In mathematics, a rate is the quotient of two quantities, often represented as a fraction. [1] If the divisor (or fraction denominator) in the rate is equal to one expressed as a single unit, and if it is assumed that this quantity can be changed systematically (i.e., is an independent variable), then the dividend (the fraction numerator) of the rate expresses the corresponding rate of change ...
[The formula does not make clear over what the summation is done. P C = 1 n ⋅ ∑ p t p 0 {\displaystyle P_{C}={\frac {1}{n}}\cdot \sum {\frac {p_{t}}{p_{0}}}} On 17 August 2012 the BBC Radio 4 program More or Less [ 3 ] noted that the Carli index, used in part in the British retail price index , has a built-in bias towards recording ...
A simple unit is one which represents a single condition without any qualification. A composite unit is one which is formed by adding a qualification word or phrase to a simple unit. For example, labour-hours and passenger-kilometer. Unit of analysis and interpretation: units in terms of which statistical data are analyzed and interpreted.
In accounting, an extended cost is the unit cost multiplied by the number of those items that were purchased. For example, four apples purchased at a unit cost of $1 have an extended cost of $4 (=$1 × 4 apples). [1] By accurately tracking extended cost, a business can make more informed decisions about pricing, purchasing, and inventory ...
Here’s an example using the $100,000 loan with a factor rate of 1.5 and a two-year (730 days) repayment period: Step 1: 1.50 – 1 = 0.50 Step 2: .50 x 365 = 182.50
The traditional rate formula is intended to produce a utility's revenue requirement: R = O + (V − D)r. The elements of the traditional rate formula are defined as: R is the utility's total revenue requirement or rate level. This is the total amount of money a regulator allows a utility to collect from customers.
There are no statistics regarding quantity of future losses and probability. This means an underwriter rates each exposure individually. The second rate making method is class rating, or manual rating. This rating means that exposures with similar characteristics are placed in the same underwriting class, and each is charged the same rate. The ...
For example, in a community made up of primarily young couples, the birthrate might appear to be high when compared to that of other populations. However, by calculating the standardized birthrates that is by comparing the same age group in other populations), a more realistic picture of childbearing capacity will be developed.
