Look at this set of 6 numbers:

5 4 7 3 9 2
By how much would the range increase if the number 5 were added to the set?

1 answer

To find out how the range would change by adding the number 5 to the set, we first need to determine the range of the original set of numbers.

The original set is: 5, 4, 7, 3, 9, 2

  1. First, find the minimum and maximum values in the original set:

    • Minimum = 2
    • Maximum = 9
  2. Calculate the range of the original set: \[ \text{Range} = \text{Maximum} - \text{Minimum} = 9 - 2 = 7 \]

Next, we add the number 5 to the set. The new set becomes: 5, 4, 7, 3, 9, 2, 5

  1. Now find the new minimum and maximum values:

    • Minimum = 2 (remains the same)
    • Maximum = 9 (remains the same)
  2. Calculate the new range: \[ \text{New Range} = \text{Maximum} - \text{Minimum} = 9 - 2 = 7 \]

Finally, we determine how much the range has changed: \[ \text{Change in Range} = \text{New Range} - \text{Original Range} = 7 - 7 = 0 \]

Therefore, the range does not increase when the number 5 is added to the set. The answer is: \[ \text{The range increases by } 0. \]
