A toy cannon ball is launch from a cannon on top of a platform the equation h(t)= -5t + 14t + 2 gives the height h, in meter, of the ball t seconds after it is launched. A) determine if the ball reaches a height of 14 meters. explain your answer.

B) how long is the ball in the air?

A) No, because it only reaches 11.8 meters B) 2.9362 seconds :)

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 %
