In Testing an Experimental Diet for Horses,it Was Determined That

Short Answer

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.
