Calculate the range of 20, -6, 25, 30, 21, 28, 32, 33, 34, 5, 3, 2, and 1.
Answer Details
To calculate the range of a set of numbers, you subtract the lowest number from the highest number.
In this case, the lowest number is -6 and the highest number is 34.
So the range is:
34 - (-6) = 40
Therefore, the correct answer is option D: 40.
