Answer:

He should buy the 4 x 10 rug because it has the larger area.

Step-by-step explanation:

To find the area of a rectangle or square, you multiply length by width (A=l x w). 5x7=35 and 4x10=40, so 4 x 10 has the bigger area.

You can find “hypotenuse” using Pythagorean to get the length of one of those steps, 12.5, and you get 150 when you multiply that number by 12 for each of the 12 steps

mina [271]

The correlation coefficient for the data in the table is A. –0.993

<h3>Calculations and Parameters:</h3>

Using this formula: $r = \frac{n(\sum xy)-(\sum x\sum y)}{\sqrt{n\sum x^2-(\sum x)^2}\sqrt{n\sum y^2-(\sum y)^2}}$

We would use x and y to represent the unknowns.

n = 4

We have,

∑x = 42,
∑y = 44.37 ,
∑xy = 461.3
∑x^2 = 446,
∑y^2 = 494

Putting these values in the formula $r = \frac{n(\sum xy)-(\sum x\sum y)}{\sqrt{n\sum x^2-(\sum x)^2}\sqrt{n\sum y^2-(\sum y)^2}}$ would bring the answer as. A. –0.993
