The correct answer is A i believe :)
You add the equations together making sure one of the variables disappears by making one negative and one positive. In this situation y would alrady disappear 8x+y=-16

Step-by-step explanation:
you multiply 3x4=12
Probability is represented as the number of ways for an event to happen over all possible outcomes. For the theoretical probability, there is 1 black spot and 5 total options. Therefore, the probability is 1/5, or 0.20.
For experimental probability, there were 103 times it landed on black out of 500 spins. The probability is 103/500, or 0.206.
Lastly, the multiple choice. The larger sample size you take, assuming a fair spinner, the more likely you are to see results similar to the theoretical probability. This is because the larger sample size taken, the less each individual spin effects the outcome.
