Which of the following are true statements?
Alika [10]

Answer:

I and II.

Step-by-step explanation:

Dot plots are charts that<em> represent data points on a simple scale using filled circles</em>. Stemplots allow <em>plotting data by dividing it into stems (largest digit) and leaves (smallest digits)</em>. Both dot plots and stemplots are like histograms since they allow to compare data relating to only one variable, and are used for continuous, quantitive data, highlighting gaps, clusters, and outliers.    

Histograms <em>use bars to represents amounts, with no space between the bars and </em>the height of the bars is proportional to the frequency or relative frequency of the represented amount. <u>We refer to the relative frequency of a case when this frequency is divided by the sum of all frequencies of the cases</u>. The proportionality between the height of the bar and the frequency is right when the width (interval) of the bar is the same for everyone, on the contrary, the area of the bar would be proportional to the frequency of cases.      

Therefore, of all the above, the correct statements are I and II. Statement III is incorrect because relative <em>heights </em>are proportional to relative <em>frequencies</em>.        

 

I hope it helps you!

An unknown number w is 30 more than an unknown number p. The number w is also p less than 5
AleksandrR [38]
The problem statement gives rise to two equations.
  w = 30 + p . . . . . w is 30 more than p
  w = 5 - p . . . . . .. w is p less than 5

Add these two equations to get
  2w = 35
  w = 35/2 = 17.5
  p = 5 - w = -12.5

The unknown number w is 17.5.
The unknown number p is -12.5.
