15. in the diagram, gh bisects zfgi.
a) solve for x and find the mzfgh.
b) find mzhgi.
c) find mzfgi.
(3x - 3) -
(4x - 14)
-3) + jux-14)

"bisect" means: angle FGH = angle HGI

(3x-3)=(4x-14)

-3+14=4x-3x

x=11

Angle FGH = (3x-3) = 30

Angle HGI = Angle FGH = 30

Angle FGI = 60

Step-by-step explanation:

The fitted model gave the predicted value $2.136 with standard error $0.013. Express the prediction as an interval. (The degrees of freedom were large for this analysis, so use 100 as the df to determine t*.)

(b) The actual price for the period in question was $2.13. The judge decided that the analysis provided evidence that the price was not artificially depressed, and the opinion was sustained by the court of appeals. Write a short summary of the results of the analysis that relate to the decision and explain why you agree or disagree with it.
