Which of the following is equivalent to the square root of -80? a: -4i sqrt 5 b: 16i sqrt 5 c: 4i sqrt 5 d: 2i sqrt 5

the answer to your problem is C 4i sqrt 5

Step-by-step explanation:

Starting out with the square root of -80 you simplfy the radical by breaking the radicand (the number under the inclusion bar of the radical sign) up into the product of the known factors giving you your answer.

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

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
