Question

You collected the following data about the colors of dresses at the prom:

Red
Black
Blue
White
Other
14
37
22
56
33

When making a pie chart for this data, what percentage of the dresses would the sector labeled "Red" include? (round to the nearest percent)
A. 9%
B. 14%
C. 23%
D. 25%

Answer 1

sum=14 + 37 + 22 + 56 + 33 = 152 => 100%
red = 14 => x%

100% / 152 = x / 14
x = 100 × 14 / 152
x = 1400 / 152
x = 9,21% = 9%

Answer 2

The percentage of the dresses would the sector labeled "Red" include is:

A. 9%

Explanation:

Color Frequency

Red 14

Black 37

Blue 22

White 56

Other 33

Total 162

The percentage of the dresses that would include the sector labeled Red is:

`(Frequency\ of\ red)/(Total)* 100\\\\i.e.\\\\=(14)/(162)* 100\\\\\\\\=8.642\%`

which on rounding to the nearest percent is:

9%

Hence, the correct answer is: Option: A
