110 = 5x + 3y     (yet x + y = 30)
Therefore the only explanation would 10 kids bought lunch and 20 packed because....
10 + 20 = 30       AND     5 * 10 = 50     3 * 20 = 60       60 + 50 = 110

levacccp [35]

Answer:

The correct answer is letter "C": what-if analysis.

Explanation:

A what-if analysis is a study an individual or company makes about a certain number of events where variables are changed to determine what the outputs would be. This approach is normally implemented when there is limited information from where to make a concise decision. Then, individuals have to outline all the possible results to find out what their risks are.

Software like Microsoft Office Excel facilitates the implementation of what-if analysis.

Your answer to this is:

\sf{= \frac{1}{2} \: + \frac{2}{1 \: + \: x^2} \: + \: \frac{1}{1 \: + \: x^4} \: + \: \frac{2^1^0^0}{1 \: + \: x^2^0^0}

<h2>→ <u>EXPLANATION :-</u></h2>

<u />

<u />\sf{= \frac{1}{2} \: + \frac{2}{1 \: + \: x^2} \: + \: \frac{1}{1 \: + \: x^4} \: + \: \frac{2^1^0^0}{1 \: + \: x^2^0^0} \: (1)

\sf{Apply \: rule:} \: (a) = a

\sf{(1) = 1

\sf{= \frac{1}{2} \: + \frac{2}{1 \: + \: x^2} \: + \: \frac{1}{1 \: + \: x^4} \: + \: \frac{2^1^0^0}{1 \: + \: x^2^0^0} \: ^. \: 1

\sf{\frac{1}{1 \: + \:1} = \frac{1}{2}

\sf{\frac{2^1^0^0}{1 \: + \: x^2^0^0} ^.^ \: 1 \: = \: \frac{2^1^0^0}{1 \: + \: x^2^0^0}

\sf{= \frac{1}{2} \: + \frac{2}{1 \: + \: x^2} \: + \: \frac{1}{1 \: + \: x^4} \: + \: \frac{2^1^0^0}{1 \: + \: x^2^0^0}
