Final answer:
To find the total number of students surveyed when an equal number of students from each of the four academic years were surveyed, you would multiply the number surveyed from one year group by four. Without a specific number given for any year, we cannot determine the total.
Step-by-step explanation:
The question you've asked pertains to how the total number of students surveyed can be determined when an equal number of first, second, third, and fourth year students were surveyed. To find the total number of students surveyed, you would need to know the specific number of students surveyed in one of the year groups since the number is the same across all four groups. You would then multiply this number by four to account for each year group.
In the context of the information provided, it is not explicitly stated how many students from each year were surveyed. However, if we use the example data provided, we can illustrate how you would find the total if we knew the numbers for each year. For instance, if 5 first-year students, 5 second-year students, 5 third-year students, and 5 fourth-year students were surveyed, then the total number of students surveyed would be 5+5+5+5, which equals 20 students.
