If the exam is worth (only!) 15%, then the class average is worth (100-15)=85%.
The grade will then be 54*0.85+0*0.15= 45.9%
The letter grades (if any) will vary from school to school.
Answer:
3x - 6
Step-by-step explanation:
Segment YB = x + 3
Segment BW = 2x - 9
Add the two segments.
x + 3 + 2x - 9
3x - 6
The diagonal YW is 3x - 6 units long.

Probability
Step-by-step explanation:
Probability of an event is how likely that event is to happen. And it is denoted by letter P and calculated by the formula below:
P(E) = number of possible outcome/number of the total event sample
P(E) = n(E) / n(S)
I believe it would be 3.5? I could be wrong, but inverse variation usually moves by the constant rate of 2.
