Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 900 grams while babies born after a gestation period of 40 weeks have a mean weight of 3100 grams and a standard deviation of 460 grams. If a 33​-week gestation period baby weighs 2575 grams and a 40​-week gestation period baby weighs 2975 ​grams, find the corresponding​ z-scores. Which baby weighs less relative to the gestation​ period?

see below

Step-by-step explanation:  5 16  9 34

this a fairly simple calculation once you know the formula for z score, but understanding the z scoring is more confusing

z  = ( x - μ )  / δ       μ mean of the sample,   δ  standard deviation of the sample

                              x is the observed value to check the z score

32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 900 grams

z  = ( x - μ )  / δ      33​-week gestation period baby weighs 2575 grams

   = (2575 - 2700) / 900

   =  -0.138

gestation period of 40 weeks have a mean weight of 3100 grams and a standard deviation of 460 grams.

z  = ( x - μ )  / δ      40​-week gestation period baby weighs 2975 ​grams

   = (2975 - 3100) / 460

   =  -0.272

Which baby weighs less relative to the gestation​ period?

A z-score close to 0 says the data point is close to average.

based on that the 33 week baby is closer to average

the 40 week baby is farther from average

hence the 40 week baby weighs less relative to the gestation period

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
