Answer:
Concept: Ordinary Mathematics
- Just a general tip: Zoom away further from the camera to capture the question clearer.
- Calculate the Total: 31 students
- A= 4/31= 13%
- (A+B)/31 = 14/31 = 45%
- Can't see clearly what it says
Answer:
B. This event will not happen.
C. The probability is 0.
Step-by-step explanation:
Only B and C can be answers because there are no green marbles so how can you select a green marble when there aren't any. The probility is 0 which means never going to happen.
M/-5+3=-4.5 -4.5-3=-7.5
m/-5=-7.5 -7.5×-5=37.5
m=37.5
I basically did PEMDAS in reverse... and flipped the signs.
-5^7/-5^2=5^7/5^2= 5^(7-2)=5^5 this is the answer
2x + 9 = 35
-9 -9
2x = 26
x = 13
