. Run the reduced model (that now includes only three independant variavles), and show the prediction equation. e. Interpret the coefficient of the predictor "Smoker" in this model. What does its value mean in this model? f. A smoker, whose both parents passed at the age of 85, is 62 years old. How many more years is he expected to live? g. His friend is not a smoker who lost his mother when she was 70 years old, and father when he was 60 years old. How long is he expected to live? h. Can you determine with 90% confidence which of the two friends will die at a younger age?

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

What is the result of converting 60 ounces to pounds remember there are 16 ounces in a pound

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
