A large multinational corporation recently implemented an ERP system. A survey was done to determine the level of satisfaction with the new system. Out of 350 managers surveyed, 280 indicated that they were satisfied. At 95% confidence, what is the margin of error for the proportion of satisfied managers

this is false ^.^ lol

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.
