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

Short Answer

In testing an experimental diet for sheep,it was determined that the (average)live weight w (in kilograms)of a sheep was statistically a linear function of the number of days d after the diet was started,where 0 ≤ d ≤ 150.The weight of a sheep starting the diet was 15 kg and 40 days later it was 43 kg.Determine w as a linear function of d and find the average weight of a sheep when d =100.
