, an even function is symmetric about the y-axis. An odd function has symmetric behavior around a graph's origin (0, 0).

According to the given information

We are given with the function

f( x ) = [tex]-9-x^{5} + 2x^{3}[/tex]

For checking that the function is even or odd

Case 1

put -x in place of x

f ( -x ) = [tex]-9-(-x)^{5} + 2(-x)^{3}[/tex]

f ( -x ) = [tex]-9+x^{5} -2x^{3}[/tex]

f(x) ≠ f (-x)

Hence it is not an even function

So

Answer: 0.25 inches per hour.

Step-by-step explanation:

The mile-a-minute weed can grow up to 0.5 ft per day. To convert this to inches per hour, we need to convert the distance from feet to inches and the time from days to hours.

There are 12 inches in 1 foot, so the mile-a-minute weed can grow up to 0.5 x 12 = <<0.5*12=6>>6 inches per day.

There are 24 hours in 1 day, so the mile-a-minute weed can grow up to 6 / 24 = <<6/24=0.25>>0.25 inches per hour.

Therefore, the mile-a-minute weed can grow up to 0.25 inches per hour.

Here's the complete solution using the correct conversion factors:

1 ft = 12 inches

1 day = 24 hours

0.5 ft/day * (12 inches/1 ft) / (24 hours/1 day) = 0.25 inches/hour

The factors of the polynomial  t¹² – r³s¹⁵ is (t⁴ + rs⁵)(t⁸ - rs⁵t⁴+ r²s¹⁰). The correct answer is B.

The definition of a factor is a number that completely divides another number. If adding two whole numbers results in an item, the numbers we are adding are variables of the item since the item can be used to separate them.

By using formula

(a³ - b³) = ( a+ b)( a² -ab + b²)

Then,

t¹² – r³s¹⁵ = (r⁴)³ - (rs⁵)³

=(r⁴ + rs⁵)((t⁴)² - rs⁵t⁴ + (r⁵)²)

=(r⁴ + rs⁵)(t⁸ - (rs⁵t⁴) + r²s¹⁰)

Answer:

Step-by-step explanation:

The required probability is 0.75 that a student visited the athletic complex regularly, given that he or she tried out for a sport.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

To find the probability that a student visited the athletic complex regularly, given that he or she tried out for a sport. This is known as the conditional probability of visiting the athletic complex regularly, given that the student tried out for a sport.

The formula for calculating conditional probability is:

P(A|B) = P(A and B) / P(B)

In this case, A is the event "visited the athletic complex regularly" and B is the event "tried out for a sport."

Substituting the given probabilities into the formula, we get:

P(A|B) = P(A and B) / P(B)

= 0.12 / 0.16

= 0.75

Therefore, the probability is 0.75, which is the correct answer that would be option (C).

Sampling bias, also known as sample selection bias, refers to flaws in research studies that arise when researchers do not appropriately select their subjects.

When a sample is collected in such a way that some members of the intended population have a significantly lower or higher sampling risk than others, sampling bias is reduced.

It yields a skewed sample of a population (or non-human variables) in which not all individuals, but rather cases, were picked in the same way. If this is not considered, the outcomes may be incorrectly attributed to the study problem rather than the sample method.

Sampling bias is often classified as a subset of selection bias, also known as sample selection bias, but some believe it to be a separate type of bias.

The difference between sampling bias and selection bias, though not frequently recognized, is that sampling bias reduces a test's external validity, whereas selection bias only addresses the internal validity of differences or similarities detected in the sample at hand.

The Equation for parallel line is: y= 4x - 13

The Equation for perpendicular line is: y= 1/4 x + 2

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

The passing point is (4, 3).

Now, the slope of given line

= Rise / Run

= 4 / 1

= 4

So, the slope for parallel line is 4 and for perpendicular line is -1/4.

Now, the line passes through (4, 3)

For parallel line

y= 4x+ b
