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

What is the total length of nine pieces of chain each measuring 13 yards, 1 foot, 5 inches? Convert the answer to larger units w
dimulka [17.4K]

Answer: The total length of nine pieces of chain is 121.248 yards.

Explanation:

Since we have given that

Length of each chain = 13 yards, 1 foot, 5 inches

As we know that

1\ inch=\frac{1}{12}\ foot\\\\5\ inches=\frac{5}{12}=0.4167\ foot\\\\\text{Total foot = 1+0.4167 =1.4167 foot}\\\\And\\\\1\ yard=3\ foot\\\\1\ foot=\frac{1}{3}\ yard\\\\1.4167\ foot=\frac{1.4167}{3}=0.472\ yards\\\\So,\\\\13\ yards+0.472=13.472\ yards

On Converting it into larger units, we get 13.472 yards

Now, Number of pieces of chain =9

Length of 9 pieces is given by

13.472\times 9=121.248\ yards

Hence, Nine pieces  of chain are 121.248 yards long .
