45. If the best-fitting line (figured using computer software) is approximately f(x) = -1.182x + 17.012, then what does the model predict the number of errors made per week when the employee has worked on the assembly line for 13 months? (Round to the hundredths.) A) 1.24 B) 3.05 C) 1.65 D) 0.92 C) 13.6 46. According to the model f(x) = -1.182x + 17.012, how many months would a worker work on the line before the number of assembly errors are 0? (Substitute 0 for f(x) and solve for x.) Round the answer to tenths. A) 16.5 B) 14.4 E) 2.24 D) 12.9 E) 12.4
