Question

each student in a school was asked, \what is your favorite color?\ the circle graph below shows how they answered.
(a) which color was chosen by approximately one - third of the students?
(b) approximately what percentage of the students chose purple or green?
20% 40% 60% 80%

Explanation:

Step1: Analizar la porción del círculo

Un tercio de un círculo es aproximadamente \( \frac{1}{3}\times100\%\approx33.3\%\). Observando el gráfico circular, el color azul ocupa una porción similar a un tercio.

Step2: Calcular la suma de Purple y Green

Contar el porcentaje aproximado de Purple y Green. Purple parece ocupar un poco más de un cuarto (\(25\%\)) y Green un poco menos de un cuarto. Junto, suman aproximadamente \(40\%\).

Answer:

(a) Blue
(b) 40%
