The midpoint divided a segment into two congruent lengths/segments.

So, QM = MR.

Set up the equation.

16 + x = 2(x+ 2)

16 + x = 2x + 4

12 + x = 2x

12 = x


Now, that you have the value of x, substitute it for the two equations.

QM = 16 + x

QM = 16 + 12

QM = 28


MR = 2(12+ 2)

MR = 2(14)

MR = 28


Find the whole length by of the line by adding the two segments. 28 × 2 = 56.

QR = 56

<h3>Mean and Measure of central tendency</h3>

By convention, the mean is a statistical measure of central tendency.

On this note, if the mean of a set of data values is 10, this means the data values have data points greater, equal and less than the mean value.
