Answer: F. n = s/180 + 2

Step-by-step explanation:

         To find the equation that solves for n, we will isolate the n variable.

Given:

     S = (n - 2) x 180

Divide both sides of the equation by 180:

     \(\frac{S}{180}\) = n - 2

Add 2 to both sides of the equation:

     \(\frac{S}{180}\) + 2 = n

Reflexive property:

    n = \(\frac{S}{180}\) + 2

                   F. n = s/180 + 2

The Sturm-Liouville problem y'' + 2y' + y = 0 with boundary conditions y(0) = 0 and y(1) = 0 has eigenfunctions yn = 0 and eigenvalues λn = 0.

The equation is already in self-adjoint form, with the weight function p(x) = 1, and the eigenfunctions are orthogonal with a square norm of 0.

To solve the Sturm-Liouville problem y'' + 2y' + y = 0 with boundary conditions y(0) = 0 and y(1) = 0, we can follow these steps:

a) Find the eigenfunctions and eigenvalues:

Assume the solution has the form y(x) = yn(x), where n is an integer. Substitute this into the differential equation to obtain yn'' + 2yn' + yn = 0. The general solution to this equation is yn(x) = C1e^(-x) + C2xe^(-x), where C1 and C2 are constants. Applying the boundary conditions, we find that C1 = 0 and C2 = 0. Therefore, the eigenfunction is yn(x) = 0 for all n, and the eigenvalue is λn = 0 for all n.

b) Transform the equation to self-adjoint form and find the weight function:

To transform the equation to self-adjoint form, we multiply the equation by a weight function p(x). In this case, p(x) = 1. Multiplying the equation by p(x), we get y'' + 2y' + y = 0. This is already in self-adjoint form, as the coefficients of y'' and y' are equal.

c) Show orthogonality and find the square norm of eigenfunctions:

Since the eigenfunction yn(x) is zero for all n, it is orthogonal to the weight function p(x) = 1. The square norm of the eigenfunction yn(x) is given by ||yn||^2 = ∫[0,1] yn^2(x)p(x)dx = ∫[0,1] 0^2 dx = 0.

In summary, for the given Sturm-Liouville problem, the eigenfunction yn(x) is zero for all n and the eigenvalue is λn = 0 for all n. The equation is already in self-adjoint form, and the weight function is p(x) = 1. The eigenfunctions are orthogonal to the weight function, and their square norm is zero.

Answer:

If the third side is x, then

The perimeter is 5+19+x.

But every side must be less than the sum of the other

    two sides, so x < 5+19

                  x < 24

Adding 5+19 to both sides to make the left side

equal to the perimeter

 perimeter = x+5+19 < 24+5+19 = 48

So 48 is the smallest whole number that is larger than the

The Central Limit Theorem states that for a random sample of n observations drawn from any population with a finite mean μ and a finite standard deviation σ, the sampling distribution of the sample mean approaches a normal distribution as the sample size increases, regardless of the shape of the population distribution.

To apply the Central Limit Theorem, the following condition is necessary:

1. The random sample should be selected from a population that has a finite mean (μ) and a finite standard deviation (σ).

In this case, the population mean is given as $75 and the population standard deviation is given as $5. Since both the mean and standard deviation are finite, the condition for applying the Central Limit Theorem is satisfied.

The length of the ribbon to the nearest tenth is 50.3 inches.

To find the length of the ribbon that surrounds the edge of a circular hat that has a radius of 8 inches, we can use the formula for the circumference of a circle.

The formula for the circumference of a circle is given by the following:

C = 2πr

Where C represents the circumference of the circle, π represents the constant value of pi which is approximately equal to 3.14, and r represents the radius of the circle.

Given that the circular hat has a radius of 8 inches, we can use this value to find the circumference of the circle.

Hence, we have: r = 8 inches

C = 2πr

C = 2π(8)C = 16π

The length of the ribbon that surrounds the edge of the circular hat is equal to the circumference of the circle. Therefore, the length of the ribbon is:16π ≈ 50.3 inches (to the nearest tenth)

Therefore, the length of the ribbon to the nearest tenth is 50.3 inches.

Answer:

+10 + 10 + 10 -2 - 8

Step-by-step explanation:

1. Increasing alpha level from .01 to .05 decreases power by increasing the probability of Type II error.
2. Increasing effect size increases power by making it easier to detect a significant difference. Switching from one-tailed to two-tailed test decreases power by making it harder to reject the null hypothesis.

The power of a hypothesis test is influenced by several factors, including the alpha level, the type of test (one-tailed or two-tailed), and the effect size.

1. Increasing the alpha level from .01 to .05 decreases the power of a hypothesis test. This is because increasing the alpha level means that the researcher is willing to accept a higher probability of making a Type I error (rejecting the null hypothesis when it is actually true). This means that the critical value for rejecting the null hypothesis is less extreme, making it easier to reject the null hypothesis. However, this also means that the probability of making a Type II error (failing to reject the null hypothesis when it is actually false) increases, which decreases the power of the test.

2. Changing from a one-tailed test to a two-tailed test affects the power of a hypothesis test. A one-tailed test has a directional hypothesis, where the researcher is only interested in whether the value of the test statistic is greater than or less than a certain value. A two-tailed test has a non-directional hypothesis, where the researcher is interested in whether the value of the test statistic is significantly different from a certain value. When changing from a one-tailed test to a two-tailed test, the critical value for rejecting the null hypothesis becomes more extreme, making it harder to reject the null hypothesis. This decreases the power of the test.

3. Increasing effect size increases the power of a hypothesis test. Effect size refers to the magnitude of the difference between the null hypothesis and the alternative hypothesis. A larger effect size means that the difference between the null hypothesis and the alternative hypothesis is more pronounced, making it easier to detect a significant difference. This increases the power of the test, as it reduces the probability of making a Type II error.

Step-by-step explanation:

f(x) = ( x² - 9) / (3x² + 6x - 9) The horizontal asymptote is y = 0 and The vertical asymptotes are x = -3 and x = 1.

To find the horizontal asymptotes, we examine the behavior of the function as x approaches positive infinity and negative infinity.

As x approaches positive infinity, the highest power of x in the numerator and denominator dominates the function. In this case, both the numerator and denominator have a highest power of x². Therefore, we can compare the coefficients of the highest power of x, which are 1 in the numerator and 3 in the denominator.

The ratio of the coefficients is 1/3. Since the ratio is less than 1, the horizontal asymptote is y = 0.

As x approaches negative infinity, we can perform the same analysis and find that the horizontal asymptote is also y = 0.

Therefore, the horizontal asymptote is y = 0.

To find the vertical asymptotes, we need to determine the values of x that make the denominator equal to zero, because division by zero is undefined.

In this case, the denominator is 3x² + 6x - 9. To find the values of x that make the denominator zero, we can set it equal to zero and solve for x:

3x² + 6x - 9 = 0

Simplifying the equation, we get:

x² + 2x - 3 = 0

Factoring the equation, we have:

(x + 3)(x - 1) = 0

Setting each factor equal to zero, we find:

x + 3 = 0 or x - 1 = 0

Solving for x, we get:

x = -3 or x = 1

Therefore, the vertical asymptotes are x = -3 and x = 1.

Answer:

x= 18

y =45

Step-by-step explanation:

first these two angles are supplementary and add up to 180 degrees:

(6x+7) + (4x-7) = 180

find x:

10x = 180

x = 18

substitute x = 18 for the angle (6x+7)

now we know what 6x +7 =

6 (18) + 7 = 115

since angle 3y-20 = 115, solve for y

3y = 135

y = 45

Answer:

x = 18

y = 45

Step-by-step explanation:

1. First off, we know that the angle (4x-7) degrees and (6x +7) are supplementary angles because of the corresponding angles theorem. So we do: (4x-7) + (6x+7) = 180 which should get you x=18.

2. Now that you know the value of x, finding y should be pretty easy. Plug in x for (6x + 7) and you should get 115 degrees.

3. We know that the angle with (6x +7) measurement is a vertical angle to (3y-20), so we can do 3y -20 = 115.

x = 12 and y = 9

Step-by-step explanation:

Using the similarity theorem to fid the value of x and y

16/x = 16+6/16.5

16/x = 22/16.5

22x = 16*16.5

22x = 264

x = 264/22

x =12

Similarly

24/x = 24+y/16.5

24/12 = 24+y/16.5

2 = 24+y/16.5

24+y = 2 * 16.5

24+y = 33

y = 33-24

y = 9

Hence x = 12 and y = 9

The probability of selecting a black checker from a bag of 6 black and 4 red checkers, replacing it, and selecting another black is 9/25.

To find the probability follow these-

Determine the probability of selecting a black checker on the first draw.

There are 6 black checkers and a total of 10 checkers (6 black + 4 red).

So, the probability of selecting a black checker on the first draw is 6/10,

which can be simplified to 3/5.

Since the black checker is replaced, there are still 6 black checkers and

a total of 10 checkers in the bag. Therefore, the probability of selecting a

black checker on the second draw is also 3/5.

To find the probability of both events occurring, multiply the probabilities together: (3/5) × (3/5) = 9/25.

So, the probability of selecting a black checker from a bag of 6 black and

4 red checkers, replacing it, and selecting another black is 9/25.
