Answer: 81 students.
Step-by-step explanation: We can calculate the number of freshman students who selected the Dolphins by following these steps: 1. Determine the total number of students surveyed who selected the Dolphins (180). 2. Find out the percentage of freshman students (45%) who selected the Dolphins by dividing the number of freshman students by the total number of students who selected the Dolphins and multiplying by 100. We can calculate the number of freshman students who were surveyed like this: 1. Start by finding the total number of freshman students in the survey. In order to do this, multiply the total number of students surveyed (180) by the percentage of freshman students (45%). 180*45% = 81. So, there were 81 freshman students surveyed. I think this is correct. But I hope this helps and let me know if you have any questions.
