Your physics class decides to perform an experiment on circular waves. First, you make sure the water in the school swimming pool is level; that is, there are no waves. Next, a volunteer tosses a small marble near the center of the pool. Your teacher tells you the radius (in feet) of the outer ripple is given by r (t) = 0.73t, where t is the time in seconds after the marble hits the water given. The area of the circle is given by the function A(r) = π r2, where A(r) is the area in square feet and r is the radius in feet.

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
