A survey find that 40% of the students ride in a car to school area would like to estimate the probability that if three students were randomly selected only one ride in a car to simulate this probability she lets the number is 012 and three Rivers in a student who ride in a car to school then 45678 and nine represent a student who does not ride in a car to school she has a computer randomly selects three numbers she repeat this process for 20 trials the result of the trails are shown on the table

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
