How do you apply your knowledge about correlation and causation to real life?
1 answer:
Answer:
Both positive correlations and negative correlations (when one variable increases as the other decreases) can be found everywhere you look. For example, when you spend more time in sunlight, your chances of getting a sunburn also go up. More examples of positive correlations include:
The more time you spend running on a treadmill, the more calories you will burn.
The longer your hair grows, the more shampoo you will need.
Step-by-step explanation:
21,23,23,27,29,29,33,33,34,36,37,38,39,40,41,43,44,45,56,56
The minimum is the lowest number in the data set. Since it is listed from smallest to largest, we know that the minimum is 21. The median is the middle number. Cancel out 9 numbers from each side and add the two numbers 36+37 then divide the answer by 2 to get the median.Therefore, the median is 36.5
The maximum is the highest number in the data set; it is 56.

The row echelon form of the matrix is presented as follows;
The row echelon form of a matrix has the rows consisting entirely of zeros at the bottom, and the first entry of a row that is not entirely zero is a one.
The given matrix is presented as follows;
The conditions of a matrix in the row echelon form are as follows;
- There are row having nonzero entries above the zero rows.
- The first nonzero entry in a nonzero row is a one.
- The location of the leading one in a nonzero row is to the left of the leading one in the next lower rows.
Dividing Row 1 by -3 gives:
Multiplying Row 1 by 2 and subtracting the result from Row 2 gives;
Subtracting Row 1 from Row 3 gives;
Adding Row 2 to Row 3 gives;
Dividing Row 2 by -2, and Row 3 by 18 gives;
