For the following equation, what value of x would make a = 4?
х
- +7= 9
a

the solution is 12x-6y

you would need to know all the numbers that are on there

step-by-step explanation:

the answer is a if my teacher taught me correct

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 %
