Use the function to predict the mortality rate of children under five in a country where $50 \%$ of adult females are literate.
$\square$ per thousand
(Type an integer or a decimal.)
Solution
Solution Steps
Step 1: Find the equation of the line
The equation is already given in slope-intercept form: f(x) = -1.9x + 241, where x represents the percentage of literate adult females and f(x) represents the mortality rate per thousand.
Step 2: Substitute the given percentage into the equation
We are given x = 50, representing 50% of adult females being literate. Substitute this value into the equation:
f(50) = -1.9 * 50 + 241
