Answer:
-3
Step-by-step explanation:
Because slope is rise over run.
Rise = -3
Run = 1
Rise/Run = -3/1 = -3
Step-by-step explanation:
Find
Triangle A(because there are two triangles)
take 28°+39°=67°
an angle is 180° in total so you take
180°-67°=113°
Angle x = 113°
Angle y = 67°
Triangle B
64°+67° = 131°
180°-131°=49°
Angle z =49°

Answer:
The margin of error for a 90% confidence interval for the mean banking fee is of $0.44.
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 = 1.645.
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.
Sample of 31:
This means that 
Assume the population standard deviation is $1.50.
This means that 
Calculate the margin of error for a 90% confidence interval for the mean banking fee.

The margin of error for a 90% confidence interval for the mean banking fee is of $0.44.
