PLEASE HELP ME

The circle graph describes the distribution of preferred transportation method from a sample of 400 randomly selected San Francisco residents.

circle graph titled San Francisco Residents' Transportation with five sections labeled walk 40 percent, bicycle 8 percent, streetcar 15 percent, bus 10 percent, and cable car 27 percent

Which of the following conclusions can be drawn from the circle graph?

Together, Walk and Cable Car are the preferred transportation for 268 residents.
Together, Walk and Streetcar are the preferred transportation for 55 residents.
Bicycle is the preferred transportation for 40 residents.
Bus is the preferred transportation for 50 residents.

Answer 1

Bus is the preferred transportation for 10% of the sample, which would be 0.10 x 400 = 40 residents. Therefore, the conclusion that "Bus is the preferred transportation for 50 residents" cannot be drawn from the given information.

The other conclusions can be drawn from the circle graph:

- Together, Walk and Cable Car are the preferred transportation for 68% + 27% = 95% of the sample, which would be 0.95 x 400 = 380 residents. Therefore, the conclusion that "Together, Walk and Cable Car are the preferred transportation for 268 residents" is possible.
- Together, Walk and Streetcar are the preferred transportation for 40% + 15% = 55% of the sample, which would be 0.55 x 400 = 220 residents. Therefore, the conclusion that "Together, Walk and Streetcar are the preferred transportation for 55 residents" is possible.
