Final answer:
To find the number of high school students expected to have cheated in the last year, multiply the percentage of students who have cheated by the total number of high school students.
Step-by-step explanation:
To find the number of high school students expected to have cheated in the last year, you need to multiply the percentage of students who have cheated (30%) by the total number of high school students (120).
Let's calculate:
- Percentage of students who have cheated = 30%
- Total number of high school students = 120
- Number of students expected to have cheated = Percentage of students who have cheated * Total number of high school students
Plugging in the values:
- Number of students expected to have cheated = 30% * 120
- Number of students expected to have cheated = 0.3 * 120
- Number of students expected to have cheated = 36
Therefore, 36 high school students are expected to have cheated in the last year.
