Comcast Corporation is the largest cable television company, the second largest Internet service provider, and the fourth largest telephone service provider in the United States. Generally known for quality and reliable service, the company periodically experiences unexpected service interruptions. On January 14, 2009, such an interruption occurred for the Comcast customers living in southwest Florida. When customers called the Comcast office, a recorded message told them that the company was aware of the service outage and that it was anticipated that service would be restored in two hours. Assume that two hours is the mean time to do the repair and that the repair time has an exponential probability distribution.
a. What is the probability that the cable service will be repaired in one hour or less?
b. What is the probability that the repair will take between one hour and two hours?
c. For a customer who calls the Comcast office at 1:00 P.M., what is the probability that the cable service will not be repaired by 5:00 P.M.?

How do I do number 2 and 4 please help
Answer:
2: 176.8mm
4: ?
Step-by-step explanation:
2: 56 times 3.14 = 175.84 --> Nearest tenth: 176.8
4: I can't see the problem, sorry :(
Answer:
2. 2461.8
4. 86.6
Explanation:
your formula for area is pi×radius^2
you are using 3.14 for pi
and your radius is half way across the circle or half the diameter.
2. 3.14×(28)^2
3.14×784
=2461.8
4.This one shows the diameter so you have to divide it by 2 first.
10.5/2=5.25
radius=5.25
3.14×(5.25)^2
3.14x27.5625
=86.6

a) Which mapping diagram represents the relation?
Answer:
D
Step-by-step explanation:
1) remember that x indicates the independent variable, while y the dependent variable
2) remember that the first diagram represents the values of x, while the second the values of y
Mapping diagram A represent the number of tickets sold on that day. Therefore, option A is the correct answer.
The given set of ordered pairs are {(1,19), (2,23), (3,23), (4,29), (5,31)}.
What are relations in Math?In math, a relation defines the relationship between sets of values of ordered pairs. The set of elements in the first set are called domain which is related to the set of the element in another set, which is called range.
A mapping diagram consists of two parallel columns. The first column represents the domain of a function [tex]f[/tex], and the other column for its range. Lines or arrows are drawn from domain to range, to represent the relation between any two elements.
Diagram A represents the given ordered pair
Mapping diagram A represent the number of tickets sold on that day. Therefore, option A is the correct answer.

KM and NP are parallel lines.
Which angles are alternate exterior angles?
Answer:
<MLJ and <NOQ
Step-by-step explanation:
Alternate exterior angles are angles that lie outside of the two parallel lines that are cut across by the transversal line, and are also alternating each other along the transversal
Considering the image and the options given, <MLJ and <NOQ are exterior angles that alternate each other. Therefore, they are alternate exterior angles.

Two methods are proposed for testing a shipment of five items (call them A, B, C, D, and 13). In method 1, an inspector randomly samples two of the five items and tests to see whether either item is defective. In method 2, an inspector randomly samples one item and tests it; the remaining four items are sent to a second inspector who randomly samples one item and tests it. Suppose that only item A is defective in the shipment.
a. What is the probability that item A will be dis-covered by method 1?
b. What is the probability that item A will be dis-covered by method 2?
c. What general statement can you make regarding the effectiveness .of the two methods? Can your statement be extended to methods involving samples of more than two items?
Answer:
a-The probability that item A is discovered as a defective item by method 1 is 0.4
b. The probability that item A is discovered as a defective item by method 2 is 0.4
c-As the probability of detecting A as a defective item is same for the two methods, thus it can be stated that each of the methods is equally effective.
Step-by-step explanation:
a-
The first method where the inspector chooses two of the five items randomly, so the total pairs are as given below:
[tex]N_{total}=n(S_{total})\\N_{total}=n(\{AB,AC,AD,AE,BC,BD,BE,CD,CE,DE\})\\[/tex]
As the total experiments in the overall space is 10 so [tex]N_{total}[/tex] is 10.
As A comes in 4 of these experiments, thus the value of [tex]N_{A}[/tex] is 4.
So the Probability of A is given as
[tex]P(A)=\dfrac{N_{A}}{N_{total}}\\P(A)=\dfrac{4}{10}\\P(A)=0.4[/tex]
The probability that item A is discovered as a defective item by method 1 is 0.4.
b-
Now in order to find the probability of finding item A as defective by method 2, first consider the probability of not finding item A as defective.
This is given as
[tex]P(A)=1-P(A)'[/tex]
Here P(A)' is given as
[tex]P(A)'=P(A)'_{1^{st}}\times P(A)'_{2^{nd}}[/tex]
Here
P(A)'_1st is the probability that the first inspector fails to detect A as a defective item which is given as
[tex]P(A)'_{1^{st}}=1-\dfrac{1}{N_{total\ items}}[/tex]
Here N_total items is 5. so the equation becomes
[tex]P(A)'_{1^{st}}=1-\dfrac{1}{N_{total\ items}}\\P(A)'_{1^{st}}=1-\dfrac{1}{5}\\P(A)'_{1^{st}}=\dfrac{5-1}{5}\\P(A)'_{1^{st}}=\dfrac{4}{5}[/tex]
Similarly
P(A)'_2nd is the probability that the second inspector fails to detect A as a defective item which is given as
[tex]P(A)'_{2^{nd}}=1-\dfrac{1}{N_{total\ items}}[/tex]
Here N_total items is 4 as 1 item has already been checked. so the equation becomes
[tex]P(A)'_{2^{nd}}=1-\dfrac{1}{N_{total\ items}}\\P(A)'_{2^{nd}}=1-\dfrac{1}{4}\\P(A)'_{2^{nd}}=\dfrac{4-1}{4}\\P(A)'_{2^{nd}}=\dfrac{3}{4}[/tex]
So the main equation becomes
[tex]P(A)=1-P(A)'\\P(A)=1-(P(A)'_{1^{st}}\times P(A)'_{2^{nd}})[/tex]
Substituting the values give
[tex]P(A)=1-(P(A)'_{1^{st}}\times P(A)'_{2^{nd}})\\P(A)=1-(\dfrac{4}{5}\times \dfrac{3}{4})\\P(A)=1-\dfrac{3}{5}\\P(A)=\dfrac{5-3}{5}\\P(A)=\dfrac{2}{5}\\P(A)=0.4[/tex]
The probability that item A is discovered as a defective item by method 2 is 0.4.
c-
As evident from the above, that the value of probabilities for both the methods is same therefore the overall effectiveness of each of the methods is same.
