What is the vertex from the equation y=x^2-4+7 a. y=(x-2)^2+3 b. y(x-2)^2-3 c. y=(x+2)^2+3 d. y=(x+2)^2-3

step-by-step explanation:

try remembering the steps

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
