Alex knows 18% of the students surveyed at his school are dropped off by car while 22% walk or ride bikes and the rest ride the bus Which table could represent this information ?

Answers

Answer:

The second option.

Step-by-step explanation:

First, the percentages in the "walk" and "ride bike" sections will have to add to 22% as the information says. All of them do except the third option, so that's ruled out.

Next, the rest of the categories have to finish to complete 100%- so they need to add to 78%. Only one of them do, the second with 18% car and 60% bus!

•The finishing point will be located in quadrant S
Explanation: the x and y values determine where the points are located on the graph

2. The starting point is (-5.4, 3) and the checkpoint is (5.4, 3). The difference is they’re both in different quadrants, and one has a negative value, and the other is positive. They are related because they’re all in one race, and the checkpoint will be involved in the race, most likely between the start and finish points, located in quadrant P.
