Guess the correlation coefficient, r. ​

Mathematics
1 answer:
sattari [20]3 years ago
8 0

Answer:

It would most likely be 0.9.

Step-by-step explanation:

The correlation coefficient ranges from -1 to 1 and is dependent on how strong the correlation is between the points. It cannot be 1.2 as it is above one and it cannot be 1 because all the points do not line up on the line of best fit. However, most do, so we can assume that there a strong positive linear relationship which means 0.9 would be the correct answer. The close r gets to zero means the less of a correlation there is. The line of best fit isn't negative so it cannot be -0.23 and it has a strongly positive correlation, not a weak one so it isn't 0.13.

A square desktop has an area of 324 square inches. What is the length of one side of the desktop
Sveta_85 [38]
Question: The area of a square is 324 square inches. What is the length of one side of the square?
The formula for finding area of squares is:

Length x Width

Squares have 4 sides, and all sides measure the same. If the area is 324 square units, that means the length and width are the same.

x X x=x2

X2=324

x squared(x²) is equal to 324. To find x, you have to do the opposite of squaring, which is finding the square root.

x2= 324 —> square root of 324=x

To find x, you have find the square root of 324.

Square root of 324 is 8

The length of one side is 18 inches
Check:
The formula for finding area is:

Length x Width

The length and width gotten was 18. Put that into the formula:

18 x 18

Multiply:

18 x 18= 324

That means the answer is correct. Your answer is 18 inches.
