Answer:
- Scenario
- Use case
- Scenarios
- Scenarios
- Use case
Explanation:
A <u>scenario</u> is an actual sequence of interactions (i.e., an instance) describing one specific situation; a <u>use case</u> is a general sequence of interactions (i.e., a class) describing all possible <u>scenarios</u> associated with a situation. <u>Scenarios</u> are used as examples and for clarifying details with the client. <u>Use cases</u> are used as complete descriptions to specify a user task or a set of related system features.
Answer:
See Explanation Below
Explanation:
Given
S → aSb | bY | Y a
Y → bY | aY | ε
Giving a simple description of L(G) in English. The description is as follows;
This means that L(G) contains a string of a's and b's such that the following are true;
1. the string starts with n a’s and m b’s, where n and m can be zero, but not at the same time,and at least one of option 2 and option 3
2. and has any number of a’s or b’s followed by an a
3. ab followed by any number of a’s and b’s
Note that n and m represent numerical digits
Using the description to give a CFG for L(G), the complement of L(G) is written as L'(G)
L'G are elements not in L(G) and they are
L'(G) =a^n b (a∪b) * b^n ∪ a^n (a∪b) * ab^n
Explanation:
Atomic bomb, also called atom bomb, weapon with great explosive power that results from the sudden release of energy upon the splitting, or fission, of the nuclei of a heavy element such as plutonium or uranium.
The probability that the error occurred when Engineer 2 made the mistake is 0.462 on the other hand the probability that the error occurred when the engineer 1 made the mistake is 0.538
Explanation:
Let denote the event that the 1st engineer does the work.so we write
=0.7
Let denote the event that the 2nd engineer does the work .So we write
=0.3
Let O denote the event during which the error occurred .so we write
=0.02(GIVEN)
=0.04(GIVEN)
- The probability that the error occurred when the first engineer performed the work is
- The probability that the error occurred when the first engineer performed the work is
Now we need to find when did the error in the work occur so we will compare the probability of the work done by <u>engineer 1 </u>and <u>engineer 2 </u>
<u></u>
<u>lets find the Probability of the Engineer 1</u>
<u>Using Bayes theorem,we get</u>
<u></u>
<u></u> =0.02*0.7/0.02*0.7+0.04*0.3 = 0.014/0.026=0.538
<u>lets find the Probability of the Engineer 2</u>
<u></u> =0.04*0.3/0.02*0.7+0.04*0.3=0.012/0.026=0.462
Since ,0.462<0.538 so it is more prominent that the Engineer 1 did the work when the error occurred
Technician b is correct because the left rear brake drum is scored, but the right rear drum looks as good as new then both sides should be remachined to a similar diameter.
A brake drum is a revolving cylinder-shaped component that is friction-activated by a set of shoes or pads pressing outward against it. Drum brakes are brakes where shoes are pressed against the inner surface of the drum. Drum brakes are frequently used at the rear. Compared to disc brakes, these brakes have more parts and are more difficult to maintain, but they cost less to make and are simple to add an emergency braking mechanism. The front and rear brakes are standard equipment on all automobiles. Your car may have a "disc brake" system on all four wheels, a "drum brake" system on all four wheels, or a combination of the two. Typically, the front brakes of your car have a disc system, and the rear brakes have a drum system.
