If the stock sells for $58 a share the Dragon company's cost of equity will be 8.97%.

The cost of equity is the return that investors require from the stock of the company. We have to use the DDM (Dividend discount model) here,

The formula for the DDM is,

P₀ = D₁/(ke - g), current stock price is P₀, the expected dividend per share in the next period is D₁, required rate of return (cost of equity) is ke, and expected growth rate of dividends  g.

In this case, we have,

D₁ = D₀ x (1 + g)

= $2.85 x (1 + 0.036)

= $2.95 (expected dividend per share in the next period)

P₀ = $58 (current stock price)

g = 0.036 (expected growth rate of dividends)

Substituting these values into the DDM formula, we get,

$58 = $2.95 / (ke - 0.036)

Solving for ke, we get,

ke = ($2.95 / $58) + 0.036

= 0.0897 or 8.97%

Therefore, Dragon Company's cost of equity is 8.97%.

The value of x is 3 in a right triangle for the u side angle having equation u = 9x+6.

Angle v = 57

Angle u =9x+6

The right angle triangle follows a rule that the sum of the two acute angles is 90 degrees. That means the angles u + v must be equal to 90 degrees.

v + u = 90

From the given angle equations, we can write

57 + 9x + 6 = 90

9x + 63 = 90

9x = 90-63

9x = 27

x = 27 ÷ 3

x = 3

The unit circle), and the curve does not oscillate rapidly or change direction abruptly, so we would expect the arc length to be less than 2.

To find the arc length traced out by the parametric curve x = cos(cos(4t)), y = sin(cos(4t)) as t goes through the range 0 to 1, we can use the following formula for arc length:

L = ∫√(dx/dt)^2 + (dy/dt)^2 dt, where the integral is taken over the range of t.

Taking the derivatives of x and y with respect to t, we have:

dx/dt = -sin(4t)sin(cos(4t))

dy/dt = cos(4t)sin(cos(4t))

Substituting these into the formula for arc length, we get:

L = ∫√((-sin(4t)sin(cos(4t)))^2 + (cos(4t)sin(cos(4t)))^2) dt

L = ∫√(sin^2(4t)sin^2(cos(4t)) + cos^2(4t)sin^2(cos(4t))) dt

L = ∫√(sin^2(cos(4t))) dt

L = ∫|sin(cos(4t))| dt

Since we know that the sine function oscillates between -1 and 1, we can see that the absolute value of sin(cos(4t)) is always between 0 and 1. Therefore, the integral of |sin(cos(4t))| over the range 0 to 1 gives us the total distance traced out by the curve, which is the arc length.

Evaluating the integral, we get:L = ∫|sin(cos(4t))| dt = ∫sin(cos(4t)) dt

Let u = cos(4t), then du/dt = -4sin(4t), and dt = -du/(4sin(4t))

Substituting for dt and u, we have:

L = ∫sin(u) * (-du/(4sin(4t))) = (-1/4) ∫sin(u) du = (-1/4)cos(u) + C

Substituting back for u and simplifying, we get:

L = (-1/4)cos(cos(4t)) + C

To find the constant C, we use the fact that L = 0 when t = 0:

0 = (-1/4)cos(cos(0)) + C = (-1/4)cos(1) + C

C = (1/4)cos(1)

Therefore, the arc length traced out by the parametric curve x = cos(cos(4t)), y = sin(cos(4t)) as t goes through the range 0 to 1 is:

L = (-1/4)cos(cos(4t)) + (1/4)cos(1)

L = (-1/4)cos(cos(4)) + (1/4)cos(1)

L ≈ 0.615

Mr. Billings needs to reduce his water usage to 2.7 HCF in order to have a water bill of less than $200.

We have,

To calculate Mr. Billings' water bill, we need to know how much water he used during the month of August.

Let's assume that he used x HCF of water.

We can then use the tiered billing rates to calculate his total water bill.

For the first 8 HCF, the billing rate is $3.64 per HCF,

so the cost for this tier is 3.64x.

For usage between 8 and 24 HCF, the billing rate is $4.08 per HCF,

so the cost for this tier is (24-8) x $4.08 = 61.44.

For usage between 24 and 36 HCF, the billing rate is $5.82 per HCF,

so the cost for this tier is (36-24) x $5.82 = 69.84.

For usage over 36 HCF, the billing rate is $8.19 per HCF,

so the cost for this tier is (x-36) x $8.19.

Now,

Total water bill

= $37.78 + 3.64x + 61.44 + 69.84 + (x-36) x $8.19

= $168.86 + 11.55x

To find the amount of water usage that Mr. Billings needs to reduce in order to have a water bill of less than $200, we can set the total water bill to $200 and solve for x:

$200 = $168.86 + 11.55x

$31.14 = 11.55x

x = 2.7 HCF

So,

Mr. Billings needs to reduce his water usage to 2.7 HCF in order to have a water bill of less than $200.

Similarly,

To find the amount of water usage that Mr. Billings needs to reduce in order to have a water bill of less than $150, we can set the total water bill to $150 and solve for x:

$150 = $168.86 + 11.55x

-$18.86 = 11.55x

x = -1.63 HCF

Since water usage cannot be negative, there is no solution to this problem. Therefore, it is not possible for Mr. Billings to have a water bill of less than $150, given his current water usage and the tiered billing rates.

Thus,

Mr. Billings needs to reduce his water usage to 2.7 HCF in order to have a water bill of less than $200.

The missing information for q3 is the sum of squares for error.The missing information for q4 is the mean squares for error, which can be calculated by dividing the sum of squares for error.To find the p-value for the above ANOVA table, we need to use the F-distribution with degrees of freedom for treatment  and degrees of freedom for error.

Using the given mean squares for treatment (25.25) and mean squares for error (2.95), we can calculate the F-statistic as follows:

F = mean squares for treatment / mean squares for error
F = 25.25 / 2.95
F = 8.5593

The p-value can then be calculated using a one-tailed F-test with alpha level of 0.05:

p-value = pf(F, degrees of freedom for treatment, degrees of freedom for error)
p-value = pf(8.5593, 3, 16)
p-value = 0.0006

Therefore, the answer is A.
Q2: Mean squares (treatment) = Sum of squares (treatment) / Degree of freedom (treatment)
Mean squares (treatment) = 75.75 / 3
Mean squares (treatment) = 25.25
So, the answer for q2 is: a. 25.25

Q3: Mean squares (error) = Sum of squares (error) / Degree of freedom (error)
Mean squares (error) = 47.2 / 16
Mean squares (error) = 2.95

Using the divergence test, we consider the limit of the general term as k approaches infinity:

lim (k→∞) (2+k)/(3-k²)

We can see that the denominator, k², grows much faster than the numerator, k. Therefore, as k approaches infinity, the term approaches zero. However, the denominator approaches infinity, meaning that the terms do not go to zero fast enough for the series to converge. Therefore, we can conclude that the series diverges.

For the second series, we have:

∑[infinity]k=1 (2e^k)/(3+k)

Using the divergence test, we consider the limit of the general term as k approaches infinity:

The expected number of patients experiencing flulike symptoms is 17.33.

Based on the information given, researchers selected 825 patients at random who take a certain widely-used prescription drug daily. In a clinical trial, 22 out of the 825 patients complained of flulike symptoms. The researchers' hypothesis is that more than 2.1% of this drug's users experience flulike symptoms as a side effect.

To test this hypothesis, we can use a one-tailed hypothesis test with a significance level of 0.01. The null hypothesis (H0) is that the proportion of patients experiencing flulike symptoms is equal to or less than 2.1%. The alternative hypothesis (Ha) is that the proportion of patients experiencing flulike symptoms is greater than 2.1%.

To calculate the test statistic, we first need to find the expected number of patients experiencing flulike symptoms under the null hypothesis. This is equal to the sample size (825) multiplied by the proportion of patients experiencing flulike symptoms under the null hypothesis (0.021). So, the expected number of patients experiencing flulike symptoms is 17.33.

Next, we can calculate the test statistic using the formula:

z = (x - μ) / σ

where x is the observed number of patients experiencing flulike symptoms (22), μ is the expected number of patients experiencing flulike symptoms under the null hypothesis (17.33), and σ is the standard deviation of the sampling distribution, which can be approximated by:

σ = sqrt[(p * (1 - p)) / n]

where p is the proportion of patients experiencing flulike symptoms under the null hypothesis (0.021) and n is the sample size (825).

Plugging in the values, we get:

z = (22 - 17.33) / sqrt[(0.021 * (1 - 0.021)) / 825] = 2.17

Looking up the critical value for a one-tailed test with a significance level of 0.01, we find that it is 2.33. Since our test statistic (2.17) is less than the critical value (2.33), we fail to reject the null hypothesis.

Therefore, we do not have sufficient evidence to conclude that more than 2.1% of this drug's users experience flulike symptoms as a side effect at the 0.01 level of significance.

In the given scenario, researchers selected 825 patients who take a certain prescription drug daily. Out of these, 22 patients experienced flulike symptoms. The hypothesis being tested is whether more than 2.1% of this drug's users experience flulike symptoms as a side effect at the α=0.01 level of significance. Since np₀(1-p₀) = 17.0 > 10, the sample size is less than 5% of the population size, and the patients were selected randomly, all requirements for testing the hypothesis are satisfied.

I understand you're asking about the volume percentage removed from a solid box when a cube is removed from each corner. Let's consider the dimensions of the original box as L cm x W cm x H cm. When a cube of side length x cm is removed from each corner, there are a total of 8 corners (since a box has 8 corners).

The volume of each removed cube is x^3 cubic cm. Since there are 8 cubes removed, the total volume removed is 8 * x^3 cubic cm. The volume of the original box is L * W * H cubic cm.

Now, to calculate the percentage of the original volume removed, we use the formula:

[tex]Percentage removed = (Total volume removed / Original volume) * 100[/tex]

In this case, it would be:

Percentage removed = (8 * x^3) / (L * W * H) * 100

First, set the seed to ensure the reproducibility of the random numbers. Then, use the generator to create a data set of the desired size, where each value represents the length.

To generate a data set of integer values ranging from 1 to 1000 (inclusive) with a desired size and a given seed for the random number generator, you can use the following steps:

1. Set the seed for the random number generator using the given seed value.
2. Generate the desired size of the data set, using the random number generator to generate a random integer value between 1 and 1000 (inclusive) for each value in the set. You can do this using a loop or a list comprehension, depending on your preference.
3. Each value in the data set represents the length, so you can use the generated integer value directly as the length for that value.

Here's some sample Python code that shows how to generate a data set of size 10 with a seed of 12345:

```
import random

seed_value = 12345
size = 10

random.seed(seed_value)
data_set = [random.randint(1, 1000) for i in range(size)]
```

This code sets the seed value to 12345, generates a data set of size 10, and stores the resulting list of integers in the `data_set` variable.
