Which graphical display is best used to organize numerical data in ascending order?

scatter plot
line graph
box-and-whisker plot
stem-and-leaf plot

line graph

Step-by-step explanation:

Line graphs easily help the visual learner to interpret data and understand peaks and decreases in certain levels. It connects data points and allows people to see what is actually going on.

line graph

Step-by-step explanation:

The explanations of each plot are:

Scatter plot

It is used to see the correlation between two variables. The correlation can be positive (increases), negative (decreases) or zero (no correlation at all). This plot can be used to draw a trend line to study the correlation between variables using an equation, generally a line and which prosses is call line regression.

Line graph

Is like the scatter plot but instead of leaving the data or points without connection the line graph connects the points, representing the data, with a line, so to easily show a tendency between variables, which generally tends to increase.

This plot is an easy way to show a tendency, but the scatter plot can give more statistical information about a correlation between variables.

box-and-whisker plot

Shows the median and the quartiles of the data, i.e. shows a interval in which the recollected data can be found and its frequency of repetition.

stem-and-leaf plot

Allows to simultaneously see the frequency distribution of the variable and its graphic representation and its constructed by separating, in each data, the last digit of the right (the leaf) to the remaining digits (the Stem).  

So, to easily show numerical data in ascending order it can be used the line graph, but it can be used de scatter plot to give deeper statistical information too.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
