Answer:
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
s=5 represent the sample standard deviation
n=130 represent the sample size
For this case we can't set a margin of error just with a % since they not specify 1.13% respect to something for this case we can omit this value
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence level is 0.99 or 99%, the significance would be 
and 
, and the critical value would be 
And replacing we got:
Answer:
it is an undefined slope meaning it has no slope or change so there is no equation
Step-by-step explanation:
I have taken a class on this but if it only goes straight up and down it is undefined
Answer:
p = 30
Step-by-step explanation:
EFGH is a cyclic quadrilateral ( all vertices lie on a circle )
The opposite angles of a cyclic quadrilateral are supplementary, thus
p + 5p = 180
6p = 180 ( divide both sides by 6 )
p = 30
Answer: Inconsistent.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
Solve for "y" in each equation:
<em>Equation 1</em>
<em>Equation 2</em>
<em> 
</em>
<em> </em>
You can notice that the slope of the <em>Equation 1 </em>is:
And the slope of the <em>Equation 2 </em>is:
Observev that 
, then you can conclude that the lines are parallel and the System of equations has No solution.
When there is no solution the classification of the system of equations is: "Inconsistent".
<em> </em>
Y=mx+b
They give you the slope - 1/5
y=-1/5x+b
Now plug in the two coordinates of x and y to find b
7=-1/5(-5)+b
7=1+b
b=6
So the answer is y=-1/5x+6
