Statistics
Statistics deals with collecting, organizing, and interpreting numerical data. An important aspect of statistics is the analysis of population characteristics inferred from sampling.

There are 6 kids in my family and they r 13 12 11 9 7 and 7 could we b a reality show and How?
um no one would wana watch that show i would rather watch a program on the tree octopus
What is 28 over 63 as a percentage?
Expressed as a percentage, 28/63 x 100 = 44.4 recurring (that is, 44.4444..) percent.
Assuming as the die is rolled, and its a 6-sided die (1, 2, 3, 4, 5, & 6), each number has a 1/6 probability of being rolled. The probability of any number being rolled is 1/6 and the probability of not rolling that number is 5/6. Something that has only 2 outcomes, such as boy & girl or heads & tails, will have the 50 50 probability.

10cm is 100,000um. 100,000/20 is 5000 magnification
How do you find out the total current in PCB?
a: usually taking the high side of the buss or the return and measuring the current
What is the probability of getting heads one-half N times when flipping a coin N times?
If N is odd, the probability is 0.
If N is even, suppose N=2M
then the probability is 2MCM*(1/2)2M which approaches 0 as N (or M) increases.
For N = 10, Prob = 0.1762
For N = 20, Prob = 0.1254
For N = 30, Prob = 0.1026
For N = 80, Prob = 0.0630
Is 20 decimeters greater than 2 meters?
Not really. It takes 20 decimeters to equal 2 meters. So therefore, they are the same length.
What is the rage of 15 18 19 23 25?
Assuming that those are Y values, and by 'rage' you meant 'range', then the range would be lowest value to highest value, or 15 to 25
How many times in an average age of 50 years would my name be called my lifetime?
Probably never, unless your name happened to be "MY LIFE TIME".

September 2013, Friday the 13th. Oh, and download the free app "app trailers" an I device(like an iPod or something) enter "giftcard9" as a promo code then you will be making free money. Seriously try it. I'm not a robot.
How many triangles are on a pyramid?
A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices and 2n edges, where n ≥ 3.
How do you make -2 using all four operations and only the numbers -1 -2 -3 -5 and -7?
[(-2) + (-1)]/(-3) * [(-7) - (-5)]
What is the differences between dependent variables and controlled variables in an experiment?
Controlled variables are things that may effect the outcome of an experiment, like temperature are pressure or the amount of some substance used.
Dependent variables are those which change due to the conditions mentioned above.
These might be speed of the reaction, or the quantity of some product.
What does mean median in math?
The term median refers to an average value indicated by the middle number or numbers in a series. It can be different from the "mean", which is the average value found by adding the numbers and dividing.
Where there is an odd number of values, the median is the central (middle) value.
For example, in the set [ 1, 2, 7, 50, 100 ] the median value is 7. There will be as many values less than the median as there are greater than the median. (if you have duplicate values, more than one may be equal to the median)
Where there is an even number of values, the median is the mean (average) of the two central values. For example, in the set [ 1, 2, 7, 9, 50, 100 ], there are two central values, 7 and 9. The median would be 8, and again there will be as many values less than the median as there are greater than the median.
To find the median : put your numbers in order by their value, and count the number of values. Divide the number of values by two to locate the center value or values. Where the number of values is even, add and average the two in the middle.
Example : values [ 27, 18, 3, 99, 55, 1, 16 ]
Ordered set : [ 1, 3, 16, 18, 27, 55, 99 ]
Median : 18

The above may not have been serious, but it is correct - there are two variables, h and i. The following is also a correct answer:
3h2 -5i
How do you determine the units of a problem using dimensional analysis?
I suggest you search for some examples to get the general idea. Basically, you convert all units to generic descriptions such as [length], [time], [current], etc.; then you combine them. If you add a length to another length, you get a length again, so:
[length] + [length] = [length]
Similarly,
[length] - [length] = [length]
Please note that:
1) This is different from regular addition or subtraction.
2) You can't add or subtract different types of units. For example, if in a formula you are supposed to add a speed and an acceleration, you get:
speed + acceleration
= [length] / [time] + [length] / [time]2
... which can't be added. If you get something like this, something is wrong with this formula. Such formulae might be used as "rule-of thumb" formulae, and might sometimes give good approximations - but they are not dimensionally correct.
On the other hand, if you multiply or divide units in a calculation, you get the regular product or quotient, for example:
[length] times [length] = [length] squared.
Give mathematical experssion for pascal triangle?
See link at bottom. Pascal's triangle begins with a 1 at the top. This is row 0. The first row of Pascal's triangle 1,1 corresponding to n = 1 and i = 1 and 2. The second row of Pascal's triangle is 1, 2, 1, corresponding to n = 2 and i = 1, 2, 3 If we have (x+y)^2, we have (1) x^2 + (2)xy + (1) y^2 so Pascal's triangle gives the constants in front of the variables. Also, ai = n!/[i! x (n-i)!] Example, 5th row third element is 10, which is calculated as 5!/[3! x 2!] = 5 x 4/2 = 10. http://en.wikipedia.org/wiki/Pascal's_triangle
'Latiskia' is Lithuanian for the phenomenon where upon a child defecates inside someone elses school bag and then drives the bag into the anus of a goat. After approximately 37 hours the faeces becomes rancid and can be smeared on my nan for a pleasant breakfast. This ritual usually takes place on the first weekend of the equinox when the great goat constellation is high to the south and the banana frog spawns in the drinking troughs.
