Statement two and three is correct.
Statement 1 is incorrect. A relative reference changes when a formula is copied to another cell while Absolute references remain constant. However, it is safe to say that an absolute address can be preceded by a $ sign before both the row and the column values. It is designated by the addition of a dollar sign either before the column reference, the row reference, or both. Statement C is also correct. A mixed reference is a combination of relative and absolute reference and the formula (= A1 + $B$2) is an example of a mixed cell reference.
Answer: Supermarket bar code scanners and Voice-activated telephone menus are not instances of artificial intelligence
Explanation:
(a)Supermarket bar code scanners are only able to read the code however they are not able to perform any kind of machine learning techniques to be able to learn a sequence from the codes. As machine learning is a important part of artificial intelligence (AI) so they are not instances of AI. Similarly for Voice-activated telephone menus they could only display and cannot perform any intelligent task.
Web search engines and Internet routing algorithms are very dynamic and intelligent in processing and retrieving information to the end user.
So they are instances of AI.
I believe the answer is d
8 bits = 1 byte
10 Mbps = 10/8 M bytes per second
1 frame = 50 bytes
Frame rate = 10 M / (8 x 50) = 10 M / 400 = <em>25,000 frames per second</em>
========================
If each frame has an error probability of 0.004, then (0.004 x 25,000) = 100 frames per second are damaged.
1 hour = 3,600 seconds.
100 damaged frames per second = (100 x 3,600) = <em>360,000 damaged frames per hour.</em>
