The answer to this question is c I think
Answer:
Step-by-step explanation:
Points are said to be collinear if they all lie on a line .
Let points L , M, N be collinear i.e they all lie on a line .
Consider the following figure :
Given :
LN = 54 units
LM = 31 units
To find : MN
Solution :
Clearly we can see LM + MN and LN coincides each other and we know that two things which coincide are equal to each other .
Therefore , LM + MN = LN
31 + MN = 54
On transposing 31 to RHS , we get MN = 54-31 = 23 units
{ Transposition is basically a process of taking one number from side to the other with the opposite operation }
Step-by-step explanation:
4 administrator are eligible and the student relations committee has only 2 administrator there are C (4,2) ways of choosing the administrators for the student relations committee
similarly for faculty members ways (8,3) and for students C (20,5)
the number of possible committee = 4!/2!2! × 8!/3!5! ×20!/5!15!
= 6 ×56 ×15504
= 5,209,344
