Find the average of the following numbers: 11, 5, 10, 6.
| 5 | |
| 10 | |
| 13 | |
| 8 |
To find the average of these 4 numbers add them together then divide by 4:
\( \frac{11 + 5 + 10 + 6}{4} \) = \( \frac{32}{4} \) = 8
What is the next number in this sequence: 1, 4, 7, 10, 13, __________ ?
| 10 | |
| 18 | |
| 25 | |
| 16 |
The equation for this sequence is:
an = an-1 + 3
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 + 3
a6 = 13 + 3
a6 = 16
What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?
| 31 | |
| 37 | |
| 39 | |
| 36 |
The equation for this sequence is:
an = an-1 + 2(n - 1)
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 + 2(6 - 1)
a6 = 21 + 2(5)
a6 = 31
If there were a total of 200 raffle tickets sold and you bought 18 tickets, what's the probability that you'll win the raffle?
| 15% | |
| 9% | |
| 13% | |
| 3% |
You have 18 out of the total of 200 raffle tickets sold so you have a (\( \frac{18}{200} \)) x 100 = \( \frac{18 \times 100}{200} \) = \( \frac{1800}{200} \) = 9% chance to win the raffle.
