Answer:
A. the double coincidence of wants problem.
Explanation:
Trade by barter involves the exchange of goods and services for goods and services without the use of money as a medium of exchange. In barter system, there is what we call double coincidence of wants. This is the economic situation whereby both parties holds what the other wants to buy, so they exchange the goods directly. Here, both parties agrees to buy and sell each other commodities. However, if one of the party is not interested in what the other party is offering, it causes a disruption in the trade. This disruption refers to a drawback in the system like the example described in the question.
Here, Andy couldn't make a deal with Danny even tho he wants what Danny is offering. This is because what Danny isn't interested in what Andy is offering. Thus, the double coincidence of want and barter trade can't occur between the two parties.
Answer:
The correct answer is C
Explanation:
Bank asset is the assets which represent the ownership of the value capable of being converted into cash. So, the reserve which the banks hold or refrain from using will be classified as the asset for the bank. And the deposit made by the customer will be classified as the current liability as the bank allows the customers to use their deposits whenever they want to use.
Therefore, the reserve is a part of bank asset whereas the deposits will not be a part of bank asset.
Complete Question
A waiting line problem has an average of 250 arrivals per eight hour day. Suppose there are several servers, and each has an average service time of 8 minutes. (Assume Poisson arrivals and exponential service times.)
What is the average service rate of a server per hour?
Answer:
7½ arrivals per hour
Explanation:
Given
Arrivals = 250 arrivals per 8 hour day
Service Time of Servers = 8 minutes
The service time of Servers is given as 8 minutes.
This means that; on average, a server will attend to 1 arrival in every 8 minutes.
Calculating this per hour;
Average service rate of a server per hour = Service Rate * 1 hour per hour
Average service rate of a server per hour = 1 arrival per 8 minutes * 1 hour per hour
(1 hour = 60 minutes);
So, we have.
Average service rate of a server per hour = 1/8minutes * 60minutes/hour
= ⅛ * 60 arrivals/hour
= 60/8 arrivals/hour
= 7½ arrivals per hour
