Answer:
Step-by-step explanation:
From the figure attached,
Point B has been dilated to form point B'.
B(3, 1) → B'(6, 2)
→ B'[(2 × 3), (2 × 1)]
Since rule for the dilation of a point (x, y) by a factor of k is,
B(x, y) → B'(kx, ky)
By comparing the coordinates k = 2 is the scale factor by which the point B has been dilated about the origin.
Therefore, other vertices of the quadrilateral will be,
A(-2, 3) → A'(-4, 6)
C(1, -1) → C'(2, -2)
D(-3, -2) → D'(-6, -4)

In the data set below what is the lower quartile 16,26, 48,56,61,85,88,88,88,91,91
OlgaM077 [116]
Answer:
48
Step-by-step explanation:
First find the median:
16,26,48,56,61,85,88,88,88,91,91
85 is the median.
Now, find the median of the first set of bold numbers.
<u>16</u>,<u>26</u>,48,<u>56</u>,<u>61</u>
The median of the first bold set of numbers will be lower quartile.
The lower quartile is 48.
