Hello! I am confused as to how this problem works. Can youplease help? In 1994 the life expectancy of males in a certain country was68.7 years. In 1998, it was 72.6 years. Let E represent the lifeexpentancy in year t and let t represent the number of years since1994. The linear function E(t) = __t + ___ (round to the nearesttenth). Use the function to predict the life expectancy of males in2004. E(10)= I think the E(t) for 1998 is 1998(4) + __ but I don't knowwhat the number to be added is. Am I even on the right track?Please help! Hello! I am confused as to how this problem works. Can youplease help? In 1994 the life expectancy of males in a certain country was68.7 years.

Explanation / Answer

Thanks for your help! However, I am still confused. For thefinal answer you gave the equation t + 68.4 and thensaid that E(10) = 78.7. If you are just adding 10 to the 68.4wouldn't the answer be 78.4?? Am I missing something? Thanks!
