Provide an appropriate response.In testing an experimental diet for goats, it was determined that the (average) live weight w (in kilograms) of a goat was statistically a linear function of the number of days d after the diet was started where 0 ? d ? 100. The weight of a goat starting the diet was 12 kg and 25 days later it was 20 kg. Determine w as a linear function of d and find the average weight of a goat when d = 80.
