Well I certainly understand why you are having grief. I wonder what we know about this thing? The bottom triangle is easy enough to figure out, but are the lines leading up to it parallel? If they are then 5.2 is not correct, or the right
angle symbol is meant to connect to the vertical line closest to us.
What's all the writing to the left and right. What does it say?
Finally what do you know? Can you find area using Heron's Formula for area. I'm going to hold off saying much. You can put a remark somewhere. The magic editor will pick it up and tell me you've done it.
Answer:
=8
Step-by-step explanation:
2²×2⁴÷2³
=2^2x2^{4-3}
=2^{2+4-3}
=2^3
=8
I hope this helps!

Answer:
The upper confidence limit of a 92% confidence interval for the population mean of grade point average is 2.93.
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 Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
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 upper end of the interval is the sample mean added to M. So it is 2.89 + 0.04 = 2.93.
The upper confidence limit of a 92% confidence interval for the population mean of grade point average is 2.93.
