What Is The Relationship Between The Masses Of Oxygen And Hydrogen? A hydrogen atom has a mass of approximately 1 u. An oxygen atom has a mass of approximately 16 u. The ratio of the mass of an oxygen atom to the mass of a hydrogen atom is therefore approximately 16:1. How is oxygen and
What Is The Range Of Water Cement Ratio? The water-cement ratio of cementitious grout is usually in the range of 0.35–0.4. What should be the minimum water-cement ratio? The minimum water cement (w/c) ratio depends on factors like fineness of cement (Min 280 kg/m3), clinker used, Sp. gravity and grain size. Basically, min w/c ratio
What Does An Odds Ratio Of 1 Mean? If an odds ratio (OR) is 1, it means there is no association between the exposure and outcome. So, if the 95% confidence interval for an OR includes 1, it means the results are not statistically significant. What does a odds ratio of 0 mean? Odds-ratio The
What Does A Relative Risk Of 1.5 Mean? • This means if the relative risk was 1.5, people in Group A would be 50% more likely than people in all other groups to die from a cause. • Or if the relative risk were 3.0, people in Group A would be three times as likely
How Does The Golden Ratio Work? You can find the Golden Ratio when you divide a line into two parts and the longer part (a) divided by the smaller part (b) is equal to the sum of (a) + (b) divided by (a), which both equal 1.618. This formula can help you when creating shapes,
What Does A Hazard Ratio Of 1 Mean? A hazard ratio of one means that there is no difference in survival between the two groups. … A hazard ratio of greater than one or less than one means that survival was better in one of the groups. What does a hazard ratio of 0.5 mean?
What Does A High Surface Area To Volume Ratio Mean? An increased surface area to volume ratio also means increased exposure to the environment. … More contact with the environment through the surface of a cell or an organ (relative to its volume) increases loss of water and dissolved substances. Is a large surface area
What Is Constant K In Math? The constant value (often written k) relating amounts that rise or fall uniformly together. It is the ratio of the amounts y and x: k = y/x . What is the constant of proportionality K? When two variables are directly or indirectly proportional to each other, then their relationship
How Do You Calculate Odds Ratio In Logistic Regression? The odds ratio is calculated by dividing the odds of the first group by the odds in the second group. In the case of the worked example, it is the ratio of the odds of lung cancer in smokers divided by the odds of lung cancer
What Is The Meaning Of An Unknown Factor And Quotient? Unknown factors/variables are numbers/terms that would make an equation true. For example, in the equation x + 5 = 10, x is the unknown variable, and you want to find some number, which when added to 5 would result in 10. Quotients are answers to
