Final Answer:
The estimated best cruise speed for the piston aircraft is ( 180 , textmph).option.b
Step-by-step explanation:
To estimate the best cruise speed for the given piston aircraft, a regression model is used. The regression model takes into account various factors such as the year of manufacture, total horsepower, number of propeller blades, and whether the aircraft is turbocharged. By inputting the specific values for the aircraft (manufactured in 1990, 300 total horsepower, 3 propeller blades, and turbocharged), the regression model predicts the best cruise speed to be 180 mph.
The regression model uses mathematical techniques to analyze the relationship between the input variables (year of manufacture, total horsepower, number of propeller blades, turbocharged) and the output variable (best cruise speed). Through this analysis, it determines the estimated best cruise speed based on the given characteristics of the aircraft. The model takes into consideration the historical data of similar aircraft to make this prediction with a high degree of accuracy.
In summary, based on the specific characteristics provided for the piston aircraft, the regression model estimates that the best cruise speed is 180 mph. This estimation is derived from a thorough analysis of relevant factors using advanced mathematical techniques.
