SOLUTION: The mortality rate from heart disease can be modelled by the relation M = 88. 8(0. 9418) , t where M is the number of deaths per 100 000 people and t is the number of years since

Question 1195761: The mortality rate from heart disease can be modelled by the relation M = 88. 8(0. 9418) ,
t
where M is the number of deaths per 100 000 people and t is the number of years since 2000.
a) What was the initial mortality rate in the year 2000? ✓
b) According to this equation, is the mortality rate increasing or decreasing over time?
Explain how you know. ✓✓

a.The mortality at t=0 is 88.8 per 100,000.
b. since the coefficient of t is < 1, the mortality is decreasing over time by 5.82% per year.
A number on the interval (0, 1) that is raised to a positive power will have a value less than the number itself.
