Control group.
A single or double blind study means that either the participants or the researchers or both does not know who is in the control group and who is in the experimental group. This, there has to be a control group
The answer is (-2, -6)
to rotate 90 degrees counterclockwise, you do (-y, x)
Equation for the line:
Two points (-2,0) and ( 0,5)
Slope = (5-0) / (0 - -2) = 5/2
Y intercept = 5
Line = y = 5/2x + 5
Area to the right is colored and the line is solid.
Answer: y >= 5/2x + 5
Answer: The correct option is
(D) The sequence is not arithmetic because the terms do not have a common difference.
Step-by-step explanation: We are given to select the true statement regarding the sequence that is graphed in the figure.
From the graph, we see that some of the points are (1, 1), (2, 4), (3, 9), (4, 16), (5, 25).
That is, if we write the graphed points in terms of a sequence <a(n)>, then we get
The sequence <a(n)> will be arithmetic if the difference between the consecutive terms is equal. That is, the terms should have a common difference.
Now,
This implies that the terms do not have a common difference and so the graphed function does not represent an arithmetic sequence.
Thus, the sequence is not arithmetic because the terms do not have a common difference.
Option (D) is CORRECT.
