72 A. Yes, it is appropriate because as the number of items produced increases, so does the cost.B. Yes, it is appropriate because the coefficient of determination is close to 1, and this is an interpolatin valueC. No, it is not appropriate because the data should be modeled with a logistic functionD. No, it is not appropriate because the data should be modeled with an exponential function A company examined cost data in an effort to model the relationship between number of items produced, x, and cost, C. The regression equationis C(x) = 0.52x + 366 with a coefficient of determination of 2 = 0.92.
