Answer:

El estudiante obtuvo una calificación de 3.5 en su última evaluación.

Step-by-step explanation:

Dado que un estudiante obtuvo calificaciones de 5,7, 6,2 y 4,6 obteniendo un promedio total de 5 en sus calificaciones, para determinar qué nota obtuvo en la ultima prueba para lograr ese promedio, se debe realizar el siguiente cálculo:

(5.7 + 6.2 + 4.6 + X) / 4 = 5

(16.5 + X) / 4 = 5

16.5 + X = 4 x 5

16.5 + X = 20

X = 20 - 16.5

X = 3.5
