The graph shows the solution to a system of inequalities: Solid line joining ordered pairs 0, 3 and 7, 0. Shade the portion of the graph below the line in the first and fourth quadrants.

Which of the following inequalities is modeled by the graph?

2x + 5y ≥ 14; x ≥ 0
2x + 5y ≤ 14; x ≥ 0
2x − 5y ≤ 14; x ≥ 0
−2x − 5y ≤ 14; x ≥ 0

In a bumper test, three types of autos were deliberately crashed into a barrier at 5 mph, and the resulting damage (in dollars) was estimated. five test vehicles of each type were crashed, with the results shown below. research question: are the mean crash damages the same for these three vehicles? goliath varmint weasel 1600 1290 1090 760 1400 2100 880 1390 1830 1950 1850 1250 1220 950 1920
