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%

Respuesta :

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:

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

                A.  9%                        

Step-by-step 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:

          [tex]\dfrac{Frequency\ of\ red}{Total}\times 100\\\\i.e.\\\\=\dfrac{14}{162}\times 100\\\\\\\\=8.642\%[/tex]

which on rounding to the nearest percent is:

           9%

Hence, the correct answer is: Option: A
