Suppose that the functions g and h are defined for all real numbers x as follows. g(x) = x-2
h(x) = 4x+4
Write the expressions for (g-h) (x) and (g+h) (x) and evaluate (g. h)(3).
(g- h)(x) =
(g+h)(x) =
(g•h)(3) =

answer: a

step-by-step explanation:

44

step-by-step explanation:

x+14

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
