A pound is larger then a ounce
Answer:
No
Step-by-step explanation:
No it is not a perfect square because you can not factor it.
Answer:
y=1
Step-by-step explanation:
5y(2x-1)=y(x+2)+20, x=3
5y(2(3)-1)=y(3+2)+20
5y(6-1)=y(5)+20
5y(5)=5y+20
25y=5y+20
25y-5y=20
20y=20
y=20/20
y=1
The solution would be like this for this specific problem:
Given:
N = 256
Sample Mean = $35,420
Standard Deviation = $2,050
Find:
Standard Error of Mean = ?
The
formula for the standard error of the mean is:
<span>Om
= o / sqrt(N)</span>
<span>Om
= the </span>standard deviation of the sampling
distribution of the mean
where
o = standard deviation of the sampling distribution of a statistic
N
= sample size
<span>So
substituting the formula with the given:
Om = $2,050 / sqrt(256)</span>
<span>Om
= $2,050 / 16</span>
= $128.125
Therefore, the sample standard error of the mean is
$128.125.
