What is the difference in longitude between P (lat. 50°N. long. 50°W) and Q (lat.50°N, long. 150°W)?
300o
200o
130o
100o
30o
Correct answer is D
Let \(\theta\) be the angular difference between P (50°N. 50°W), and Q (50°N, 150°W),
\(\theta\) = 150° - 50° =100°
4.0m
5.8m
7.1m
8.1m
18.5m
Correct answer is A

If cos 60° = 1/2, which of the following angle has cosine of -1/2?
30o
120o
150o
210o
300o
Correct answer is B
cos 60° = 1/2, cos(180° - 60°) = -1/2
cos120° = -1/2

Correct answer is C
There are 20 students. Hence, the median is found by the average of the 10th and 11th score.
= \(\frac{3 + 3}{2}\)
= 3
1.75

2.5
2.75
3
Correct answer is D
| Score | 0 | 1 | 2 | 3 | 4 | 5 | Total |
| Freq | 2 | 3 | 4 | 2 | 7 | 2 | 20 |
| \(fx\) | 0 | 3 | 8 | 6 | 28 | 10 | 55 |
\(\bar{x} = \frac{\sum fx}{\sum f}\)
= \(\frac{55}{20}\)
= \(2.75\)
