What is the range of this data set? 2.5, 6.1, 9.7, 11.4, 17.5, 20.2, 1.1, 12.6, 18.8

16.3

17.7

18.8

19.1

19.1

Step-by-step explanation:

Range = Maximum value - minimum value

          = 20.2  - 1.1

          = 19.1

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
