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

Michael Barry, Attorney, P.C. began the year with total assets of $126,000, liabilities of $74,000, and stockholders’ equity of
goldenfox [79]

Answer:

The expenses can be recorded as follows;

Debit to the expenses of $33,000 and a credit to the cash account of $33,000.

Explanation:

The accounting equation is an equation that tends to balance a company's assets on one side and the sum of its liabilities and shareholders equity on the opposite side of the equation. It form the basis for the double-entry system in accounting that includes an accounts debit and credit. The debit is a sum to an amount that is owed, it is usually listed on the left hand-side of an account while the credit is a listing of a sum that is received usually on the right hand side of an account.

In the case of Michael Barry, the accounting equation;

Assets=liabilities+stockholders equity

Assets=$126,000

Liabilities=$74,000

Stockholders equity=$52,000

liabilities+stockholders equity=74,000+52,000=$126,000

The assets equals the sum of the liabilities and stockholders equity.

To record expenses paid of $33,000;

                            Debit           Credit

Expenses          $33,000

Cash                                       $33,000
