Answer:

68 degrees

Step-by-step explanation:

The straight horizontal line is a straight angle with 180 degrees it is split in a way that you know under the right angle, is another right ange making up part of the 180° line, add 22 and then subtract what you get from 180 to get 68.

A simpler way, add the angles in the X and 22 degree things and there is a right angle, 90 degrees, subtract 22 from 90 and get 68

Two different ways, either will work

Solution to the given initial value problem is y = 9e^7x + 63e^49

To solve the initial value problem dy/dx = 9e^7, y(-7) = 0, we can integrate both sides of the equation with respect to x and apply the initial condition.

∫ dy = ∫ 9e^7 dx

Integrating, we have:

y = 9e^7x + C

Now, we can use the initial condition y(-7) = 0 to determine the value of the constant C:

0 = 9e^7(-7) + C

Simplifying:

0 = -63e^49 + C

C = 63e^49

Therefore, the solution to the initial value problem is:

y = 9e^7x + 63e^49

Expressed as y = f(x), the solution is:

f(x) = 9e^7x + 63e^49

There are 7 degrees of freedom for the pooled-variance t-test.

To perform a pooled-variance t-test, we need to calculate the degrees of freedom. The formula for degrees of freedom in a pooled-variance t-test is:

\(\[\text{{df}} = n_1 + n_2 - 2\]\)

where \(\(n_1\)\) and \(\(n_2\)\) are the sample sizes of the two independent samples.

In this case, \(\(n_1 = 4\)\) and \(\(n_2 = 5\)\). Substituting these values into the formula, we get:

\(\[\text{{df}} = 4 + 5 - 2 = 7\]\)

In a pooled-variance t-test, we combine the sample variances from two independent samples to estimate the population variance. The degrees of freedom for this test are calculated using the formula \(df = n1 + n2 - 2\), where \(n_1\)and \(n_2\) are the sample sizes of the two independent samples.

To understand why the formula is \(df = n1 + n2 - 2\), we need to consider the concept of degrees of freedom. Degrees of freedom represent the number of independent pieces of information available to estimate a parameter. In the case of a pooled-variance t-test, we subtract 2 from the total sample sizes because we use two sample means to estimate the population means, thereby reducing the degrees of freedom by 2.

In this specific case, the sample sizes are \(n1 = 4\) and \(n2 = 5\). Plugging these values into the formula gives us \(df = 4 + 5 - 2 = 7\). Hence, there are 7 degrees of freedom for the pooled-variance t-test.

Therefore, there are 7 degrees of freedom for the pooled-variance t-test.

Part a

The estimated population of fox in the year 2019  is 28511

Part b

The after 3 years the population will reach 22000

The population in 2013 = 17000

The growth rate = 9% per year

Therefore it is an exponential function

Consider the P(x) as the population in x years

The the exponential function

P(x) = 17000 × \((1+0.09)^x\)

We have to find the population in 2019

Number of years = 6

Substitute the values in the function

P(6) = 17000 × \((1.09)^6\)

= 28510.7

≈ 28511

Part b

The population of fox = 22000

22000 = 17000 × \(1.09^x\)

\(1.09^x\) = 22000/17000

\(1.09^x\) = 22/17

x = ln (22/17) / ln(1.09)

x = 2.99

x ≈ 3 years

Hence,

Part a

The estimated population of fox in the year 2019  is 28511

Part b

The after 3 years the population will reach 22000

The correct answer is the Beta-binomial model. Bayesian analysis is a statistical approach that incorporates prior knowledge or beliefs about a parameter of interest and updates it based on observed data using Bayes' theorem.

In the case of a binary choice, where the outcome can be either yes or no, Bayesian analysis seeks to estimate the probability of success (yes) based on available information.

The Beta-binomial model is a commonly used model in Bayesian analysis for binary data. It combines the Beta distribution, which represents the prior beliefs about the probability of success, with the binomial distribution, which describes the likelihood of observing a specific number of successes in a fixed number of trials.

The Beta distribution is a flexible distribution that is often used as a prior for modeling probabilities because of its ability to capture a wide range of shapes. The Beta distribution is characterized by two parameters, typically denoted as alpha and beta, which can be interpreted as the number of successes and failures, respectively, in the prior data.

The binomial distribution, on the other hand, describes the probability of observing a specific number of successes in a fixed number of independent trials. In the context of Bayesian analysis, the binomial distribution is used to model the likelihood of observing the data given the parameter of interest (probability of success).

By combining the prior information represented by the Beta distribution and the likelihood information represented by the binomial distribution, the Beta-binomial model allows for inference about the probability of success in a binary choice.

The other options mentioned, such as the Normal-normal model and the Gaussian model, are not typically used for binary data analysis. The Normal-normal model is more suitable for continuous data, where both the prior and likelihood distributions are assumed to follow Normal distributions. The Gaussian model is also suitable for continuous data, as it assumes that the data are normally distributed.

In summary, the Beta-binomial model is the appropriate model for Bayesian analysis of a binary choice because it effectively combines the Beta distribution as a prior with the binomial distribution as the likelihood, allowing for inference about the probability of success in the binary outcome.

Step-by-step explanation:

To determine if a system of two equations with two unknowns has infinite solutions using matrices, you can perform Gaussian elimination or row reduction on the augmented matrix of the system. If the reduced form of the matrix is the identity matrix, then the system has a unique solution. If the reduced form is a row of zeros except for the last column, then the system has no solution. If the reduced form has a row with all zeros except for the last column being non-zero, then the system has an infinite number of solutions.

In other words, the system has infinite solutions if the row reduced form of the augmented matrix has a row of the form [0 0 c], where c is a non-zero scalar. This means that there is a non-trivial solution that satisfies the equation, indicating that there are infinitely many solutions.

The integral expression of the volume of the solid generated when r is roated about the horizantal line y=6 is, V = π∫[f(y)]^2 dy

Let's consider the region bounded by the function r=f(y) and the horizontal line y=6 in the xy-plane, where r represents the distance between the y-axis and a point on a curve.

When this region is rotated around the horizontal line y=6, it generates a solid whose volume can be expressed as an integral in terms of y as follows:

V = π∫[f(y)]^2 dy

Here, the limits of integration are determined by the range of y-values for which the curve exists within the region bounded by the x-axis and the line y=6.

Note that we have not evaluated this integral yet since we do not have enough information about the specific function f(y).

Determined by various factors such as sample size, statistical significance, and the chosen level of confidence. the probability that the test will fail to decide that the true value is 72.5 when it is indeed 72.5.  

In order to calculate the probability of a Type II error, one would need to know the specific details of the test being used, such as the sample size, the statistical power of the test, and the chosen level of significance.

In general, the probability of a Type II error increases as the sample size decreases and the level of significance decreases. This means that if the test being used is not sufficiently powered or if the level of confidence is too low, there is a higher probability of failing to detect a true effect.

If the test is not able to accurately determine if the statement is true or not when the actual value is 72.5, then there is a possibility that a Type II error has occurred. The probability of this error depends on the specific details of the test being used and cannot be determined without further information.

The probability of a test failing to decide a certain hypothesis is true, when it is actually true, can be determined using the concept of Type II error or false negative rate. In statistical hypothesis testing, Type II error (β) refers to the probability of failing to reject a false null hypothesis. These factors influence the power of the test, which is the probability of correctly rejecting the null hypothesis when it is false. The power of the test (1 - β) is complementary to the probability of making a Type II error.

In this case, the null hypothesis (H0) could be that the value is not equal to 72.5,

while the alternative hypothesis (H1) states that the value is equal to 72.5.

The probability you are looking for is the Type II error rate when the true value is 72.5.

Answer: 2=x

Step-by-step explanation: -x+3 = 2x + 1 , 2 = x

The power series for the function `f(x) = 2/(3x^2)`, centered at `c=3` is given by:`f(x) = 2/27 - 4/243(x-3) + 1/81(x-3)² - 4/243(x-3)³ + ...`

Given the function `f(x) = 2/(3x^2)` and `c=3`.

We are to find the power series for the given function centered at c.

Now, we know that the power series representation for `f(x)` is given by:`

f(x) = ∑(n=0 to ∞) cn (x-c)n`Where `cn = fⁿ(c)/n!`

We will first differentiate the function `f(x)` n times and then substitute `x=c`.`f(x) = 2/(3x²)``f'(x) = -4/(9x³)``f''(x) = 24/(81x^4)``f'''(x) = -96/(243x^5)`

Now, we will substitute `x=3` in the above expressions.

`f(3) = 2/(3(3²))

= 2/27``f'(3)

= -4/(9(3³))

= -4/243``f''(3)

= 24/(81(3^4))

= 8/243``f'''(3)

= -96/(243(3^5))

= -32/243`

Hence, the coefficients `cn` are:`

c₀ = f(3)/0!

= 2/27``c₁

= f'(3)/1!

= -4/243``c₂

= f''(3)/2!

= 8/(2*243)

= 1/81``c₃

= f'''(3)/3!

= -32/(3*243)

= -4/243

`Therefore, the power series representation of `f(x)` is given by:`f(x) = ∑(n=0 to ∞) cn (x-c)n``f(x) = c₀ + c₁(x-c) + c₂(x-c)² + c₃(x-c)³ + ...``f(x) = 2/27 - 4/243(x-3) + 1/81(x-3)² - 4/243(x-3)³ + ...`

Hence, the power series for the function `f(x) = 2/(3x^2)`, centered at `c=3` is given by:`f(x) = 2/27 - 4/243(x-3) + 1/81(x-3)² - 4/243(x-3)³ + ...`
