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.

In order to average together values that match two different conditions in different ranges, an Excel user should use the Excel Average functions.<span>To calculate average in Excel,the powerful Excel Average functions will do the work behind the scene. </span>You use the AVERAGE function in Excel to return the average (arithmetic mean) of the specified cells. The different functions are : <span><span>Excel AVERAGE - calculate the mean of cells with numbers. </span><span>Excel AVERAGEA - find an average of cells with any data. </span><span>Excel AVERAGEIF - average cells based on a given criterion. </span><span>Excel AVERAGEIFS - average cells that match several criteria.</span></span>
Answer:
By using dependency injection, create the adapter to adapt both the DataViz and the UberStats interface as expected.
Explanation:
Adapters are used in Objected-oriented programming to run or convert the output of one class object to another. The DataViz class currently uses the SuperStats class as an adaptee to get and output statistical results.
Write a new code from the scratch is tedious, so, the UberStats class dependencies are injected in the adapter and the DataViz and UberStats class functionalities can be experimented with.
Power point is the most “professional”, if that what your asking.
