<u>Given</u>:
The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)
The points are rotated 90° about the origin.
We need to determine the coordinates of the point C'.
<u>Coordinates of the point C':</u>
The general rule to rotate the point 90° about the origin is given by
Substituting the coordinates of the point C in the above formula, we get;
Therefore, the coordinates of the point C' is (-1,2)
Answer:
Step-by-step explanation:
Given
Success
Failure
Consecutive trials until S happens
Number of trials
For every possible outcome, the last 3 must be SSS. So, we have:
The only possibility here is:
because 3 trials implies that all outcomes must be S.
The only possibility here is:
because 4 trials implies that the first outcome must be F
The possibilities are:
because 5 trials implies that the first and the second outcomes must be FS or SF.
The possibilities are:
because 6 trials implies that the first three outcomes are: FFF, SSF and SFF
The possibilities are:
because 7 trials implies that the first three outcomes are: FFFF, FSSF and SSFF and FFSF (similar to (e))
