Answer:

Error interval is
$35\leq x< 45$

Explanation:

Given: A number x becomes 40 if it is rounded to 1 significant figure

To find: error interval for x

Solution:

In the given question, an error interval is the range of values that a number x can be equal to before it is rounded to 1 significant figure.

As a number x becomes 40 if it is rounded to 1 significant figure, error interval is
$35\leq x< 45$ .

A number x in this interval becomes equal to 40 if it is rounded to 1 significant figure.
