Mr. know -it-all says the quadrilateral below is a parellelogram, but you say it is a trapezo. Who is right? Explain your thinking

Which graph represents the equation y =4x

Lines a and b are parallel. what is the value of x? -5 -10 -35 -55

(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.)
