choose the correct answer below.
a. no, because the percents add up to more than 100%.
b. yes, because the percents do not add up to more than 360%.
c. yes, because the percents do not add up to more than 100%.
d. no, because the percents add up to more than 360%.

Explanation:

Step1: Calculate sum of percentages

$76 + 72+31 + 24+13=216$

Step2: Check condition for pie - chart

A pie - chart represents data as parts of a whole (100%). Since $216>100$, the data cannot be represented as a pie - chart.

Answer:

A. No, because the percents add up to more than 100%.
