Answer:
38.46%
Step-by-step explanation:
There are 91 students and 35 of them received a score of 90 or above.
So, there are 35/91 students with an A grade.
The probability to pick a random student that would be the same proportion that those who got the right score, so 35 / 91 = 0.3846 or 38.46%
38.46% of chances to pick someone who got an A (90 score or above), and, the opposite, 61.54% of chances to pick someone who didn't get an A. That's a strong class!
first you divide 48 by 4
48 ÷ 4 = 12
So each cake will need to be cut into 12 pieces
the answer 
and 12 pieces
The solution is x=-3, y=1, z=-1
