Answer:
Mean= 10.83
Median= 9.5
Step-by-step explanation:
Given number,
10, 15, 8, 11, 9, 12
N= 6
As we know,
Mean= Ex/N
=10+15+8+11+9+12/6
=65/6
=10.83
Therefore, Mean= 10.83
Now,
Median(MD)= (N+1/2)th item
= 6+1/2
=7/2
=3.5th item
So, Median(MD)= 3th+4th/2 item
= 8+11/2
= 19/2
= 9.5
Therefore, Median= 9.5
To solve 2/3 of 12 we need to divide 12 by 3 which is 4 so then we need to do 4 x 2 which is 8. Hope I helped.
Answer:
yes
Step-by-step explanation:
Y=mx+b
in you're equation -1/2 is you're slope and 1/4 is what is going by
m=slope
b=moving by

Answer:
x = -10/6 or - 5/3 (in lowest terms)
Step-by-step explanation:
To solve 2(x + 3) = -4(x + 1) for x:
Distribute 2 into (x + 3), and -4 into (x + 1):
2(x + 3) = -4(x + 1)
2x + 6 = -4x - 4
Add 4x to both sides:
2x + 6 + 4x = -4x + 4x - 4
6x + 6 = -4
Subtract 6 from both sides:
6x + 6 - 6 = -4 - 6
6x = -10
Divide both sides by -6:

x = -10/6 or - 5/3 (in lowest terms)
