To determine the number of Black, non-Hispanic students in a U.S. public school with 1,000 students based on the circle graph, you'll need to know the percentage breakdown for that demographic. If the graph indicates that, for example, Black, non-Hispanic students represent 17% of the student population, you would calculate the expected number of students as follows:
\( \text{Number of Black, non-Hispanic students} = \text{Total number of students} \times \text{Percentage of Black, non-Hispanic students} \)
Using the hypothetical 17%:
\( 1,000 \times 0.17 = 170 \)
Thus, if the percentage breakdown for Black, non-Hispanic students is indeed 17%, then you would expect 170 students to be Black, non-Hispanic in that school.
If this percentage is what is represented in the graph, then that would be your answer. Therefore, the correct response is 170.
