Correct Answer

A

Explanation

The range of a set of numbers is the difference between the largest and the smallest numbers in the set. The mode is the number that appears most frequently in the set.First, let's find the range. The largest number in the set is 10, and the smallest number is 4. Therefore, the range is \(10 - 4 = 6\).Next, let's find the mode. The number 10 appears most frequently in the set, a total of 5 times.Finally, we add the range and the mode together: \(6 + 10 = 16\).So, the sum of the range and the mode of the set of numbers is 16.
