Correct Answer

Explanation

Range = 0.47 - (-0.53)= 1.0To find the range of a set of numbers, we subtract the smallest number from the largest number in the set.In this case, the largest number is 0.47 and the smallest number is -0.53.So, the range is:0.47 - (-0.53) = 0.47 + 0.53 = 1.0Therefore, the range of the given set of numbers is 1.0.
