Po = 0.5385, Lq = 0.0593 boats, Wq = 0.5930 minutes, W = 6.5930 minutes.
<u>Explanation:</u>
The problem is that of Multiple-server Queuing Model.
Number of servers, M = 2.
Arrival rate,
= 6 boats per hour.
Service rate,
= 10 boats per hour.
Probability of zero boats in the system,
= 0.5385
<u>Average number of boats waiting in line for service:</u>
Lq =![[\lambda.\mu.( \lambda / \mu )M / {(M – 1)! (M. \mu – \lambda )2}] x P0](https://tex.z-dn.net/?f=%5B%5Clambda.%5Cmu.%28%20%5Clambda%20%2F%20%5Cmu%20%29M%20%2F%20%7B%28M%20%E2%80%93%201%29%21%20%28M.%20%5Cmu%20%E2%80%93%20%5Clambda%20%292%7D%5D%20x%20P0)
=
= 0.0593 boats.
The average time a boat will spend waiting for service, Wq = 0.0593 divide by 6 = 0.009883 hours = 0.5930 minutes.
The average time a boat will spend at the dock, W = 0.009883 plus (1 divide 10) = 0.109883 hours = 6.5930 minutes.
The correct answer is obviously, You recognized that it exists, i have no idea what they were smoking when they wrote this question.

Answer:
b) Managerial hubris
Explanation:
Based on the scenario being described within the question it can be said that the term that is often used to describe this would be Managerial hubris. This term refers to the unrealistic belief by managers that believe that they can manage a target firm's assets better than that firm's current management. Which is what is happening in this scenario since the managers at Winter Wonder believe that they can do a better job at managing the Sleds by Bob business better that their current managers.
Answer:
A. What is DeShawn's marginal benefit if he sells a basic detailing package?
- marginal benefit = marginal revenue - marginal cost = $75 - $40 = $35
B. What is the marginal cost of adding the engine detailing to the basic detailing package?
C. Should DeShawn continue to offer the engine detailing service?
- Yes. From an economic point of view, a firm maximizes its accounting profit when marginal revenue = marginal cost, and since DeShawn's marginal cost is still much lower than his marginal revenue, he should continue to offer it. From a marketing point of view, this premium service (it is more expensive) may be something that a certain percent of DeShawn's clients want and if he quitted that service he might lose the clients.
