A technician services mailing machines at companies in the Phoenix area. Depending on the type of malfunction, the service call can take 1.2, 2.3, 3.3, or 4.1 hours. The different types of malfunctions occur at the same frequency. If required, round your answers to two decimal places. Develop a probability distribution for the duration of a service call. Duration of Call x f(x)
1.2
2.3
3.3
4.1
Consider the required conditions for a discrete probability function, shown below.
f(x)>/=0 (5.1)
summation f(x)=1 (5.2)
Does this probability distribution satisfy equation (5.1)?
Does this probability distribution satisfy equation (5.2)?
What is the probability a service call will take 3.3 hours?
A service call has just come in, but the type of malfunction is unknown. It is 3:00 P. M. and service technicians usually get off at 5:00 P. M. What is the probability the service technician will have to work overtime to fix the machine today?

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

my guess is
