x = 1.5 +/-√3.25.

Step-by-step explanation:

x^2 - 3x - 1 = 0

x^2 - 3x = 1

Completing the square:

(x - 1.5)^2 - 1.5^2 = 1

(x - 1.5)^2 = 1 + 2.25 = 3.25

x - 1.5 = +/-√3.25

x = 1.5 +/-√3.25

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
