Answer:
(-2, -3)
Step-by-step explanation:
90° clockwise rotation:
(x, y) -----> (y, -x)
Let's apply this to our coordinates:
(x, y) -----> (y, -x)
(3, -2) -----> (-2, -3)
Simply make the old y-coordinate the new x-coordinate, and make the old x-coordinate negative and make the new y-coordinate.
Therefore, the coordinate of the new point is (-2, -3).

Answer:
x= -1.5, y= -1
Step-by-step explanation:
6x= -5+4y
x= (-5+4y) / 6
4((-5+4y) / 6) + 5y = -11
4(-5+4y) + 5*6y = -11*6
-20+16y+30y= -66
16y + 30y = -66+20 = -46
y(16 + 30) = -46
y= -46 / (16 + 30)
y= -46 / 46
y= -1
x= (-5+4(-1)) / 6
x= (-5-4) / 6
x= -9 /6
x= -1.5
Answer:
57
Step-by-step explanation:
There are 60 data altogether.
Therefore, n=60
50th percentile = 50%*(n+1)
=50/100*(60+1)
=30.5
This implies that the 50th percentile is between the 30th and 31st data
30th data= 57 ; 31st data = 57
since they are the same figure, 50th percentage = 57
