Answer
Answer:
6%
Explanation:
Step1: Calcular el total de encuestados
El número total de estudiantes satisfechos es (17 + 25=42), y representan el 84% del total de encuestados. Sea (T) el total de encuestados. Entonces (\frac{42}{T}=0.84), de donde (T=\frac{42}{0.84} = 50).
Step2: Calcular el total de estudiantes no satisfechos
El número total de estudiantes no satisfechos es (3 + 5 = 8).
Step3: Calcular el porcentaje de estudiantes no satisfechos en pintura al óleo
El número de estudiantes no satisfechos en pintura al óleo es 3. El porcentaje (x) se calcula como (\frac{3}{50}\times100%=6%).
