<em><u>"Correlation Coefficient" is the value from between -1 and 1 indicates the strength of the correlation between two variables.</u></em> Galton calculated the correlation coefficient for the line of best fit, to see how strong the relationship was. Hope this helps you! Thank you for posting your question at here on Brainly. Have a great day. -Charlie

Answer:
45.5
Step-by-step explanation:
First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.
There is a designated formula for this circle drawing. This is a secant-secant scenario, and in this case, the formula is:
CD(CD+X)=CB(CB+AB)
Plug the values in.
AB=42
BC=18
CD=4
4(4+x)=18(18+42)
Solve for x.
16+4x=1080
4x=1064
x=266
Your answer is C
