Why you do numerical analysis on Computer?
In most practical situations the calculations required to do numerical analysis are so lengthy and tedious that they are too expensive to be performed by people nowadays, especially since they generally involve simple arithmetic rather than anything requiring human intelligence.
What is a dummy variable in Operations research?
There are various forms.
In linear programming, a dummy variable may be used to convert an inequality into an equation. For example x < 10 can be written as x + u = 10 where u > 0. In this case, it is also called a slack variable.
Dummy variables are used in regression to indicate the presence or absence of a factor, or for binary variables. For example, male/female could be coded numerically as 0/1 where, because the question is binary, the exact coding does not matter.
How do you write a ratio as a fraction in it's simplest form?
If you want to write a:b as a fraction, make a the numerator and b the denominator. You get a/b.
What are some special meanings of the number 45?
The number 45 does not have any meanings that are special to the extent that they cannot apply to other numbers.
3.775/1 is 3775/1000 which is 755/200 which is 151/40.
What does an asterisk mean in a mathematical equation?
The asterisk in a mathematical equation, usually in the context of a computer expression, means to multiply.
What is the difference between declarative and executable staments?
A declarative statement introduces an identifier, and indicates its type, sometimes implicitly. It may also assign a value to the space indicated by the identifier which may or may not be mutable within the program. Declaratives are not considered executables.
An executable statement can be any sort of statement requiring action, including assignment of a value to the space indicated by an identifier, calling a function or procedure, reading or writing, pausing or stopping execution, waiting for another process, etc.
What are the applications of numerical method?
Numerical methods are used to find solutions to problems when purely analytical methods fail.
What is 3.03 to 3 decimal places?
three decimal places means three numbers after the decimal place, so 3.030
58 inches is the same as 4' 10''. That is quite short, as the average human height is around 5'7".
How do you write three different improper fractions that equal 4 and 2 thirds?
- First change 42/3 (a mixed fraction) into an improper fraction. Do this by multiplying the 3 times the 4, and add the 2. The answer is 14/3.
- There is an infinite number of improper fractions that reduce down to 14/3. Just multiply the top and the bottom (numerator and denominator) by the same number and you will have several different equivalent fractions.

- 28/6 ,
- 42/9,
- 56/12,
- 266/57
- 14/3
What is the velocity for a baseball ball rolling on grass?
It depends on the initial velocity, and it also depends on time, because the friction of the grass will slow the baseball down.

What is the formula for the how many squares do you see puzzles?
Sum of N2 for N=1 to X, and X is the number of squares across the top or side on the large square.
How many ways the word engineering can be rearranged?
