so all those quadratics have their parent y = x², which has the graph of a "bowl".
and depending on the coefficient, the bowl is wider or not.
the larger the coefficient, the narrower the bowl, the smaller the coefficient, the wider the bowl.
well, 1/2 is smaller then 2, thus y = (1/2)x² is wider than y = 2x².
The percentage of 15% of 9 is 60% (I think)

Answer:
the answer is 5/33
Step-by-step explanation:
Total marbles = 5 blue + 4 red + 3 yellow = 12
Two marbles are selected, first is blue which gives us :
5/12 --eq 1
Then red marble is selected ( note: one marble is already drawn and not replaced so we have a total of 11 marbles )
The probability of red gave us :
4/11 --eq 2
Now we multiply eq 1 and 2
5/12 x 4/11 = 5/33
