In 1995 the life expectancy in a certain country was 71.4 years.In 2000,it was 74.8 years.Let E represent the life expectancy in the year t and let t represent the number of yers since 1995.The linear function E(t) that fits the data is E(t)=?t+?. Use the function to predict the life expectancy of males in 2004 E(9)=?
E(t)=0.68t+71.4
E(t)=0.68t+71.4 E(9)= 77.52
thank you.
No problem! ^_^
Got more?
That's all I've got right now. Thanks.
you welcome! :)
Oh Sally and Bills ages total 28.Bill is 20 years older than Sally, how old is Sally?
x = bills y = sally x+y = 28 y +20 = x
Solving them, u will get bill = 24 sally = 4
