In 1992, the life expectancy of males in a certain country was 61.6 years. In 1995, it was 65.2 years. Let E represent the life expectancy in year t and let t represent the number of years since 1990.
The linear function E(t) that fits the data is... E(t)=_____t + _______ (round to nearest 10th)
Use the function to predict the life expectancy of males in 2006.
E(14) = ___________ (round to nearest 10th)
I come up with:
E(t)=6t + 68.3--- for the 1st answer and
E(14) = 74.9
i.e. 74.88 rounded to nearest 10th
Is it right? if not please, please show and correct me!
