The formulas obtained directly from the results of a quantitative analysis are called empirical, or simplest, formulas. In order to establish the molecular formula of a substance, it is necessary to determine the molecular weight of the substance. If this is not possible, only the empirical formu...
16.The formulae in common use for the calculation of capital cost rate are logical but defective. 常用的资本成本率计算公式既有其合理性,又存在一些缺陷。 17.Two performance index formulae are introduced to determine the optimum topology design. 引进了两种性能指标公式来确定最佳拓扑设计。 18....

The hypergeometric distribution is used to determine the probability of a certain number of "successes" in a series of draws made without replacement from a fixed population. The distribution depends on the size of the population, the number of draws, and the number of "successes" in the popul...
I want to compare multiple dates for Planning dates vs. Actual dates; it seems that in planning dates there are several activities inclusion same with actual dates. I need to compare it 1 by 1 activity date and the true values will determine the condition of green, amber and red. Reply ...
Lastly, determine whether the circle is free or fixed. Choose the equation based on those three factors. What is the formula for circular permutations? The formula for calculating a circular permutation without repetition is: n!/(r(n-r)!), where n is the total number of options to choose...
For vertical lookup, you use the MATCH function only to determine the row number and supply the column range directly to INDEX: INDEX(column to return a value from, MATCH(lookup value,column to look up against, 0)) Still having difficulties to figure that out? It might be easier to under...
However, we can determine easily the range of limit bounds of the R-order taking the limit cases n=2 and very large n. In the latter case the convergence rate of a single-step method becomes almost the same as that of the corresponding total-step method when the polynomial degree is ...
For a SUMIFS formula to work correctly, all thecriteria_rangearguments must have the same dimension assum_range, i.e. the same number of rows and columns. The SUMIFS function works with AND logic, meaning that a cell in the sum range is summed only if it meets all of the specified crit...
Choosing the order in which people finish a race. You can use factorials to determine the who comes in first, second, and third place, not to mention the order of the other participants. What Does a Permutation Mean? A permutation is a concept in math that outlines the number of ways in...
