Can someone me with my homework
ignore the bottom question

1. x = 1    2. x = -30   3. x = -2   4. x = 15   5. x = 7, y = 11   6. x = 4, y = 1  

7. x = 1/2, y = 25/5   8. x = 1/4, y = 11/2

hope this helps :3

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 %
