To write an equation for the translation of y = 6/x that has the asymptotes x = 4 and y = 5, we can start by considering the translation of the function.

1. Start with the original equation: y = 6/x
2. To translate the function, we need to make adjustments to the equation.
3. The asymptote x = 4 means that the graph will shift 4 units to the right.
4. To achieve this, we can replace x in the equation with (x - 4).
5. The equation becomes: y = 6/(x - 4)
6. The asymptote y = 5 means that the graph will shift 5 units up.
7. To achieve this, we can add 5 to the equation.
8. The equation becomes: y = 6/(x - 4) + 5

Therefore, the equation for the translation of y = 6/x that has the asymptotes x = 4 and y = 5 is y = 6/(x - 4) + 5.

Now, the equation becomes y = 6/(x - 4).

To translate the equation vertically, we need to add or subtract a value from the equation. Since the asymptote is y = 5, we want to translate the equation 5 units upward. Therefore, we add 5 to the equation.

Now, the equation becomes y = 6/(x - 4) + 5.

So, the equation for the translation of y = 6/x with the asymptotes x = 4 and y = 5 is y = 6/(x - 4) + 5.

This equation represents a translated graph of the original function y = 6/x, where the graph has been shifted 4 units to the right and 5 units upward.

The given equation is y = 6/x. To translate this equation with the asymptotes x = 4 and y = 5, we can start by translating the equation horizontally and vertically.

To translate the equation horizontally, we need to replace x with (x - h), where h is the horizontal translation distance.

Since the asymptote is x = 4, we want to translate the equation 4 units to the right. Therefore, we substitute x with (x - 4) in the equation.

Now, the equation becomes y = 6/(x - 4).

To translate the equation vertically, we need to add or subtract a value from the equation.

Since the asymptote is y = 5, we want to translate the equation 5 units upward. Therefore, we add 5 to the equation.

The equation for the given problem is 9x - 9 = -108. To solve for x, we need to simplify the equation and isolate the variable.

Let's break down the problem step by step.

The first part states "nine times a number," which can be represented as 9x, where x is the unknown number.

The next part says "nine subtracted from," so we subtract 9 from 9x, resulting in 9x - 9.

Finally, the problem states that this expression is equal to -108, giving us the equation 9x - 9 = -108.

To solve for x, we need to isolate the variable on one side of the equation. We can do this by performing inverse operations.

First, we add 9 to both sides of the equation to eliminate the -9 on the left side, resulting in 9x = -99.

Next, we divide both sides by 9 to isolate x. By dividing -99 by 9, we find that x = -11.

Therefore, the number we're looking for is -11.

To find the Laplace transform of the solution x(t) to the initial value problem x'' + tx' - x = 0, where x(0) = 0 and x'(0) = 3, we first need to compute L{tx'(t)}.

We'll start by finding the Laplace transform of x'(t), denoted by X'(s). Then we'll use this result to compute L{tx'(t)}.

Taking the Laplace transform of the given differential equation, we have:

s^2X(s) - sx(0) - x'(0) + sX'(s) - x(0) - X(s) = 0

Substituting x(0) = 0 and x'(0) = 3, we have:

s^2X(s) + sX'(s) - X(s) - 3 = 0

Next, we solve this equation for X'(s):

s^2X(s) + sX'(s) - X(s) = 3

We can rewrite this equation as:

s^2X(s) + sX'(s) - X(s) = 0 + 3

Now, let's differentiate both sides of this equation with respect to s:

2sX(s) + sX'(s) + X'(s) - X'(s) = 0

Simplifying, we get:

2sX(s) + sX'(s) = 0

Factoring out X'(s) and X(s), we have:

(2s + s)X'(s) = -2sX(s)

3sX'(s) = -2sX(s)

Dividing both sides by 3sX(s), we obtain:

X'(s) / X(s) = -2/3s

Now, integrating both sides with respect to s, we get:

ln|X(s)| = (-2/3)ln|s| + C

Exponentiating both sides, we have:

|X(s)| = e^((-2/3)ln|s| + C)

|X(s)| = e^(ln|s|^(-2/3) + C)

|X(s)| = e^(ln(s^(-2/3)) + C)

|X(s)| = s^(-2/3)e^C

Since X(s) represents the Laplace transform of x(t), and x(t) is a real-valued function, |X(s)| must be real as well. Therefore, we can remove the absolute value sign, and we have:

X(s) = s^(-2/3)e^C

Now, we can solve for the constant C using the initial condition x(0) = 0:

X(0) = 0

Substituting s = 0 into the expression for X(s), we get:

X(0) = (0)^(-2/3)e^C 0 = 0 * e^C 0 = 0

Since this equation is satisfied for any value of C, we conclude that C can be any real number.

Therefore, the Laplace transform of x(t), denoted by X(s), is given by:

X(s) = s^(-2/3)e^C where C is any real number.

The derivative of the function f(t) = (7t + 4)/(5t − 1) at the point (3, 25/14) is -3/14.At the point (3, 25/14), the function f(t) = (7t + 4)/(5t − 1) has a derivative of -3/14, indicating a negative slope.

To evaluate the derivative of the function f(t) = (7t + 4) / (5t - 1) at the point (3, 25/14), we'll first find the derivative of f(t) and then substitute t = 3 into the derivative.

To find the derivative, we can use the quotient rule. Let's denote f'(t) as the derivative of f(t):

f(t) = (7t + 4) / (5t - 1)

f'(t) = [(5t - 1)(7) - (7t + 4)(5)] / (5t - 1)^2

Simplifying the numerator:

f'(t) = (35t - 7 - 35t - 20) / (5t - 1)^2

f'(t) = (-27) / (5t - 1)^2

Now, substitute t = 3 into the derivative:

f'(3) = (-27) / (5(3) - 1)^2

      = (-27) / (15 - 1)^2

      = (-27) / (14)^2

      = (-27) / 196

So, the derivative of f(t) at the point (3, 25/14) is -27/196.The derivative represents the slope of the tangent line to the curve of the function at a specific point.

In this case, the slope of the function f(t) = (7t + 4) / (5t - 1) at t = 3 is -27/196, indicating a negative slope. This suggests that the function is decreasing at that point.

The equation of the tangent line to the serpentine curve at the point (3, 0.30) is y = -0.08x + 0.54.

To find the equation of the tangent line to the serpentine curve at the point (3, 0.30), we need to find the slope of the tangent line at that point. We can do this by taking the derivative of the function y = x/(1 + x²) and evaluating it at x = 3.

Taking the derivative of y = x/(1 + x²) with respect to x, we get:

dy/dx = (1 + x²)(1) - x(2x)/(1 + x²)²

= (1 + x² - 2x²)/(1 + x²)²

= (1 - x²)/(1 + x²)²

Now, let's evaluate the derivative at x = 3:

dy/dx = (1 - (3)²)/(1 + (3)²)²

= (1 - 9)/(1 + 9)²

= (-8)/(10)²

= -8/100

= -0.08

So, the slope of the tangent line at the point (3, 0.30) is -0.08.

Next, we can use the point-slope form of the equation of a line to find the equation of the tangent line. The point-slope form is:

y - y₁ = m(x - x₁),

where (x₁, y₁) is the given point on the line and m is the slope.

Using the point (3, 0.30) and the slope -0.08, we have:

y - 0.30 = -0.08(x - 3).

Simplifying, we get:

y - 0.30 = -0.08x + 0.24.

Now, rearranging the equation to the slope-intercept form, we have:

y = -0.08x + 0.54.

So, the equation of the tangent line to the serpentine curve at the point (3, 0.30) is y = -0.08x + 0.54.

The test statistic represents a measure of compatibility between the null hypothesis and the data in tests of significance about an unknown parameter.

In hypothesis testing, we compare the observed data to what we would expect if the null hypothesis were true. The test statistic is a calculated value that quantifies the extent to which the observed data deviates from what is expected under the null hypothesis.

It is important to note that the test statistic is not directly related to the value of the unknown parameter. Instead, it provides a measure of how well the data align with the null hypothesis.

By comparing the test statistic to critical values or p-values, we can determine the level of evidence against the null hypothesis. If the test statistic falls in the critical region or the p-value is below the chosen significance level, we reject the null hypothesis in favor of the alternative hypothesis.

Therefore, the test statistic serves as a measure of compatibility between the null hypothesis and the data, helping us assess the strength of evidence against the null hypothesis.

The rate of heat flow out of the sphere is 0 kW.

To find the rate of heat flow out of a sphere of radius 1 inside a large cube of copper, we need to calculate the surface integral of the gradient of the temperature function w(x, y, z) over the surface of the sphere.

First, let's calculate the gradient of w(x, y, z):

∇w = (∂w/∂x)i + (∂w/∂y)j + (∂w/∂z)k

∂w/∂x = -6x

∂w/∂y = -6y

∂w/∂z = -6z

So, ∇w = -6xi - 6yj - 6zk

The surface integral of ∇w over the surface of the sphere can be calculated using spherical coordinates. In spherical coordinates, the surface element dS is given by dS = r^2sinθdθdφ, where r is the radius of the sphere (1 in this case), θ is the polar angle, and φ is the azimuthal angle.

Since the surface is a sphere of radius 1, the limits of integration for θ are 0 to π, and the limits for φ are 0 to 2π.

Now, let's calculate the surface integral:

−K∬ S ∇wdS = −K∫∫∫ ρ^2sinθdθdφ

−K∬ S ∇wdS = −K∫₀²π∫₀ᴨ√(ρ²sin²θ)ρdθdφ

−K∬ S ∇wdS = −K∫₀²π∫₀ᴨρ²sinθdθdφ

−K∬ S ∇wdS = −K∫₀²π∫₀ᴨρ²sinθ(-6ρsinθ)dθdφ

−K∬ S ∇wdS = 6K∫₀²π∫₀ᴨρ³sin²θdθdφ

Since we are integrating over the entire sphere, the limits for ρ are 0 to 1.

−K∬ S ∇wdS = 6K∫₀²π∫₀ᴨρ³sin²θdθdφ

−K∬ S ∇wdS = 6K∫₀²π∫₀ᴨ(ρ³/2)(1 - cos(2θ))dθdφ

−K∬ S ∇wdS = 6K∫₀²π[(ρ³/2)(θ - (1/2)sin(2θ))]|₀ᴨdφ

−K∬ S ∇wdS = 6K∫₀²π[(1/2)(θ - (1/2)sin(2θ))]|₀ᴨdφ

−K∬ S ∇wdS = 6K∫₀²π[(1/2)(0 - (1/2)sin(2(0)))]dφ

−K∬ S ∇wdS = 6K∫₀²π(0)dφ

In this case, the function f(x)=-4|x| is continuous at x=0 because the limit as x approaches 0 from the left (-4(-x)) and the limit as x approaches 0 from the right (-4x) both equal 0, and the function value at x=0 is also 0.

To check for differentiability at a point, we need to verify if the derivative of the function exists at that point. In this case, the function f(x)=-4|x| is not differentiable at x=0 because the derivative does not exist at x=0. The derivative from the left is -4 and the derivative from the right is 4, so there is a sharp corner or cusp at x=0.

III. f has an absolute maximum at x=0:

To determine if a function has an absolute maximum at a specific point, we need to compare the function values at that point to the values of the function in the surrounding interval.

We obtain the eigenvector: v2 = [x, y] = [(-42 + 24√37) / (5√37), (-3√37 + 8) / 5]. These are the eigenvectors corresponding to the eigenvalues of the matrix.

To find the equilibria of the system and determine their stability, we need to solve the equation y' = 2y - 3y^2 for y. Setting y' equal to zero gives us: 0 = 2y - 3y^2. Next, we factor out y: 0 = y(2 - 3y). Setting each factor equal to zero, we find two possible equilibria: y = 0 or 2 - 3y = 0. For the second equation, we solve for y: 2 - 3y = 0, y = 2/3. So the equilibria are y = 0 and y = 2/3. To determine the stability of each equilibrium, we can evaluate the derivative of y' with respect to y, which is the second derivative of the original equation: y'' = d/dy(2y - 3y^2 = 2 - 6y

Now we substitute the values of y for each equilibrium: For y = 0

y'' = 2 - 6(0)= 2. Since y'' is positive, the equilibrium at y = 0 is unstable.

For y = 2/3: y'' = 2 - 6(2/3)= 2 - 4= -2. Since y'' is negative, the equilibrium at y = 2/3 is locally stable. Now let's sketch the phase plot and describe the long-term behavior of the system: The phase plot is a graph that shows the behavior of the system over time. We plot y on the vertical axis and y' on the horizontal axis. We have two equilibria: y = 0 and y = 2/3.

For y < 0, y' is positive, indicating that the system is moving away from the equilibrium at y = 0. As y approaches 0, y' approaches 2, indicating that the system is moving upward. For 0 < y < 2/3, y' is negative, indicating that the system is moving towards the equilibrium at y = 2/3. As y approaches 2/3, y' approaches -2, indicating that the system is moving downward. For y > 2/3, y' is positive, indicating that the system is moving away from the equilibrium at y = 2/3. As y approaches infinity, y' approaches positive infinity, indicating that the system is moving upward.

Based on this analysis, the long-term behavior of the system can be described as follows: For initial conditions with y < 0, the system moves away from the equilibrium at y = 0 and approaches positive infinity. For initial conditions with 0 < y < 2/3, the system moves towards the equilibrium at y = 2/3 and settles at this stable equilibrium. For initial conditions with y > 2/3, the system moves away from the equilibrium at y = 2/3 and approaches positive infinity.

Now let's find the eigenvectors and corresponding eigenvalues for the given matrices:(a) Matrix:

| 2 1 |

To find the eigenvectors and eigenvalues, we solve the equation (A - λI)v = 0, where A is the matrix, λ is the eigenvalue, I is the identity matrix, and v is the eigenvector. Substituting the given matrix into the equation, we have:

| 1/2 - λ 2 | | x | | 0 |

| 2 1 - λ | | y | = | 0 |

Expanding and rearranging, we get the following system of equations:

(1/2 - λ)x + 2y = 0, 2x + (1 - λ)y = 0. Solving this system of equations, we find: (1/2 - λ)x + 2y = 0 [1], 2x + (1 - λ)y = 0 [2]. From equation [1], we can solve for x in terms of y: x = -2y / (1/2 - λ). Substituting this value of x into equation [2], we get: 2(-2y / (1/2 - λ)) + (1 - λ)y = 0. Simplifying further:

-4y / (1/2 - λ) + (1 - λ)y = 0

-4y + (1/2 - λ - λ/2 + λ^2)y = 0

(-7/2 - 3λ/2 + λ^2)y = 0

For this equation to hold, either y = 0 (giving a trivial solution) or the expression in the parentheses must be zero: -7/2 - 3λ/2 + λ^2 = 0. Rearranging the equation: λ^2 - 3λ/2 - 7/2 = 0. To find the eigenvalues, we can solve this quadratic equation. Using the quadratic formula: λ = (-(-3/2) ± √((-3/2)^2 - 4(1)(-7/2))) / (2(1)). Simplifying further:

λ = (3/2 ± √(9/4 + 28/4)) / 2

λ = (3 ± √37) / 4

So the eigenvalues for matrix (a) are λ = (3 + √37) / 4 and λ = (3 - √37) / 4.

To find the eigenvectors corresponding to each eigenvalue, we substitute the eigenvalues back into the system of equations: For λ = (3 + √37) / 4: (1/2 - (3 + √37) / 4)x + 2y = 0 [1], 2x + (1 - (3 + √37) / 4)y = 0 [2]

Simplifying equation [1]: (-1/2 - √37/4)x + 2y = 0

Simplifying equation [2]: 2x + (-3/4 - √37/4)y = 0

For λ = (3 - √37) / 4, the system of equations would be slightly different:

(-1/2 + √37/4)x + 2y = 0 [1]

2x + (-3/4 + √37/4)y = 0 [2]

Solving these systems of equations will give us the corresponding eigenvectors.

Analyzing the characteristics of respondents and non-respondents can provide insights into potential biases and help address any discrepancies.

The survey results are at risk for a type of bias known as non-response bias. Non-response bias occurs when a subset of individuals chosen to participate in a survey does not respond, leading to potential differences between the respondents and non-respondents. In this case, the employees in the human resources department who were hired in the past two years are required to respond to the questionnaire within five days.

Non-response bias can arise due to various reasons. Some employees may choose not to participate in the survey because they are dissatisfied or unhappy with their job, leading to a skewed representation of employee satisfaction. On the other hand, employees who are highly satisfied or have positive experiences may be more motivated to complete the survey, leading to an overrepresentation of their views. This can result in an inaccurate picture of overall employee satisfaction within the department.

To minimize non-response bias, the manager could consider implementing strategies such as reminders, follow-ups, or incentives to encourage higher response rates.

Additionally, analyzing the characteristics of respondents and non-respondents can provide insights into potential biases and help address any discrepancies.

To compare a confidence interval obtained from a sample to a worldwide result, you would typically check if the worldwide result falls within the confidence interval.

A confidence interval is an estimate of the range within which a population parameter, such as a mean or proportion, is likely to fall. It is computed based on the data from a sample. The confidence interval provides a range of plausible values for the population parameter, taking into account the uncertainty associated with sampling variability.

To compare the confidence interval to a worldwide result, you would first determine the population parameter value that represents the worldwide result. For example, if you are comparing means, you would identify the mean value from the worldwide data.

Next, you check if the population parameter value falls within the confidence interval. If the population parameter value is within the confidence interval, it suggests that the sample result is consistent with the worldwide result. If the population parameter value is outside the confidence interval, it suggests that there may be a difference between the sample and the worldwide result.

It's important to note that the comparison between the confidence interval and the worldwide result is an inference based on probability. The confidence interval provides a range of values within which the population parameter is likely to fall, but it does not provide an absolute statement about whether the sample result is significantly different from the worldwide result. For a more conclusive comparison, further statistical tests may be required.

The Gauss-Seidel iteration method is an iterative technique used to solve a system of linear equations.

It is an improved version of the Jacobi iteration method. It is based on the decomposition of the coefficient matrix of the system into a lower triangular matrix and an upper triangular matrix.

The Gauss-Seidel iteration method uses the previously calculated values in order to solve for the current values.

The Gauss-Seidel iteration method converges if and only if the spectral radius of the iteration matrix is less than one. Spectral radius: The spectral radius of a matrix is the largest magnitude eigenvalue of the matrix. In order to determine whether the Gauss-Seidel iteration converges for the system, the spectral radius of the iteration matrix has to be less than one. If the spectral radius is less than one, then the iteration converges, and otherwise, it diverges.

Let's consider the system: 10x + 2y + z = 22x + 10y - z = 2-2x + 3y + 10z = 22

In order to use the Gauss-Seidel iteration method, the given system should be written in the form Ax = b. Let's represent the system in matrix form.⇒ AX = B     ⇒    X = A-1 B

To show that A−B = A−(A∩B), we need to show that A−B is a subset of A−(A∩B) and that A−(A∩B) is a subset of A−B. Let x be an element of A−B. This means that x is in A and x is not in B.

By definition of set difference, if x is not in B, then x is not in A∩B. So, x is in A−(A∩B), which shows that A−B is a subset of A−(A∩B). Let x be an element of A−(A∩B). This means that x is in A and x is not in A∩B. By definition of set intersection, if x is not in A∩B, then x is either in A and not in B or not in A. So, x is in A−B, which shows that A−(A∩B) is a subset of A−B. Therefore, we have shown that A−B = A−(A∩B).

2. To show that A∩B = A∪B, we need to show that A∩B is a subset of A∪B and that A∪B is a subset of A∩B. Let x be an element of A∩B. This means that x is in both A and B, so x is in A∪B. Therefore, A∩B is a subset of A∪B. Let x be an element of A∪B. This means that x is in A or x is in B (or both). If x is in A, then x is also in A∩B, and if x is in B, then x is also in A∩B. Therefore, A∪B is a subset of A∩B. Therefore, we have shown that A∩B = A∪B.

3. To show that (A−B)−C = (A−C)−(B−C), we need to show that (A−B)−C is a subset of (A−C)−(B−C) and that (A−C)−(B−C) is a subset of (A−B)−C. Let x be an element of (A−B)−C. This means that x is in A but not in B, and x is not in C. By definition of set difference, if x is not in C, then x is in A−C. Also, if x is in A but not in B, then x is either in A−C or in B−C. However, x is not in B−C, so x is in A−C.

Therefore, x is in (A−C)−(B−C), which shows that (A−B)−C is a subset of (A−C)−(B−C). Let x be an element of (A−C)−(B−C). This means that x is in A but not in C, and x is not in B but may or may not be in C. By definition of set difference, if x is not in B but may or may not be in C, then x is either in A−B or in C. However, x is not in C, so x is in A−B. Therefore, x is in (A−B)−C, which shows that (A−C)−(B−C) is a subset of (A−B)−C. Therefore, we have shown that (A−B)−C = (A−C)−(B−C).

The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem. In this case, with the lengths of the legs being a = 55 and b = 132, the length of the hypotenuse is calculated as c = √(a^2 + b^2). Therefore, the length of the hypotenuse is approximately 143.12 units.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). Mathematically, it can be expressed as c^2 = a^2 + b^2.

In this case, the lengths of the legs are given as a = 55 and b = 132. Plugging these values into the formula, we have c^2 = 55^2 + 132^2. Evaluating this expression, we find c^2 = 3025 + 17424 = 20449.

To find the length of the hypotenuse, we take the square root of both sides of the equation, yielding c = √20449 ≈ 143.12. Therefore, the length of the hypotenuse is approximately 143.12 units.

The coordinates of the center of mass of the solid are (5.33, 2.5, 0.5).The center of mass of a solid with variable density is found by using the following formula:\bar{x} = \frac{\int_R \rho(x, y, z) x \, dV}{\int_R \rho(x, y, z) \, dV},

where R is the region of the solid, $\rho(x, y, z)$ is the density of the solid at the point (x, y, z), and dV is the volume element.

In this case, the region R is given by the set of points (x, y, z) such that 0 ≤ x ≤ 8, 0 ≤ y ≤ 5, and 0 ≤ z ≤ 1. The density of the solid is given by ρ(x, y, z) = 2 + x/3.

The integrals in the formula for the center of mass can be evaluated using the following double integrals:

```

\bar{x} = \frac{\int_0^8 \int_0^5 (2 + x/3) x \, dx \, dy}{\int_0^8 \int_0^5 (2 + x/3) \, dx \, dy},

```

```

\bar{y} = \frac{\int_0^8 \int_0^5 (2 + x/3) y \, dx \, dy}{\int_0^8 \int_0^5 (2 + x/3) \, dx \, dy},

\bar{z} = \frac{\int_0^8 \int_0^5 (2 + x/3) z \, dx \, dy}{\int_0^8 \int_0^5 (2 + x/3) \, dx \, dy}.

Evaluating these integrals, we get $\bar{x} = 5.33$, $\bar{y} = 2.5$, and $\bar{z} = 0.5$.

The center of mass of a solid is the point where all the mass of the solid is concentrated. It can be found by dividing the total mass of the solid by the volume of the solid.

In this case, the solid has a variable density. This means that the density of the solid changes from point to point. However, we can still find the center of mass of the solid by using the formula above.

The integrals in the formula for the center of mass can be evaluated using the change of variables technique. In this case, we can change the variables from (x, y) to (u, v), where u = x/3 and v = y. This will simplify the integrals and make them easier to evaluate.

After evaluating the integrals, we get $\bar{x} = 5.33$, $\bar{y} = 2.5$, and $\bar{z} = 0.5$. This means that the center of mass of the solid is at the point (5.33, 2.5, 0.5).

There are 55 integer values of n for which the expression [tex]4000 * (2/5)^n[/tex] is an integer, considering both positive and negative values of n.

To determine the values of n for which the expression is an integer, we need to analyze the factors of 4000 and the powers of 2 and 5 in the denominator.

First, let's factorize 4000: [tex]4000 = 2^6 * 5^3.[/tex]

The expression  [tex]4000 * (2/5)^n[/tex] will be an integer if and only if the power of 2 in the denominator is less than or equal to the power of 2 in the numerator, and the power of 5 in the denominator is less than or equal to the power of 5 in the numerator.

Since the powers of 2 and 5 in the numerator are both 0, we have the following conditions:

- n must be greater than or equal to 0 (to ensure the numerator is an integer).

- The power of 2 in the denominator must be less than or equal to 6.

- The power of 5 in the denominator must be less than or equal to 3.

Considering these conditions, we find that there are 7 possible values for the power of 2 (0, 1, 2, 3, 4, 5, and 6) and 4 possible values for the power of 5 (0, 1, 2, and 3). Therefore, the total number of integer values for n is 7 * 4 = 28. However, since negative values of n are also allowed, we need to consider their counterparts. Since n can be negative, we have twice the number of possibilities, resulting in 28 * 2 = 56.

However, we need to exclude the case where n = 0 since it results in a non-integer value. Therefore, the final answer is 56 - 1 = 55 integer values of n for which the expression is an integer.
