In automobile mileage and gasoline-consumption testing, 13 automobiles were road tested for 300 miles in both city
and highway driving conditions. The following data were recorded for miles-per-gallon performance.
City: 16.2 16.7 15.9 14.4 13.2 15.3 16.8
ANSWER: The curves y = x^3 and y = 30 - x intersect at x = 3
so find the centroids for x^3 from 0 to 3 and for 30 - x from 3 to 30 ( 30 =
the x and y coordinates of the first area are
xc1 =(x*x^3dx from 0 to 3) / (x^3)dx from 0 to 3
Database redesign is necessary for two reasons.
First, redesign is necessary both to fix mistakes made during the initial database design. Second, redesign is necessary to adapt the database to changes in system requirements. Such changes are common beca
An empty cell means that the current system lacks the particular

We express complexity using big-O notation. For a problem of size
a constant-time method is "order 1": O(1)
a linear-time method is "order N": O(N)
a quadratic-time method is "order N squared": O(N2)
Note that the big-O expressions do
The reason why green computing should be part of any organizations social responsibility posture is because it
would help reduce our carbon footprint on the world.
There are actions that these IT companies can take in order to reduce their carbon footpr
Consider the equation x 1 x 2 5 x 1 :
Divide both side of equation by x 1 and solve for x as
x 1 x 2
x 1 x 2
5 x 1
5 x 1
Therefore, the solution is x 3 .

The method that is implemented to get to the optimal solution is known as Linear Programming.
This is done by study of analysis of the program and forms the result in terms of coefficient optimization.

In numerical analysis, a branch of mathematics, there are several square root algorithms or methods of computing the principal square root of a nonnegative real number.
For the square roots of a negative or complex number Perhaps the first algorithm used
The Central Limit Theorem consists of three statements:
 The mean of the sampling distribution of means is equal to the mean of the population from which the samples were drawn.
 The variance of the sampling distribution of means is equal to the
