Biologists use the overhead width measured (in centimeters) of a Weddell Seal to estimate it's weight (in kilograms). y = - 157 + 40.2x R2 = 0.83 a. According to the equation, what is the predicted weight of a Weddell Seal that has an overhead with of 23 centimeters? b. What does the slope mean in terms of the situation? c. What does the y-intercept mean in terms of the situation? d. What does the coefficient of determine mean in terms of the situation?
