Answers

The product of the given expressions is (1/3a). therefore, option (1/3a) is correct.

To find the product of the two expressions:

(а - 3) / (15a) * (5 / (a - 3))

First, notice that (a - 3) appears in both the numerator and the denominator, and these terms will cancel out, leaving:

(5 / 15a)

Now, you can simplify this fraction:

5 / 15a = (1/3a)

So, the product of the given expressions is:

(а - 3) / (15a) * (5 / (a - 3)) = (1/3a)

((a - 3))/(15a)  *  (5)/((a - 3))  =  (5)/(15a)  =  (1)/(3a)

Transactions to a computer database are either new items or changes to previous items. The addition of an item can be completed less than 100 milliseconds 81% of the time, but only 20% of changes to a previous item can be completed in less than this time. If 30% of transactions are changes, what is the probability that a transaction can be completed in less than 100 milliseconds? Round your answer to two decimal places (e.g. 98.76).

Answers

Answer:

There is a 62.7% probability that a transaction can be completed in less than 100 milliseconds.

Step-by-step explanation:

This a probability problem.

We have the following probabilities:

-70% probability that a transaction is an addition of an item.

-30% probability that a transaction is a change to an item

-81% probability that an addition can be completed in less than 100 milliseconds

-20% probability that change can be completed in less than 100 milliseconds

The probability P that a transaction can be completed in less than 100 milliseconds is:

P = P_(1) + P_(2)

In which P_(1) is the probability that the transaction is an addition and it takes less than 100 milliseconds. So

P_(1) = 0.7*0.81 = 0.567

P_(2) is the probability that the transaction is a change and it takes less than 100 milliseconds. So

P_(2) = 0.2*0.3 = 0.06

So

P = P_(1) + P_(2) = 0.567 + 0.06 = 0.627

There is a 62.7% probability that a transaction can be completed in less than 100 milliseconds.
