Answer:
D
Step-by-step explanation:
Answer:
answer is 107 degrees
Step-by-step explanation:
Given is a picture of triangle with vertices D, E and F
Given that exterior angle of F = 135 degrees
Hence interior angle of F =
Angle D = 28 degrees
Hence angle E =

Hence answer is 107 degrees
I'm pretty sure that you would divide 1000/200 and get 5 then multiply it by 74 to get 370. So 370 customers will probably order a salad.
Sorry if this is wrong I don't think that it is but just in case.
Answer:
The 95% confidence interval is between 26.5 ng/ml and 40.3 ng/ml
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 lower end of the interval is the sample mean subtracted by M. So it is 33.4 - 6.9 = 26.5 ng/ml
The upper end of the interval is the sample mean added to M. So it is 6.4 + 33.4 + 6.9 = 40.3 ng/ml
The 95% confidence interval is between 26.5 ng/ml and 40.3 ng/ml
