X = number of atoms of carbon, Y = number of atoms of hydrogen, Z = number of atoms of oxygen, and M = number of atoms of metal (metallic oxide produced). In the case of TNT (C 6 H 2 (NO 2) 3 CH 3), Molecular weight = 227.1 X = 7 (number of carbon atoms) Y = 5 (number of hydrogen atoms) Z = 6 (number of oxygen atoms) Therefore,
This notation consists of symbols used for representing operations, unspecified numbers, relations and any other mathematical objects, and then assembling them into expressions and formulas. [94] More precisely, numbers and other mathematical objects are represented by symbols called variables, which are generally Latin or Greek letters, and ...
The answer is obviously in the negative. The parameter is an unknown constant, and no probability statement concerning its value may be made... A 95% confidence level does not mean that 95% of the sample data lie within the confidence interval.
A method analogous to piece-wise linear approximation but using only arithmetic instead of algebraic equations, uses the multiplication tables in reverse: the square root of a number between 1 and 100 is between 1 and 10, so if we know 25 is a perfect square (5 × 5), and 36 is a perfect square (6 × 6), then the square root of a number greater than or equal to 25 but less than 36, begins with ...
Water is an inorganic compound with the chemical formula H 2 O.It is a transparent, tasteless, odorless, [c] and nearly colorless chemical substance.It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent [20]).
Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within. A cell containing a formula, therefore, has two display components ...
For an object at rest, the energy–momentum four-vector is (E/c, 0, 0, 0): it has a time component, which is the energy, and three space components, which are zero. By changing frames with a Lorentz transformation in the x direction with a small value of the velocity v, the energy momentum four-vector becomes (E/c, Ev/c 2, 0, 0).
For example, the seller might drop the price of the product to $0.70 so that, after adding in the tax, the buyer pays a total of $1.20, or $0.20 more than he did before the $0.50 tax was imposed. In this example, the buyer has paid $0.20 of the $0.50 tax (in the form of a post-tax price) and the seller has paid the remaining $0.30 (in the form ...
