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 - fourth of the students?
select
(b) approximately what percentage of the students chose blue or pink?
10% 30% 50% 70%

Explanation:

Step1: Identify 1/4 of the circle

One-fourth of a circle corresponds to a 90-degree sector, which is a quarter of the full 360-degree circle. Looking at the pie chart, the Red sector is approximately a quarter of the circle.

Step2: Estimate Blue + Pink percentage

First, note that Blue is roughly half the circle (50%), and Pink is roughly one-fifth (20%)? No, re-estimate: Blue is ~40%, Pink is ~10%? No, combined, Blue and Pink make up about half the circle. Wait, recheck: the total circle is 100%. Blue is the largest slice (~40%), Pink is ~10%? No, no—wait, Red is 25% (1/4), Blue is ~40%, Pink ~15%, Purple ~10%, Green ~5%, Other ~5%. Adding Blue + Pink: 40% + 15% = 55%, which is closest to 50%.

Answer:

(a) Red
(b) 50%
