Formula for Combination Mathematically, the formula for determining the number of possible arrangements by selecting only a few objects from a set with no repetition is expressed in the following way: Where: n– the total number of elements in a set k– the number of selected objects (the ord...
Repetitions are just repeating numbers. They become important when it comes to choosing the right formula. 123 has no repetitions (each of those numbers is unique). 223 has the number 2 repeated. Allowingrepetitiondepends on your situation. For example: ...
The formula for combination with repetition is as follows: C(n,r)=(r+n−1)!r!(n−1)!C(n,r)=r!(n−1)!(r+n−1)! and for permutation with repetition: P(n,r)=nrP(n,r)=nr In the picture below, we present a summary of the differences between four types of selection ...
From formula (2.1) there are 456 wettings with a 0.01 N solution of KCl. The wetting was done for 0.9 minutes at intervals of 1 hour. The results of laboratory testing (a degradation mechanism) and real life correspond only for variant 1 (Table 2.11). The variants (σ12 − σc2)≤...
Cisplatin is the first and most widely used platinum-based chemotherapy drug and is the cornerstone agent in treating a broad spectrum of cancers. However, its clinical application is often limited by severe toxic side effects and drug resistance. Based
IV can also be calculated using the formula:(6)IVNMR=MIodms.mDMSO2. PDMSO2MDMSO2.NDMSO2Ns(2).I−CH=CH− (5.37-5.27 ppm)IDMSO2 (2.98 ppm). 100 3.5. Polyunsaturated fatty acid, monounsaturated fatty acid, and total unsaturated fatty acid Recent developments related to the determination...
The effects of the YQJD formulae at that point had been verified with other indicators, such as the cerebral infarct volume, cerebral edema and mitochondrial function5. The neurological scores were assessed as described by Huang et al.40, and then the animals were euthanized. The researcher ...

In the formula, Te is the electron temperature, Ne is the electron density, ΔE is the upper and lower energy difference of the corresponding spectral line. In this experiment, the maximum electron temperature is 14260 K, the upper and lower energy difference is 1.67 eV. The limit of ...
A p-value of 2.05 × 10−6 was used to determine the significant associations and was calculated by the formula p-value = 0.05/N, where N (24,360) represented the number of effective SNPs calculated by the simpleM program in R [81]. All genes located in the LD regions around each...
