The density curve must satisfy two important conditions.
These two conditions are:
1- The total area under the density curve MUST BE equal to 1.
(Area total = 1)
2- Every point that is on the curve must have a vertical height that is equal to or greater than zero
(vertical height for each point ≥ zero)<span>

Answer:
11.1% change
Step-by-step explanation:
first find their differences
80-72 =8
secondly
set up a fraction to find the percentage change
because percentage deals with fractions
8/72 *100 ( because percentage is over 100)
lastly
you simply
0.111111*100
=11.11%. ans
Answer:

Step-by-step explanation:
Bar graph display directly the varibales which are the rate and ratio of the numbers to visualize and display the results, these contrasting the different outcomes. On the contrary, histogram is used in grouped frequency parameters. Moreover, as little as the given five parameters or data set this will be ineffective and will result to a bar graph only and basically, the suited option is the aforementioned vertical graph to display the numbers. To expound on the definition of histogram it is used when the frequency is grouped. For example the data set of 1-5, 6-10, 11-15 and 16-20 this now can be used and applied to illustrate histogram because of the number and quantity of the given data.<span>
