Completing the squares tells us exactly what square root we will need to calculate our answer.
Using the formula below you can find these answers:

Does this make sense?
The probability is 0.9671.
The z-score for this is given by
z = (x - μ)/(σ/√n)
z = (38000-37500)/(1561/(√33)) = 1.84.
Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of, less than, this is 0.9671.
The answer to solve these problems is that the full circle is 360 degrees, the way to find the answer is to have to equal sides that equal 360 degrees. That means one half of 360 degrees is 180 degrees. Hope this helps.

The above numeral can be split as follows:

X means 10 and L means 50.
But because X (10) which is smaller comes before L (50), XL is executed as:


In Roman numerals;

Substitute 40 for XL and 4 for IV.


Hence;
