Correlation coefficients range from to a correlation coefficient suggest the and of the relationship between variables. a correlation of indicates a perfect positive relationship; indicates a perfect negative relationship; and indicates that there is no linear correlation between the variables.

Correlation coefficients range from _-1__ to _+1__. A correlation coefficient suggest the _strength__ and _direction__ of the relationship between variables. A correlation of _+1__ indicates a perfect positive relationship; _-1__ indicates a perfect negative relationship; and _0__ indicates that there is no linear correlation between the variables.

Step-by-step explanation:

Correlation Coefficient(r) shows the direction and strength of relationship between two variables.  

The formula used to calculate correlation is:

where, Cov(x,y) = Covariance of x and y

  = mean of x

= mean of y

= standard deviation of x

  = standard deviation of y

and,  E = Expectation.

The correlation coefficient lies between -1 to +1.  

As the increase in the value of one variable also increases the value of other variables is called positive correlation. Also, the value of positive correlation lies between 0 to 1.

And decrease in the value of one variable, increases the value of other variables is called negative correlation. Also, the value of negative correlation lies between -1 to 0.

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
