Answer:
Step-by-step explanation:
1,2,3,(4),5,6,7
median (middle number) or Q2 = 4
Q1 (lower quartile) = 2
Q3 (upper quartile) = 6
IQR = Q3 - Q1 = 6 - 2 = 4
The answer to the question is 28
but if you want negative, then its -28
This is a reduction because the scale factor is in between 0 and 1.
The coordinates of A in the pre-image is (-1,2).
D0, 3(x,y) means (x,y) → (3x,3y)
A'(-3,6)
B'(-0.5, 8)
C'(2,6)
D'(1,3)
E'(-2,3)
The coordinates of the pre-image are multiplied by 3 resulting to the coordinates of the given image. So, we simply divide each value of x and y by 3 to get the coordinates of the pre-image.
A'(-3,6) → -3/3 = -1 ; 6/3 = 2 → A(-1,2)
