In Testing an Experimental Diet for Beef Cows,it Was Determined

Short Answer

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.
