SAMPLE AND SAMPLING TECHNIQUE Sample ▪ Is a finite number of an item (or individual) taken from a population having identical characteristics with those of the population from which it was taken. ▪ A sample is considered biased if one or several of the items (or individuals) in the population are given a consistently better opportunity to be chosen than the others. ▪ A collection with specified dimension Sample size ▪ Random sampling‚ the larger the sample‚ the

forced damped transverse vibration of a beam and verify Dunkerley’s empirical formula. According to Dunkerley’s empirical formula‚ 1f2=1fb2+1fω2 where f referring to the natural frequency of heavy beam with central load fb referring to the natural frequency of heavy beam only fω referring to the natural frequency of light beam with central load M By using the results of light damping‚ Dunkerley’s empirical formula would be studied and verified by comparing the calculated resonant frequency

The Hubbart Formula Where would a hotel manager start in determining the fair price for a guest room? What is a fair value? This question has daunted innkeepers from the beginning. Charge rates too high‚ and no one will stay with you. Setting rates too low‚ and the owner makes less money. For many years in the beginning of the modern hotel era‚ hotel managers simply guessed. As unscientific as this approach sounds‚ it did work to an extent. After a hotel has been in business

prevent buckling if the temperature range is -30Cº to +50Cº? I know I use the formula: L = LoT L = ? (Change in length of the slabs. We are solving for this.) = 12e-6 (Coefficient of expansion. I looked it up on page 388.) Lo = 14 m (Initial length of slabs.) T = 30 Cº (50Cº - 20Cº) (Change in temperaure. You only care about the hottest number since you are dealing with expansion.) I then had the formula: L = e14 m 30Cº L = .00504 m L = .50 cm The space between

Heron’s Formula History of Mathematics University of Phoenix October 22‚ 2012 The event that I chose to discuss is Heron’s method that was written about in the three book series called metrica discovered in the period of about 60 AD. His formula for calculating the area of a triangle was one of the formulas which was written about in the books. Heron of Alexandria was also very well known by Hero. Their has been much debate on the birth

Title: Formula of a Hydrate. Objective: Determining the percentage of water and the chemical formula of a hydrate. Background: Water has a polar structure and it has positively and negatively charged parts within each molecule. This gives it a strong attraction toward ions. The ions in some salts attract and form strong bonds with water molecules. These salts‚ when they have absorbed water‚ are called hydrates. Anhydrous salts are salts that can form hydrates but which have had all the water

Six-Gun Mystique. His description of the Western formula being “far easier to define than that of the detective story” may clearly be a paradigm for many authors‚ but not particularly for Stephen Crane. The standards Cawelti has set forth for a successful Western is quite minimal by thought‚ but at the same time relevant. Crane signifies a different perspective to these standards. Crane’s thoughts for the use of the Western formula are just approaches towards the west‚ from the
