9 members of a bridal party need transported to a wedding reception but there are only 3 2-passenger taxis available to take them. How many will need to find other transportation?

There are 3 2-passenger taxis available so that's 3 x 2 = 6 total seats. There are 9 people needing transportation leaving 9 - 6 = 3 who will have to find other transportation.
What is \( \frac{-9a^9}{8a^4} \)?
| -1\(\frac{1}{8}\)a5 | |
| -1\(\frac{1}{8}\)a36 | |
| -\(\frac{8}{9}\)a13 | |
| -\(\frac{8}{9}\)a5 |
To divide terms with exponents, the base of both exponents must be the same. In this case they are so divide the coefficients and subtract the exponents:
\( \frac{-9a^9}{8a^4} \)
\( \frac{-9}{8} \) a(9 - 4)
-1\(\frac{1}{8}\)a5

If there were a total of 100 raffle tickets sold and you bought 2 tickets, what's the probability that you'll win the raffle?
| 2% | |
| 7% | |
| 10% | |
| 1% |
You have 2 out of the total of 100 raffle tickets sold so you have a (\( \frac{2}{100} \)) x 100 = \( \frac{2 \times 100}{100} \) = \( \frac{200}{100} \) = 2% chance to win the raffle.
