By using a scatter plot we can get the relationship of two variables or correlation.
There will be two types of correlation.
If the data of the plot show a positive slope of the estimated line then it will be a positive correlation.
Now a correlation value lie between 0 to 1 if it is very close to 0 like 0.1 , 0.2 then we can say the correlation is weak psitively correlated. and if it will be close to 1 like 0.8 or 0.9 then the correlation will be strong.
Similarly if slope of the estimated line will be negative then it will be a negative correlation.
From the above scatter plot notice that it has a negative slope and we can draw a fair estimate line on this scatter plot. So, there is strong negative correlation.
Hence the correct choice is -0.8.

Answer:
AD=5.82 units
Step-by-step explanation:
tan 31=3/BD
0.6009=3/BD
BD=5
AD^2=3^2 + 5^2
AD^2=9+25=34
AD=5.82
The answer to that question is C
