Newborn babies: A study conducted by the Center for Population Economics at the University of Chicago studied the birth weights of 673 babies born in New York. The mean weight was 2980 grams with a standard deviation of 836 grams. Assume that
birth weight data are approximately bell-shaped. Estimate the number of newborns who weighed between 2144 grams and 3816
grams. Round to the nearest whole number.
The number of newborns who weighed between 2144 grams and 3816 grams is

answer: ur v dumb

step-by-step explanation:

s

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.
