Newborn babies: A study conducted by the Center for Population Economics at the University of Chicago studied the birth weights of 746 babies born in New York. The mean weight was 3226 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 2390 grams and 4062
grams. Round to the nearest whole number.
The number of newborns who weighed between 2390 grams and 4062 is

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
