A hotel has three elevators. One of them is a freight elevator. When pressing the button, one of the elevators randomly services your floor. If you use the elevators five times, what is the probability that you use the freight elevator exactly two times?​

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

y > 1/3x

y < = -x + 4

hope this : )

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
