Answer:
3)
i) 
ii) 
4)
i) 
ii) 
Step-by-step explanation:
We perform a simple linear regression analysis in megastat software to determine the line of best fit for both relations and their associated correlation coefficients.
A scale factor of 1/2 makes the triangle half the size of the original.
The original is 4 units tall, so 1/2 scale makes the new one 2 units tall.
It is 6 units long, so 1/2 would be 3 units long.
Now since the scale factor is centered at (-1,3) fine the midpoint between The top left corner of the triangle and the center point:
Midpoint ( -1-5/2 , 3+7/2)
Midpoint = (-6/2 , 10/2)
Midpoint = -3,5
This is where the top left corner of the scaled triangle would be.

difference is 2
Answer:
235
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 9*12.5=112.5
rec 2: (13.5-5.5)*(19.5-9-7)=28
rec 3:7*13.5=94.5
Then:
112.5+28+94.5=235
Answer:
Line
intersects line 
Step-by-step explanation:
We are given that


Subtract one equation from other then we get



Substitute the value of x in first equation then we get

Hence, the solution
is the intersection point of two line equations .
Answer:Line
intersects line
