Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. a pollster contacts 87 people in the 18-21 age bracket and finds that 74 of them respond and 13 refuse to respond. when 256 people in the 22-29 age bracket are contacted, 232 respond and 24 refuse to respond. assume that 1 of the 343 people is randomly selected. find the probability of getting someone in the 22-29 age bracket or someone who refused to respond.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
