of Pound per Week According to Drip & Dry (2014), R-Coefficient of correlation=-0.05779 Having coefficient of correlation, which is equal to -0.05779, means that the two variables are inversely proportional. This means that if one variable increases another decreases. For this case, when pounds of laundry a household increases, the likelihood of using the service decreases. R-Square= 0.00334 According to MathBits.com (2015), Coefficient of determination measures how well the linear…

It can be observed that the estimated coefficients of all the first order terms were significant. Also, while labour and seed had the expected positive sign, farm size had a negative sign. In the case of the squared variables, there is a different scenario, as both farm size and seed squared maintain…

Biostatistical analysis was carried out to study the association of each factor with the type of dental plaque (biofilm formation). Table 1 represents the biostatistical analysis of the survey of the patients from urban region. Based on the contingency coefficient value it was observed that “age, gender, food habit, diabetes, use of toothpowder, mouthwash” were least associated factor that influences the type of biofilm formation in patients from rural…

In this experiment, key drag forces are the skin drag and pressure drag. The skin drag and pressure drag can be accumulated to get the total drag. The drag coefficient is the ratio of the drag force formed in comparison to the product of the dynamic pressure and area. It is a dimensionless quantity. The factors that affect the drag coefficient is the shape of the body, the roughness of the surface, the viscosity of the fluid and compressibility of the object. The viscosity of the fluid…

Given a level of fiscal stimulus one can wonder how to allocate that optimally to reduce as much as possible inequalities in a population. We can rewrite the Gini coefficient formula to make it simpler to analyse. We will now consider that the X suite is sorted in such a way that X is increasing (not necessarily strictly). Also, suppose that the first N terms of X are equals. (Since N can be equal to 1, that is if only the first term is equal to itself, the case we are considering is still the…

From the Bering Strait to the connection between the Hill Center and the Engineering Building, bridges have been used for thousands of years to connect people with places. As people began building bridges, they have to consider not only the structural integrity of the bridge for the safety of the passengers crossing the bridge. With the invention of cars, even more safety precautions must be enacted to keep everyone safe. A car is being driven on a windy day has a higher chance of turning over…

study sliding friction and to determine the coefficients of static and kinetic friction. Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object. Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is given by…

in 2011, it will be found in the correlation coefficient, which is represented by “r”. The correlation coefficient for the data is r=0.815. The correlation is telling us the direction, strength, and linearity of the regression line to the data point. Based on the 0.815 is a positive number, the direction is positive and it can be…

Our coefficients evaluate whether an explanatory variable has a negative or positive impact on criminal recidivism. Based on the AFT model, a coefficient with a negative impact on the survival time makes the event faster while a positive impact seems to prolong the survival time. Therefore, it decelerates the time until the event happens again. In this case the coefficients evaluate the acceleration of deceleration of a criminal on being jailed again. The explanatory variable denoting whether…

This leads to the definition of conclusions The activity coefficients of sulfur and aluminum will be calculated by using the interaction parameters (which is equal to fS = 0.71, fAl = 1.13), we can estimate the degree of desulphurization of the investigated melt. Equation (6) shown, that increasing temperature resists…
