An airplane flies at an altitude of y=2 miles toward a point directly over an observed. The speed of the plane is 400 miles per hours find the rate (In radius per hour) at which the angle of elevation 0=30° ,0=60°, and 0=75°

we don't have enough info to solve this

2/3

step-by-step explanation:

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 %
