What is the dimension of a skew symmetric matrix of order 3?
In a skew symmetric matrix of nxn we have n(n-1)/2 arbitrary elements. Number of arbitrary element is equal to the dimension. For proof, use the standard basis.Thus, the answer is 3x2/2=3 .
How do one determine when a data is normally distributed?
Use the Kolmogorov Smirnoff goodness-of-fit test. A normal distribution is a bell shaped curve, which is nearly symmetrica. It looks like an upside down bell. It can be squished low (platykurtic) or pulled high and skinny (leptokurtic) but it is still bell shaped and symmetrical. A mathematical test is to use the pearson's skew. If the pearson's skew is between 0 and 0.49, then the data is a non-problematic or normally distributed. If it is greater than 0.50, then it is not a normal distribution so one cannot treat it as such. The pearson's skew equation is skew p= (3 (mean - median)) / (SD(x) SD(y))
How would you use chaos in a sentence?
After the hurricane I saw a lot of chaos.
What size miter saw do you need?
I like to use a 12 inch dewalt miter saw. But really it depends on what you will be trimming to figure out exactly what size you will need. Mike
Saw the equation and explain the steps you use to saw 744 31?
The answer to 744 times 31 equals 23,064. To solve this all you have to do is add 744 31 times.
