Please help. I don’t understand how to do this
Rasek [7]

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

For skewed data displays, the median is often a better esitmate of the center of distribution than the mean, but
bazaltina [42]

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 = \frac{Sum Of 'n' Numbers}{n}

<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 = \left \{ {{\frac{n}{2}^{th}  term, if n = even } \atop( (\frac{n-1}{2}+\frac{n+1}{2})/2)^{th} term, if n = odd   }} \right.

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.
