Explanation:
➡ To find the lower and upper bounds of the expression (0.1 - 0.2)^2 rounded to 1 decimal place, we need to consider the possible values within the range of the expression when rounded.
Step 1: Evaluate the expression (0.1 - 0.2)^2:
(0.1 - 0.2)^2 = (-0.1)^2 = 0.01
Step 2: Determine the lower and upper bounds after rounding to 1 decimal place:
Since the result is 0.01, it will be rounded to 0.0 to one decimal place. The range of possible values when rounded to 1 decimal place would be [0.0, 0.1).
Therefore, the lower bound is 0.0, and the upper bound is 0.1.
