Question

a random sample of students was surveyed and asked to list their grade level and whether or not they have a pet. results are shown in the table below. what percent of the 7th graders dont have pet? round your answer to the nearest whole number percent.

Explanation:

Step1: Identify the number of 7th graders without pets and total 7th graders

Number of 7th graders without pets: \(26\)
Total number of 7th graders: \(42\)

Step2: Use the percentage formula

The percentage formula is \(\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100\%\)
Substitute the values: \(\text{Percentage}=\frac{26}{42}\times 100\%\)
Calculate \(\frac{26}{42}\approx0.619\)
Then \(0.619\times100\% = 61.9\%\)

Answer:

\(62\%\)
