We are given a line with the following data:
r-value = 0.657 (r)
standard deviation of x-coordinates = 2.445 (Sx)
standard deviation of y-coordinates = 9.902 (Sy)
We are asked to find the slope of the line up to 3 decimal places.
To find the slope of the line, based on the data that we have, we can use this formula:
slope, b = r * (Sy / Sx)
substitute the values to the formula:
b = 0.657 * ( 9.902 / 2.445 )
Solve for the b.
Therefore, the slope of the line is
b = 2.66078, round off to three decimal places:
b = 2.661 is the slope of the line.
Answer:
b
Step-by-step explanation:
A^2 + B^2 = C^2 - Right Triangle Formula
8^2 + 7^2 = 6^2 - Plug it into the formula
64 + 49 = 36 - Solve
64 = 85 - Add B and C
21 - your answer
Hopefully this helps.
Answer:
C) The scale factor is 2
Step-by-step explanation:
The side length of the bigger pentagon is 2 times bigger than the smaller one, so C is correct.

Answer:
2√5
Step-by-step explanation:
The distance formula is useful for this.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((2 -(-2))² +(1 -3)²) = √(4² +(-2)²) = √20
d = 2√5
The length of segment PQ is 2√5.
