In a regression analysis involving 25 observations, the following estimated regression equation was developed. y-10- +3x2+ 14xalso, the following standard errors and the sum of squares were obtained. sb1 = 3 sb2 = 6 sb3 = 7sst = 4,800 sse = 1,296refer to exhibit 13-9. the coefficient of x2is significantis not significantcan not be tested, because not enough information is providednone of these alternatives is correct.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
