Answer:
7
Explanation:
Given the codes as follows:
- j = i = 1
- i += j + j * 5
- print("What is i?", i)
In line 1, the value of 1 is assigned to variable i and then the variable i is assigned to variable j. This means j will hold the value of 1 as well.
In line 2, j will be multiplied with 5 prior to the addition with j itself. So, j + j * 5 -> 1 + (1 * 5) -> 1 + 5 -> 6
Next, value of 6 will be added with i. i = i + 6 -> i = 1 + 6 -> 7#
Eventually, value of 7 will be printed out (Line 3).
Answer:
I believe the translation would be "get out", but I'm not sure.
Explanation:
Answer: Choice A) Storing customers' package tracking information
I'm assuming we're talking about a very large company. You could use a spreadsheet, but a database is more ideal since spreadsheets bog down at a certain point when there are too many data items in it. Databases are more dynamic and allow for better scalability. The term "scalability" means it can be easily grown or shrunk depending on the needs of the client.
Choice B is false because you could use a spreadsheet to show the family's budget. The budget isn't too big and the number of items to list aren't numerous, so that's why a spreadsheet is ideal. A database would be overkill for the family's budget. The same applies to choice C and D as well. So we can rule out choices C and D also.
Answer:
Explanation:
You can detect credit card fraud by identifying charges you didn't make or authorize. Another sign can come through the mail with your statements, and that's bills for products or services you didn't buy. You could even get a bill for a credit card statement on a card you didn't open.
Answer:
Charles Babbage, (born December 26, 1791, London, England—died October 18, 1871, London), English mathematician and inventor who is credited with having conceived the first automatic digital computer.
Explanation:
The idea of mechanically calculating mathematical tables first came to Babbage in 1812 or 1813. Later he made a small calculator that could perform certain mathematical computations to eight decimals. Then in 1823 he obtained government support for the design of a projected machine, the Difference Engine, with a 20-decimal capacity. The Difference Engine was a digital device: it operated on discrete digits rather than smooth quantities, and the digits were decimal (0–9), represented by positions on toothed wheels rather than binary digits (“bits”). When one of the toothed wheels turned from nine to zero, it caused the next wheel to advance one position, carrying the digit. Like modern computers, the Difference Engine had storage—that is, a place where data could be held temporarily for later processing.
