What is the name of the method for drawing a trend line for the data in a scatterplot?
There are many methods, though the most popular is the method of least squares. This method minimises the sum of the squares of the vertical distances between each point and the corresponding point on the line.
What are the disadvantages and disadvantages of least square method?
The disadvantages are that the calculations required are not simple and that the method assumes that the same linear relationship is applicable across the whole data range. And these are the disadvantages of the least squares method.
Which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring?
Here are two ways to know if a given quadratic equations can be factored (can be solved by factoring). 1. Calculate the Discriminant D = b^2 - 4ac. When D is a perfect square (its square root is a whole number), then the given equation can be factored. 2. Solve the equation by using the new Diagonal Sum method (Amazon e-book 2010). This method directly finds the 2 real roots without having to factor the equation. Solving usually requires fewer than 3 trials. If this method fails to get the answer, then we can conclude that the equation can not be factored, and consequently the quadratic formula must be used.
Can a linear trend line can be obtained by using a least square method rather than a scatter diagram method?
A scatter diagram will give a quick but rough extimate of the trend line - especially if there is a lot of variation about the trend. The least squares method will be more accurate.
What is the difference between Average method vs weighted average method?
in weighted average method we assigns the weight to the averages while in average methods we dnt do this
Is it possible for you to use trial and error method or the X-method to factor the difference of two squares?
No it is not. At least, not sensibly.
What are the methods for factoring?
gcf difference of two squares guess ad check/ box method
Is the foil method used for factoring quadratic equations?
Yes FOIL method can be used with quadratic expressions and equations
What is factored form?
the form of an expression compossed of products of factors, rather than sums or differences of terms. the expressions x(x-2) and (x+3)(x+4) are in factored form. y=(x-2)(x+5), or factored form, is an equation that describes a parabola. Once factored, using a FOIL method, it becomes standard form. y=(x-2)(x+5) y=x^2+5x-2x-10 y=x^2+3x-10
How are computer simulation estimated in order of size?
A common method is to grade them by the order of the largest matrix that has to be factored.

What is the foil method of (x plus 3)(x minus 3)?
Using FOIL: (x+3)(x-3) equals x^2 -9 which is the difference of two squares
Which is found in the last step of the least-squares method?

Will the substitution method always work?
No, it will not.There are some expressions for which no analytical solution exists.
If you are given a quadratic relationship in factored form how can you find an equivalent expression in expanded form?
you have to use F.O.I.L method to simplify it.
