x 21 mx + ny =P x23 c - dy = 0 725 Women in the Labor Force The number of women in the labor force is expected increase during the 1990s, but not as dramatically as occurred during the 1979s, O forecasting consultant uses the linear equation n - 29.6 + 1.20t to predict the numbs of women between the ages of 35 and 44 who will be in the labor force, In this equation, equals the number of women (aged 35 to 44) in the labor force (measured in millions) an t equals time measured in years since 1981 (t = 0 corresponds to 1981), If n is plottedo the vertical axis: (a) Graph the equation, (b) Identify the slope and y intercept (n intercept, here). (c) Interpret the meaning of the slope and n intercept in this application, (d) Predict the number of women in this age group who will be in the labor force in 1925 In the year 2000. 26 The chamber of commerce for a summer resort is trying to determine how many tourist will be visiting each season over the coming years, A marketing research firm has estimated that the number of tourists can be predicted by the equation p - 275,090+ 7,500t, where p = number of tourists per year and t = years (measured from this current season). Thus t = 0 identifies the current season, t = 1 is the next season, etc, If p is plotted on the vertical axis: (a) Graph the equation. (b) Identify the slope and y intercept (p intercept, here), (c) Interpret the meaning of the slope and p intercept in this application. 27 Think Metric! C= ;F - 180 is an equation relating temperature in Celsius units to temperature measured on the Fahrenheit scale. Let C - degrees Celsius and F- degrees Fahrenheit; assume the equation is graphed with C measured on the vertical axis. (a) Identify the slope and C intercept. (b) Interpret the meaning of the slope and C intercept for purposes of converting from Fahrenheit to Celsius temperatures. (c) Solve the equation for F and rework parts a and b if F is plotted on the vertical axis, /28 A police department believes that the number of serious crimes which occur each month can be estimated by the equation c = 1,200 - 12.5p where c equals the number of serious crimes expected per month and p equals the number of officers assigned to preventive patrol. If c is graphed on the vertical axis: (a) Identify the slope and interpret its meaning. (b) Identify the c intercept and interpret its meaning. (c) Identify the p intercept and interpret its meaning. 29 The book value of a machine is expressed by the equation where V equals the book V = 60,000 - 7,500t
