Answer:
A
Step-by-step explanation:
As the sample size n increases, the sample mean (μy) becomes a more accurate estimate of the parametric mean, so the standard error of the mean becomes smaller. Therefore, the variance of y decreases and the distribution of y becomes highly concentrated around μy.
Answer:
46
Step-by-step explanation:
Multiply the two by both numbers inside the parenthesis
2 x 6 = 12 2 x 15 =30
Add those numbers together
12 + 30 = 42
Then add the remaining four to that number
4 + 42
Simplify 4^4 to 256
256 + 1/2 = 256.5
Simplify 256 + 1/2 to 513/2
513/2 = 256.5
Since both sides equal, there are infinitely many solutions.
Answer:
0.1
Step-by-step explanation:
The <em>common ratio</em> of a sequence is the number you multiply one term to get the next one. Here, we multiply 0.1 by 0.1 to get 0.01, and 0.01 by 0.1 to get 0.001, so our common ratio is 0.1.
