Suppose card G extended out to 0 and 8 what would be the effect on the Standard deviation?

Hence Proved, AB=26

Step-by-step explanation:

Given: Segment AB = x + 16, Segment BC = 4x + 11, Segment AC = 77

To Prove: AB = 26

ABC is a col linear point as shown in diagram.

Sum of distance between two point is equal to length of line.

AB+BC=AC

where, AB=x+16 and BC=4x+11 , AC=26

Put x=10 into AB=x+16

AB=10+16 = 26

Hence Proved, AB=26
