Mathematics
1 answer:
MrMuchimi3 years ago
7 0

Answer:

3.1 (nearest tenth)

Step-by-step explanation:

Year (independent variable) = x

Percent of adults (dependent variable) = y

Rate of change is given as = \frac{y_2 - y_1}{x_2 - x_1}.

Let,

(1989, 20) = (x_1, y_1)

(2007, 76) = (x_2, y_2)

Plug in the values into the equation

Rate of change = \frac{76 - 20}{2007 - 1989}

Rate of change = \frac{56}{18} = 3.1 (nearest tenth)
