Answer:
CV for A = 21.8%
CV for B = 15.5%
Step-by-step explanation:
The formula for coefficient of variation is:
CV = Standard Deviation / Mean
So,
For A:
Mean = Sum/No. of items
= 391300/14
=$27950
and
SD = $6085.31
CV for A = 6085.31/27950 * 100
=21.77%
Rounding off to one decimal
CV for A = 21.8%
For B:
Mean = Sum/No. of items
= 43.58/11
=3.96
and
SD = 0.615
CV for B = 0.615/3.96 * 100
=15.53%
=15.5% ..
Answer is C
2(x-5) -3(4x+4)
Multiply (x-5) by the 2
This makes it (2x-10) -3(4x+4)
Then do the same with the -3
This makes it 2x-10-12x-12
Simplify to make it -10x-22
Answer:
If x is the corner mostly and you said round it to the nearest tenth , rounding 9 to the nearest tenth would be 10 and same for 15.
Step-by-step explanation:
Answer:
X=60
Step-by-step explanation:
The little square near 150 means- that angle is right, i.e 90.
Like you can see, x, 30 and 90 are on the the same straight line, so the some of them is 180.
30+90+x=180
120+x=180
x=60
