Think these are the answers to the first few hope it helps
Greetings from Brasil...
Let's apply the given formula:
A = (1/2)·B·H
The base of this polygon (in this case, the triangle) is B
B = X² - 2X + 6
The height of this polygon is H and is H
H = X + 4
Applying these values (B and H) in the given formula.....
A = (1/2)·B·H
A = (1/2)·(X² - 2X + 6)·(X + 4)
A = (1/2)·(X³ + 2X² - 2X + 24)
A = (X³/2) + X² - X + 12
OR
A = (X³ + 2X² - 2X + 24)/2
So 20x68 is 1360 so 3,619 -1,360 is 2,259 so 2,259 more people will be able to fit inside of the auditorium-hope this helped you
For skewed data displays, the median is often a better estimate of the center of distribution than the mean because the former is unaffected by large numbers.
<h3>What is mean?</h3>
Mean refers to the average of set of two or more numbers.
Mean of a set having 'n' numbers = 
<h3>What is median?</h3>
Median refers to the middle-most value of a list of numbers, arranged either in ascending or descending order.
Median = 
Now,
- Since it takes the average of all the values in the data set, the mean is the most widely used measure of central tendency.
- Because it is unaffected by exceptionally big numbers, the median performs better than the mean when analyzing data from skewed distributions.
Hence, For skewed data displays, the median is often a better estimate of the center of distribution than the mean.
