An airline gathers data on late departures and early arrivals over a month. it finds that the probability of a late
departure is 12 percent, the probability of an early arrival is 27 percent, and the probability of both a late departure
and an early arrival is 4 percent. which equation shows how to correctly calculate the probability of a late departure
or an early arrival?
p(late departure or early arrival) = 0.12 + 0.04
plate departure or early arrival) = 0.12 +0.27
p(late departure or early arrival) = 0.12 +0.27 - 0.04
sllate departure or early arrival) = 0.27 +0.04 - 0.12

p(late departure or early arrival) = 0.12 + 0.27 - 0.04

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
