Suppose that the functions f and g are defined for all real numbers x as follows.
f(x) = x - 4
g(x) = 3x +1
Write the expressions for (f•g)(x) and (f+g)(x) and evaluate (f-g)(-1)

yes

step-by-step explanation: it is d

what is the model?

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
