Help please? A system of linear equations is graphed. Which ordered pair is the best estimate for the solution to the system? A. (0,7) B. (-4, 2 1/2) C. (0,-2) D. (-4 1/2, 2 1/2)

B. (-4, 2½)

Step-by-step explanation:

The lines intercept at the point -4 on the x-axis and 2½ on the y-axis

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
