What are possible answers? I’d love to help!!
<span>If 6 people meet and shake hand with each other. First person
will shake hand with other 5, second person had already shaked hand with 1st person and shake hand with other 4, and
so on…</span>
So, the total no. of handshakes=
5+4+3+2+1=15 shakes
The other way to calculate
this is by the formula n (n+1)/2
Where n is the no. of shake
hands by very first person and that is 5.
So, the total no. of handshakes=5(5+1)/2
= 5(6)/2
=30/2
=15 shakes
One buyer, many sellers and no close substitutes
usually this won't have an exact example to match all the requirement
so, try get those small company as the example of your answer
<span>A trend extrapolation is detecting faulty underlying assumptions before forecasting errors can occur. This is to allow forecasters to place a trend that is evident over time, and then calculate it forward base on the calculated data relating rates of change. An example is detecting the climate of the day. Forecasting it is not easy since analysts have to extrapolate the past data to predict the future event. </span>
