Step-by-step explanation:

where,



This represents a weak negative correlation
Answer:
Choice box 1: Always
Choice box 2: exactly 2 pairs
Choice box 3: adjacent
Step-by-step explanation:
If you look at a picture of a kite.
You always see the two top sides the same size and the two bottom sides the same size. Take a look at this picture.
Consider the given equations:
The first equation is as:

So, 
= 
Multiplying the given fractions, we get as
= 
Now, consider the second equation as:

Multiplying by '3' to both the sides of the equation, we get


So, the number which best completes both the equations is
.
A = (B + b)xH : 2
A = (4.5+7.5) x 5 : 2
A = 12 x 5 : 2
A = 60 : 2
A = 30 in²
Answer:
D
Step-by-step explanation:
since it tells you y is=1 plug that into the top equation
-1=5x+4
-1=x
and you already have y=-1
so its(-1,-1)
