Answer: (9,5)
How I got it: Multiply 3 on the bottom equation. You will get -4x+9y=9 and 3x-9y=-18. Add both equations and you will get -x=-9. So x equals 9. Then substitute 9 into x for any equation. (I did the botto) You will get -3y=-15. So y equals 5 <span />

52 cards / 4 suits = 13 cards of each suit.
Theoretically picking a heart would be 13/52 = 1/4 probability.
Experimentally she picked 15 hearts out of 80 total tries. for a 15/80 = 3/16 probability, which is less than the theoretical probability.
1/4 - 3/16 = 1/16
The answer is A.
Step-by-step explanation:
The right answer is A - The theoretical probability of choosing a heart is StartFraction 1 over 16 EndFraction greater than the experimental probability of choosing a heart
