Answer:
Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while
Correlation Coefficient r value of 0.80 means a strong positive relationship
Step-by-step explanation:
Correlation Coefficient (r) signifies the strength of relationship which exists between two linear variables. The value of r ranges from - 1 to + 1 where positive and negative values signifies a positive and negative relationship relationship respectively.
The closer the r value is to either +1 or - 1, the greater the strength of the relationship while a r value of 0 means, there is no relationship between the two variables.
Hence in the scenario above :
Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while
Correlation Coefficient r value of 0.80 means a strong positive relationship
My other answer got deleted.. I did answer your question, but whatever.
You are correct, the answer is D. a reflection across y = x then a positive rotation of 270 degrees about the origin.

Answer:
67 million square miles
Step-by-step explanation:
The area of a sphere is given by ...
A = 4πr²
So the area of the Earth is approximately ...
A = 4π(4000 mi)² ≈ 2.01×10^8 mi²
The area of the 1/3 that is not covered by water is approximately ...
(2.01×10^2 mi²)/3 = 6.7×10^7 mi²
The land area is estimated to be about 67 million square miles.
X= -2-x+6
2x=4
x=2
y=-2-2
y=-4
To get the area, you need to multiply length and width together.
2052/54 = 38
38 is your width
38 (width) x 54 (length) = 2052 (area) True
hope this helps
