We are asked to determine if the number sets 1857300 and 1857800 are the same number sets. To answer this, we need to recall and define that number sets are a collection of distinct objects such as elements and numbers. The answer to this question is that these two sets are NOT the same, the first one contains "3" while the second one contains "8".

I have added a screenshot with the complete question.

Answer:
At least 7 more students need to sign up for the field trip to be scheduled

Explanation:
Assume that the least number of students remaining to register for the trip to be scheduled is x.

total number of students = students who already registered + x

We are given that, the least number of students required for this trip is 30. This means that:
total number of students ≥ 30
Now, we know that 23 students already registered.

The inequality now is:
x + 23 ≥ 30
x ≥ 30 - 23
x ≥ 7

This means that at least 7 more students must register for the trip to be scheduled.

Hope this helps :)
