Step-by-step explanation:

ARCH (Autoregressive Conditional Heteroscedasticity) models are estimated using Maximum Likelihood (ML) estimation. Regarding Question 7, if the model has the given conditional variance function, it corresponds to an ARCH(3) model.

In the case of ARCH models, the ML estimation process involves the following steps:

1. Specify the ARCH model: Determine the appropriate order of the ARCH model by analyzing the autocorrelation and partial autocorrelation functions of the squared residuals (or other suitable diagnostic tests). For example, an ARCH(3) model implies that the conditional variance at time t depends on the squared residuals at time t-1, t-2, and t-3.

2. Formulate the likelihood function: The likelihood function specifies the probability of observing the given data under the assumed ARCH model. In ARCH models, the likelihood function is constructed based on the assumption that the errors follow a normal distribution with mean zero and a time-varying conditional variance.

3. Maximize the likelihood function: The goal is to find the parameter values that maximize the likelihood function. This is typically achieved using numerical optimization techniques, such as the Newton-Raphson algorithm or the BFGS algorithm.

4. Estimate the parameters: Once the likelihood function is maximized, the estimated parameter values are obtained. These estimates represent the best-fitting values that maximize the likelihood of observing the given data.

Therefore, the answer to Question 7 is: ARCH(3).

a) Probability of hitting the black circle is closer to zero than 1.

b) Probability of hitting the white portion is closer to 1 than 0

To get the probability of getting any point in the given image, we have to first of all find the area of the square which is:

Area of Square = 9 * 9 = 81 sq. units

Area of Circle = π * 1.5² = 7.07 Sq.units

Area of white part = 81 - 7.07

Area of white part = 73.93 Sq.units

a) Probability of hitting the black circle = 7.07/81 = 0.095

This probability is closer to zero than 1.

b) Probability of hitting the white portion = 73.93/81 = 0.9127

This probability is closer to 1 than 0

The equation of the parabola that intersects the x-axis at points (-1, 0) and (3,0) is y = 0.

Given that a parabola intersects the x-axis at points (-1, 0) and (3,0).We know that, when a parabola intersects the x-axis, the y-coordinate of the point on the parabola is 0. Therefore, the two x-intercepts tell us two points that are on the parabola.Thus the vertex is given by:Vertex is the midpoint of these x-intercepts=(x_1+x_2)/2=(-1+3)/2=1The vertex is the point (1,0).Since the vertex is at (1,0) and the parabola intersects the x-axis at (-1,0) and (3,0), the axis of symmetry is the vertical line passing through the vertex, which is x=1.We also know that the parabola opens upwards because it intersects the x-axis at two points.To find the equation of the parabola, we can use the vertex form:y = a(x - h)^2 + kwhere (h, k) is the vertex and a is a constant that determines how quickly the parabola opens up or down.We have h=1 and k=0.Substituting in the x and y values of one of the x-intercepts, we get:0 = a(-1 - 1)^2 + 0Simplifying, we get:4a = 0a = 0Substituting in the x and y values of the other x-intercept, we get:0 = a(3 - 1)^2 + 0Simplifying, we get:4a = 0a = 0Since a = 0, the equation of the parabola is:y = 0(x - 1)^2 + 0Simplifying, we get:y = 0Hence the equation of the parabola that intersects the x-axis at points (-1, 0) and (3,0) is y = 0.

Answer:

Cant you just look it up?

Step-by-step explanation:

The probability that an individual prefers biking given that he or she is 35 years old or older is 9/53.

From the definition of the probability we can get,

Conditional Probability to occur event A when B is already occurred is,

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

Now let A be the event that an individual prefers biking and B be the event that individual is 35 years old or older.

Number of 35 years old and older individual is = 159

Number of 35 years old and older preferred biking = 27

Total number of individual = 516

So, P(A and B) = 27/516 and P(B) = 159/516

So the required probability that an individual prefers biking given that he or she is 35 years old or older is

= P(A | B)

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

= (27/516)/(159/516)

= (27/516) * (516/159)

= 27/159

= 9/53

Hence, the required probability that an individual prefers biking given that he or she is 35 years old or older is 9/53.

Answer:

To solve the polynomial (g^2 + 9g + 18 = 0) using the X or Box method, you need to factor the polynomial into two binomials. To do this, you need to find two numbers that multiply to 18 and add up to 9. The two numbers are 6 and 3, so the polynomial can be factored as:

g^2 + 9g + 18 = (g + 6)(g + 3) = 0

To find the solutions, you set each factor equal to 0 and solve for g:

g + 6 = 0, so g = -6

g + 3 = 0, so g = -3

The solutions to the polynomial are g = -6 and g = -3.

In order for the parallelogram to be a rhombus, x must equal 55.

A rhombus is a quadrilateral that has four equal sides.

Some of the properties we need to know are:

- The opposite sides are parallel to each other.

- The opposite angles are equal.

- The adjacent angles add up to 180 degrees.

We have,

If a parallelogram is a rhombus, it means that all four sides of the parallelogram have equal length.

We can set the expressions for the opposite sides of the parallelogram equal to each other and solve for x.

x + 15 = 2x - 40

First, we can simplify by adding 40 to both sides and getting:

x + 55 = 2x

Next, we can subtract x from both sides and get:

55 = x

Therefore,

In order for the parallelogram to be a rhombus, x must equal 55.

To verify this, we can substitute x = 55 back into the expressions for the sides:

x + 15 = 55 + 15 = 70

2x - 40 = 2(55) - 40 = 70

Both opposite sides have an equal length of 70, so the parallelogram is a rhombus.

Thus,

In order for the parallelogram to be a rhombus, x must equal 55.

The solution of the given initial value problem. ty' + (t+1) y = t, y(ln 8) = 1, t> 0 is \(\\y = 1 - 1/t + (8/(ln 8)) * e^(^-^t^)\)

To solve the given initial value problem, we'll use the method of integrating factors.

The given differential equation is:

ty' + (t + 1)y = t

Rewrite the equation in the standard form:

y' + (t + 1)/t * y = 1

The integrating factor (IF) is given by the exponential of the integral of the coefficient of y, which in this case is (t + 1)/t:

\(IF = te^t + Ce^t\)

Multiplying both sides of the differential equation by the integrating factor, we have:

\(te^t * y' + (t + 1)e^t * y = te^t\)

Now, we can simplify the left side using the product rule:

\((te^t * y)' = te^t\)

After integrating both sides with respect to t, we obtain:

\(= te^t - e^t + C\)

Dividing both sides by \(te^t\), we get:

\(y = 1 - 1/t + Ce^(^-^t^)\)

Now, we can use the initial condition y(ln 8) = 1 to find the value of C.

Substituting ln 8 for t and 1 for y in the equation, we have:

\(1 = 1 - 1/(ln 8) + Ce^(^-^(^l^n^ 8^)^)\\1 = 1 - 1/(ln 8) + C/8\)

Simplifying:

\(0 = -1/(ln 8) + C/8\)

Multiplying through by 8(ln 8), we get:

\(0 = -8 + C(ln 8)\\C(ln 8) = 8\\C = 8/(ln 8)\)

Therefore, the solution to the initial value problem is:

\(y = 1 - 1/t + (8/(ln 8)) * e^(^-^t^)\)

The solution is valid for t > 0.

Ex = 438, Ey = 276, Ex² = 32264, Ey² = 12806, Exy = 20295 and r = 0.823

From the question, we have the following parameters that can be used in our computation:

X 67 64 75 86 73 73

Y 42 40 48 51 44 51

From the above, we have

Ex = 67 + 64 + 75 + 86 + 73 + 73 = 438

Also, we have

Ey = 42 + 40 + 48 + 51 + 44 + 51 = 276

To calculate Ex² and Ey², we have

Ex² = 67² + 64² + 75² + 86² + 73² + 73² = 32264

Ey² = 42² + 40² + 48² + 51² + 44² + 51² = 12806

Next, we have

Exy = 67 * 42 + 64 * 40 + 75 * 48 + 86 * 51 + 73 * 44 + 73 * 51 = 20295

The correlation coefficient (r) is calculated as

r = [n * Exy - Ex * Ey]/[√(n * Ex² - (Ex)²) * (n * Ey² - (Ey)²]

Substitute the known values in the above equation, so, we have the following representation

r = [6 * 20295 - 438 * 276]/[√(6 * 32264 - (438)²) * (6 * 12806 - (276)²]
