You need to look for the area to the left of the z-score from the table.
i found a z-score of.84 yielded .7995 area to the left of that z-score and i found a z-score of .85 yielded .8024 area to the left of that z-score.
0.7995 is much closer to 0.80 than 0.8024, so the z-score chosen as the solution is a z-score of .84.
the z-score of .84 is an addition of 0.8 in column 1 with .04 in column 7
it's the intersection of the area in the row of .8 with the column of .04.
this is shown in the following picture.
Answer:
b
Step by Step Explanation:
Well, there are 1760 yards in a mile
so then 1760 times 12 = 21120
The library is 21,120 yards from the post office
:D hope i helped
For any regular polygon, the area can be expressed in terms of its apothem
![a](https://tex.z-dn.net/?f=a)
and its perimeter
![p](https://tex.z-dn.net/?f=p)
like this:
![A =\frac{ap}{2}](https://tex.z-dn.net/?f=A%20%3D%5Cfrac%7Bap%7D%7B2%7D)
For the problem the apothem
![a=4\sqrt{3}](https://tex.z-dn.net/?f=a%3D4%5Csqrt%7B3%7D)
So we need to find the perimeter. A regular hexagon is built up by equilateral triangles, so the radius is equal to each side, therefore the perimeter is given by:
![p=6r=6(8)=48](https://tex.z-dn.net/?f=p%3D6r%3D6%288%29%3D48)
Finally, if we substitute in the first equation:
Answer:
93312
Step-by-step explanation:
We can use the geometric sequence formula
a= a1(r)^n-1
Substitute:
a=2(6)n^1
a=2 *6^n* 1/6
a=6^n*1/3
Substitute "7" for n:
a(7)=6^(7)*1/3
a(7)=93,312
