Answer:
The standard deviation of the sample mean differences is _5.23_
Step-by-step explanation:
We have a sample of a population A and a sample of a population B.
For the sample of population A, the standard deviation 
is
The sample size 
is:
.
For the sample of population B, the standard deviation 
is
The sample size 
is:
.
Then the standard deviation for the difference of means has the following form:
Finally
Answer:
-21/4x-1/2
Step-by-step explanation:
-1/2(-3/2x+6x+1)-3x
3/4x-3x-1/2-3x
3/4x-3x-3x-1/2
3/4x-6x-1/2
3/4x-24/4x-1/2
-21/4x-1/2
For this case we have the following number:
600,000
We can rewrite this number as the product of two numbers.
We have then, mathematically:
600,000 = 60 * 10,000
Then, rewriting in words we have:
600,000 = sixty - ten thousand
s
Answer:
Rewriting 600,000 we have:
600,000 = sixty - ten thousands
Answer:
27
Step-by-step explanation:
5×6-(6/2)
=30-3
=27
