Management information system requires tables, Tables are used only if a person is trying to analyse data and understand its business by summarizing.It is the 1st step of data analysis collecting data. Scatter plot is used when there is a question of association of two or three variable.

Step-by-step explanation:

Table is the matrix to stack up the data in there respective columns.
It is the most important setup to analysis.
It's better used collecting data for any projects or business.
Tables are even used for Bio statistics and Analytics.
Databases uses tables for one query table to another query table.
Scatter plot is dotted plot which analyse two variables.
Example if a project is eating chocolates in gram in x axis.
Gaining weight in y axis two variables are used to predict and outcome.
If a person eats this amount of chocolate it will gain this wait.
Association rules, contingency statistics and rest.

IF NR = 8 ft, what is the length of arc NMP. Round to the nearest tenth.

Pavlova-9 [17]

Check the picture below.

since chords NQ and MP cross the center of the circle at R, that means that those two chords are diametrical chords and the angles made by both are vertical angles and thus twin angles, namely both are 18° as you see in the picture, so the angle NMP in magenta is really 162° + 18° + 18° = 198°, and we know the radius NR is 8.

$\textit{arc's length}\\\\ s=\cfrac{r\pi \theta }{180}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ r=8\\ \theta =198 \end{cases}\implies s=\cfrac{(8)\pi (198)}{180}\implies s\approx 27.6$
