The formula for rule of 70 can be written as follows:t70gWhere t is the time it takes the economy to double and g is the constant percentage growth expected in future.DerivationIf an economy grows at a constant rate annual rate g, the value of its gross domestic product (GDP) after t...
The Rule of 72 dates back to 1494 when Luca Pacioli referenced the rule in his comprehensive mathematics book called Summa de Arithmetica.2Pacioli makes no derivation or explanation of why the rule may work, so some suspect the rule pre-dates Pacioli's novel.3 How Do You Calculate the Rule...
A simple derivation for the rule and an evaluation of its accuracy are presented. Results indicate the rule errs by less than l1/2 months for interest rates between 6 and 12 per cent, and by less than 21/2 months for rates between 5 and 21 per cent, and by less than 31/2 months ...
RESULTS. An admission hs-cTnI concentration < 5 ng/L had a negative predictive value (NPV) and sensitivity for 30-day MI or death of 99.5 - 99.7 and 98.1- 98.8%, respectively, in the derivation cohort and validation dataset. The NPV and sensitivity was ≥99.7% and ≥98.8% for ruling ...
of fractions with cascade structure.In this instance,the interclass number ratio is r_f=2.The total population of the first class is 1,second class,1/2+1/3≈0.8333,the third class,1/4+1/5+1/6+1/7≈0.7595,and so on.If the sequence number of a class is large enough,it will have...
of our analysis with results obtained on the lattice and with other recent evaluations of the Cottingham formula. A summary and conclusions are provided in Sect.25. The Appendices contain material concerning the operator product expansion as well as a detailed derivation of the sum rule for the ...

The prevalence of 0 to 25 percent seat belt use was 31 percent in the derivation set and 33 percent in the validation set. At the lowest quintile of score (-1 or less), the likelihood ratios were 4.18 and 3.31 in the derivation and validation sets, respectively. At the highest quintile...

Mathematically, this is the unique situation when Formula (8) is tractable, allowing for a closed-form derivation of the expected progress. However, the case did not receive much attention in the literature, since it corresponds to the worst case scenario (stagnation), calling for an emergency ...
