Question
testing the table shows the number of students who took the act between 2011 and 2015. part a find the average rate of change in the number of students taking the act from 2011 to 2015. average rate of change = part b
Step1: Identificar los valores iniciales y finales
En 2011 (\(x_1 = 2011\)), el número de estudiantes es \(y_1=1623112\). En 2015 (\(x_2 = 2015\)), el número de estudiantes es \(y_2 = 1924436\).
Step2: Aplicar la fórmula del promedio de cambio
La fórmula del promedio de cambio es \(\frac{y_2 - y_1}{x_2 - x_1}\). Sustituimos los valores: \(\frac{1924436-1623112}{2015 - 2011}\).
Step3: Realizar las operaciones
Primero, calculamos el numerador: \(1924436-1623112 = 301324\). Luego, el denominador: \(2015 - 2011=4\). Finalmente, \(\frac{301324}{4}=75331\).
