Solve the quadratic equation.

8x^2 + 16x + 8 = 0

a)
1

b)
-1

c)
1 and 8

d)
1 and -1

-1

Step-by-step explanation:

8(-1)^2+16(-1)+8=0

8-16+8=0

0=0

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
