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 \(\frac{3}{50}\times100\%=6\%\).

Answer:

6%
