Provide an appropriate response.In testing an experimental diet for horses, it was determined that the (average) live weight w (in kilograms) of a horse was statistically a linear function of the number of days d after the diet was started where 0 ? d ? 300. The weight of a horse starting the diet was 170 kg and 120 days later it was 362 kg. Determine w as a linear function of d and find the average weight of a horse when d = 250.
