Step-by-step explanation:
10x-12=-120

Hello Missjay12,
Step 1 :
From the coordinates we have to find the slopes and midpoints of the lines.
Step 2 :
Find the slope of the bisectors and now find the equations of two lines by using slope and one mid points.
Step 3 :
Solve any two pair of equations and find the intersection point.
Step 4 :
The point thus found is the circumcenter of the given triangle.
so<span> the coordinates of the circumcenter of a triangle with vertices A(−3, 3) , B(−1, 3) , and C(−1, −1)</span> is, -4, 0.
Step-by-step explanation:
Length of arc of a circle is given as:

Thus, the measure of central angle is 140°.
Answer:
Step-by-step explanation:
Given that confidence level is 95% and sample mean is within 10 minutes of the population mean. i.e. margin of error = 10
Std deviation of population= 211 minutes
Margin of error = Z critical * std error
Std error = sigma/sq rt n = 
Hence we have
\frac{211}{\sqrt{n} }
The minimum sample size is 1710
