Question

The table shows the marks obtained by 16 students in a class for a Mathematics test.

3 18 20 19 14 9 8 13 16 19 14 10 14 10 12 10

(ii) If 50% of the students passed the test, find the passing mark for the test.

The answer is 14 but I don't get how, please solve it I'll mark you as bra¡nl¡est and f0ll0w you. ​

Answer 1

Answer:

Total students are 16

so, 50% of the students = 16 × 50/100

= 8 students.

only 8 students passed the test.

Step-by-step explanation:

Now, arrange the marks in descending order and the first 8 students are the ones who passed.

20, 19, 18, 16, 16, 14, 14, 14, 13, 12, 10, 10, 10, 9, 8, 3

(20 to 14) are the first eight and the ones who passed, therefore 14 must be the passing marks.

Hope it makes sense now.
