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.

A library contains only paperback and hardback books. If the ratio of paperback books to the total number of books is 3 to 5, which statement must be true? The ratio of paperback books to hardback books is 2 to 3. The ratio of paperback books to hardback books is 2 to 3. The ratio of paperback books to hardback books is 3 to 2. The ratio of paperback books to hardback books is 3 to 2. There are exactly 2 paperback books in the library. There are exactly 2 paperback books in the library. There are exactly 8 hardback books in the library. There are exactly 8 hardback books in the library.

Answers

Answer:

A library contains only paperback and hardback books. If the ratio of paperback books to the total number of books is 3 to 5, the true statement is:

The ratio of paperback books to hardback books is 3 to 2.

Step-by-step explanation:

The number of books in the library = 5

The number of paperback books in the library = 3

Therefore, the number of hardback books in the library = 2 (5 - 3)

Then, the relationship between the paperback books and the hardback books in the library can be expressed as a ratio of 3:2.  This still gives the sum of the ratios as 5, which is the total number of books in the library, including paperback and hardback books.

Final answer:

The correct statement is that the ratio of paperback to hardback books is 3:2. The ratios provided do not indicate the exact quantity of books in the library.

Explanation:

The ratio of paperbacks to the total number of books is 3:5. This means that for every 5 books, 3 are paperbacks and therefore, the remaining 2 must be hardbacks. Hence the ratio of paperback to hardback books is actually 3:2, not 2:3.

Note that the ratios given do not indicate the exact number of books. Therefore, we cannot confidently say that there are exactly 2 paperback books or exactly 8 hardback books in the library.

Furthermore, it was found that actually of the components given a quality score A failed, of the components given a quality score B failed, and of the components given a quality score C failed. 11-A. What is the probability that a randomly selected component is NOT failed and received a quality score B

Answers

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In the given question some of the data is missing so, its correct question is defined in the attached file please find it.

Let

A is quality score of A

B is quality score of B

C is quality score of C

\to P[A] =0.55\n\n\to P[B] =0.28\n\n\to P[C] =0.17\n

Let F is a value of the content so, the value is:

\to P[(F)/(A)] =0.15\n\n\to P[(F)/(B)] =0.12\n\n\to P[(F)/(C)] =0.14\n

Now, we calculate the tooling value:

\to p[(C)/(F)]

using the baues therom:

\to p[(C)/(F)] = (p[C] * p[(F)/(C) ])/(p[A] * p[(F)/(A)] + p[B] * p[(F)/(B)]+p[C] * p[(F)/(C)] )  

            = ( 0.17 * 0.14 )/(0.55 * 0.15 + 0.28 * 0.12 + 0.17 * 0.14 ) \n\n= (0.0238)/(0.0825 + 0.0336 + 0.0238) \n\n= (0.0238)/(0.1399) \n\n=0.1701
