line a: y=-2/3+2 line b:y=3/2+9 line a and line b are: parallel, perpendicular, Neither, or Same line?

Perpendicular.

Step-by-step explanation:

Parallel lines have the same slope. Perpendicular lines have opposite slopes.

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

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
