Hello! :)
P (a or b) means
P (a+b)
So the blue side and the red side of the diagram have students so add them up:
3+2=5
Then the ratio
blue and red/total number of students
5/10
(10 students)
So simplify:
1/2
Hope I helped and answered in time!
Good luck!

Hope this helps.
8x^2 +13x -6 =(8x-3)(x+2)
y = x^2 + 2x...eqn 1
y = 3x + 20...eqn 2
subst for y in eqn 1...
=> x^2 +2x = 3x +20
=> x^2 - x - 20 =0
=> (x-5) (x+4) =0
=> x = 5 or -4
for x =5, y = 35 (sub for x in eqn 1 or 2)
for x = -4, y = 8 (sub for x in eqn 1 or 2)
Answer:
"simplify" it
Step-by-step explanation:
To convert from vertex form to standard form for a quadratic, eliminate parentheses and collect terms. In short, "simplify" it.
