Margin error of a sample mean is given by
where σ is the standard deviation,
is the critical value and n is the sample mean.
So beside the given standard deviation, we're supposed to know the sample size and critical value to answer this question.
Answer:
Its D because the x axis can repeat itself
Step-by-step explanation:
A function is a relation in which the members of the domain (x-values) DO NOT repeat. So, for every x-value there is only one y-value that corresponds to it. y-values can be repeated.

Step-by-step explanation:
I have included attachment below
so since a rhombus is 2 pairs of paralell sides, we can cut it into 4 triangles
we can see that we can take the bottom 2 triangles and put them on top to get a rectangle that is width 21 and height 32/2 (16=height
area of rectangle=legnth times width=16 times 21=336 m^2
answer is 336 m^2
