The frequency table shows the ages of the actors
Oksanka [162]

The percentage of youth that are category 10 to 12 is the quotient of  their frequency to the total frequency

55% of the actors are 10 to 12 years old

<h3>How to determine the percentage?</h3>

From the complete question, we have the following parameters

  • Age 10 - 12 = 22 youths
  • Total youth = 40

The percentage of youth in the age category 10 - 12 is then calculated as:

Percentage = Frequency of age category 10 - 12/Total frequency

This gives

Percentage = 22/40

Evaluate the quotient

Percentage = 55%

Hence, 55% of the actors are 10 to 12 years old
