I can only help you with the second one. It is a positive correlation because it is going upwards. Good luck with the first one!
Yes you have the correct answers for each of the four problems. Nice work.
For anyone curious,
rd = removable discontinuity
id = infinite discontinuity
c = continuous
Answer:
Step-by-step explanation:
The first step to solving this problem is verifying if this sequence is an arithmetic sequence or a geometric sequence.
This sequence is arithmetic if:
We have that:
This is not an arithmetic sequence.
This sequence is geometric if:
This is a geometric sequence, in which:
The first term is 40, so
The common ratio is , so .
We have that:
The 10th term is . So:
Simplifying by 4, we have:
