Math Problem Statement
Solution
To find the error interval for the number , which is rounded to two decimal places as , we need to determine the range of values that could have been before rounding.
Step-by-step solution:
-
Lower Bound: The smallest number that rounds up to 4.63 when rounded to 2 decimal places is halfway between 4.62 and 4.63. This is:
-
Upper Bound: The largest number that rounds down to 4.63 when rounded to 2 decimal places is halfway between 4.63 and 4.64. This is: However, since the upper bound is not included in the interval, we exclude it by writing .
Final Error Interval:
The error interval for is:

Here are five related questions to expand your understanding:
- How would the error interval change if the number was rounded to 1 decimal place?
- What is the concept of rounding in terms of significant figures?
- Can you describe how rounding to different decimal places affects precision?
- How do we calculate error intervals for numbers in scientific notation?
- How is the concept of error intervals applied in real-world measurement scenarios?
Tip: When working with rounding and error intervals, always remember that the interval excludes the upper bound. This ensures the correct representation of the range of possible values.
