y=5x+20

Step-by-step explanation:

m=5

x=5

y=-5

y=mx+b

Substitute:

-5=5(5)+b

-5=25+b

b=20

Substitute:

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 %
