The Social Security Administration determined that an average 30-year-old male in 2018 could expect to live at least 52.2 more years and that an average 30-year-old female in 2018 could expect to live at least 55.8 more years. (a) To what age could an average 30 -year-old male expect to live? Express your answer as an inequality. (b) To what age could an average 30 -year-old female expect to live? Express your answer as an inequality. (c) Who can expect to live longer, a male or a female? By how many years?

Key Concepts

Life Expectancy

Life expectancy is a statistical measure of the average time an individual is expected to live, based on demographic factors and current mortality rates. It is commonly used in fields such as public health, actuarial science, and social planning to make projections and inform policy decisions.

Inequality Representation

Inequality representation is a mathematical method used to express a range or limit of values. In the context of life expectancy, inequalities convey that an individual's life span is at least a certain number of years, indicating a minimum threshold rather than an exact value.

Age Calculation

Age calculation in this context involves adding the current age to the additional years expected to live. This straightforward arithmetic operation determines an approximate maximum or minimum lifespan based on given life expectancy figures.

Comparison of Quantities

Comparison of quantities is a fundamental mathematical concept used to evaluate the differences between values. In examining life expectancy by gender, it involves determining which group has a higher value and calculating the difference between the two to quantify the disparity.
