Answer:
50/96
Step-by-step explanation:
I assume the table is:
Even numbers are 2, 4, and 6. The total number of times she rolled an even number is 13 + 17 + 20 = 50.
So the probability is 50/96.
It would shift up, that is the anwser
x | y
10 1 = 1/2 (10) -4=5-5= 1
-2 -5 = 1/2(-2)-4=-1-4= -5
4 -2 = 1/2(4)-4=2-4= -2
-8 -8 = 1/2(-8)-4=-4-4= -8
Answer: x^2-2x-1
0=x^2+2x+1
x^2-2x-1
864 cards
72 cards per set times 15 sets = 1080 cards - 216 cards he already has =864 cards
