-2.4
Step-by-step explanation:
maybe... i am 99.99% sure
The answer is true I have had this question before

Step-by-step explanation:
We start by applying the Pythagorean theorem to the ladder, with its length L as the hypotenuse:

where x is the vertical distance from the top of the ladder to the ground and y is the horizontal distance from the bottom of the ladder to the wall. Taking the derivative of the above expression with respect to time, we get

Solving for dx/dt, we get

We know that

when x = 6 ft. So the rate at which the top of the ladder is going down is


The negative sign means that the distance x is decreasing as y is increasing.
Sum greater than 9 from the Sample Space are:
{(4,6),(5,5),(5,6),(6,4),(6,5),(6,6)}
so, in total 6 out of total 36 combinations have a sum greater than 9
So, 

Probability(sum>9)=0.167
