Answer:
NO
Step-by-step explanation:
This is because the sample should ideally be representative of the whole population. If the right sampling methods are used, the sample should well exhibit the properties of the whole population. The sample mean should be as precise as possible to the population mean , hence it is not unusual for the sampling to mean to be exactly the same as the population mean
Answer:
-8x
Step-by-step explanation:
Subtract 6°x from -2x.
The circumference of a circle is 2PiR or PiD (Pi being 3.14) ( 2 x Radius x 3.14).
We have the diameter, 6. The radius is 0.5d or d/2.
Our radius is 3.
3.14 x 2 = 6.28
6.28 x 3 = 18.84
Your circle's circumference is 18.84 mm^2.
I hope this helps! :)
