If there were a total of 200 raffle tickets sold and you bought 6 tickets, what's the probability that you'll win the raffle?
| 1% | |
| 3% | |
| 12% | |
| 17% |
You have 6 out of the total of 200 raffle tickets sold so you have a (\( \frac{6}{200} \)) x 100 = \( \frac{6 \times 100}{200} \) = \( \frac{600}{200} \) = 3% chance to win the raffle.
If a mayor is elected with 67% of the votes cast and 66% of a town's 41,000 voters cast a vote, how many votes did the mayor receive?
| 23,813 | |
| 18,130 | |
| 15,154 | |
| 15,965 |
If 66% of the town's 41,000 voters cast ballots the number of votes cast is:
(\( \frac{66}{100} \)) x 41,000 = \( \frac{2,706,000}{100} \) = 27,060
The mayor got 67% of the votes cast which is:
(\( \frac{67}{100} \)) x 27,060 = \( \frac{1,813,020}{100} \) = 18,130 votes.
Solve for \( \frac{4!}{2!} \)
| \( \frac{1}{210} \) | |
| 12 | |
| \( \frac{1}{7} \) | |
| \( \frac{1}{6} \) |
A factorial is the product of an integer and all the positive integers below it. To solve a fraction featuring factorials, expand the factorials and cancel out like numbers:
\( \frac{4!}{2!} \)
\( \frac{4 \times 3 \times 2 \times 1}{2 \times 1} \)
\( \frac{4 \times 3}{1} \)
\( 4 \times 3 \)
12
What is the next number in this sequence: 1, 9, 17, 25, 33, __________ ?
| 39 | |
| 43 | |
| 47 | |
| 41 |
The equation for this sequence is:
an = an-1 + 8
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 8
a6 = 33 + 8
a6 = 41
Which of these numbers is a factor of 48?
| 48 | |
| 40 | |
| 17 | |
| 6 |
The factors of a number are all positive integers that divide evenly into the number. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.
