Answer:
The answer to this question is a= µ=60/12=5 students/min
Explanation:
Solution
Given that:
λ=4 students / min
The Waiting time in Queue= λ /µ(µ- λ )==4/(5*(5-4))=0.8 min
The Number of students in the line L(q)= λ *W(q)= 4*.8= 3.2 students
TheNumber of students in the system L(q)= λ /(µ- λ )=4/(5-40=4 students
Then,
The Probability of system to be empty= P0= 1-P= 1-0.8= 0.2
Now,
If the management decides to add one more cashier with the same efficiency then we have
µ= 6 sec/student= 10 students/min.
so,
P= λ /µ =4/10=0.4
Now,
The probability that cafeteria is empty= P0= 1-0.4= 0.6
If we look at the above system traits, it is clear that the line is not empty and the students have to standby for 0.8 in the queue waiting to place their order and have it, also on an average there are 3.2 students in the queue and in the entry cafeteria there are 4 students who are waiting to be served.
If the management decides to hire one more cashier with the same work rate or ability, then the probability of the cafeteria being free moves higher from 0.2 to 0.6 so it suggests that the management must hire one additional cashier.
Answer:
The answer to this question is option B. Deflation means that the price level is failing, whereas with inflation overall prices are rising
Explanation:
Inflation is an increase in the general prices of goods and services in an economy on the other hand, deflation is the general decline in prices for goods and services, indicated by an inflation rate that falls below zero percent.
Hence the answer is option B. Deflation means that the price level is failing, whereas with inflation overall prices are rising
Answer:
Annual deposit= $1,192,568.62
Explanation:
Giving the following formula:
Future Value= $15,000,000
Number of periods= 10 years
Interest rate= 5% compounded annually
<u>To calculate the annual deposit, we need to use the following formula:</u>
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (15,000,000*0.05) / [(1.05^10) - 1]
A= $1,192,568.62
Answer:
If an economist argues that everyone gains from trade, the following reasoning is most likely underlying her argument:
- Production according to the principle of comparative advantage lowers overall costs and therefore allows both countries to have a higher standard of living.
Explanation:
- The comparative advantage refer to the situation in which an individual, company or a country offers its services and products at a lower rate as compared to its competitor. This leads to trade-off as you have to comprise for the gain of something.
- This comparative advantage also increase the dependencies of nations or companies on each other.
- For example, England and Portugal has benefited from this comparative advantage concept as England get the wine at lower cost from Portugal and Portugal also get earning by selling this wine to England.
Since there is no debt, all the capital that the company raises is in the form of common equity.
Since there is only equity (meaning the firm is a fully equity firm), the weighted average cost of capital (WACC) is nothing but the cost of equity
In this case the WACC represents the cost of equity
Therefore, cost of equity = WACC = 8%
