First of all, you need to come to an understanding of what you mean by "compare that score to the population." Often, that will mean determining the percentile rank of the score.
To determine the percentile rank of a raw score, you first nomalize it by determining the number of standard deviations it lies from the mean. That is, you subtract the population mean and divide that difference by the population standard deviation. Now, you have what is referred to as a "z-score".
Using a table of standard normal probability functions (or an equivalent calculator or app), you look up the cumulative distribution value corresponding to the z-score you have. This number between 0 and 1 (0% and 100%) will be the percentile rank of the score, the fraction of the population that has raw scores below the raw score you started with.

Answer:
13 ft
Step-by-step explanation:
c^2 = a^2 + b^2
C^2 = 5^2 + 12^2
C^2 = 25 + 144
c^2 = 169
c = 13 ft
One thousand = 1000
two hundred = 200
eighty = 80
six = 6
For word form, change the standard form into words:
Word form: One thousand, two hundred, and eighty-six
For standard form, change the words into numbers
Standard form: 1,286
For expanded form, expand the number so that each value number is separated
Expanded form: 1000 + 200 + 80 + 6
hope this helps
