B<span>oth triangles are 30 60 90 triangles.
Perhaps the way to prove this is by showing that (AD/BD) and (AD/ A1D) and (A1 A / AB) all equal (2 / Sq root (3)) = 1.155</span>
M2 -2mn + n2 =
4 - (-16) + 16 =
20 + 16 = 36
Have a nice days.......
Answer:
The confidence interval is 
, in which n is the size of the sample.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of 
.
That is z with a pvalue of 
, so Z = 1.96.
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 
The upper end of the interval is the sample mean added to M. So it is 
The confidence interval is , in which n is the size of the sample.
