Y=mx + b
10x.5y.10=30
10x.5y=30-10
10x.5y=20
5y= -10x + 20
5/5 = -10/5(x) + 20/5
Y= -2x +4
- The distribution is skewed left.
- The median is an accurate measure of center.
- The interquartile range is an accurate measure of spread.
<h3>How to find the Distribution of data?</h3>
Probability plots might be the best way to determine whether your data follow a particular distribution. If your data follow the straight line on the graph, the distribution fits your data. This process is simple to do visually. Informally, this process is called the “fat pencil” test.
For skewed distributions, it is quite common to have one tail of the distribution considerably longer or drawn out relative to the other tail.
As, it is known that, when the distribution of data is left-skewed, the mean is less than median.
- In any research of distribution, the distribution is described by its shape. If there are more higher values than lower values, the distribution is skewed left.
- The distribution can be described by its center. If the distribution is skewed left or right, the median is an accurate measure of center.
- The distribution can be described by its spread. If the data set does not have an outlier, the interquartile range is an accurate measure of spread.

#SPJ1
the answer to the question is 72.500
We first need to find the gradient of the line
From the graph, we see the graph intercepts y-axis at -1
Hence, the equation of the line is
Given
The graph of the infant mortality rate and life expectancy is given in the scatter form.
Explanation
To determine the relation between the life expectancy and infant mortality rate ,
use the given graph.
From the graph given, it is clear that as the infant mortality rate increases then the life expectancy decreases.
Therefore, the countries with high mortality rates tended to have shorter life expectancies.
Answer
Hence the correct option is B.
