Sam had the better score
To compare their scores we require to convert them into percentages
Express as a fraction and multiply by 100%
× 100% = 86.7% ( to 1 dec. place )
× 100% = 83.3% ( to 1 dec. place )
Answer:
(2/3)y - (8/3) = x For the first one maybe?
Step-by-step explanation:
1. y = (3/2) x + 4
y - 4 = (3/2) x
(2/3)y - (8/3) = x
2. If output is 2, f(x) = 2.
So, 2 = (3/2) x + 4
-2 = (3/2) x
-4 = 3x
x = -3/4
School A : 12/38 = 0.315 = 31.5%
school B : 9/48 = 0.187 = 18.7%
school C : 10/26 = 0.384 = 38.4%
school D : 8/24 = 0.333 = 33.3%
school C has the greatest percentage
The answer is 43 when you add 29 back to 57 then divide by 2
