A number, x, rounded to 2 decimal places is 15.38, write the error interval

error interval is 15.375 ≤ x < 15.385

Step-by-step explanation:

An error interval shows the range of value a number could have taken before rounded or truncated. It is expressed using inequality as range showing the upper bound and the lower bound. It shows a range of values in which a number could be before it was rounded. The upper bound shows the highest value the number can be while The lower bound shows the lowest value the number can be.

x = 15.38 to 2 decimal places.

The lower bound = 15.375

The upper bound = 15.385

Therefore the error interval = 15.375 ≤ x < 15.385
