Answer:

Explanation:

Keywords: Keywords are those words which have special meanings in QBASIC. Keywords are formed by using characters of QBASIC characters set. Keywords are statements, commands, functions (built in functions) and names of operators. The keywords are also called Reserved Words. Some reserved words are CLS, REM, INPUT, LET, PRINT, FOR, DO, SELECT, ASC, SQR, LEN, and INT.
Constants: They are divided into:

Numeric constants: include all numbers (real, integer, not real,...)

Character constants: include all character sete (letters, digits, symbols) between two double quotation marks e.g. "BASIC", "the width is 83" etc.

3. Variables: A variable is a name which can hold or contain a value.

Write a query that returns the Genres that I have purchased the most tracks of. I only care about genres that I've purchased at

Murljashka [212]

Answer:

SQL Query

///////////////////////////////////////////////////////////////////////////////////////////////////

select Genre_Name, Number_Purchased from Genre

INNER JOIN Tracks on Genre.Genre_Name = Tracks.Genre_Name

WHERE Number_Purchased >= 10 AND Tracks.price >= 1

ORDER BY Number_Purchased ASC;

Explanation:

First off, I selected the required columns from Genre Table.

Then I inner joined Genre table with Tracks table, to get the price of tracks of the corresponding Genres.

Then the required Where conditions are written, which includes one from the Tracks table.

Finally, the Order by statement is written by Number_Purchased column in ascending (ASC) order.

g Boolean Algebraic properties _____. a. are used to make boolean expressions more complicated b. are used to convert a Boolean

vesna_86 [32]

Answer:

c. can lead to a simpler expression and thus a simpler circuit.

Explanation:

Boolean logic refers to a theory of mathematics developed by the prominent British mathematician, called George Boole. In Boolean logic, all variables are either true or false and are denoted by the number "1" or "0" respectively; True = 1 or False = 0.

Also, Boolean logic allow users to combine keywords with Boolean operators (quotes, AND, OR, near/n) to give a more personalized and relevant search results.

There are five (5) main Boolean Algebraic properties and these includes;

I. Commutative property: it applies to both multiplication and addition.

For addition; A + B = B + A
For multiplication; A.B = B.A

II. Associative property: it applies to both multiplication and addition.

For addition; A + (B + C) = (A + B) + C
For multiplication; A(BC) = (AB)C

III. Distributive property: it is formed using the product of a sum.

A(B + C) = AB + AC

IV. Complement property: it involves a variable and its complement.

For addition: A + A' = 1
For multiplication; A.A' = 0

V. Identity property:

For addition; A + 0 = A
For multiplication; A.1 = A

In digital electronics, Boolean expressions are used to represent circuits which comprises of Boolean operations and as such simplifying any logic expression without changing or altering any of it's functionalities and properties based on given operations or variables.

Hence, Boolean Algebraic properties can lead to a simpler expression and thus a simpler circuit.
