Greg drew a pair of parallel lines and a line segment next to each other on a chalkboard. Which of these statements best compares the pair of parallel lines and the line segment? (1 point) Parallel lines and the line segment have no dimensions of measurement. The parallel lines and the line segment always meet at a common endpoint which is called the vertex. Parallel lines and a line segment cannot lie on the same plane at the same time because they do not overlap. The parallel lines extend infinitely in both directions, and the line segment has two endpoints.

The line plots show the number of hours two groups of teens spent online last week. How does the data compare for the two groups of teens? The 16- to 18-year olds spent about the same hours online, on average, as the 13- to 15-year olds. The mode for the hours spent online for the 13- to 15-year olds is greater than the mode for the hours last week for the 16- to 18-year olds. The median value for the hours spent online for the 13- to 15-year olds is greater than the median value for the hours spent online for the 16- to 18- year olds. The range of hours spent online for the 13- to 15-year olds is greater than the range of hours spent online for the 16- to 18-year olds.
