Provide an appropriate response.In testing an experimental diet for beef cows, it was determined that the (average) live weight w (in kilograms) of a cow was statistically a linear function of the number of days d after the diet was started, where 0 ? d ? 300. The weight of a cow starting the diet was 125 kg and 100 days later it was 245 kg. Determine w as a linear function of d and find the average weight of a cow when d = 200.
