<span>I would assume that customers arrive at the queue according to the poisson process, and then decide whether to enter the queue or leave as per the rules in the question.
for (a)
I interpret "enter the system" as "join the queue".
The expected time for this will be
E(time until there is a free slot) + E(time for someone to arrive once a slot is free).
Noting that the additional time taken for someone to arrive once a spot is free is independant of the time that the slot became free (memorylessness property of poisson process)
The waiting time of a Poisson(\lambda) is exp(\lambda) with mean \frac{1}{\lambda}
E(\text{Time someone enters the system})=\frac{1}{2\mu} + \frac{1}{\lambda}
Your post suggests you already understand where \frac{1}{2\mu} comes from.</span>
Answer:
ROA = 6.6%
ROE 14.52%
Explanation:
profit margin = net income / sale = 12%
assets turn over = sales / assets = 0.55
equity mutiplier = assets / equity = 2.2
ROE = return on equity = net income / equity
ROA = return on equity = net income / assets
we use the fraction properties to get ROE and ROA
ROA = 6.6%
We apply the same property to get ROE
ROE = 14.52%
The "theoretical" price of one beer goes up for a second or subsequent DUI.
One may cost you up to $8000 dollars in some countries, and the second one may cost even more.
Answer:
$36
Explanation:
Computation for comparable firm 1
Price earning = Share price / Earning per share
= $50 / 5 = $10
Computation for comparable firm 2
Price earning = Share price / Earning per share
= $28 / 2 = $14
Average price earning = (Price earning of firm 1 + Price earning of firm 2) / 2
= ($10 + $14) / 2
= $12
Computation of stock price For STU
Stock price = Average price earning × Earning per share of STU
STU = 12 × ($3 million / $1 million) = $36
