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

What is the standard normal deviation?
The standard deviation of a normal deviation is the square root of the mean, also the square root of the variance.
What are the meaning and examples of decimal and fraction?
a decimal is a proper fraction whose denonimater is a power of ten.
a fraction is the quotient of two rational numbers.
Pl tell the a to z numaric value?
what? i am just gonna tell you pi=3.14 cause i dont get what you mean.
1 From a pack of 52 playing cards what is the probability of picking?
there are 4 1's or aces in a pack of 52 cards. Probability of picking an ace=4/52=1/13
Suppose the seven numbers are a,b,c,d,e,f and g
The arithmetic mean of all 7 is 10. So the sum of all seven ie a+b+c+d+e+f+g is 10*7 = 70.
The arithmetic mean of the fist six a to f is 11. So their sum (a+b+c+d+e+f) is 11*6 = 66.
So, g = (a+b+c+d+e+f+g) - (a+b+c+d+e+f) = 70-66 = 4
Each roll has (6 x 6) = 36 possible outcomes.
A 7 or 11 can be rolled in 8 ways:
1--6, 6--1
2--5, 5--2
3--4, 4--3
5--6, 6--5
The probability is (8/36) = 2/9
Doubles can be rolled in 12 ways:
1--1 and reverse
2--2 and reverse
3--3 and reverse
4--4 and reverse
5--5 and reverse
6--6 and reverse
The probability is (12/36) = 1/3.
The probability of both of these rolls happening consecutively is (2/9 x 1/3) = 2/27 = 7.41% (rounded)
What is 50 over 330 as a percentage?
Expressed as a percentage, 50/330 x 100 = 15.15 recurring (that is, 15.151515...) percent.
What is the probability of throwing a 3 or 6 if you role two dice at once?
In this case, you should first calculate the probability of NOT rolling either a 3 or a 6. For one die, this probability is 4/6 = 2/3. For two dice, this probability is 2/3 x 2/3 = 4/9. Therefore, the probability that you DO get a 3 or a 6 is 1 - 4/9 = 5/9.
What is the probability that a sum of 8 on the two dice will occur?
The probability of rolling (2, 6) is (1/6)2=1/36
Add 1/36 for all the other ways to roll 8 - (3,5),(4,4),(5,3),(6,2)
Total probability is 5/36
What are the structures of a stem?
On a stem, there are nodes, which is the place where the leaf attaches to the stem. There are also leaf scars, which are places where old leaves used to be attached. There are the internodes, which are the areas between the nodes. The lateral buds are located at the nodes, and they are underdeveloped tissues that turn into the branches and leaves that we see now. Finally, there are terminal buds, which are the reason trees are able to grow upwards. Once the bud develops, it leaves a bud scale scar, which is symbolized by rings around the tree branch.
What is a No Cor elation graph?
There are three types of correlation: positive, negative, and none (no correlation).
- Positive Correlation: as one variable increases so does the other. Height and shoe size are an example; as one's height increases so does the shoe size.
- Negative Correlation: as one variable increases, the other decreases. Time spent studying and time spent on video games are negatively correlated; as the your time studying increases, time spent on video games decreases.
- No Correlation: there is no apparent relationship between the variables. Video game scores and shoe size appear to have no correlation; as one increases, the other has no effect. A No Correlation graph would show this.
What is the least common multiple of 14 and 31?
the least common multiple of these two values is 434 (their product).
CANOY a family last name & not canopy is what I am wanting to know.
the equal nukber would be 1000987654 but if you put it that way you will lose the stautus chart and it will mess you up i am a math teacher for 12 grade i know my stuff
