+1443 500 people are asked to name their favorite color. The results of this survey are shown in the pie chart below:
Each sector of the pie chart makes an angle at the center. For example, the yellow sector makes an 18 degrees angle, since 18 degrees is 5 percent of 360 degrees.
Which sector makes an angle closest to 40 degrees? (Your answer should be a color word.)
+1443 If we consider ONLY the people who named a rainbow color (red, orange, yellow, green, blue, or purple), what percentage of those people preferred red?
use the data from problem part 1
+129852 Considering the "rainbow" colors, the percent who preferred red can be found thusly :
Red = .13 * 500 = 65
Orange = .04 * 500 = 20
Yellow = .05 * 500 = 25
Green = .15 * 500 = 75
Blue = .16 * 500 = 80
Purple = .12 * 500 = 60
So..... the % that preferred red is
65 / [ 65 + 20 + 25 + 75 + 80 + 60 ] =
65 / 325 =
1 / 5 =
20%
