Final Answer:
Out of the 1,750 students, approximately 350 of them got part-time jobs through the school's career office.
Step-by-step explanation:
The survey indicates that 20% of the students (40 out of 200) got part-time jobs through the school's career office. To estimate the total number of students who secured jobs through the career office for the entire student population (1,750), we can apply this percentage. Therefore, approximately 350 students (20% of 1,750) obtained jobs through the school's career office. This calculation assumes a proportional distribution of job placements based on the survey results across the entire student body.
