In the figure, the fraction 1/9000 is displayed in Excel. Although this number has a decimal representation that is an infinite string of ones, Excel displays only the leading 15 figures. In the second line, the number one is added to the fraction, and again Excel displays only 15 figures. In the third line, one is subtracted from the sum using ...
Microsoft Corporation is an American multinational technology conglomerate headquartered in Redmond, Washington. [2] Founded in 1975, the company became highly influential in the rise of personal computers through software like Windows, and the company has since expanded to Internet services, cloud computing, video gaming and other fields.
The seats-to-votes ratio for a political party is the ratio between the fraction of seats and the fraction of votes for that party: a i = s i v i {\displaystyle a_{i}={\frac {s_{i}}{v_{i}}}} The Sainte-Laguë method approximates proportionality by optimizing the seats-to-votes ratio among all parties i {\displaystyle i} with the least squares ...
The moment generating function of a real random variable is the expected value of , as a function of the real parameter . For a normal distribution with density f {\textstyle f} , mean μ {\textstyle \mu } and variance σ 2 {\textstyle \sigma ^{2}} , the moment generating function exists and is equal to
The decibel originates from methods used to quantify signal loss in telegraph and telephone circuits. Until the mid-1920s, the unit for loss was miles of standard cable (MSC). 1 MSC corresponded to the loss of power over one mile (approximately 1.6 km) of standard telephone cable at a frequency of 5000 radians per second (795.8 Hz), and matched closely the smallest attenuation detectable to a ...
Some of the Bass-Model extensions present mathematical models for the last two (Maturity and Decline). MS-Excel or other tools can be used to solve the Bass model equations, and other diffusion models equations, numerically. Mathematical programming models such as the S-D model apply the diffusion of innovations theory to real data problems. [81]
When WTVJ opened a news bureau in Palm Beach County in 1970, 12.4 percent of its audience was said to come from there. [114] At one time, it outrated WPEC before the station improved and lost the distinction of being an "embarrassing No. 3 in a two-station market". [115] In 1980, WTVX built a new transmitting facility with a more southerly ...
