Thee dart board shown has 5 concentric circles whose centers are also the center of the square board. Each side of the board is 38 cm, and the radii of the circles are 2 cm, 5 cm, 8 cm, 11 cm, and 14 cm. A dart hitting within one of the circular regions scores the number of points indicated on the board, while a hit anywhere else scores 0 points. If a dart, thrown at random, hits the board, find the probability of scoring the indicated number of points. 7. 0 points 8. 1 point 9. 2 points 10. 3 points 11. 4 points 12. 5 points Find the probability that a point chosen at random from is on the given segment. 4. 5. 6. 7. 8. 9. 11. That of is approximated by a rectangle 100 mi by 50 mi. is approximately at the center of the state. If a meteor hit earth within 200 mi of , find the probability that the meteor landed in . 12. A stop light at an intersection stays red for 60 second, changes to green for 45 seconds, and then yellow for 15 seconds. If Joel arrives at the intersection at a random time, what is the probability that he will have to wait at a red light for more than 15 seconds? Find the area of the following: 1. 2. 3. All consecutive sides are 4. 7. 8. 9.
