The data points are a little closer for a weak correlation, and you can see that there is some sort of relationship between these factors.
Data points for a strong correlation are in close proximity to one another, making it possible to build a line by imitating their pattern.
A statistic called correlation gauges how much two variables change in connection to one another.
Correlation and diversification, the idea that certain types of risk can be reduced by investing in assets that are not connected, are closely related concepts.
Correlation cannot determine whether x causes y or vice versa, or whether a third component is responsible for the association.
A scatter plot may make it easier to spot correlation, particularly when the variables have a non-linear but nevertheless significant association.

Answer:
obtuse triangle
Step-by-step explanation:
it is obtuse because it needs to have all 3 sides to be acute to be an acute angle and it doesn't have any 90° angles so it has to be obtuse. Also because to be an obtuse it has to have 2 acute angles and 1 obtuse angle. Hope this helps!!
In a triangle, the three interior angles always add to 180°
x + 3x + 5x = 180
9x = 180
x = 180/9
x = 20
<span>the smallest angle = x = 20</span>°
Solution :
Let the distance of the stick from one break be X
And let us assume that 
.
Here, l = length of stick
Therefore, 
We know that, 
, so by definition we get
The cumulative distribution function for R is
When it starts at zero, then r =0. It ends at one when the r has a maximum
value of one.
The probability density function is given by
Now integrating, we find E(R) and 
gives :
Therefore, Var(R)=
