The answer is 21 or letter a.
The range is one of the measures of dispersion in Statistics. Sometimes researchers do not only rely on the mean or average of a given data, but they also consider the distance of the values from each other.Some Measures of Dispersion or Spreadness
3. Standard Deviation
4. Mean Deviation
Range is the simplest and the most weak measure of dispersion since it only considers the highest and lowest value in the data. It neglects the significance of each value in the data.
Range is the distance from the highest value to the lowest value or . We already have the range value, which is 14 and the lowest value is 7. Substitute and into the formula, apply the inverse operation, and simplify.
From the solution process above, this means that the highest value is 21.

first, when you write the expressions down to divide them, make sure
to include _every_ power of x. if there is a power missing in the
given problem, fill it in with a 0 to hold that place. for example,
if you were dividing x - 1 into 2x^3 + x - 5, you'd write it like this:
x - 1 ) 2x^3 + 0x^2 + 1x - 5
