Which set of points represents a function? a. (-5, -4), (-4,-3), (-3, -2), (-2, -1) b. (-6,2), (6,-2), (-5, 3), (-5,-3) c. (8, -1), (8,2), (8,-3), (8,4) d. (1,3), (-4,4), (3,-2), (1,0) can someone tell me how they got the answer?

x = -2

y = 848

step-by-step explanation:

plug in the numbers

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
