which situation describes a correlation that is not a causal relationship? (1) car color and number of car accidents(2) hours spent studying and test score(3) amount of exercise each week and the time it takes to run a mile(4) distance to reach a destination and the amount of gasoline used

I believe the answer would be (1) because they are not directly related

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
