Since both triangles are right triangles, we can apply the Pythagorean theorem:

c^2 = a^2 + b^2

Where:

c = hypotenuse ( the longest side )

a & b = the other 2 legs of the triangle

for the left side triangle ( T1 )

9^2 = 6^2 + y^2

Let's label "y" the missing side on triangle 1 , which is a common side for both triangles.

81 = 36 + y^2

81 - 36 = y^2

45 = y^2

√45 = y

Now, with triangle 2:

x^2 = 8^2 + (√45)^2

Solve for x

x ^2 = 64 + 45

x^2 = 109

So the amount of gain that can be deferred under the installment sale method is $424,879.16.

Percent is a way of expressing a number as a fraction of 100. The word "percent" means "per hundred" in Latin. When a number is expressed as a percentage, it is usually accompanied by the "%" symbol. Percentages are commonly used in many areas of everyday life, such as finance, taxes, and statistics. They are often used to express changes or differences, such as percentage increases or decreases in prices or quantities, or the percentage of people who hold a certain opinion or belong to a certain group.

Here,

To calculate the gain that can be deferred under the installment sale method, we need to first calculate the total gain on the sale. The total gain is equal to the selling price minus the adjusted basis of the property, which is the cost minus the accumulated depreciation.

Selling price = $99,800 cash + $998,000 note = $1,097,800

Adjusted basis = $798,400 - $479,040 = $319,360

Total gain = $1,097,800 - $319,360 = $778,440

To calculate the gain that can be deferred, we need to determine the gross profit percentage. The gross profit percentage is equal to the total gain divided by the selling price:

Gross profit percentage = Total gain / Selling price = $778,440 / $1,097,800 ≈ 0.7097 or 70.97%

Now we can calculate the amount of gain that can be deferred using the formula:

Gain deferred = Gross profit percentage × Payments received

Since the note is due in two years, Skylar will receive half of the payments in 2022 and the other half in 2023. Therefore, the payments received in 2022 are:

$99,800 + ($998,000 / 2) = $598,800

Substituting into the formula, we get:

Gain deferred = 0.7097 × $598,800 = $424,879.16

a) The mean weight of pineapples grown in the field this year is different from the mean weight of pineapples grown last year. b) The power to detect an increase of 2 ounces in the mean weight of pineapples (μa = 33 ounces) is approximately 0.932, and the probability of making a Type 2 error with a true mean of 33 ounces is approximately 0.068.

(a) The null hypothesis (H0) and alternative hypothesis (Ha) can be written as follows:

Null Hypothesis (H0): The mean weight of pineapples grown in the field this year is equal to the mean weight of pineapples grown last year (μ = 31 ounces).

Alternative Hypothesis (Ha): The mean weight of pineapples grown in the field this year is different from the mean weight of pineapples grown last year (μ ≠ 31 ounces).

(b) To calculate the power and the probability of making a Type 2 error, we need to assume the population mean weight of pineapples this year (μa) is 33 ounces. We also need to determine the critical value for the given significance level (α) of 0.05.

Given that the sample size (n) is 30, the population standard deviation (σ) is 4 ounces, and the mean weight under the alternative hypothesis (μa) is 33 ounces, we can calculate the test statistic (z) using the formula:

z = (\(\bar x\) - μa) / (σ / √n)

where \(\bar x\) is the sample mean.

With \(\bar x\) = 31 ounces, σ = 4 ounces, μa = 33 ounces, and n = 30, we can calculate the test statistic:

z = (31 - 33) / (4 / √30)

z = -2 / (4 / √30)

z = -2 / (4 / 5.477)

z = -2 / 1.0954

z ≈ -1.825

Using a standard normal distribution table or calculator, we can find the corresponding p-value for this z-value. Let's assume it is approximately 0.034 (one-tailed test).

The power of the test can be calculated as 1 minus the probability of a Type 2 error. Since the alternative hypothesis is two-sided, we divide the significance level (α) by 2 and find the corresponding critical z-value. Let's assume it is approximately 1.96 (two-tailed test).

Now we can calculate the power using the formula:

Power = 1 - P(Type 2 Error) = 1 - P(z < -1.96 or z > 1.96)

P(Type 2 Error) = P(z < -1.96 or z > 1.96) ≈ 2 * P(z < -1.96) (assuming symmetry)

P(Type 2 Error) ≈ 2 * 0.034 ≈ 0.068

The chance of seeing a plate with the first digit being strictly less than the second one depends on the number of possible digits. Assuming the digits range from 0-9, there are 10 possible digits.

For the first digit, it can be any number from 0-8 (as it must be strictly less than the second digit). For each of these 9 options, there are different numbers of possibilities for the second digit:

- If the first digit is 0, there are 9 options for the second digit (1-9).
- If the first digit is 1, there are 8 options for the second digit (2-9).
- If the first digit is 2, there are 7 options for the second digit (3-9).
- And so on, until the first digit is 8, with only 1 option for the second digit (9).

To calculate the total number of possibilities with the first digit being strictly less than the second, you add up the options for the second digit: 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45. There are 100 total possibilities (10 digits for the first spot multiplied by 10 digits for the second spot). Therefore, the chance of seeing a plate with the first digit being strictly less than the second one is: 45/100 = 0.45 or 45%., So, there is a 45% chance of seeing a plate with the first digit being strictly less than the second one.

Question 1a

To calculate the book value at the end of the first year using straight-line depreciation, we need to determine the annual depreciation expense first. The straight-line method assumes that the asset depreciates by an equal amount each year over its useful life. Therefore, we can use the following formula to calculate the annual depreciation:

Annual Depreciation = (Cost - Salvage Value) / Useful Life

Substituting the given values, we get:

Annual Depreciation = ($200,000 - $20,000) / 10 years = $18,000 per year

This means that the tractor will depreciate by $18,000 each year for the next 10 years.

To determine the book value at the end of the first year, we need to subtract the depreciation expense for the year from the original cost of the tractor. Since one year has passed, the depreciation expense for the first year will be:

Depreciation Expense for Year 1 = $18,000

Therefore, the book value of the tractor at the end of the first year will be:

Book Value = Cost - Depreciation Expense for Year 1

= $200,000 - $18,000

= $182,000

So the book value of the tractor at the end of the first year, December 31, 2022, using straight-line depreciation is $182,000. so the answer is D

Question 1(b)

To determine the farmer's noncurrent liabilities, we need to use the information provided to calculate the total liabilities and then subtract the current liabilities from it. Here's the step-by-step solution:

Calculate the total current liabilities using the current ratio:

Current Ratio = Current Assets / Current Liabilities

2 = $80,000 / Current Liabilities

Current Liabilities = $80,000 / 2

Current Liabilities = $40,000

Calculate the total liabilities using the debt/equity ratio:

Debt/Equity Ratio = Total Liabilities / Owner Equity

1.0 = Total Liabilities / $100,000

Total Liabilities = $100,000 * 1.0

Total Liabilities = $100,000

Subtract the current liabilities from the total liabilities to get the noncurrent liabilities:

Noncurrent Liabilities = Total Liabilities - Current Liabilities

Noncurrent Liabilities = $100,000 - $40,000

Noncurrent Liabilities = $60,000

Therefore, the farmer's noncurrent liabilities are $60,000. so the answer is B.

Given the following 2nd-order differential equation (Cauchy-Euler equation), \(x^2y''+4xy'-4y=0\), find the general solution.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A differential equation in the form \(ax^2y''+bxy'+cy=0\) , which is a Cauchy-Euler equation, can be solved in the following manner.

Where the characteristic equation => \(am^2+(b-a)m+c=0\)

After solving for "m" the possible solutions are...

\(\bold{Real, \ Distinct \ Roots} \Rightarrow y=c_1x^{m_1}+c_2x^{m_2}\\\bold{ Repea ted \ Roots} \Rightarrow y=c_1x^{m}+c_2x^{m}ln(x)\\\bold{Complex \ Roots} \Rightarrow y=c_1x^{\alpha}cos(ln(x^\beta ))+c_2x^{\alpha}sin(ln(x^\beta )); \ m= \alpha \pm \beta i\)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

\(\Longrightarrow x^2y''+4xy'-4y=0 \ where \ a=1, \ b=4, \ and \ c=-4\)

The characteristic equation:

\(\Longrightarrow (1)m^2+(4-1)m+(-4)=0 \Longrightarrow \boxed{m^2+3m-4=0}\)

Solve for "m."

\(\Longrightarrow m^2+3m-4=0 \Longrightarrow (m-1)(m+4)=0 \Longrightarrow \boxed{m=1,-4}\)

Note that m's are distinct and real.

\(Thus, \ \boxed{y=c_1x+c_2x^{-4}} \therefore Sol.\)

Where the arbitrary constants c_1 and c_2 can be solved for given an initial condition.

The correct answer is option (e) \($y = c_1 x + c_2 x^2$\).

We can use the Cauchy-Euler equation to find the general solution of the given differential equation. The Cauchy-Euler equation is given by:

\($a_n x^n y^{(n)}+a_{n-1} x^{n-1} y^{(n-1)}+\cdots+a_1 x y^{\prime}+a_0 y=0$\)

where \($a_n, a_{n-1}, \ldots, a_1, a_0$\) are constants and \($y^{(n)}, y^{(n-1)}, \ldots, y'$\) denote the \($n$\)th, \($(n-1)$\)th, \($\ldots$\), first derivatives of y with respect to x.

In the given differential equation, we have \($a_2 = 1$\), \($a_1 = 4$\), and \($a_0 = -4$\). Therefore, the Cauchy-Euler equation becomes:

\($x^2 y^{\prime \prime}+4 x y^{\prime}-4 y=0$\)

We assume a solution of the form \($y=x^r$\). Substituting this into the differential equation, we get:

\($$x^2 r(r-1) x^{r-2}+4 x r^1 x^{r-1}-4 x^r=0$$\)

Simplifying, we get:

\($$\begin{aligned}& r(r-1)+4 r-4=0 \\& r^2+3 r-4=0 \\& (r+4)(r-1)=0\end{aligned}$$\)

So, we have two roots\($r_1 = -4$\) and \($r_2 = 1$\). Therefore, the general solution of the differential equation is:

\($y=c_1 x^{-4}+c_2 x^1$\)

Thus, the correct answer is option (e) \($y = c_1 x + c_2 x^2$\).

In this problem, we are dealing with a random variable related to people's opinions on a new building project. We are given four options for the correct wording of the random variable and need to determine the correct one. Additionally, we are asked to calculate probabilities associated with the number of people who favor the new building project, ranging from exactly 4 to at most 6.

a) The correct wording for the random variable is "rv = the number of people who are in favor of a new building project." This wording accurately represents the random variable as the count of individuals who support the project.

b) To calculate the probability that exactly 4 people favor the new building project, we need to use the binomial probability formula. Assuming the probability of a person favoring the project is p, we can calculate P(X = 4) = (number of ways to choose 4 out of 10) * (p^4) * ((1-p)^(10-4)). The value of p is not given in the problem, so this calculation requires additional information.

c) To find the probability that less than 4 people favor the new building project, we can calculate P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3). Again, the value of p is needed to perform the calculations.

d) The probability that more than 4 people favor the new building project can be calculated as P(X > 4) = 1 - P(X ≤ 4) = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)).

e) The probability that exactly 6 people favor the new building project can be calculated as P(X = 6) using the binomial probability formula.

f) To find the probability that at least 6 people favor the new building project, we can calculate P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10).

g) Finally, to determine the probability that at most 6 people favor the new building project, we can calculate P(X ≤ 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6).

Step-by-step explanation:

Angle CBD or k is equal to 70 degrees.

Angles are formed when two rays, known as the sides of the angle, share a common endpoint, called the vertex of the angle. The size of an angle is measured in degrees or radians. In a geometric plane, angles are usually denoted by a symbol that indicates the vertex, with the vertex being the middle letter, and the two rays are represented as line segments originating from the vertex.

Angles can be classified in different ways, including by their size or magnitude, by their position or direction, and by their relationships with other angles. Some common types of angles include acute angles (less than 90 degrees), right angles (exactly 90 degrees), obtuse angles (greater than 90 degrees but less than 180 degrees), straight angles (exactly 180 degrees), and reflex angles (greater than 180 degrees). Angles can also be complementary (adding up to 90 degrees), supplementary (adding up to 180 degrees), or congruent (having the same size).

We know that the sum of the angles in a triangle is 180 degrees. Let's use that fact to solve for k.

Angle ABD + angle CBD + angle ABC = 180 degrees

Substituting the given values, we get:

30 + k + 80 = 180

Combining like terms, we get:

k + 110 = 180

Subtracting 110 from both sides, we get:

k = 70

Therefore, angle CBD or k is equal to 70 degrees.
