6 NAND gates are needed to construct this line decoder when a 2x4 line decoder with enable is implemented using nand gate only.
What is NAND gate?
The NAND gate is a hybrid of the AND and NOT gates. They are linked in a cascade fashion. It is also known as the Negated And gate. Only when their outputs are high or true does the NAND gate provide a false or low output. The NAND gate is necessary because it is used to implement various types of boolean functions.
The NAND gate has the functional completeness property. The NAND gate's function completeness means that it can be used to implement any type of gate. It functions as an OR, NOR, and AND gate.

Answer:
because it was originally given to humans (himan computers) who performed numerical calculations using mechanical calculators.The term was later given to mechanical devices as they began replacing human computers.
Answer:
b- Cited,then refuted
Explanation:
Citation enhances persuasion of information sources.
Refutation means understanding the viewpoint of the opposition and then countering it by providing respective evidence or by finding mistakes in the logic of the opposition's argument.
Answer:
B
Explanation:
im pretty sure thats the answer
Answer:
The correct option is D = regionNumber
Explanation:
In this scenario we want to know customers who owe more than $1000 each, in each of 12 sales regions. And the customer data variables include name, zip-code, balanceDue and regionNumber; based on the customer data variables names and zip-code will not really affect our output. It is based on balanceDue that we increment the number of customer owing in a particular region (regionNumber).
Therefore, we would add 1 to an array element whose subscript would be represented by regionNumber since we are interested to know the number of customer owing in each of the 12 sales regions.
