[20pts] A service facility charges a $20 fixed fee plus $25 per hour of service up to 6 hours, and no additional fee is charged

for a service visit exceeding 6 hours. Suppose (for now) that the service time τ is equally likely to be any time in [0, 10] hours. (Note that τ is a continuous random variable.) Let X represent the cost of service in the facility. We would like to set up the probability density function (PDF) and the cumulative distribution function (CDF), then use them to analyze service fees.

Answer:

Step-by-step explanation:

The function of a continuous random variable, whose integral over an interval provides the likelihood that the value of the variable is just inside the same interval while The cumulative distribution function (FX) provides the possibility that the random variable X is not up to or equal to a particular amount x. the formula for calculating it is: Summing the values for every one of the outcomes less than or equal to x will give the solution.

maria [59]

(1,\ 1)\to x_1=1,\ y_1=1\to x_1=y_1\\\\(5,\ 5)\to x_2=5,\ y_2=5\to x_2=y_2\\\\\text{Therefore we have the equation}\ y=x\\\\\text{subtract y from both sides}\\\\\boxed{x-y=0\to\boxed{B}}\to\boxed{y-x=0\to\boxed{A.}}\\\\Answer:\ C.\ -x-y=0

Help me please I need to do this
Blizzard [7]

Consider the attached tree.

You start from the root, and with each level you create a sub-branch for each of the choices you have.

So, the root has two children, white and multigrain bread.

Each of those children has three children, because you have three meat choices

Each of those children has two children, because you have two cheese choices.

Then, you identify all the sandwiches by choosing a leaf, and read the label that lead you there.

For example, leaf number 4 represents a sandwich with white bread, turkey and provolone.

We need the height of the cone
what we do is we know that when height is 10, V=something, so solve for the diameter is at that point and compare it to 24, the full height
sorry if confusing

V=(1/3)hpir^2
when h=10
160pi/3=1/3(10)pir^2
ties 3 both sides
160pi=10pir^2
divide by 10pi
16=r^2
sqrt both sides
r=4

at that point, the radius is 4
the real radius of the ful is 24/2=12
4/12=1/3
it is 1/3 full

if 1/3=160pi/3cm
2/3=320pi/3cm^3

needs 320pi/3 cm^3
