There are 198 boys in the introductory Chinese course
<h3>How to determine the number of boys?</h3>
The given parameters are
Total = 363
Ratio = Boys : Girls = 6 : 5
So, we have
Boys =6/(5 + 6) * total number of students
This gives
Boys = 6/11 * 363
Evaluate
Boys = 198
Hence, there are 198 boys in the introductory Chinese course

Two or more points are said to be collinear if they lie on the same straight line.
Given a straight line XY, with a point P on the straight line between point X and Y, then
XP + PY = XY
From the question, it was given that AB = 7 and BC = 4, so if A, B, C are colinear, then
AB + BC = AC
i.e. 7 + 4 = 11
But, from the equation, AC = 9.
Therefore, points A, B and C are not collinear.
