Per capita consumption of fresh vegetables in a certain country Year 1980 Vegetable consumption, V (pounds per person) 148.1 1985 157 1990 165.1 1995 2000 176.1 202.7 (a) Find the function of the quadratic model that gives the per capita consumption of fresh vegetables in pounds per person, where t is the number of years since 1980, with data from 0sts 20. Examine the equation graphed on a scatter plot of the data. (Round all numerical values to three decimal places.) v(t)=V(t)=-0.52412 + 20.4041 + 148.1 (b) Do you believe that the equation in part (a) is a good fit? The model does not appear to be a good fit. The model appears to be a good fit. This cannot be determined. (c) The per capita consumption in 2001 had not yet been tabulated when the data in the table were published. What does the quadratic model give as the per capita consumption in 2001? (Round your answer to one decimal place.) 346.2 x pounds per person (d) According to your model, in what year will consumption exceed 225 pounds per person. 36.9
