The mean birth weight for children born in a certain country at full term (after 40 weeks) is 3422 grams
(about 75 pounds). Suppose the standard deviation is 450 grams and the shape of the distribution is
symmetric and unimodal. Complete parts a and b below.
a. What is the range of birth weights (in grams) of children born from one standard deviation below the
mean to one standard deviation above the mean?
The top value is
The bottom value is

$79500

step-by-step explanation:

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
