Which of the following is true of BLUE? a. An estimator is linear if and only if it can be expressed as a linear function of the data on the dependent variable. b. It is the best linear uniform estimator. c. It is a rule that can be applied to any one value of the data to produce an estimate. d. An estimator is an unbiased estimator of if for any .

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

what is the original number? you forgot to add it.

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
