mu = 1100 = population mean
sigma = 275 = population standard deviation
x = 1400 = raw score
z = z score
z = (x-mu)/sigma
z = (1400-1100)/(275)
z = 300/275
z = 1.0909090909091 approximately
z = 1.09
Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).
The positive z score is due to Paula's raw score being above the mean.
Thats like geometry
and are you good in this suject?
I am not sure, but I think you are talking about the least square method
Another word that has horizontal line symmetry is "book" and it is possible to form words with vertical line symmetry.
<h3>What is horizontal line symmetry in letters?</h3>
This implies that by dividing the letter in half using a horizontal line both sides would be the same. Lettters with horizontal line symmetry include:
<h3>What are some words with these symmetry?</h3>
<h3>Are words with vertical line symmetry possible?</h3>
Yes, they are because there are many letters that have this symmetry such as V, T, A, O, M, I, H. For example you can create the words:
