Answer:
(-7, -3)
Step-by-step explanation:
So the formula is (x, y) --> (-y, x) for a 90 degrees counterclockwise rotation.
To apply this formula to (-3,7), first identify which is the x-coordinate and which is the y-coordinate.
x-coordinate is -3 & y-coordinate is 7
Then you literally just substitute it into the formula like so:
(-y, x) -->(-(7), (-3)) --> (-7, -3)
Try to put parantheses around the coordinate when substituting to prevent confusion & incorrect negative signs.

Answer:
Option B is right
Step-by-step explanation:
given that the distribution of 27 salaries at a small company has mean $35,000 and standard deviation $2,000.
When an extreme outlier such as 120000 is included for 28th employee we find that mean would jump up.
Since original median was 14th item, now with one more, new median would be average of 14th and 15th. Hence median may change.
Range will definitely change because maximum shifted up to 120000
Hence we can say
mean increases , median change and range changes.
Hence we find that Option B is right.
