Add a meeting six people each one another by shaking hands. If each person must shake hands once with every other person in the
Phantasy [73]

The number of handshakes is the number of ways 6 objects can be selected 2 at a time.

.. C(6,2) = 6·5/(2·1) = 15


The appropriate choice is

... C) 15


_____

Consider that each person can shake hands with 5 others. That's a total of 6*5 = 30 handshakes, but it counts both A shaking with B and B shaking with A. If each pair of persons only shakes hands once, the number of handshakes is 30/2 = 15.

In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is t
aksik [14]

The absolute value inequality is given as |(p - 0.43)I ≤ 0.019

<h3 />

<h3>How to describe the proportion using the absolute value inequality</h3>

The proportion p = 43% = 0.43

Margin of error = 1.9% = 0.019

The value of the proportion can then be said to lie between

(0.43 - 0.019) ≤ p ≤ (0.43 + 0.019)

In order to convert to the absolute inequality we would be having

-0.019 ≤ (p - 0.43) ≤ 0.019

I (p - 0.43)I ≤ 0.019
