Question

preston asked freshman, sophomores, and juniors at his school whether they generally completed their homework at school, at home, or elsewhere. what percentage of the juniors that preston surveyed generally completed their homework at home? round your answer to the nearest percent. %

Explanation:

Step1: Identify relevant numbers

From the table, number of juniors who completed homework at home is 55, total number of juniors surveyed is 138.

Step2: Calculate the percentage

Percentage = (Number of juniors who completed at home / Total number of juniors) 100 = ($\frac{55}{138}$) 100
First, calculate $\frac{55}{138} \approx 0.39855$
Then multiply by 100: $0.39855 * 100 \approx 39.855$

Step3: Round to nearest percent

Rounding 39.855 to nearest percent gives 40.

Answer:

40
