Answer:
<u>Given expression:</u>
<u>The first root is valid when:</u>
- 2x + 2 ≥ 0 ⇒ 2x ≥ - 2 ⇒ x ≥ - 1
<u>The second root is valid when:</u>
- 6 - 4x ≥ 0 ⇒ 4x ≤ 6 ⇒ x ≤ 1.5
<u>So the variable x can get values within interval:</u>
- -1 ≤ x ≤ 1.5 or
- x = [-1, 1.5]
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 =
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.
