Answer: an = 4n + 1
Step-by-step explanation:
Use the formula an = a1 + d (n - 1) to identify the sequence
I think it’s C if you still need an answer but don’t trust me on that
Answer:

We also know that we select a sample size of n =100 and on this case since the sample size is higher than 30 we can apply the central limit theorem and the distribution for the sample mean would be given by:

And the standard deviation for the sampling distribution would be:

So then the answer is TRUE
Step-by-step explanation:
Let X the random variable of interest and we know that the true mean and deviation for this case are given by:

We also know that we select a sample size of n =100 and on this case since the sample size is higher than 30 we can apply the central limit theorem and the distribution for the sample mean would be given by:

And the standard deviation for the sampling distribution would be:

So then the answer is TRUE
Answer:
YES
Step-by-step explanation:
As x increases by 3 each time, y also increases by a steady number each time, which is 6. This means that x and y are in a proportional relationship with a 1:2 ratio.
