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

Susan threw away in the garbage an old chair that had been in her family for many years by placing it on the curb with the rest
rewona [7]

Answer:

It belongs to Alma because Susan abandoned it and Alma took possession of it

Explanation:

By common law, Alma is a person who has found an abandoned property and she may claim it. To do this, she has to take some definite steps to show her claim. Alma can claim this abandoned piece of chair by taking it into her house, or by placing a sign on it to show that she now owns it.

If Susan was to take this to court, the court would determine the kind of item and where it was found to determine if Alma has a right to it. But since it was found in a dump site she now has the right to it.
