An undergraduate business student has purchased a laptop computer for use during exams. This laptop is perfectly reliable except

for two parts: its microchip, which has a failure rate of one in every twenty hours of operation; and its battery, which has a failure rate of one in every ten hours of operation. Also, on average the battery will wear out in five hours, with a standard deviation of 30 minutes. Assuming that a new battery has just been installed, what is the probability that the laptop will perform reliably during a one-hour exam?

Answer:

probability of a reliable performance = 19/20

Explanation:

If a new battery has just been installed, then the chances of failure are only contributed by the faulty microchip, which has a failure rate of 1 in 20 hours.

Therefore in 1 hour, the probability that the laptop will perform reliably is calculated as follows:

Chances of failure = 1 in 20

20 hours = 1 chance of failure

∴ 1 hour = 1/20 chance of failure

1/20 = 0.05 chance of failure

Now, let us express 0.05 as fraction:

0.05 = 5/100

Therefore in 1 hour, there is a 5 in 100 chances of failure.

But we are asked to find the probability that the laptop will perform reliably. This is simply done by finding the difference between the total chances of occurrence (100)  and the chances of failure (5)

∴ Probability of reliable performance in one hour = (100 - 5) / 100

= 95/100

95/100 = 19/20

Flannery Corporation owns machinery with a book value of $520,000. It is estimated that the machinery will generate future cash
Aleonysh [2.5K]

Answer:

(d)$105,000.

Explanation:

Since the book value is more than the generated future cash flows so book value cannot be recovered. In this case, the generated future cash flows are ignored  

In this scenario, we compare the values between book value and the fair value of machinery, the difference would be the loss on impairment of the asset

In mathematically,  

= Book value of machinery - fair value of machinery

= $520,000 - $415,000

= $105,000

A factory costs $460,000. You forecast that it will produce cash inflows of $150,000 in year 1, $210,000 in year 2, and $360,000
max2010maxim [7]

Answer:

Explanation:

a.Present value of inflows=cash inflow*Present value of discounting factor(rate%,time period)

=150,000/1.12+210,000/1.12^2+360,000/1.12^3

=557580.18

NPV=Present value of inflows-Present value of outflows                  

=557580.18-460,000

=$97580.18(Approx)=Value of factory

b.Hence since net present value is positive;factory is a good investment

(Yes)
