Answer:
(E) None of the above
Step-by-step explanation:
The statistic provided is that of the population but the statistic you seek is that of the sample.
Looking at the statistic itself, Variance is the square of Standard Deviation or standard deviation is the square root of variance.
Hence you calculate the standard deviation of the population mean:
√144 = 12
The population standard deviation of/from the mean value is 12.
It could be possible to decipher the sample mean from population mean but not sample size.
So, you can't pick just any answer. Population size should be given first.
Answer:
-8 and -3
Step-by-step explanation:
Add 11x to both sides;
x + 3 = 0
Subtract 3 from both sides;
x = -3
x + 8 = 0
Subtract 8 from both sides;
x = -8
Answer:
Always
Step-by-step explanation: because I did it and got the answer right
The perimeter is 2.5+ 2.5+2+3.5= 10.5 ft
The area is equal 6. I used the equation A= a=b/2*h

Answer:
see below
Step-by-step explanation:
Clearly, if you turn the figure sideways or upside down (rotate 90° or 180°), you do not have the same figure. It has no rotational symmetry.
However, if you reverse it left-to-right, you get exactly the same figure. So, it has line symmetry about a vertical center line.
