Answer:
Step-by-step explanation:
The fundamental step would be to determine the values of p and E which i believe is the margin of error in this case. Consider the following two equations;
We simply add the two equations and solve for p;
We then substitute this value of p in either equation and solve for E;
Since we have both p and E, the confidence interval can thus be written as;
l=51
m=78
n=51
n and l have the same value since it’s an isosceles triangle, so that’s why I doubled 4x-9
So hmm notice the picture below
the pyramid itself, is really, just one regular hexagon, at the bottom
and 6 triangles, stacked up at each other at the edges
now, if you just get the area of the regular hexagon, and the 6 triangles, add them up, that'd be the total surface area of the pyramid then
now, for the triangles, well, area of a triangle is 1/2 bh, as you'd know, and you have both
