In regression analysis, the technique used to determine the best-fitting line by minimizing the vertical distances of all the points from the line is called

step-by-step explanation:

faster, im not sure why but i know it is faster

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

b is the correct answer
