Tobias has 12 coins in his pocket. Of these coins, 8 were made in the year 2000, and 4 were made in the year 2005. Tobias randomly selects one coin from his pocket and, without replacing it, selects another coin from his pocket. What is the probability that both coins he selects were made in the year 2000?

Answers

Answer 1

Answer: the total coins are 12, 8 are from year 2000.
So the probability of having the first coin from year 2000 is 8 out of 12 = 8/12 = 0.666 = 66.7%
For the second, would be 7 coins from 2000 out of 11 total, that is 7/11 = 0.636 = 63.6%
and the total probability is the multiplications of them both:
total probability = 0.666*0.636 = 0.424 = 42.4%
thatt is the probability

Find an explicit rule for the nth term of a geometric sequence where the second and fifth terms are -36 and 2304, respectively.

Answers

When we find a geometric sequence using the first and second terms, what we do is divide the second by the first to find a "common ratio," the number you multiply by to get to the next term.

In this case, we only have the second and fifth terms. From the second to the fifth term, we've multiplied by that common ratio three times.
What we can do is divide the fifth by the second and then take the cube root to find our common ratio.

$2304/-36=-64\n\sqrt[3]-64=\boxed{-4}$

Now we know we're multiplying by -4 each time, let's find the first term.

The opposite of multiplying by -4 would be dividing by -4. We work back from our second term -36 to find that the first term would be 9.

For each sucessive term, we then multiply by -4.

Our equation is $a_n=9*-4^((n-1))$

A jar contains jelly beans that are red, yellow, blue, and purple. Several people reach in and grab handfuls of jelly beans, then collectively tally the number of each color: 15 red, 20 yellow, 12 blue, and 8 purple. If someone pulls out 22 jelly beans, about how many would you expect to be yellow?

Answers

1) calculate percentage of yellow jelly beans from original capture
20 / (15+20+12+8) = 4/11 or 36.364%
2) apply percentage to new amount
4/11 *22 = 8 beans

Answer:

the answer is 8.
