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

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

tube or goog would be a great resource to with that question

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
