These are the answers to the questions
Z-score for 30 = (30 - 25) / 5.8 = 0.8621
z-score for 20 = (20 - 25) / 5.8 = -0.8621
:
Note find probabilities from z-tables
:
Probability ( 20 < X < 30 ) = 0.8051 - 0.1949 = 0.6102
The answer would be -13 54/55
Point c is quadrant 2,point T is quadrant 1,point R is x axis , point h is quadrant 3
