The circle graph describes the distribution of preferred transportation methods from a sample of 500 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?

Bus is the preferred transportation for 20 residents.
Bicycle is the preferred transportation for 100 residents.
Together, Streetcar and Cable Car are the preferred transportation for 210 residents.
Together, Walk and Streetcar are the preferred transportation for 55 residents.

Answer 1

Together, Streetcar and Cable Car are the preferred transportation for 210 residents.

This answer is found by combining the percent of people who prefer Streetcar and Cable Car and than multiplying that percent by 500.

15% + 27% = .15 + .27 = .42

.42 · 500 = 210 residents
