A correlation value of 0.65 that indicates a moderate positive linear relationship can be used to describe relationship between weight and age of animals.
Step-by-step explanation:
We are given the following information in the question:
Correlation:
Correlation is a technique that help us to find or define a relationship between two variables.
It is a measure of linear relationship between two quantities.
A positive correlation means that an increase in one quantity leads to an increase in another quantity
A negative correlation means with increase in one quantity the other quantity decreases.
+1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.
Values between 0 and 0.3 tells about a weak positive linear relationship, values between 0.3 and 0.7 shows a moderate positive correlation and a correlation of 0.7 and 1.0 states a strong positive linear relationship.
Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.
Since, the weight of an animal increases with age a correlation value of 0.65 that indicates a moderate positive linear relationship can be used.
it is 12 cm because look at the sides put the triangles next too eachother it make a rectangle and do the standard parallelagram equation base times hight it is 12
