In the case of a book sitting on a desk, the force of gravity is shown as an arrow pointing down from the bottom edge of the box. The force of the desk pushing upward on the book, called the normal force, is shown by an arrow pointing up from the top edge of the box. For an object in motion, the applied force is shown as an arrow pointing in the direction of motion, and friction is shown as an arrow pointing in the opposite direction from the back edge of the box. Arrows of different lengths are used to indicate the relative magnitude of the various forces.
How do you calculate FTE?

FTE is considered to be eight hours in a day, multiplied by five days a week. This number is then multiplied by 52 weeks a year, and the calculation is 2,080 hours that an employee works in a year. If the total labor hours for a company within a year was 18,245, that would be divided by 2,080. In this case, FTE would be 8.77 FTEs.FTE can also be calculated by using the labor hours in one month, divided by 173.33. The figure of 173.33 is representative of 2,080 divided by 12. Labor hours can also be calculated on a daily basis for FTE calculations. This number would be divided by 8. For example..

When calculating the area of a room, begin with the shapes that compose it. Note these and reconstruct the room as the sum of these shapes, such as a large rectangle with an attached square and small triangle. Measure the height and width of each of these and multiply the two figures. This will provide a set of individual square meterage figures that you can then add together to find the entire room's sum.
How do you use a random number generator?

While the name implies that the generator provides entirely random numbers, this is not true, because it is impossible for a computer to generate anything truly at random. A random number generator uses what is called a seed. A seed is an arbitrary input taken from within the system, usually from the clock of the computer running the generator. This appears to be random, as the clock cannot be easily altered or controlled by the user. The arbitrary data taken from the clock is then interpreted back into a number within the specified range. Every time the random number generator is initiated, i..

The rules of baseball underwent a thorough revision in 1857 that shaped the parameters of the modern game including having nine innings in a game, nine players on a team and ninety feet between bases. There is one pitcher, a player to cover every base, a catcher, a shortstop to cover the distance between the bases and three outfielders.\nThe myth of the cat with nine lives comes from a ritual in Medieval Europe of throwing cats from tall towers. One legend is told of Baldwin III, Count of Ypres, who dropped many cats from a tall tower in the town, most of which survived.\nThe U.S. Supreme Cour..

Polygons are two-dimensional shapes comprised of straight lines that are connected to each other. The name "polygon" comes from the Greek language and means "many angles." Polygons that have equal angles and sides are called "regular polygons." Those that do not have equal angles and sides are irregular. Examples of common polygons include the triangle, which has three sides; pentagon, which has five sides; hexagon, which has six sides; and octagon, which has eight sides. Polygons can have an infinite number of sides; for example, a megagon is a polygon with 1,000,000 sides.Quadrilaterals have..

Identify and separate the factorsSeparate the monomial into its individual constituents. In the case of the monomial, 12x^3y^2, the individual factors are 12, x^3 and y^2. X^3 and y^2 are both variables, and 12 is a constant.Break down the constantBreak down the constant into its prime factors. These are factors that cannot be broken down into real integers any further. Twelve breaks down into its factors of 3 and 4. Three is a prime number, and its only other factor is 1. Four factors out to 2 and 2. Two is a prime number. Therefore, the prime factorization of 12 is 3 * 2 * 2.Look at the degr..
Why is sampling important?

Fields of science such as biology, sociology and psychology often study questions about large populations. These could be human populations or animal populations. It is impractical, and usually impossible, to attempt to study or survey every member of a population; studying a sample of that population is a more attainable goal. Simple random sampling is a common approach to sampling and allows all individuals and subsets to have equal weight and probability of being selected. The benefit of simple random sampling is that a truly random sample eliminates all bias. The problems of simple random ..

There are four basic steps to statistical analysis. First, identify the problem by asking a question answerable through statistical data. Next, implement a data collection process, such as interviews, observations or experimentation. Organize the data collected into a manageable form, such as a graph. Then, analyze and summarize the data, emphasizing trends and looking for strengths and weaknesses. Finally, interpret the data to find an answer to the original problem.
What are some examples in which the Pythagorean theorem is used in real life?

Most of the common use applications of the Pythagorean theorem relate to finding the shortest distance between two points. The hypotenuse of a right triangle is the diagonal line that bisects any regular rectangle, and the theorem is the only way of calculating the length of that diagonal without measuring. If someone is traveling 3 miles east, then 4 miles north, the length of a direct line from his starting point to his ending point is the square root of 3² plus 4², or 5 miles. If he is painting a wall 12 feet high, and the foot of the ladder needs to be 5 feet from the wall, then he knows..
