A polygon is regular when all angles are equal and all sides are equal (otherwise it is "irregular"). This is a regular pentagon (a 5-sided polygon)
Answer:
It would be the first graph because |x| >5 is solved in two cases
The first case you keep everything the same, just get rid of the absolute value bars
x>5
The second case, you need to switch the sign and make the 5 negative
x<-5
When graphing you want to put an open circle on -5, and 5 because when it is < or > you have an open circle,
You then point the arrows going which ever way your sign is going, this is why the -5 is going to the left because the < sign is pointing left, and same with the 5, the arrow is going right because the > sign is pointing right
Hope this helps ;)

Answer:
No
Step-by-step explanation:
<u>Explanation</u>:-
- The graph of the normal distribution y = f(x) in the x y- plane is known as normal curve.The curve is bell shaped and symmetrical about the line x = μ
So The first statement is not true because symmetrical about the line x = μ not 'm'
- Area under normal curve represents the total population
so the total area under the curve is 100 or one so The second statement is true
- The normal distribution for mean is zero and standard deviation is one is known as standard normal distribution.
- 95 percentage within two standard deviations
- 99.7 percentage of the data are within three standard deviations of the mean.
- 68 percentage of the data are within one standard deviation
All above points are true so In given data the third statement is not true
95 percentage within two standard deviations not one
- The fourth statement is false because 68 percentage of the data are within one standard deviation not 34 percentage.
- All data sets are normally distributed its depend on given data
