pets survey

	pets	no pets
7th grade	17	25
8th grade	21	10

what percent of the 8th graders dont have a pet? round your answer to the nearest tenth of a percent.

Explanation:

Step1: Find total 8th graders

To find the total number of 8th graders, we add the number of 8th graders with pets and without pets. So, \(21 + 10 = 31\).

Step2: Calculate percentage

The number of 8th graders without pets is 10. To find the percentage, we use the formula \(\text{Percentage} = \frac{\text{Number of 8th graders without pets}}{\text{Total number of 8th graders}} \times 100\). Substituting the values, we get \(\frac{10}{31} \times 100\). Calculating this, \(\frac{1000}{31} \approx 32.258\). Rounding to the nearest tenth of a percent gives approximately 32.3%.

Answer:

32.3%
