Aball is thrown from a height of 40 meters with an initial downward velocity of 10 m/s. the balls height h (in meters) after t seconds is given by the following.

h = 40 - 10t - 5t^2

how long after the ball is thrown does it hit the ground?

round to nearest hundredth

it would be 6xy and -16xy.

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 %
