A voter survey has determined that 20% of the residents of Flaugamuck County own an iPod. Furthermore, 75% of these iPod owners are under 30 years of age, whereas 25% are 30 or older. Only 35% of the people who don't own iPods are under 30 years of age.

What percentage of the residents who are 30 or older own iPods? Or, equivalently, what is the conditional probability that a resident known to be 30 or more years of age will own in iPod? (Give your answer as a percentage correct to two decimal places.)

8.77% probability that a resident known to be 30 or more years of age will own in iPod

Step-by-step explanation:

We use the conditional probability formula to solve this question.

In which

P(B|A) is the probability of B happening when A happens

is the probability of both events happening

P(A) is the probability of event A happening.

In this problem:

Event A: Over 30 years of age.

Event B: Owning an iPod.

Being over 30 years of age:

25% of those 20% who own an iPod.

100-35 = 65% of those 80% who do not own an iPod. So

Being over 30 years of age and owning an iPod:

25% of those 20% who own an iPod. So

8.77% probability that a resident known to be 30 or more years of age will own in iPod

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
