2. Use Structure Which property of operations could you use to write an equivalent expression for y + 1/2 Write the equivalent expression. ​

The triangles are similar. what is the value of x? show your work.

What is the equation of a line passing through the point (6,1) and parallel to the line whose equation 3x=2y+4

(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.)
