The apothem is the perpendicular distance from the center of a regular polygon to any one of its sides.

The apothem of a regular polygon is the perpendicular distance from the center of the polygon to any one of its sides because it serves as a measure of the inradius, or the radius of the circle inscribed within the polygon. In a regular polygon, all sides are congruent and all interior angles are equal, so the apothem is the same for all sides.

To see this, imagine drawing radii from the center of the polygon to each vertex, and then drawing the perpendicular bisector of each side. These perpendicular bisectors will all intersect at the same point, which is the center of the polygon. The apothem is the length of the line segment connecting this center point to any one of the sides of the polygon.

The apothem is useful in finding the area of a regular polygon. By using the formula for the area of a regular polygon in terms of the apothem and the number of sides, one can find the area of a regular polygon without having to find the exact shape of the polygon.

The correct answer to the question "z scores that fall below the mean are" is "negative". Z-scores are measures of relative standing that can be used to make comparisons among the scores in the distribution by transforming raw data into standardized units.

The formula for z-score is:z = (X-μ)/σz-scores can be negative, zero, or positive numbers. A negative z-score tells us that the corresponding score is below the mean and vice versa.In addition to this, the mean of all z-scores is always zero. If the mean of all z-scores is zero, that means that z-scores are measuring deviation from the mean. If a z-score is below the mean, it means that the corresponding raw score is below the mean, which results in a negative z-score.

Z-scores that fall below the mean are negative. Z-scores are statistical values that allow analysts to transform raw data into standardized units that make comparisons possible among scores in the distribution. The formula for calculating the z-score is: z = (X-μ)/σThe z-score can be either negative, zero, or positive, depending on whether the value is below, equal to, or above the mean, respectively. Because the mean of all z-scores is always zero, z-scores can be used to measure deviation from the mean, with a negative z-score indicating that the corresponding raw score is below the mean. Z-scores allow us to compare the scores in the distribution by converting them into standard units. Negative z-scores are associated with scores that are below the mean. Conversely, positive z-scores are associated with scores that are above the mean.

Answer:Therefore, the sum of the first 39 terms of the AP is 2730.

Given that the 20th term of an AP is 92 and we need to find the sum of the first 39 terms of the AP. Let's find the common difference and first term of the AP using the information provided.The formula for the nth term of an AP is given by,

\(a_n = a + (n - 1) * d\)

Where a is the first term, d is the common difference, and n is the nth term.Given,

a_20 = 92a + (20 - 1) * d

= 92a + 19d = 92 ------------

(1)We can also write,

\(a_1 = a + (1 - 1) * d\)

= a

Also,

\(a_20 = a + (20 - 1) * d\)

So, 92 = a + 19d -------------

(2)On solving equations (1) and (2), we get,

a = 13, d = 3

Hence, the AP is 13, 16, 19, ..., we need to find the sum of the first 39 terms of this AP. The sum of the first n terms of an AP is given by,

\(S_n = n / 2 * (2a + (n - 1) * d)\)

Putting the values of a, d, and n, we get

\(S_39 = 39 / 2 * (2 * 13 + (39 - 1) * 3)\)

\(= 39 / 2 * (26 + 114)\)\)

Hence, the sum of the first 39 terms of the AP is 2730. Answer:Therefore, the sum of the first 39 terms of the AP is 2730.

Therefore, the mean of the sampling distribution of the proportion is 0.076 and the standard deviation is approximately 0.0189.

To be able to approximate the sampling distribution with a normal model, we need the following conditions to be met:

Random Sampling: The 240 loans should be randomly selected from the population of all loans. This ensures that the sample is representative of the population.

Independence: The loans should be independent of each other. This means that the default status of one loan does not affect the default status of another loan.

Success-Failure Condition: The number of successes (people who do not make payments on time) and failures (people who make payments on time) in the sample should each be at least 10. This ensures that the sampling distribution can be approximated using a normal model.

Now, let's calculate the mean and standard deviation of the sampling distribution of the proportion:

The mean of the sampling distribution of the proportion is equal to the population proportion, which is 7.6% or 0.076.

The standard deviation of the sampling distribution of the proportion can be calculated using the formula:

σ = √((p * (1 - p)) / n)

where p is the population proportion and n is the sample size.

In this case, p = 0.076 and n = 240.

σ = √((0.076 * (1 - 0.076)) / 240)

= √(0.07095 / 240)

29 - M = 2(I - M)

Simplifying this equation, we get:

2M - I = 29

Now we can use equation 1 to substitute I with M + 5:

2M - (M + 5) = 29

Simplifying this equation, we get:

M = 34

Ii is the estimated value of the integral at the ith iteration, and I is the overall estimated value of the integral. We can stop the algorithm when the standard deviation σ is less than 0.01.

The standard deviation (SD, also written as the Greek symbol sigma or the Latin letter s) is a statistic that is used to express how much a group of data values vary from one another.

To estimate the integral I = ∫[1 to 0] \(e^{(x^2)\) dx using Monte Carlo simulation, we can use the following algorithm:

To stop when the standard deviation of the estimator is less than 0.01, we can keep track of the estimated value of the integral and the number of points generated at each iteration of the algorithm. We can compute the standard deviation of the estimator using the formula:

σ = √((1/N) * Σ[i=1 to N] (Ii - I)²)

You go shopping with a total of 60 quarters-

The amount in dollars left is: $3.75

We know that initially, you had a total of 50 quarters, this will represent the 100% in this case.

50 = 100%

Then you find 20% more quarters.

We can write:

x = 20%

Taking the quotient between the two equations we et:

50/x = 100%/20%

50 = (5)*x

50/5 = x = 10

The 20% is 10 quarters more, then you go shopping with a total of 60 quarters.

Then you spend the 75% of the total, then you onle end up with the 25% of what you bring, then at the end you have:

The transformation rule that describes the rotation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

The rule that describes the transformation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

To understand this, let's apply the transformation rule to each vertex of the original parallelogram ABCD:

Point A (2, 5) becomes A' (-5, 2).

Point B (5, 4) becomes B' (-4, 5).

Point C (5, 2) becomes C' (-2, 5).

Point D (2, 3) becomes D' (-3, 2).

By applying the transformation rule, we observe that the x-coordinate of each point becomes the negative of the original y-coordinate, and the y-coordinate becomes the original x-coordinate.

This transformation is a 90-degree counterclockwise rotation about the origin (0, 0) on the coordinate plane. The image parallelogram A'B'C'D' is obtained by rotating the original parallelogram ABCD by 90 degrees counterclockwise.

Visually, this transformation can be seen as the original parallelogram being rotated around the origin, where the x-axis becomes the y-axis, and the y-axis becomes the negative x-axis.

Therefore, the transformation rule that describes the rotation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).
