1. if y varies directly as x, and y=40 when x=16, find y when x=30 answer?

If y = 40 when x = 16 that means y is (40/16) time greater than x.

So, if x = 30, y = (40/16) x 30 Which equals 75.

If x = 30, y = 75. Hope This Helps :)

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 %
