Answer:
Step-by-step explanation:
Sample variance when large number of samples are drawn we have tend to become a normal distribution.
Variance of the sample is different since variance
Var(x) = E(x^2)-{E(x)}^2
is the formula used for finding the variance of any sample.
But sampling distribution of variance requires repeating this process with the different samples several times.
So option A is not right
B is also not correct, C is wrong
D.The sampling distribution of the mean requires multiple samples to be compared. However, in this situation you are looking for the variance, so finding the sample variance is the same as investigating the sampling distribution of the variance.
is correct
A, because parallelogram is the same as a rectangle, just tilted a bit. therefore the method is just base X height.
Answer:
Bottom Right Graph (Absolute Value)
General Formulas and Concepts:
Step-by-step explanation:
When we apply the VLT to the 4 different graphs, we see that the only graph that actually passes the VLT is the absolute value graph. Therefore, that is our answer (none of the other graphs pass the VLT).

Answer:
52.94 miles per unit
Step-by-step explanation:
The unit rate is found by dividing miles per time
90 miles /1.7 unit
52.94117647 miles per unit
