Answer:
Step-by-step explanation:
Solution,
Here
Mean=10
N=6
Efx=7+14+6+p+8+14
=49+p
Now
Mean=Efx/N
or,10=49+p/6 ( Therefore,10 is multiplied to 6)
or,60=49+p
or,p=60-49
p=11
Answer:
m = 7
m = -7
Step-by-step explanation:
Answer:
Yes, the ordered pair (0,0) is a solution of the system
Step-by-step explanation:
we have
----> inequality A
----> inequality B
we know that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities
<u>Verify</u>
For x=0,y=0
<em>Inequality A</em>

----> is true
so
The ordered pair satisfy inequality A
<em>Inequality B</em>

----> is true
so
The ordered pair satisfy inequality B
therefore
The ordered pair (0,0) is a solution of the system
