Given the second order initial value problem y'' + y = 38(t – 2), y(0) = 1, y (0) = -3 let y(s) denote the laplace transform of y. then y(s) = taking the inverse laplace transform we obtain y(t) =

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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
