21. There are 1276 students enrolled at a small university. The percentage of students according to classification is displayed in the pie chart. Which of the following is the number of students classified as sophomores? Round to the nearest whole number.
Answer: D
447 students are classified as sophomores.
To determine the number of sophomores, the percentage represented in the pie chart must be applied to the total enrollment of 1276 students. The calculation yields approximately 447 sophomores.
A) 370
This option is incorrect as it does not represent the calculated number of sophomores based on the percentage from the pie chart. The number 370 is lower than what would be derived from the given percentage.
B) 204
This option is also incorrect. The number 204 is significantly lower than the calculated value for sophomores and does not align with the percentage representation in the pie chart.
C) 255
This option is incorrect as well. A total of 255 sophomores does not match the expected number derived from the pie chart's percentage, which indicates a greater total.
D) 447
This option is correct, as it accurately reflects the calculation based on the percentage of students classified as sophomores in relation to the total student population of 1276.
Conclusion
The correct answer of 447 sophomores is directly supported by the percentage provided in the pie chart, accurately reflecting the total enrollment. Other options fail to match the expected calculation, indicating they do not represent the correct percentage of sophomores. Thus, the choice of 447 is both precise and substantiated by the data.
