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 answer to 3.07 3.48 4.24 using front end estimation?
It depends on what you are required to do with them - add them, multiply them, something else!

the if you will can be used many different ways the most common way i use it is if you will means you can go first
With questions like these it is often difficult to remember whether we are looking for permutations or combinations. In English we use these two terms interchangeably but in mathematics we must be more precise. The way to remember is that if the order matters, then position matters, thus position = permutation. If order does not matter then we're looking for combinations. Put simply, 123 and 321 are the same combination but different permutations. In this case we're looking for permutations (thus combination locks should really be called permutation locks).
The formula for calculating permutations is fairly simple: given 7 digits from which we must select 3, we have 7^3 = 7 x 7 x 7 = 343 permutations in total. However, in order to exclude repeated digits we must use a different formula. When we select the first digit we have 7 choices (just as we do with repetition allowed), but when we choose the next digit we only have 6 choices remaining and for the final digit we only have 5 choices remaining.
To express this more mathematically, we need to use factorials. Factorial 7 (written 7!) is 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040. This tells us there are 5040 different ways we can write all the digits from 1 to 7 without repetition. In order to calculate all the 3-digit permutations we need to stop multiplying when we reach 4. To achieve this, we use the following formula:
n! / (n-m)!
where n is the number of elements in the set and m is the number of elements we wish to select.
Thus we get:
7! / (7-3)! = 7! / 4!
If we (partially) expand this we find we have:
7 x 6 x 5 x 4! / 4!
The 4!s above and below the division will cancel each other out, so we get:
7 x 6 x 5 = 210 permutations without repetition.
If we were to fully expand this out we find we have:
(7 x 6 x 5 x 4 x 3 x 2 x 1) / (4 x 3 x 2 x 1) = 5040 / 24 = 210 permutations without repetition.
Note that if we were only interested in the number of combinations (without repetition), we divide the number of permutations by 3! For that we use the following formula instead:
n! / (m! x (n-m)!)
Thus we'd get:
7! / (3! x 4!) = (7 x 6 x 5 x 4!) / (3 x 2 x 1 x 4!)
The 4!s cancel each other out so we get:
(7 x 6 x 5) / (3 x 2 x 1) = 210 / 6 = 35 combinations without repetition.

What are the different types of variables?
The exogenous ones, which are set by an outside agent, and the endogenous ones, which occur inside a problem.
So if you look at this formula for a wave in one dimension:
y = exp(-jkx), where k = 2pi / lambda
lambda and x are exogenous while k is endogenous (j and pi are constants).
What are the numbers used in making a box and whisker plot?
The box goes from the lower quartile to the upper quartile and has the median marked across it. The whiskers stretch out, from the box, to the minimum and the maximum.

Seriously underestimated!
The correct answer is 59C5 = 59*58*57*56*55/(5*4*3*2*1) = 5,006,386
yes
How do you turn research questions into hypothesis?
the research questions is seduce to hgypotheses because some things are not practical like to see atom with naked eyes it s possible ?no
so we can hypothetical prove it by results of experiment
Because all sides are the same length, and it is a regular shape. It tessellates, because if you lay squares of the same size adjacent to each other, they will leave no gaps.
How do you find the area with diameter?
Diameter implies circle
Divide diameter by two
square it.
Multiply it by pi (3.14159...)
What does you are a procrastinator mean?
A procrastinator is a person who puts off important tasks such as home work and doing other things in place of them simply to avoid doing that task. It like prolonging, or dragging something out.
Is Mexico's death rate higher than US?
Mexico has a lower overall death rate than the US. Mexico's death rate is 4.9 persons per 1,000 while the US rate is 8.39 persons per 1,000.
Keeping in mind that life expectancy is a better measure of the conditions of life than is the death rate. The death rate can be deceptive because it is influenced by the age structure of the population. Since Mexico has a much younger population than the US its rate would be much lower for the same life expectancy.
In fact the US (about 78) has a higher life expectancy than Mexico (about 76).
