First off, it would not be C because there are no guidelines to score too high on a test
Then, D would also be wrong because since he scored high, it doesn't just mean that the test was easy.
Now it comes to the yes or no between A and B, since he is just one of the many students in Trigonometry, it cant be a very accurate representation therefore the answer to the problem would be A
Solution: A. No, because Mark is not representative of the population of the trigonometry class

|x| = |-7| = 7
|y+z| = |8-11| = |-3| = 3

|x|+|y+z| = 7+3 = 10

10
