g We want to test whether the mean lead levels in the drinking water is worse in city A and City B. In order to test this, a sample of 49 different water samples was taken from city A, and a sample was taken from 36 different water samples in city B. City A has a sample average of 2.3 micrograms of lead per deciliter of water, and city B has a sample average 1.4 micrograms of lead per deciliter of water. Further, city A has a known standard deviation of , and city B has a known standard deviation of . Find the p-value for the following hypothesis test: vs .

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

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 "
