A few years ago Visa Card USA studied how frequently consumers use debit and credit cards in making purchases. The results of the study indicated that the probability that a consumer is 18 to 24 years old and uses a Visa Card when making a purchase is 0.0703 and the probability that a consumer is older than 24 and uses a Visa card when making a purchase is 0.2997. Also, the probability that a consumer is 18 to 24 years old is 0.14. (Assume that Visa customers are either 18-24 years old or older than 24).1. What is the probability that a randomly selected consumer who is 18 to 24 years old uses a Visa card for purchases?2. What is the probability that a randomly selected consumer uses a Visa card for purchases given that he or she is older than 24?

1. P=0.502

2. P=0.348

Step-by-step explanation:

1) What is the probability that a randomly selected consumer who is 18 to 24 years old uses a Visa card for purchases?

The probability is equal to the ratio between the probability that is 18-24 and uses Visa and the probability of being 18-24.

2) What is the probability that a randomly selected consumer uses a Visa card for purchases given that he or she is older than 24?

Its the same analysis as the previous question but with >24yo segment.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

the answer would be c:   ax + b = ax + c
