Evaluate f(3) for the follow f(x)=x-5 f(3) =

f(3) = - 2

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x) , that is

f(3) = 3 - 5 = - 2

If , f(3) = -2

Step-by-step explanation:

We are given and we need to find f(3)

For finding f(3), we put x= 3 in the given function.

Putting x=3

So, if , f(3) = -2

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
