Answer:
Life expectancy of woman in [tex]2005=81[/tex] years
Step-by-step explanation:
Life expectancy in [tex]1995=80.2[/tex] years
In every [tex]5[/tex] years increase in life expectancy [tex]=0.4[/tex]
So per year increase = [tex]\frac{Increase\ in\ 5\ years}{5}[/tex]
[tex]=\frac{0.4}{5}[/tex]
Total years between [tex]1995[/tex] and [tex]2005=2005-1995=10[/tex]
Increase in [tex]10[/tex] years = increase in [tex]1[/tex] years [tex]\times10[/tex]
[tex]=\frac{0.4}{5}\times10\\=0.4\times2\\=0.8\ years[/tex]
So life expectancy of woman in [tex]2005[/tex]
[tex]=80.2+0.8\\=81\ years[/tex]
