h(t)= -8t2+40t + 5, 1.What is the initial height of the ball when it is thrown? 2.What is the maximum height of the ball? 3.How many seconds does it take before the ball reaches its maximum height? 4. After how many seconds will the ball hit the ground (approximate time rounded to the nearest tenths place)? 5.What is the height of the ball at 4 seconds? 6. When will the ball reach a height of 53 feet? 7. What is the domain of the function? 8. What is the range of the function?

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 %

x = 12

y = 1
