Answer:
Option 2nd is correct.
Step-by-step explanation:
In right angle triangle:
Pythagoras theorem follows which is:
Here, c= hypotenuse b is one side and a is the other side.
Therefore, according to Pythagoras theorem Option 1,3 and 4 are discarded.
Option 2nd is correct because KL=EF and triangle KLM and EFG follows Pythagoras theorem which makes them a right angle triangle.

The correlation Coefficient, R shows the degree or level of relationship between the dependent and independent variable. A positive R value denotes a positive correlation while a negative R value denotes a negative relationship. R values should range between - 1 to +1 with values close to 1 and - 1 depicting strength while value of zero means no relationship exist.
Hence, R value of -0.90 depicts a strong negative relationship. Hence, higher speed are related to lower miles per gallon and vice versa.
