I really need help on this

let: f(x)=x+1 and g(x)=x^2-2

find: f(x)•g(x)

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

a) 7x=7

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 %
