Equation for the line of best fit:


Each step of my work to find the equation:








What does the slope represent within the context of your graph?





What does the y-intercept represent?






Test the residuals of two other points to determine how well the line of best fit models the data.



Use the line of best fit to help you describe the correlation.




Using the line of best fit that you found in Part 3, Question 2, approximate how tall is a person whose arm span is 66 inches?

Reduce the fraction:<br> 7b-14b²/42b²21b
ch4aika [34]

Answer:

(1-2b)/126b^2

Step-by-step explanation:

(7b-14b^2)/(42b^2*21b)

factor out the 7b,

[7b(1-2b)]/882b^3

[7b(1-2b)]/[7b(126b^2)]

cancel out the 7b's

(1-2b)/126b^2

WXY is a right triangle. <br><br> A. True. <br> B. False.
lora16 [44]

Answer:

B. False


Step-by-step explanation:

According to pythagorean theorem, for this to be a right triangle, the sum of  square of the length of the two legs must equal square of the length of the hypotenuse (longest side).

So  (\sqrt{34} )^{2}  should equal  (\sqrt{18} )^{2}+(\sqrt{18} )^{2}

  • <em>We also know that  (\sqrt{a} )^{2}=(\sqrt{a})(\sqrt{a})=a</em>

Hence,  (\sqrt{18} )^{2}+(\sqrt{18} )^{2}=18+18=36  , and

(\sqrt{34} )^{2}=34

They ARE NOT EQUAL, so the triangle is NOT a right triangle.
