We need to purchase to fullfil the inventory for this amount of units.
<u>Now we have to calculate each component:</u>

Next, we multply the purchase requirement per amount per tpye of unit. Once we got total quantity me multiply by the cost.
<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:
comprehensive
Explanation:
Comprehensive listening refers basically to interpreting the meaning of the words that you are reading. I guess most reading should be considered comprehensive, or at least I hope so. It involves trying to understand the message that is written and that includes the basic ideas or concepts.
<h2>collecting evidence to answer a question</h2><h2>researching past events</h2><h2>studying evidence to solve a problem</h2><h2>finding out where, when, and why an event happened</h2>
Explanation:
determining who is responsible for a crime: History does not much speak or research about crime. Only detectives will do research on crime. This option is invalid.
collecting evidence to answer a question:
Historians collects evidence to prove the past where as detectives collect evidence to prove the crime
researching past events
Past events are researched to find out the history by the historians, and detectives research the past crime
finding out where, when, and why an event happened: Historians finds details to register the history for future use and detectives find out the place, date and reason for crime.
studying evidence to solve a problem
Historians study evidence to prove the history and detective study to prove the crime
