Marcus states that angle ORP and angle LRP are a linear pair. Which best describes his statement? He is correct. The angles share a common vertex so they are a linear pair.

He is correct. The angles share a common ray so they are a linear pair.

He is incorrect. Angle ORP does not form a linear pair with another angle in the diagram.

He is incorrect. Ray RO and ray RL are not opposite rays.

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?
