How do i solve absolute value equalities?
4| n+8 | = 56

Step-by-step explanation:

I believe you do, 4 times each number in the absolute value symbol. 4 times n, 4 times positive 8.  4n+32=56

You minus 32 on both sides and you get 24. Then you take 24 and divide it by 4, and there is your answer 6.

You can check it by plugging 6 into the equation.

Step-by-step explanation:

Correlation coefficient is the measure of linear association between two variables.  It is the ratio of cov of two variables divided by product of std deviation of each variable.  If outliers are present std deviation would be more and hence affects the correlation value very much. The correlation coefficient ranges between -1 and 1.  If negative we say negative association and vice versa.

Hence the correct true statements are

A correlation coefficient of zero means that no relationship exists between the two variables.

The sign of  corr.coeff. describes the direction of the association between two variables

When the data points in a scatter plot are randomly scattered, the correlation between the two variables is weak.

The value of corr.coeff ranges from negative one to positive one.
