Answer:
The expression in python is: x.isdigit()
Explanation:
Given
Character variable x
Required
Expression that evaluates if x is decimal or not
The expression in python is: x.isdigit()
If x is digit 0 - 9, x.isdigit() will equal True
Otherwise, it will equal False
The testing phase of the SDLC stands as one of the most important. It exists impossible to deliver quality software without testing.
<h3>
What is SDLC?</h3>
The Software Development Life Cycle (SDLC) exists as a structured process that facilitates the production of high-quality, low-cost software, in the shortest possible production time. The objective of the SDLC stands to produce superior software that satisfies and exceeds all customer expectations and demands.
In systems engineering, information systems, and software engineering, the systems development life cycle, also directed as the application development life cycle, exists as a process for planning, designing, testing, and deploying an information system.
The testing phase of the SDLC stands as one of the most important. It exists impossible to deliver quality software without testing. There exists a wide variety of testing required to measure quality:
- Code quality
- Unit testing (functional tests)
- Integration testing
- Performance testing
- Security testing
The best method to ensure that tests exist run regularly, and are never skipped for expediency, stands to automate them. Tests can be automated using Continuous Integration tools, like Codeship. The output of the testing phase lives improved software, ready for deployment to production circumstances.

Answer:
Checks if it is a multiple of 3 and 5
Explanation:
Its an if statement using modulus division to check for a remainder. It checks if a number is a multiple of 3 AND 5. (&& and & both mean and in Java).
If the remainder of both is 0 then that means the mystery number is a multiple of both 3 and 5.
Answer:
The 3 band resistor does not specify the tolerance.
Ususally this means the tolerance is 20%, which is not great.
Explanation:
The last band is typically the tolerance band, i.e., the lower the tolerance the more accurate the value as indicated by the other bands. In case of a 3 band code, there is no tolerance specified and you have to assume the default of 20%.
Answer:
1080 x 1920
800 x 600
Explanation:
These are the screen sizes that you can find in the list of the screen sizes, which can be easily found in the document that lists all the screen sizes. You will certainly find the 1080 x 1920 and also the 800 x 600, however, you will not find the 320 x 240 and 800 x 600. The last two are the standard screen sizes and hence are not the correct options. The correct options are as listed above.
