Miranda hiked to the top of a waterfall. she wanted to know the waterfall's height, but she was unable to measure it. miranda created a proportion using the information from triangles pqs and trs to calculate the height of the waterfall.
how tall is the waterfall? (round your answer to the nearest foot.)

Which choice represents the sample space ,s for this event

Need on this one asap im almost done with this subject

(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.)
