What is the coefficient of the second term (b) on the right-hand side of the equation (4a + 5)^2 = 16a^2 + ba + 25?Solving Equations:In order to solve an equation, it is important that we know how to manipulate the equation using...
What is the coefficient of {eq}x^2 {/eq} in {eq}(x + \frac{1}{x})^{10} {/eq}? Binomial Theorem: Suppose we have a number and its reciprocal. The {eq}n{/eq}th power of their sum can be expressed by the binomial theorem as follows: $$\begin{align} \left[x + \left...
First, he points out that “a” is the coefficient of x^2, and that b is the coefficient of x.He next explains the importance that these coefficients play: in an aerospace engineering role, you will have many different coefficients, and the equation would look drastically different if you ...
Definition:The coefficient of variation, or CV, is a statistical measurement that shows how a set of data points is distributed around the mean of the set. In other words, a set of data is graphed and the CV equation is used to measure the variation in points from each other and the ...
It should be easy to deduce that rheometers are far more sophisticated instruments than viscometers; the latter is built for specific types of fluids which we will discuss shortly.Newtonian and Non-Newtonian Fluids The Formula of Coefficient of Viscosity Lesson Summary Register to view this lesson...
Do social factors have an influence on mental disorders? What is correlation coefficient? What factors contribute to Classroom Culture? What are pull and push factors in international immigration? Specifically, what are the push and pull factors of the immigration from Mexico to the United States?
Adjusted R2is a special form of R2, thecoefficient of determination. The adjusted R2 has many applications in real life. Image:USCG R2shows how well terms (data points) fit a curve or line. Adjusted R2also indicates how well terms fit a curve or line, but adjusts for the number of ter...
After determining the form factor, the ballistic coefficient can be determined as a mathematical equation. The mass of the bullet, its form factor and a diameter of the bullet are used in the calculation. A ballistic coefficient can vary greatly above or below one for different bullet designs,...
