Indicate clearly the methods you use, because you will be graded on the correctness of your methods, as well as on the accuracy of your results and explanation. for part a, briefly describe the scatterplot you construct on your calculator (include labels). animal-waste lagoons and spray fields near aquatic environments may significantly degrade water quality and endanger health. the national atmosphere deposition program has monitored the atmosphere ammonia at swine farms since 1978. the data on the swine population size (in thousands) and atmospheric ammonia (in parts per million) for one decade are given below. year 1988 1989 1990 1991 1992 1993 1994 1995 1996 199 swine population 0.38 0.50 0.60 0.75 0.95 1.20 1.40 1.65 1.80 1.85 atmospheric ammonia 0.13 0.21 0.29 0.22 0.19 0.26 0.36 0.37 0.33 0.38 a) construct a scatterplot for this data. (find out from your instructor on how to submit your scatterplot). b) the value for the correlation coefficient for this data is 0.85. interpret this value. c) based on the scatterplot in part (a) and the value of the correlation coefficient in part (b), does it appear that the amount of atmospheric ammonia is linearly related to the swine population size? explain. d) what percent of the variability in atmospheric ammonia can be explained by swine population size?

Brittany has designed four different birdcages, each with the same volume: a square pyramid, a cylinder, a cone, and a sphere. the zoo wants to use one of brittany’s designs but plans to change the volume of the cage. find the design change that would result in the birdcage with the greatest volume. increase the area of the base of the square pyramid by a factor of ten. increase the height of the cylinder by a factor of ten. increase the radius of the cone by a factor of ten. increase the radius of a sphere by a factor of ten. juan wants to build a greenhouse in his back yard. he needs to maximize the ratio of floor area to structure volume in order to provide the most room for plants while minimizing the area to be heated. find the description of the structure that best meets juan’s criteria. a cube with a side length of 12 feet a cone with a diameter of 12 feet and a height of 10 feet a square pyramid with a base side length of 12 feet and a height of 9 feet a hemisphere with a diameter of 12 feet marion has a bicycle that she is planning to take for a ride. the rim of the rear wheel lies 41 cm from the center of the wheel. the tire itself has a thickness of 3 cm.in order to marion to ride her bicycle 96,712 cm, approximately how many rotations will the rear wheel make? 350 15.9 376 5133 an isosceles trapezoid has perimeter of 42 inches. each of the congruent nonparallel sides is 5 inches long, and the trapezoid is 3 inches tall. how long are the two parallel sides? 10 inches and 16 inches 12 inches and 20 inches 16 inches and 16 inches 10 inches and 22 inches
