Answer:
The approximate solution of the system of equations is the point (-2.7,2.1)
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (-2.714,2.143)
see the attached figure
therefore
The approximate solution of the system of equations is the point (-2.7,2.1)

Answer:
Follows are the solution to the given points:
Step-by-step explanation:
In point A:
In point B:
In point C:
For df = 70, the top 5% critical t score
tcrit = 1.666914479
Thus,
In point D:
For df = 70, the top 5% critical t score
tcrit = -1.666914479
In point E:
The lower cutoff is 0.10 in the center, which would be around 80 %. The critical point therefore is
tcrit = -1.293762898
In point F:
The lower cutoff is 0.90 in the center, which would be around 80 %. The critical point therefore is
tcrit = 1.293762898
