What percent of the students in the School of Rock play bass? Round your answer to the nearest whole number percent.



Answer :

To determine what percentage of the students in the School of Rock play bass, follow these steps:

1. Identify the Total Number of Students:
The total number of students in the School of Rock is given in the table:

[tex]\[ \text{Total students} = 185 \][/tex]

2. Identify the Number of Students Playing Bass:
The number of students who play bass is also given in the table:

[tex]\[ \text{Number of bass players} = 42 \][/tex]

3. Calculate the Percentage of Students Playing Bass:
To find the percentage, we use the formula:

[tex]\[ \text{Percentage} = \left( \frac{\text{Number of bass players}}{\text{Total students}} \right) \times 100 \][/tex]

Substituting the values we have:

[tex]\[ \text{Percentage} = \left( \frac{42}{185} \right) \times 100 \][/tex]

Performing the division first:

[tex]\[ \frac{42}{185} \approx 0.22702702702702705 \][/tex]

Then multiplying by 100:

[tex]\[ 0.22702702702702705 \times 100 \approx 22.702702702702705 \][/tex]

4. Round to the Nearest Whole Number:
The result 22.702702702702705 is then rounded to the nearest whole number:

[tex]\[ \text{Rounded Percentage} = 23\% \][/tex]

Hence, approximately [tex]\(23\%\)[/tex] of the students in the School of Rock play bass.
