What is the value of n in the equation below? StartFraction a Superscript n Over a cubed EndFraction = a Superscript 9 3 6 12 27 How do the respiratory and circulatory systems work together to make gas exchange possible?

n

step-by-step explanation:

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
