To calculate the current stock price using the dividend discount model, we can use the formula:

Current Stock Price = D1 / (r - g)

Where:

D1 = Expected dividend in the next year

r = Required rate of return

g = Growth rate of dividends

D1 = $5.25

r = 13% or 0.13

g = 8% or 0.08

Using the formula, we can calculate the current stock price:

Current Stock Price = $5.25 / (0.13 - 0.08)

Current Stock Price = $5.25 / 0.05

Current Stock Price = $105

Therefore, the company's current stock price should be $105.

Variability between groups is due to the grouping factor.

The F ratio is a measure of the variability between groups relative to the variability within groups, but it is not the cause of the variability between groups.

In an experimental design, researchers often manipulate an independent variable to observe its effects on a dependent variable.

The independent variable is often a grouping factor, which means that participants are assigned to different groups based on some characteristic or condition.

Participants may be assigned to a treatment group or a control group, or they may be grouped based on age, gender, or some other factor.

The experiment is conducted, the dependent variable is measured in each group, and the researcher is interested in whether there are significant differences between the groups.

Variability between groups refers to the differences in the mean scores of the dependent variable between the different groups.

The grouping factor is the reason for the variability between groups.

This is because the different groups are defined by the levels of the grouping factor, and the participants within each group are assumed to be similar with respect to the dependent variable.

Any differences between the groups must be due to the effect of the grouping factor.

The F ratio, which is calculated by dividing the variability between groups by the variability within groups, is used to test whether the differences between the groups are statistically significant.

The F ratio is a measure of the extent to which the grouping factor explains the variability in the dependent variable, and a significant F ratio indicates that there are significant differences between the groups.

Variability between groups is due to the grouping factor, and the F ratio is used to test whether the differences between the groups are statistically significant.

Step-by-step explanation:

Based on the formula of the quadratic function y=-x^2+6x-5, we know that its graph is a downward-facing parabola that opens wide, with a vertex at (3,-14), and an axis of symmetry at x=3.

Based on the formula of the quadratic function y=-x^2+6x-5, we can determine several properties of its graph, including its shape, vertex, and axis of symmetry.

First, the negative coefficient of the x-squared term (-1) tells us that the graph will be a downward-facing parabola. The leading coefficient also tells us whether the parabola is narrow or wide. Since the coefficient is -1, the parabola will be wide.

Next, we can find the vertex using the formula:

Vertex = (-b/2a, f(-b/2a))

where a is the coefficient of the x-squared term, b is the coefficient of the x term, and f(x) is the quadratic function. Plugging in the values for our function, we get:

Vertex = (-b/2a, f(-b/2a))

= (-6/(2*-1), f(6/(2*-1)))

= (3, -14)

So the vertex of the parabola is at the point (3,-14).

Finally, we know that the axis of symmetry is a vertical line passing through the vertex. In this case, it is the line x=3.

60 ≤ 1.36x + 34 ≤ 85; To stay within the range, the usage should be between 19.1 and 37.5 HCF.

The correct compound inequality to represent the scenario is:

60 ≤ 1.36x + 34 ≤ 85

To solve for x, we need to isolate it in the middle of the inequality:

60 - 34 ≤ 1.36x ≤ 85 - 34

26 ≤ 1.36x ≤ 51

Finally, we divide by 1.36 to isolate x:

19.12 ≤ x ≤ 37.5

Therefore, the recommended range of water consumption is between 19.1 and 37.5 HCF. The answer is (D) 60 ≤ 1.36x + 34 ≤ 85; To stay within the range, the usage should be between 19.1 and 37.5 HCF.

To conserve water, many communities have developed water restrictions. The water utility charges a fee of $34, plus an additional $1.36 per hundred cubic feet (HCF) of water. The recommended monthly bill for a household is between $60 and $85 dollars per month. If x represents the water usage in HCF in a household, write a compound inequality to represent the scenario and then determine the recommended range of water consumption. (Round your answer to one decimal place.)

Divide the number of percent changes that fall within the range by the total number of percent changes to get the percentage.

What is percentage?

Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".

To find the percentage of percent changes that is 1 standard deviation away from the mean in Excel, you can follow these steps:

1. Enter the percent changes in a column in Excel.

Calculate the mean of the percent changes using the AVERAGE function.

2. Calculate the standard deviation of the percent changes using the STDEV.S function.

3. Calculate the lower and upper bounds of the range that is 1 standard deviation away from the mean. To do this, subtract the standard deviation from the mean to get the lower bound, and add the standard deviation to the mean to get the upper bound.

4. Use the COUNTIF function to count the number of percent changes that fall within the range of 1 standard deviation away from the mean.

Therefore,  Divide the number of percent changes that fall within the range by the total number of percent changes to get the percentage.

Here's an example formula:

Answer:

Mr. A initially paid approximately N8000 for the land.

Step-by-step explanation:

Step 1: Let's assume Mr. A initially purchased the land for a certain amount, which we'll call "x" in currency units.

Step 2: Mr. A sold the land to Mr. B at a profit of 10%. This means Mr. A sold the land for 110% of the amount he paid (1 + 10/100 = 1.10). Therefore, Mr. A received 1.10x currency units from Mr. B.

Step 3: Mr. B sold the land to Mr. C at a gain of 5%. This means Mr. B sold the land for 105% of the amount he paid (1 + 5/100 = 1.05). Therefore, Mr. B received 1.05 * (1.10x) currency units from Mr. C.

Step 4: According to the given information, Mr. C paid N1240 more for the land than Mr. A paid. This means the difference between what Mr. C paid and what Mr. A paid is N1240. So we have the equation: 1.05 * (1.10x) - x = N1240

Step 5: Simplifying the equation: 1.155x - x = N1240

Step 6: Solving for x: 0.155x = N1240

x = N1240 / 0.155

x ≈ N8000

Therefore, in conclusion, Mr. A initially paid approximately N8000 for the land.

Answer:

n  = -14

Step-by-step explanation:

Let us try to solve this equation for n;

     3x + 1 - 9  = 3(x + 2)  + n

i hope i got this right.

The correct answer is (2) 2. This means that the rate of change of the vector function h(t) at t=1 is a constant vector with magnitude 2.

The vector-valued function h(t) is defined as h(t) = ⟨tet, t^2et⟩. To find h'(1), we need to take the derivative of h(t) with respect to t, and then evaluate it at t=1.

Taking the derivative of h(t), component-wise, we get:

h'(t) = ⟨(te^t + e^t), (2te^t)⟩

Now, we can evaluate h'(1) by plugging in t=1:

h'(1) = ⟨(1e^1 + e^1), (2(1)e^1)⟩ = ⟨2e, 2e⟩

Since both components of h'(1) are equal, we can write it as:

h'(1) = 2⟨e, e⟩

Since the dot product of two equal vectors is equal to the square of their magnitude, we have:

h'(1) = 2||⟨e, e⟩||^2 = 2||e||^2 = 2

Therefore, the correct answer is (2) 2. This means that the rate of change of the vector function h(t) at t=1 is a constant vector with magnitude 2. This implies that the direction of the vector is not changing, but only its magnitude is increasing or decreasing at a constant rate.

Answer: Y=3x,3x+y=30

Step-by-step explanation:

Answer:

To solve this system of equations using the substitution method, we need to isolate one of the variables in one of the equations and substitute its expression into the other equation.

From the first equation, we can see that y = 3x. We can substitute this expression for y in the second equation, like this:

3x + y = 30

3x + (3x) = 30 (substituting y = 3x)

6x = 30

x = 5

Now we can substitute this value of x back into either equation to find the value of y. We'll use the first equation:

y = 3x

y = 3(5)
