Concept explainers
By the end of 2010, women made up more than half of the labor force in the United States, for the first time in the country’s history. The graphs show the percentage of jobs in the U.S. labor force held by men and by women from 1972 through 2009.
The formula
a Use the appropriate graph to estimate the percentage of jobs in the U.S. labor force held by women in 2000 Give your estimation to the nearest percent.
b Use the mathematical model to determine me percentage of jobs in the U.S. labor force held by women in 2000 Round to the nearest tenth of a percent.
c According to the formula when will 52% of jobs in the U.S. labor force be held by women Round to the nearest year.
