To find the fraction of floats not represented by sports teams, subtract the number of sports team floats from the total number of floats and place this over the total number of floats. Then simplify the fraction if possible.
This problem falls in the category of fraction concepts and percentage calculations which are parts of Mathematics. In order to answer your question about the fraction of floats not represented by sports teams, I require two critical pieces of information:
If we subtract the number of sports team floats from the total, we will get the number of non-sports floats. We then put this number over the total number of floats to make our fraction. Afterwards, we simplify the fraction if necessary

Using it's concept, it is found that the variance of the given data-set is of 17.14.
It is the sum of the differences squared betweene each observation and the mean, divided by the number of values.
The mean of the given data-set is given by:
M = (3 + 4 + 5 + 7 + 10 + 12 + 15)/7 = 8
Hence, the variance is given by:
V = [(3-8)² + (4-8)² + (5-8)² + (7-8)²+ (10-8)² + (12-8)² + (15-8)²]/7 = 17.14.

Answer:
(3 + 4 + 5 + 7 + 10 + 12 + 15)/7 = 8
(3^2 + 4^2 + 5^2 + 7^2 + 10^2 + 12^2 + 15^2)/7 - 8^2 = 17.14285714
Answer:
The answer is 0.2
Step-by-step example
First multiply two and sixty which equals 120,then multiply ten and sixty which equals six hundred then divide it by eachother which equals zero point two.
