C) changes with age.
D) does not change with age.
E) none of the above

Accepted Answer

The formula provided in the question seems to be a string of characters that do not correspond to any known equation for calculating life expectancy. Life expectancy is typically calculated using actuarial life tables, which are statistical models that incorporate mortality rates at various ages.
Life expectancy changes with age. As a person gets older, their life expectancy can increase or decrease depending on a variety of factors, including health, lifestyle, and advances in medical care. For example, once a person reaches the age of 70, their life expectancy is different from what it was when they were born because they have already surpassed many of the risks that could have caused an earlier death.
Therefore, the correct answer is:
c. changes with age.
