Question

in 1994 the life expectancy of malews in a certain country was 70.9 years. In 1998 it was 73.6 years. Let E represent the life expectancy in year t and let t represent the number of years since 1994
The linear functionE(t) that fits the data is
E(t)= 80.6t+81.0
Use the function to predict the life expectancy of males in 2004
E(10)=85.9

Is this correct?

Answer 1

If (t)= 80.6t + 81.0 , how does E(10) = 85.9? I believe there is a typo in the slope of the linear function E(t).

Answer 2

E(t)=80.6t+81.0 and E(10)= 85.9 is what I came with which I guess you are saying that it is wrong thanks I will try to rework the problem
