Pat is thinking of a number when she round her number to nearest 10 she get 580. when she round her number to the nearest 100 could she get 500

No, she could not because say her lowest possible number was 575. Remember the phrase: 5 or more raise the score, 4 or less, let it rest. We use 575 and we look to the 7, greater than 5 so we raise the score to 600. So, no this is not possible.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
