Answer:
Margin of error of 0.0485 hours.
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
.
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.
In this question:

The margin of error is of:



Margin of error of 0.0485 hours.
A large basket of apples weighed 10 2/3lb
Basket was 1 1/4lb
Apples weigh = 10 2/3 - 1 1/4
Apples weigh = 10 8/12 - 1 3/12
Apples weigh = 9 5/12
Answer
Apples weighed 9 5/12 lbs
Answer:



Step-by-step explanation:
Use the Triangular Interior Angles Theorem to figure this out:
180° = [7x + 1]° + [6x - 6]° + 55°
180° = [−5 + 13x]° + 55°
180° = [50 + 13x]°
-50° - 50°
____________
![\frac{130°}{13} = \frac{[13x]°}{13} \\ \\ 10° = x](https://tex.z-dn.net/?f=%5Cfrac%7B130%C2%B0%7D%7B13%7D%20%3D%20%5Cfrac%7B%5B13x%5D%C2%B0%7D%7B13%7D%20%5C%5C%20%5C%5C%2010%C2%B0%20%3D%20x)
You then plug this back into all three expressions to get 71° as the measure of ∠G and 54° as the measure of ∠T.
