Answer:
$36.00 markup
Step-by-step explanation:
$72 x 50% (0.50) = $36.00
Answer:

Step-by-step explanation:
The question we have at hand is, in other words,
- where we have to solve for the value of 
If we have to isolate
here, then we would have to take the inverse of the following matrix ...
... so that it should be as follows ... 
Therefore, we can conclude that the equation as to solve for "
" will be the following,
- First find the 2 x 2 matrix inverse of the first portion,
=
=
=
At this point we have to multiply the rows of the first matrix by the rows of the second matrix,
,
- Simplifying this, we should get ...
... which is our solution.
528= 8x+240
288=8x
x=36 hours
<span>The correlation coefficient is a value that signifies correlation and dependence between two or more values. </span>The following statements are true:
- The correlation coefficient is a unitless number and must always lie between –1.0 and +1.0, inclusive.
- The correlation coefficient, r, gives us information about the strength and direction of a linear relationship between any two variables.
<span>- The larger r is in absolute value, the stronger the relationship is between the two variables.
