Answer:
A
Step-by-step explanation:
The mean/average is the sum of all the numbers divided by the number of numbers.
It is given that mean is 4.5 points. <em>At this point, it means that there might be students scoring less than 4.5 and students scoring greater than 4.5 BUT the average comes to be 4.5</em>.
BUT SINCE IT IS GIVEN THAT EACH STUDENT SCORED THE SAME, the only way that this can be true is when EVERY STUDENT SCORES 4.5. This way, the AVERAGE/MEAN will be 4.5
Hence, the correct answer is A.

Answer:
x-3
Step-by-step explanation:
f(x) = 3x-2
g(x) = 2x + 1
(f-g)(x) = 3x-2 - ( 2x+1)
Distribute the minus sign
=3x-2 -2x-1
Combine like terms
= 3x-2x -2-1
=x-3
