Which are considered good credit practices? Check all that apply. Pay less than the minimum amount due. Make payments on or befo
Margaret [11]

Answer:

Make payments on or before the due date; Pay off the full amount with the first monthly statement; Have a plan of how you will repay the money.

Explanation:

Good credit practices will help build your credit.

You must pay at least the minimum amount due each month in order to avoid late fees and derogatory marks on your credit report.  This means the first option is not correct.

Making payments on or before the due date will keep your account in good standing.  This option is correct.

Paying off the full amount with the first monthly statement, while it does not help y

our credit score much, will keep your account in good standing.  This option is correct.

Having a plan of how you will repay the money you borrow is essential before you start borrowing.  This option is correct.

Choosing the credit card with the highest interest rate will cause you to pay more over the lifetime of the balance.  This is not something you want; this option is not correct.

Seventy percent of kids who visit a doctor have a fever and 21% of kids have fever and sore throats . what is the probability th
Neko [114]

The probability that a kid who goes to the doctor has a sore throat given that he has a fever is <u>0.30 or 30%</u>. Computed using conditional probability.

The probability of any event A given that event B has already taken place is found using the formula P(A|B) = P(A ∩ B)/P(B). This is known as conditional probability, where P(A ∩ B) is the probability of events A and B, and P(B) is the probability of event B.

In the question, we are given that 70% of kids who visit a doctor have a fever and 21% of kids have a fever and sore throats.

We are asked to find the probability that a kid who goes to the doctor has a sore throat given that he has a fever.

We suppose the event of going to the doctor while having a fever to be B, and going to a doctor while having a sore throat to be A.

We are given that 70% of kids who visit a doctor have a fever, that is, the probability of event B, P(B) = 70% = 0.7.

We are given that 21% of kids who visit a doctor have a fever and sore throats, that is, the probability of event A and event B, P(A ∩ B) = 21% = 0.21.

We are asked to find the probability that a kid who goes to the doctor has a sore throat given that he has a fever, that is, we are asked to find the conditional probability of event A, when event B has already taken place, that is, P(A|B).

By formula, we know that:

P(A|B) = P(A ∩ B)/P(B) = 0.21/0.70 = 0.30.

Thus, the probability that a kid who goes to the doctor has a sore throat given that he has a fever is <u>0.30 or 30%</u>.
