PART III QUESTIONS: Answer all questions in this part. Each correct answer will receive 4 credits. Clearly indicate the necessary steps and explain your reasoning. For all questions in this part, a correct numerical answer with no work shown will receive only I credit 21. The table below gives air pressures in kPa at selected altitudes above sea level measured in kilometers. Altitude (km] 0 5 Air Pressure (kPa)101 90 79 70 62 54 (a) Write an exponential regression equation that models these data rounding all values to the nearest thousandiki. Use this equation to algebraically determine the Air Pressure, to the nearest hundredth of a kPa, when the altitude is 10 km
