Answer:
It ranges from 350,000 to 449,000.
Step-by-step explanation:
Here, the given figure is
400,000.
The number is rounded to 400,000 when it falls between 350,000 and 449,000, including both endpoints.
Specifically, numbers that have 3 in the hundred-thousand place are rounded to 400,000 when the ten-thousand digit is 5 or greater.
Conversely, if a number has 4 in the hundred-thousand place, it rounds to 400,000 with a ten-thousand digit less than 5.
Therefore, the possible exact count of museum visitors would range:
From 350,000 to 449,000.
