Question 338509: DATA
Year Males % Females %
1981, 43.4, 41.7
1983, 39.6, 40.5
1985 26.7, 27.7
1986, 25.2, 27.0
1989, 22.6, 23.5
1991, 22.6, 25.6
1994, 27.3, 28.9
1995, 28.5, 29.5
1996, 29.1, 31.0
I graphed it and the vertex for Males is (90, 20.2) and females is (88.5, 23.5) but you can check
a) Algebraic expression to model each case
b) Use equations of each curve to find what year males and females have the same percentages.
THANKYOU
