Which of the following equations has a slope of 1/2 and a y-intercept of 9? * A. y = 1/2x + 9
B. y = 9x + 1/2
C. 9x + y = 1/2
D. 1/2x + y = 9

step-by-step explanation:

is only a line? i think so

step-by-step explanation:

b and c

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
