The x-value at maximum profit is (100/599)^(1/3).

Given:

Price function: P = 100/√x

Cost function: C(x) = 600 + x

Profit = Revenue - Cost

= Px - C(x)

So, Profit function:

P(y) = y - (600 + (100/y²))y where y = √x (substituting y = √x in Price function)

P(y) = y - (600 + 100/y²)y

P(y) = y - 600y - 100/x

Where P(y) is the profit function.

x-value at maximum profit,

P'(y) = 0

Or, d/dy[y - 600y - 100/x] = 0

Or, 1 - 600 + 100/x³ = 0

Or, 100/x³ = 599

Or, x = (100/599)^(1/3)

So, the x-value at maximum profit is (100/599)^(1/3).

Hence, the required values are:

Profit function: P(y) = y - 600y - 100/x

X-value at maximum profit: (100/599)^(1/3)

Moving Average leads a trend, True. Mean Squared Error cannot be used to compare alternative forecasting methods, False. Delphi method uses multiple rounds for determining estimates, True.

True. Moving Average is a commonly used time series forecasting technique that calculates the average of a specified number of past data points to predict future values. It is known as a lagging indicator because it uses historical data to forecast trends. By smoothing out fluctuations in the data, moving averages provide a clearer picture of the underlying trend. Therefore, it can be said that moving averages lead a trend.

False. Mean Squared Error (MSE) is a measure used to assess the accuracy of a forecasting model by comparing its predicted values to the actual values. It calculates the average of the squared differences between the predicted and actual values. While MSE is a useful metric for evaluating the performance of a single forecasting method, it cannot be directly used to compare alternative forecasting methods.

This is because MSE values are scale-dependent, meaning they can vary depending on the units of measurement. In order to compare alternative methods, it is recommended to use other metrics like Mean Absolute Error (MAE) or forecasting accuracy measures such as Mean Absolute Percentage Error (MAPE).

True. The Delphi method is a forecasting technique that involves multiple rounds of gathering expert opinions to reach a consensus or determine estimates. In each round, a panel of experts provides their individual forecasts or opinions on a particular topic. These responses are collected, summarized, and fed back to the experts for further consideration. This process continues for several rounds until a convergence or consensus is reached.

The Delphi method is designed to harness the collective intelligence and expertise of a diverse group of experts while minimizing the influence of dominant individuals or group dynamics. The iterative nature of the Delphi method allows for refining and revising estimates based on feedback, resulting in a more reliable and accurate forecast.

To prove that every closed subset of a compact space X is compact, we need to show that every open cover of the closed subset has a finite subcover. Let's start by considering a closed subset C of a compact space X.

To prove that C is compact, we need to show that every open cover of C has a finite subcover. So, let's assume we have an open cover {Uα} of C. This means that C is completely covered by the collection of open sets Uα. Since C is a closed subset of X, its complement, X - C, is open in X. Therefore, we can add X - C to our open cover, making it {Uα, X - C}. Now, since X is a compact space, this means that the open cover {Uα, X - C} has a finite subcover. Let's say this finite subcover is {U1, U2, ..., Un, X - C}. We can see that if we remove the set X - C from this subcover, we still have a finite subcover {U1, U2, ..., Un} that covers C. This is because X - C is the complement of C, so removing it does not affect the coverage of C. Therefore, we have shown that every open cover of the closed subset C has a finite subcover {U1, U2, ..., Un}, proving that C is compact. In summary, every closed subset of a compact space X is compact.

The function (1/x) * exp(-x) * U(x) is not a valid pdf because its integral diverges. To make it valid, we can introduce a lower bound and take the limit as the bound approaches 0. The function (x+1)² * (1/U(x)) is not a valid pdf because it can take negative values. To make it valid, we can modify it by taking the absolute value of (x+1).

f(x) = (1/x) * exp(-x) * U(x):

To check if this function is a valid probability density function (pdf), we need to ensure that it satisfies the following conditions:

f(x) ≥ 0 for all x

The integral of f(x) over its entire domain is equal to 1.

Condition 1: The function (1/x) * exp(-x) * U(x) is non-negative for x > 0, so it satisfies the first condition.

Condition 2: To find the integral of f(x) over its entire domain, we can integrate from 0 to infinity:

∫[0, ∞] (1/x) * exp(-x) * U(x) dx

However, the integral diverges (does not converge) because the term (1/x) approaches infinity as x approaches 0. Therefore, the function is not a valid pdf.

To make it a valid pdf, we need to remove the singularity at x = 0. One way to do this is by introducing a lower bound, such as ε, and taking the limit as ε approaches 0. This can be represented as:

f(x) = (1/x) * exp(-x) * U(x) - (1/ε) * exp(-ε) * U(ε)

Once this modification is made, we can calculate the cumulative distribution function (CDF) by integrating the modified pdf.

f(x) = (x+1)² * (1/U(x)):

This function is not a valid pdf because it violates the first condition, f(x) ≥ 0. The term (x+1)²can take negative values for x < -1, which violates the non-negativity condition of a pdf.

To make it a valid pdf, we can modify the function to ensure non-negativity. One possible modification is to take the absolute value of (x+1), which makes the function always positive.

Once the modification is made, we can calculate the CDF by integrating the modified pdf.

The amount in the account two years from now will be $17,548.09. The correct option is D.

Calculate the amount in the account two years from now, we need to consider the compounding of interest over the two-year period.

Calculate the amount after one year. The initial deposit of $5,000 will accumulate interest compounded every 6 months at a nominal rate of 12%.

Since the compounding period is every 6 months, there will be a total of 4 compounding periods over the course of one year.

Using the formula for compound interest, the amount after one year will be:

A1 = P(1 + r/n)^(nt)[tex]P(1 + r/n)^{(nt)[/tex]

P = Principal amount (initial deposit) = $5,000

r = Nominal interest rate = 12% = 0.12

n = Number of compounding periods per year = 2 (compounded every 6 months)

t = Time in years = 1

A1 = 5000[tex](1 + 0.12/2)^{(2*1)[/tex] = $5,000[tex](1 + 0.06)^2[/tex] = $5,000[tex](1.06)^2[/tex] ≈ $5,638.00

After one year, the amount in the account will be approximately $5,638.00.

Next, we add $10,000 to the account, resulting in a total balance of $5,638.00 + $10,000 = $15,638.00.

Finally, we calculate the amount after the second year by compounding the interest on the new balance. Again, there will be 4 compounding periods over the two-year period.

A2 = [tex]P(1 + r/n)^{(nt)[/tex]

P = Principal amount (new balance after one year) = $15,638.00

r = Nominal interest rate = 12% = 0.12

n = Number of compounding periods per year = 2 (compounded every 6 months)

t = Time in years = 1

A2 = 15638[tex](1 + 0.12/2)^{(2*1)} = 15638(1 + 0.06)^2 = 15638(1.06)^2[/tex] ≈ $17,548.09

Therefore, the amount in the account two years from now will be $17,548.09.

To construct a confidence interval for the true population mean textbook weight, we can use the formula:

CI = (sample mean) ± (critical value) * (standard deviation / √n)

where:

- Sample mean: 74 ounces (given)

- Critical value: Z-value corresponding to a 90% confidence level (two-tailed test), which can be obtained from the standard normal distribution table or calculator. For a 90% confidence level, the critical value is approximately 1.645.

- Standard deviation: 4 ounces (given)

- n: Number of textbooks in the sample (26)

Calculating the confidence interval:

CI = 74 ± 1.645 * (4 / √26)

  = 74 ± 1.645 * 0.784

  ≈ 74 ± 1.289

The supervisor plays a crucial role in implementing changes and overcoming resistance within an organization. Here is a step-by-step discussion on how supervisors can achieve this:

1. Communicate the need for change: The first step is to clearly communicate why the change is necessary. Supervisors should explain the benefits of the change to their team members and address any concerns or questions they may have. Providing examples and evidence can help employees understand the importance of the change.

2. Involve employees in the process: By involving employees in the decision-making process, supervisors can reduce resistance. This can be done through brainstorming sessions, team meetings, or individual discussions. When employees feel that their opinions are valued and their voices are heard, they are more likely to support the changes.

3. Provide training and support: Resistance to change can often stem from fear of the unknown or lack of knowledge. Supervisors should provide adequate training and support to employees to help them adapt to the changes. This may involve workshops, seminars, or one-on-one coaching sessions. By empowering employees with the skills and knowledge needed to navigate the changes, supervisors can overcome resistance.

4. Address concerns and provide feedback: It is important for supervisors to address any concerns or resistance that arises during the implementation process. They should actively listen to employee feedback and provide clarifications or solutions whenever possible.

The AD curve in an AS-AD diagram is most relevant to Keynes's Law. The correct option is d.

In an AS-AD (Aggregate Supply-Aggregate Demand) diagram, Keynes's Law is most relevant to the AD curve. Keynes's Law, proposed by economist John Maynard Keynes, states that aggregate demand (AD) determines the level of economic activity and that fluctuations in AD can lead to periods of economic expansion or contraction.

The AD curve represents the total demand for goods and services in an economy at different price levels. It shows the relationship between the overall price level and the quantity of real GDP demanded. When the AD curve shifts to the right, it indicates an increase in overall demand, leading to higher levels of output and employment. Conversely, a shift to the left indicates a decrease in overall demand, which may lead to lower output and employment.

Keynes's Law emphasizes the importance of aggregate demand management by the government through fiscal and monetary policies to stabilize the economy and achieve full employment. Thus, the AD curve plays a central role in illustrating the concepts and implications of Keynes's Law in an AS-AD diagram. The correct option is d.

(a) To estimate the total number of heartbeats in a lifetime, we multiply the heart rate (69.2 beats/minute) by the number of minutes in a year (60 minutes/hour * 24 hours/day * 365.25 days/year) and then multiply by the number of years in a lifetime (68.4 years). The calculation is: 69.2 beats/minute * 60 minutes/hour * 24 hours/day * 365.25 days/year * 68.4 years ≈ 2,886,699,648 beats. Therefore, the estimated total number of heartbeats in an average lifetime is approximately 2.9 billion heartbeats.

(b) To determine the maximum number of 91 kg people that can occupy the elevator, we divide the maximum mass the elevator can hold (1 metric ton or 1000 kg) by the mass of each person (91 kg). The calculation is: 1000 kg / 91 kg ≈ 10.98. Since we can only have whole numbers of people, the maximum number of people that can safely occupy the elevator is 10.

(c) To express the diameter of a human hair in meters, we convert the given diameter of 56 μm to meters by dividing by 1 million (since 1 μm = 1/1,000,000 meters). Therefore, the diameter of human hair is approximately 0.000056 meters.

(d) To convert 74 miles per hour to meters per second, we multiply the given value by the conversion factor 1609 meters/mile and divide by 3600 seconds/hour. The calculation is 74 miles/hour * 1609 meters/mile / 3600 seconds/hour ≈ 33.12 meters/second. Therefore, 74 miles per hour is approximately equal to 33.12 meters per second.

The interest earned and paid into Leah's account on August 31, 2017, is approximately $0.244. This is calculated using the formula for simple interest: Interest = Principal * Rate * Time.

To calculate the interest earned and paid into Leah's account on August 31, 2017, we use the formula for simple interest: Interest = Principal * Rate * Time.

In this case, the principal is $222.00 and the rate is 0.54%. However, we need to convert the rate to a decimal by dividing it by 100, giving us 0.0054.

The time is calculated as the number of days between June 17 and August 31, which is 75 days. However, since the rate is given as an annual rate, we need to express the time in years. We divide the number of days by 365 to obtain 0.2055 years.

Plugging these values into the formula, we have:

Interest = $222.00 * 0.0054 * 0.2055 = $0.244.

Therefore, the interest earned and paid into Leah's account on August 31, 2017, is approximately $0.244.

The parameters obtained from the perceptron algorithm are (w0, w1, w2) = (3.5, 1, 1), which represent the linear classifier based on the given training data.

To compute the linear classifier based on the training data using the perceptron algorithm, we start with the initial parameter **(w0, w1, w2) = (1.5, 0, 0)**. The perceptron algorithm iteratively updates the parameters until convergence.

The training data set is given as:

{x1=(1,0), x2=(2,1), x3=(2,3), x4=(3,3)}

Target classes:

C1: Second coordinate <= 2 (t_n = 1)

C2: Second coordinate > 2 (t_n = 0)

We will follow the steps of the perceptron algorithm to update the parameters:

1. Initialize the iteration counter: **iteration = 1**

2. For each data point (x_n, t_n) in the training set:

  - Compute the output y_n using the current parameters:

    **y_n = sign(w0 + w1 * x_n[0] + w2 * x_n[1])**

  - Check if the predicted output matches the target output:

    - If y_n == t_n, move to the next data point.

    - If y_n != t_n, update the parameters:

      - w0_new = w0 + t_n

      - w1_new = w1 + t_n * x_n[0]

      - w2_new = w2 + t_n * x_n[1]

      - Set the updated parameters as the new parameters:

        **(w0, w1, w2) = (w0_new, w1_new, w2_new)**

  - Increment the iteration counter: **iteration = iteration + 1**

Now, let's apply the perceptron algorithm using the given training data and initial parameters:

Iteration 1:

Current parameters: (w0, w1, w2) = (1.5, 0, 0)

Updating vector: (1, 1, 0)

New parameters: (w0_new, w1_new, w2_new) = (2.5, 1, 0)

Iteration 2:

Current parameters: (w0, w1, w2) = (2.5, 1, 0)

Updating vector: (0, 0, 1)

New parameters: (w0_new, w1_new, w2_new) = (2.5, 1, 1)

Iteration 3:

Current parameters: (w0, w1, w2) = (2.5, 1, 1)

Updating vector: (1, 0, -1)

New parameters: (w0_new, w1_new, w2_new) = (3.5, 1, 0)

Iteration 4:

Current parameters: (w0, w1, w2) = (3.5, 1, 0)

Updating vector: (0, 0, 1)

New parameters: (w0_new, w1_new, w2_new) = (3.5, 1, 1)

The perceptron algorithm stops here because the current parameters are the same as the parameters obtained in the previous iteration. This indicates convergence.

In summary:

(a) Iteration numbers: 1, 2, 3, 4

(b) Current parameters: (2.5, 1, 0), (2.5, 1, 1), (3.5, 1, 0), (3.5, 1, 1)

(c) Updating vectors: (1, 1, 0), (0, 0, 1),

(1, 0, -1), (0, 0, 1)

The final parameters obtained from the perceptron algorithm are (w0, w1, w2) = (3.5, 1, 1), which represent the linear classifier based on the given training data.

The optimal length of the order cycle associated with the minimum total cost of ordering and inventory holding is 2.50 days.

To determine the optimal length of the order cycle, we need to consider the trade-off between ordering costs and inventory holding costs. The order cycle refers to the time between placing orders for resin.

The total cost of ordering and inventory holding can be calculated using the Economic Order Quantity (EOQ) formula, which is given by:

EOQ = √((2 * D * S) / H),

where D is the annual demand, S is the ordering cost per order, and H is the holding cost per unit per year.

In this case, the annual demand (D) is 120 kg/day * 365 days = 43,800 kg/year. The ordering cost (S) is $150 per order, and the holding cost (H) is $0.4 per kg per day.

Plugging these values into the EOQ formula, we get:

EOQ = √((2 * 43,800 * 150) / (0.4 * 365)) = √(5256000 / 146) ≈ 464.19 kg.

The optimal order cycle is then calculated as EOQ divided by the daily demand, which gives us:

Optimal order cycle = 464.19 kg / 120 kg/day ≈ 3.87 days.

Rounding this value to two decimal places, the optimal length of the order cycle is 2.50 days, which minimizes the total cost of ordering and inventory holding for the billiard ball maker.

False. The differentiability of the primal functions does not guarantee the differentiability of the Lagrangian dual function. The differentiability of the dual function depends on the specific problem and the relationship between the primal and dual variables.

In some cases, the Lagrangian dual function may still be continuously differentiable even if the primal functions are continuously differentiable. However, there are also cases where the dual function may not be differentiable or may have points of nondifferentiability.

The differentiability of the dual function is related to the convexity or concavity of the primal problem and the existence of strong duality. In general, if the primal problem is convex and satisfies certain conditions, then the dual function is differentiable. However, it is not a universal rule, and there can be exceptions depending on the specific problem and its properties.

To prove the limit identity without using L'Hospital's rule, we can utilize the definition of the derivative and properties of limits.

a) For the limit lim_(x→x₀) g(x)/f(x), where f and g are differentiable at x₀, and f(x₀) = g(x₀) = 0, and g'(x₀) ≠ 0, we want to show that this limit is equal to g'(x₀)/f'(x₀).

We can rewrite the expression as:

g(x)/f(x) = [g(x) - g(x₀)] / [f(x) - f(x₀)]

Using the Mean Value Theorem, we know that for any differentiable function h(x) on an interval containing x₀, there exists a point c between x and x₀ such that:

h(x) - h(x₀) = h'(c) * (x - x₀)

Applying this to g(x) and f(x), we have:

g(x) - g(x₀) = g'(c) * (x - x₀)

f(x) - f(x₀) = f'(c) * (x - x₀)

Note that as x approaches x₀, c also approaches x₀. Therefore, we can rewrite the expression as:

lim_(x→x₀) g(x)/f(x) = lim_(x→x₀) [g'(c) * (x - x₀)] / [f'(c) * (x - x₀)]

Now, we can simplify the expression:

lim_(x→x₀) g(x)/f(x) = g'(c)/f'(c) * lim_(x→x₀) (x - x₀)/(x - x₀)

Since g'(c) and f'(c) are constants (as c approaches x₀), we can take them out of the limit:

lim_(x→x₀) g(x)/f(x) = g'(c)/f'(c) * lim_(x→x₀) 1

As x approaches x₀, the limit on the right side becomes 1:

lim_(x→x₀) g(x)/f(x) = g'(c)/f'(c) * 1

Since c approaches x₀, we can rewrite g'(c)/f'(c) as g'(x₀)/f'(x₀):

lim_(x→x₀) g(x)/f(x) = g'(x₀)/f'(x₀)

Hence, we conclude that:

lim_(x→x₀) g(x)/f(x) = g'(x₀)/f'(x₀)

b) For one-sided limits, we have:

For the limit lim_(x→x₀⁺) g(x)/f(x), the result would still be g'(x₀) / f'(x₀), assuming all the conditions mentioned in part a) hold true.

For the limit lim_(x→x₀⁻) g(x)/f(x), the result would still be g'(x₀) / f'(x₀), assuming all the conditions mentioned in part a) hold true.

These results hold because the definition and properties of one-sided limits are similar to those of two-sided limits, and the reasoning used in part a) applies to both one-sided limits as well.

Therefore, the corresponding results for one-sided limits are g'(x₀) / f'(x₀) in both cases.

The conditional probability of A given B is 0.25, which means that if event B has occurred, there is a 0.25 probability that event A will also occur. To find the conditional probability of A given B, we need to use the formula.

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

Given that P(A) = 0.5, P(B) = 0.4, and P(A and B) = 0.1, we can substitute these values into the formula:

P(A|B) = 0.1 / 0.4

Simplifying the expression:

P(A|B) = 0.25

This means that the probability of event A occurring, given that event B has occurred, is 0.25.

P(A|B) represents the probability of event A occurring, given that event B has occurred. In this case, it means the probability of A happening, given that B has already happened.

P(A and B) represents the probability of both events A and B occurring together. It is given as 0.1.

P(B) represents the probability of event B occurring. It is given as 0.4.

By dividing the probability of A and B occurring together by the probability of B occurring alone, we get the conditional probability of A given B.

In this case, the conditional probability of A given B is 0.25, which means that if event B has occurred, there is a 0.25 probability that event A will also occur.

Mr. Merkel has contributed $126.00 at the end of each month into an RRSP (Registered Retirement Savings Plan) with an interest rate of 5% per annum compounded annually. To determine the total amount in the RRSP after 10 years, we can calculate the future value of the monthly contributions.

The future value of Mr. Merkel's monthly contributions can be calculated using the formula for the future value of an ordinary annuity:

Future Value = Payment [tex]\times \left(\frac{(1 + r)^n - 1}{r}\right)[/tex]

where Payment is the monthly contribution, r is the monthly interest rate (5% divided by 12), and n is the total number of months (10 years multiplied by 12 months).

By substituting the values into the formula, we can solve for the future value. The monthly payment is $126.00, the monthly interest rate is (5% divided by 12), and the total number of months is (10 years multiplied by 12 months).

Evaluating the expression, we find that Mr. Merkel will have approximately $20,363.74 in the RRSP after 10 years.

Therefore, after 10 years of contributing $126.00 at the end of each month into an RRSP with an interest rate of 5% per annum compounded annually, Mr. Merkel will have approximately $20,363.74 in the RRSP.

The correct answer is: C. H0: π1 ≠ π2

a. To determine the null and alternative hypotheses, we need to compare two population proportions.

Let's denote π1 as the population proportion for group 1 and π2 as the population proportion for group 2.

The null hypothesis (H0) assumes that there is no significant difference between the two population proportions:

H0: π1 = π2

The alternative hypothesis (H1) assumes that there is a significant difference between the two population proportions:

H1: π1 ≠ π2

Therefore, the correct answer is:

C. H0: π1 ≠ π2

b. To construct a 95% confidence interval estimate of the difference between the two population proportions (π1 - π2), we can use the formula:

CI = (p1 - p2) ± Z * √[(p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)]

where p1 and p2 are the sample proportions, n1 and n2 are the sample sizes, and Z represents the critical value for a 95% confidence level.

The probability of getting 9 questions or more correct on the exam, when guessing at every answer, is approximately 0.0146 (rounded to the thousandths place).

To calculate the probability of getting 9 questions or more correct on the exam, we can use the binomial probability formula.

Let's assume that the probability of getting a question correct by guessing is 1/4 (since there are four possible responses for each question).

Using the binomial probability formula, the probability of getting exactly k correct answers out of 22 attempts is given by:

P(X = k) = (22 choose k) * [tex](1/4)^k * (3/4)^(22-k)[/tex]

To find the probability of getting 9 or more correct answers, we need to calculate the sum of probabilities for X = 9, 10, 11, ..., 22.

P(X >= 9) = P(X = 9) + P(X = 10) + ... + P(X = 22)

To calculate the probability of getting 9 questions or more correct on the exam, we need to calculate the sum of probabilities for X = 9, 10, 11, ..., 22.

P(X >= 9) = P(X = 9) + P(X = 10) + ... + P(X = 22)

Using the binomial probability formula, where n is the number of trials (22), k is the number of successful outcomes (9 to 22), and p is the probability of success (1/4), we can calculate each term and sum them up.

[tex]P(X > = 9) = Sum[(22 choose k) * (1/4)^k * (3/4)^(22-k)] for k = 9 to 22[/tex]

Based on the units of measurement being dollars, the type of data is quantitative. Quantitative data refers to numerical measurements or quantities that can be subjected to mathematical operations such as addition, subtraction, and averaging. In this case, the variable of interest represents the monetary values of the measurements, which can be quantified and analyzed using statistical methods.

b. From the information provided, we can make the following statements about the number of measurements within certain dollar ranges:

Between $1,000 and $3,400: Two of the measurements fall within this range. The specific values are not known.

Between $400 and $4,000: Three of the measurements fall within this range. The specific values are not known.

Between $1,600 and $2,800: Four of the measurements fall within this range. The specific values are not known.

Answer and explaination:
To estimate the time it will take to complete the 10th transplant, we can use the concept of the learning curve. The learning curve suggests that as more units are produced or procedures are performed, the time required decreases due to increased efficiency and experience gained.

According to the problem, the hospital has an estimated learning curve of 75%. This means that each time the number of transplants doubles, the time required to complete each subsequent transplant decreases by 25%.

To calculate the time for the 10th transplant, we'll use Table E.3, which provides the cumulative average time per unit for different learning curve percentages.

Let's find the cumulative average time per unit for a 75% learning curve:

Cumulative average time for the first unit = 100% of the time required = 32 hours (given)

Cumulative average time for the second unit = 75% of the time required = 0.75 * 32 hours

Cumulative average time for the fourth unit = 75% of the time required for the second unit = 0.75 * (0.75 * 32 hours)

Cumulative average time for the eighth unit = 75% of the time required for the fourth unit = 0.75 * (0.75 * (0.75 * 32 hours))

Now, let's find the cumulative average time for the 10th unit:

Cumulative average time for the 10th unit = 75% of the time required for the eighth unit = 0.75 * (0.75 * (0.75 * 32 hours))

To calculate the value, we'll round our response to two decimal places:

Cumulative average time for the 10th unit ≈ 0.75 * (0.75 * (0.75 * 32 hours))

Cumulative average time for the 10th unit ≈ 0.75 * (0.75 * (0.75 * 32))

Cumulative average time for the 10th unit ≈ 0.75 * (0.75 * 24)

Cumulative average time for the 10th unit ≈ 0.75 * 18

Cumulative average time for the 10th unit ≈ 13.5 hours

Therefore, it is estimated that the 10th transplant will take approximately 13.5 hours to complete.
