<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:
The correct answer is A. The Mars Climate Orbiter crashed on the surface of Mars because one program output thrust in terms of foot-pounds, and another program expected thrust to be expressed in terms of newtons.
Explanation:
The Mars Climate Orbiter was NASA’s unsuccessful mission to study the Martian climate, part of the Mars Surveyor 98 program. The MCO was created as a satellite-translator for the Mars Polar Lander lander, and after the latter ceased to function, it was supposed to study the Martian climate.
The Mars Climate Orbiter was destroyed when a navigation error caused the probe to be improperly elevated as it entered orbit. The vehicle was destroyed by the friction and stresses in Mars' atmosphere. An investigation showed that some data for the rocket system were calculated in English units (pound-force-second) while the navigation team expected SI units (Newton-second).
Answer:
$64,300
Explanation:
The amount of revenue that Moretti Department store should recognize as revenue in 2021 should be based on the redeemed amount in the year and unused balance:
1. $1,500 were redeemed during 2021

Answer:
$307
Explanation:
The computation of the interest expense is shown below:
= Principal × rate of interest × number of days ÷ (total number of days in a year)
= $80,000 × 6% × (23 days ÷ 360 days)
= $307
The 23 days is taking from July 8 to July 31
We simply applied the simple interest formula by multiplying the principal amount with the rate of interest and the time period
