Given A=1101 and B=1001. What is the result of the boolean statement: A
AND B​

Answers

Answer:

B  (1001)

Explanation:

The AND operator gets you 1's where there are 1's in both inputs. So if you would "overlay" the two binary values, only 1001 remains.

what was his beliefs?

Answers

A belief is an attitude that something is the case, or that some proposition about the world is true.[1] In epistemology, philosophers use the term "belief" to refer to attitudes about the world which can be either true or false.[2] To believe something is to take it to be true; for instance, to believe that snow is white is comparable to accepting the truth of the proposition "snow is white". However, holding a belief does not require active introspection. For example, few carefully consider whether or not the sun will rise tomorrow, simply assuming that it will. Moreover, beliefs need not be occurrent (e.g. a person actively thinking "snow is white"), but can instead be dispositional (e.g. a person who if asked about the color of snow would assert "snow is white").[2]

There are various different ways that contemporary philosophers have tried to describe beliefs, including as representations of ways that the world could be (Jerry Fodor), as dispositions to act as if certain things are true (Roderick Chisholm), as interpretive schemes for making sense of someone's actions (Daniel Dennett and Donald Davidson), or as mental states that fill a particular function (Hilary Putnam).[2] Some have also attempted to offer significant revisions to our notion of belief, including eliminativists about belief who argue that there is no phenomenon in the natural world which corresponds to our folk psychological concept of belief (Paul Churchland) and formal epistemologists who aim to replace our bivalent notion of belief ("either we have a belief or we don't have a belief") with the more permissive, probabilistic notion of credence ("there is an entire spectrum of degrees of belief, not a simple dichotomy between belief and non-belief").[2][3]

Beliefs are the subject of various important philosophical debates. Notable examples include: "What is the rational way to revise one's beliefs when presented with various sorts of evidence?"; "Is the content of our beliefs entirely determined by our mental states, or do the relevant facts have any bearing on our beliefs (e.g. if I believe that I'm holding a glass of water, is the non-mental fact that water is H2O part of the content of that belief)?"; "How fine-grained or coarse-grained are our beliefs?"; and "Must it be possible for a belief to be expressible in language, or are there non-linguistic beliefs?".[2]

Please use the tables in the flights database. Your deliverable should include a single SQL query that I can run against a "fresh copy" of the tables in the flights database.
1. Write a script to select all data from the planes table.
2. Update the planes table so that rows that have no year will be assigned the year 2013. (missing values will display as NULL).
3. Insert a new record to the planes table with the following values:
Tailnum: N15501
Year: 2013
type: Fixed wing single engine
Manufacturer: BOEING
Model: A222-101
Engines: 3
Seats: 100
Speed: NULL (notice this is not a text value but truly the absence of any value: "empty". As such, don't use single or double quotes around NULL when inserting this value).
Engine: Turbo-fan
4. Delete the newly inserted record on step 3.

Answers

Answer:

The scripts are:

1. SELECT * FROM planes

2. UPDATE planes SET YEAR = 2013 WHERE year IS NULL

3. INSERT INTO planes (Tailnum, Year, type, Manufacturer, Model, Engines, Seats) VALUES ('N15501',2013,'Fixed wing single engine', 'BOEING', 'A222-101',3,100,NULL)

4. DELETE FROM planes WHERE Tailnum = 'N15501'

Explanation:

1. SELECT * FROM planes

To select all from a table, use select * from [table-name]. In this case, the table name is planes

2. UPDATE [tex]planes\ SET[/tex] YEAR = 2013 WHERE year IS NULL

To do this, we use the update query which is as follows:

UPDATE [table-name] SET [column-name]= [value] WHERE [column] IS NULL

So: the above query will update all YEAR column whose value is NULL to 2014

3. INSERT INTO planes (Tailnum, Year, type, Manufacturer, Model, Engines, Seats) VALUES ('N15501',2013,'Fixed wing single engine', 'BOEING', 'A222-101',3,100,NULL)

To insert is very straight foward.

The syntax is:

INSERT INTO [table-name] (column names) VALUES (values)

4. DELETE FROM planes WHERE Tailnum = 'N15501'

To do this, we use the update query which is as follows:

DELETE FROM [table-name] WHERE [column] = [value]

So: The above query will delete the entry in (3) above

Explanation:

Select the correct statement(s) regarding the signal-to-noise ratio (SNR).
A. SNR represents the ratio of transmit signal power over the noise power of all sources including thermal, impulse, IM, CCI, and crosstalk noise.
B. the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.
C. the noise power, in the signal-to-noise ratio, occupies a narrow band in the frequency domain.
D. all of the above are correct statements.

Answers

Answer:

B. the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.

Explanation:

Sound can be defined as mechanical waves that are highly dependent on matter for their propagation and transmission. Sound travels faster through solids than it does through either liquids or gases.

Signal-to-noise ratio (SNR) is simply the ratio of signal power to noise power or the ratio of desired information to the undesired signal. SNR doesn't have a unit i.e it is a unitless quantity.

Generally, the higher the signal-to-noise ratio (SNR), the better would be the quality of a signal.

Additionally, a negative signal-to-noise ratio (SNR) in decibel form simply means that the signal power is lesser than the noise power.

Hence, the correct statement regarding the signal-to-noise ratio (SNR) is that the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.

Note: noise can be defined as an unwanted disturbance or undesired signal present in an electrical signal.

explain five unique features of word processor

Answers

Explanation:

Typing, editing and printing different types of document . Formatting text , paragraph , pages for making attractive document .Checking spelling and grammar of document for making it error free.Inserting and editing picture , objects,etc. Adding watermark, charts,quick flip , etc

1) Easy Typing : In MS Word, typing is so easy because :

we need not click enter button after the end of a line as in case of type writer. The word processor itself takes the matter to the next line of the document. This facility is called word wrapping.There is no limit for typing the matter in word processing. You can type the matter continuously without resorting to new page or file. But in a type writer, if you complete a page, you have to take another blank page and start typing.You can easily rectify mistakes as the typed matter appears on the screen.

2) Easy : The document so typed can be stored for future use. The process of storing is called saving. We can preserve the document for any number of years in word processing.

3) Adding, Removing and Copying Test : Documents can be modified easily in MS Office. We need not strike off any word as in the case of type writer. We can easily place a new word in place of existing one. The new word or paras will automatically be adjusted in the place of deleted or modified text. We can also copy a part or whole of the matter from one file or document to another document.

4) Spell Check of words : The spellings of words in the document can be rectified automatically. We can find alternative words to our typed words. Not only that, even the grammatical errors can also be rectified in word processor.

5) Change the Style and Shape of Characters and Paragraphs : The documents in word processor can be made attractive and appealing because the shape and style of characters or letters in the documents can be changed according to our requirements. You can even change the gap between one line and other line in the document. This process is called line spacing. Not only the lines but also paragraphs can be aligned to make it more appealing to the readers. This facility is called alignment in word processing.

Your program should include the following four functions:
check_length - This function should accept a password to evaluate as a parameter and should return a score based on the length of the password. A password that is less than 8 characters long gets a length score of 1. If it is between 8 and 11 characters long (inclusive), it gets a length score of 2. A password that is 12 characters or longer gets a length score of 3.
check_case - This function should accept a password to evaluate and return a case score of 1 or 2. If the letters in the password are all uppercase or all lowercase, the case score should be a 1. If there is a mix of uppercase or lowercase letters (or if there are no letters at all), it gets a case score of 2.
check_content - This function should accept a password to evaluate and return a content score. If the characters are all alphabetic characters, the content score is 1. If the characters include any numeric digits (either all numeric or a mix of letters and digits), the content score is 2. If there are any other types of characters (such as punctuation symbols), the content score is 3.
main - This function represents the main program. It accepts no parameters and returns no value. It contains the loop that allows the user to process as many passwords as desired. It function calls the other functions as needed, computing the overall score by adding up the scores produced by each function. All output should be printed in the main function.

def check_length(pwd):

   lent = len(pwd)

   if lent < 8:

       return 1

   elif lent >=8 and lent <= 11:

       return 2

   else:

   elif(pwd.isalnum()):

       return 2

   else:

       return 3

   

if __name__ == "__main__":

   main()

Explanation:

The main begins here

def main():

This prompts the user for password

   pwd = input("Password: ")

This calls the check_length function

   print("Length: "+str(check_length(pwd)))

This calls the check_case function

   print("Case: "+str(check_case(pwd)))

This calls the check_content function

   print("Content: "+str(check_content(pwd)))

The check_length function begins here    

def check_length(pwd):

This calculates the length of the password

   lent = len(pwd)

If length is less than 8, it returns 1

   if lent < 8:

       return 1

If length is less than between 8 and 11 (inclusive), it returns 2

   elif lent >=8 and lent <= 11:

       return 2

If otherwise, it returns 3

   else:

       return 3

The check_case function begins here    

def check_case(pwd):

If password contains only uppercase or only lowercase, it returns 1

   if(pwd.isupper() or pwd.islower()):

       return 1

If otherwise, it returns 2

  else:

       return 2

The check_content function begins here

def check_content(pwd):

If password is only alphabet, it returns 1

   if(pwd.isalpha()):

       return 1

If password is only alphanumeric, it returns 2

   elif(pwd.isalnum()):

       return 2

If otherwise, it returns 3

   else:

       return 3

This calls the main function    

if __name__ == "__main__":

   main()
