During a pumpkin launching contest, two pumpkins are launched at the same time. the path of pumpkin a is modeled by the equation h(x) = –0.01x2 + 0.32x + 4. the path of pumpkin b is modeled by the equation h(x) = –0.01x2 + 0.18x + 5. if x represents the distance the pumpkin traveled and h(x) represents height, what does the intersection point of the equations represent?

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
