Point P is called the center of rotation
<h3 /><h3>How to determine the name of point P?</h3>The complete question is added as an attachment
The coordinates of the triangles are given as:
BCDE has points (2, 1), (2, 4), (4, 4), (4, 1).
B'C'D'E' has points (-1, 2), (-4, 2), (-4, 4), (-1, 4).
From the figure, we can see that the rectangle BCDE is rotated to get the rectangle B'C'D'E'
This rotation is done through the point P as a center of rotation
Hence, the point P is called the center of rotation

Answer:
12
Step-by-step explanation:
Given :
Male Female Total
Registered 60
Non registered 40
Total 20 80
Solution :
N= 100
Formula of expected frequency =
= expected frequency for the ith row/jth columm.
= total in the ith row
= total in the jth column
N = table grand total.
So, using formula
Expected frequency table
Male Female Total
Registered 12 48 60
Non registered 8 32 40
Total 20 80
So, the expected frequency for males who are registered voters are
Answer:
B. y= 1/2 x - 3
Step-by-step explanation:
base equation: y= mx+ b
slope(m) equation:
y2= -1 y1= -3
x2= 4 x1= 0
y- intercept: -3
found by taking the y from (0,-3)
