let 1991 be t=0
then 1991 life exp ---> (0,73.7)
and 1995 life exp ----> (4,77.4)
slope = (77.4 - 73.7)/4 = .925
E(t) = .925t + 73.7
2008 ----> t = 17
E(17) = .925(17) + 73.7 = 89.425
What is the name of that country? Utopia?
In 1991 the life expectancy of males in a certain country was 73.7 years old, In 19951995 it was 77.4 years. Let E represent the life expectancy in year (t) and let (t) represent the number of years
since 1991 What is the linear function fits the data. Use the function to predict the life expectancy of males in 2008
