What is the equation of the following graph?

The given graph represents a downward parabola with centre (h,k) = (2,-4) and it passes through (8,-7) .

Here we use the following formula

So the required equation is

or

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 %

4+4+2x

or

2x+8
