PLEASE HELP 20 POINTS

B

Step-by-step explanation:

Point M is the bisector of the line segment. Because a bisector cuts something to 2 equal parts, you can set 2x + 6 = 5x - 9. You can solve for X, and plug it back into the equation to get the length of the line segment.

How to get x:

2x + 6 = 5x - 9

15 = 3x

5 = x

How to get the line segment length:

2(2*5 + 6) = 32

(You multiply by 2 because finding 1 side of the line segment gives you the other in the case there is a bisector)

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
