In a class of 26 students, 14 are taking German and 9 are taking Spanish. Of the students studying German or Spanish, 6 are taking both courses. How many students are not enrolled in either course?
| 12 | |
| 9 | |
| 14 | |
| 20 |
The number of students taking German or Spanish is 14 + 9 = 23. Of that group of 23, 6 are taking both languages so they've been counted twice (once in the German group and once in the Spanish group). Subtracting them out leaves 23 - 6 = 17 who are taking at least one language. 26 - 17 = 9 students who are not taking either language.

If a mayor is elected with 84% of the votes cast and 76% of a town's 12,000 voters cast a vote, how many votes did the mayor receive?
| 5,928 | |
| 4,742 | |
| 6,202 | |
| 7,661 |
If 76% of the town's 12,000 voters cast ballots the number of votes cast is:
(\( \frac{76}{100} \)) x 12,000 = \( \frac{912,000}{100} \) = 9,120
The mayor got 84% of the votes cast which is:
(\( \frac{84}{100} \)) x 9,120 = \( \frac{766,080}{100} \) = 7,661 votes.
Find the average of the following numbers: 16, 10, 17, 9.
| 13 | |
| 59 | |
| 18 | |
| 8 |
To find the average of these 4 numbers add them together then divide by 4:
\( \frac{16 + 10 + 17 + 9}{4} \) = \( \frac{52}{4} \) = 13
Diane scored 87% on her final exam. If each question was worth 2 points and there were 120 possible points on the exam, how many questions did Diane answer correctly?
| 52 | |
| 48 | |
| 41 | |
| 60 |
Diane scored 87% on the test meaning she earned 87% of the possible points on the test. There were 120 possible points on the test so she earned 120 x 0.87 = 104 points. Each question is worth 2 points so she got \( \frac{104}{2} \) = 52 questions right.
