Daniel is looking over the credit scores of a batch of potential new hires. their credit scores are compiled in the table below. what is the mode of this group of credit scores? (round to the nearest whole point, if applicable.)
812 769 744 812 688 725 744 744 801

a. 812
b. 744
c. 760
d. there is no mode in this group.

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.
