Mass of Gray Wolves The relationship between body mass and age in male gray wolves from the Superior National Forest of northeastern Minnesota can be estimated by M(x) = 27.14 + 3.8x – 0.32r, 1sxs 9, where M(x) is measured in kilograms and x is the estimated age of wolves in years. Source: Journal of Mammalogy. (a) What does this formula predict for the body mass of a 2-year-old male wolf? 7-year-old male wolf? (b) What does this formula predict for the maximum body mass, and when does that occur?
