The most likely correlation coefficient for the set of data shown is: -0.21.
<h3>Correlation coefficient</h3>
We would be using CORREL in excel to determine the correlation coefficient by inputting the set data below
X Y
A (1,4)
B (2, 1.5)
C (3,3)
D (4,4)
E (5,2)
Hence:
Correlation coefficient=-0.20801
Correlation coefficient=-0.21 (Approximately)
Therefore the most likely correlation coefficient for the set of data shown is: -0.21.

The perimeter of the square is:
ft
Step-by-step explanation:
The picture is attached with the answer.
the diagonal of a square divides it into two right angled-triangles.
We can use one of the triangle to find the length of side as the diagonal will be the hypotenuse of the triangle
Let a be the side of the square, then according to Pythagoras theorem

Dividing both sides by 2

Taking Square root on both sides

Now,

Hence,
The perimeter of the square is:
ft

Answer:
i don't know lol
Step-by-step explanation:
it would be better to guess
(x; y)
The domain is x.
The range is y.
Therefore
(4; -4) → x = 4; y = -4
(2;-3) → x = 2; y = -3
(-5; 1) → x = -5; y = 1
if is (-4; -1) not (4; -1) then
(-4; -1) → x = -4; y = -1
The DOMAIN = {-5; -4; 2; 4}
The RANGE = {-4; -3; -1; 1}
If is (4; -4) and (4; -1) then it is not a function.
