A town's recreation department is updating its parks. The parks must have slides and swings. Let x be the number of swing sets and y be the number of slides. The number of new slides must be more than three times the number of new swing sets. Each swing set costs $275 and each slide costs $168. They can spend no more than $1,250. Select all of the constraints for this situation. I know the two answers are : 275x+168y≤1250 y>3x x>0 y>0 but my question is how did you get the x>0 and y<0

In a study of the relationship between socio-economic class and unethical behavior, 129 university of california undergraduates at berkeley were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. they were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. after completing some unrelated tasks, participants reported the number of candies they had taken. it was found that those who were identiď¬ed as upper-class took more candy than others. in this study, identify: (a) the cases, (b) the variables and their types, (c) the main research question, (d) identify the population of interest and the sample in this study, and (e) comment on whether or not the results of the study can be generalized to the population, and if the ď¬ndings of the study can be used to establish causal relationships.
