Question
given figure fghi and its image f'g'h'
answer the following.
enter an algebraic rule for the rotation shown and then describe the rotation in words.
the rule is (x, y)
. and the transformation is a rotation of
tell whether the figure fghi has line symmetry, rotational symmetry, both types of
symmetry, or no symmetry. if the figure has line symmetry, record the number. if the figure
has rotational symmetry, list the angles of rotation that are less than 360°

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
