The power of substitutes is one of the five forces in Porter's Five Forces framework and it is a measure of how easy it is for customers to switch to alternative products or services. The higher the power of substitutes, the more competitive the industry and the lower the profitability.

The power of substitutes is based on the premise that when there are readily available alternatives to a product or service, customers can easily switch to those alternatives if they offer better value or meet their needs more effectively. This poses a threat to the industry as it reduces customer loyalty and puts pressure on pricing and differentiation strategies.

The availability and quality of substitutes influence the degree to which customers are likely to switch. If substitutes are abundant and offer comparable or superior features, the power of substitutes is strong, increasing the competitive intensity within the industry. On the other hand, if substitutes are limited or inferior, the power of substitutes is weak, providing more stability and protection to the industry.

Let's assume the total number of movies Aldo plans to watch each month is represented by the variable "M". To write an equation representing the total number of movies Aldo will watch in months, we can use the equation:

M = n * m

where "n" represents the number of months and "m" represents the average number of movies Aldo plans to watch per month.

This equation states that the total number of movies Aldo will watch (M) is equal to the number of months (n) multiplied by the average number of movies he plans to watch per month (m).

For example, if Aldo plans to watch an average of 5 movies per month and he plans to do so for 12 months, the equation becomes:

M = 12 * 5

which simplifies to:

M = 60

Therefore, Aldo plans to watch a total of 60 movies in 12 months.

For the mean age of Netflix customers, a 98% confidence interval can be constructed using the sample mean, sample standard deviation, and the appropriate critical value from the t-distribution.

Explanation:

To construct the confidence interval, we can use the formula:

Confidence Interval = sample mean ± (critical value * standard error)

The critical value is obtained from the t-distribution based on the desired confidence level (98%) and the degrees of freedom (sample size minus 1). The standard error is calculated as the sample standard deviation divided by the square root of the sample size.

Being 98% confident means that if we were to repeat this survey multiple times and construct 98% confidence intervals for the mean age of Netflix customers, approximately 98% of those intervals would contain the true population mean age.

It provides a high level of certainty about the range of values within which the population mean age is likely to fall.

Answer:

  9x +y = 12

Step-by-step explanation:

You want the standard form equation for the line with slope -9 through the point (2, -6).

The point-slope form equation is a good place to start when given a point and a slope. That equation is ...

  y -k = m(x -h) . . . . line with slope m through point (h, k)

  y -(-6) = -9(x -2) . . . . line with slope -9 through point (2, -6)

This can be rearranged to the desired form:

  y +6 = -9x +18 . . . . . . eliminate parentheses

  9x +y = 12 . . . . . . . . add 9x -6

Yes, i agree with hector. The polygon in above figure is irregular due to unequal side lengths and Hector also states that it is not regular or irregular.

A polygon is a 2-D geometric figure that has a finite number of sides. The sides are equal in length. It is a closed shape formed by end to end joining of straight line segments. For examples of regular polygons are square, rhombus, equilateral triangle, etc.

An irregular polygon, also called a non-regular polygon. It is a shape that does not have all sides of equal length and all angles of equal. For examples scalene triangle, rectangle, kite etc. are examplses of irregular polygon.

Now, we have a polygon present in above figure. As we see that this figure has 8 sides and length of one side is equal to its opposite side, but all sides are not equal length. So, it is an irregular polygon. Hector also states that above figure is irregular polygon. Hence, i agree with hector.

The area of the rectangle would be 96 square inches.

Option (D) is correct.

What is the area of the rectangle?

The formula for the area of a rectangle is:

Area = length x width

where length is the distance along the longer side of the rectangle and width is the distance along the shorter side of the rectangle.

In the given figure,

The length of the rectangle = 8 + 8 = 16 inches.

Now by using the Pythagoras theorem, we can find the height

  \(Height= \sqrt{(10)^2-(8)^2} \\\\=\sqrt{100-64}\\\\=\sqrt{36}\\\\=6\)

So the base would be 6 inches.

Now we can find the area of the rectangle

Area = 16 * 6

Area = 96 square inches.

Hence, the area of the rectangle would be 96 square inches.

The slope of the segment \(\overline{DC}\) of the line DA is equivalent to the slope of the segment \(\overline{BA}\), which is 2/5. Therefore;

Slope of \(\overline{DC}\) = \(\frac{2}{5}\)

The slope, m, of a graph with points (x₁, y₁), and (x₂, y₂) can be found using the formula;

\(m = \frac{y_2 - y_1}{x_2-x_1}\)

The colinear points are; D, C, B, and A

The slope of the each section of a straight line graph are equivalent, therefore;

The slope of the line DA using the segment \(\overline{BA}\) is the same as the slope of the line DA found using the segment of the line \(\overline{DC}\).

The slope of a line is the ratio of the rise to the run of the line

Slope = Rise/Run

The rise of a segment of a line is the vertical elevation of the line segment, while the run of the segment of a segment of the line is the horizontal distance between the boundaries of the segment of the line.

The rise of the line between points A and B is 2 unit while the run of the segment \(\overline{BA}\) is 5 units.

The slope of \(\overline{BA}\) = (2 units)/(5 units) = 2/5

Answer:

Slope: 3

Equation: y + 2 = 3(x + 1)

Step-by-step explanation:

Find the slope using (-1, -2) and (0, 1):

\( slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - (-2)}{0 - (-1)} = \frac{3}{1} = 3 \)

Slope (m) = 3

The equation can be represented in point-slope form, y - b = m(x - a)

Where,

(-1, -2) = (a, b)

m = 3

Plug in the values into y - b = m(x - a)

y - (-2) = 3(x - (-1))

y + 2 = 3(x + 1)

The critical t-value is approximately 1.753.

To find the critical value for a 96% confidence interval with a sample size of 15, we need to determine the t-value from the t-distribution table. The t-distribution table is a statistical tool used to determine the probability of a t-value given the degrees of freedom (df) and the desired level of significance (α).

In this case, we have a sample size of 15, which means our degrees of freedom are 14 (n - 1). Looking at a t-distribution table for 14 degrees of freedom and a 96% confidence interval.

This means that if we were to construct a confidence interval from a sample size of 15, the margin of error would be calculated by multiplying the critical t-value of 1.753 by the standard deviation of the sample and dividing by the square root of the sample size. The resulting interval would contain the population mean with 96% confidence.

It's essential to note that the critical value will change as the sample size and confidence level change. Therefore, it's crucial to use the correct table to find the corresponding critical values for a given dataset's sample size and confidence level.

The numerical limits for a D grade: 59 to 64

In this question we have been given that the scores on the test are normally distributed with a mean of 70 and a standard deviation of 7.3

μ = 70, σ = 7.3

We need to find the numerical limits for a D grade

D: Scores below the top 79% and above the bottom 6%

So between the 6th and the 21st percentile.

6th percentile:

X when Z has a pvalue of 0.06. So X when Z = -1.555

Z = X - μ/σ

-1.555 = (X - 70)/7.3

X - 70 = -11.35

X = 58.65

X ≈ 59

21st percentile:

X when Z has a pvalue of 0.21. So X when Z = -0.81

Z = X - μ/σ

-0.81 = (X - 70)/7.3

X - 70 = -5.91

X = 64.09

X ≈ 64

Therefore, you get a D if you have a grade between 59 and 64

Sampling is the use of a subset of the population to represent the whole population or to inform about processes that are meaningful beyond the particular cases, individuals or sites studied.

In non-probability sampling, the sample is selected based on non-random criteria, and not every member of the population has a chance of being included. Common non-probability sampling methods include convenience sampling, voluntary response sampling, purposive sampling, snowball sampling, and quota sampling.

Answer:

c = 0.17w + 0.42

$1.10

Step-by-step explanation:

Let total cost = c.

Let number of ounces = w.

total cost = fixed cost + cost per ounce

fixed cost = $0.42

cost per ounce = $0.17

cost for w ounces = $0.17w

total cost = fixed cost + cost per ounce

     c         =       0.42    +        0.17w

The expression is:

c = 0.17w + 0.42

For 4 ounces, w = 4.

c = 0.17 × 4 + 0.42

c = 1.1

Answer:

c = 0.17w + 0.42
