The chart shows three health indicators for seven regions. Let U = the set of regions listed, A= the set of regions with male life expectancy that exceeds 75
years, B = the set of regions with female life expectancy that exceeds 80 years,
and C = the set of regions with fewer than 400 persons per doctor. Construct a
Venn diagram that illustrates these sets.

true !

step-by-step explanation:

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.

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
