Marc solves the equation (V)' = 5. His work is shown below. Step 1: (V)' = 5
Step 2: 27 = 5
Step 3:14 = 54
Step 4: x = 75.5.5.5
Step 5: x = 57. M. 5.5
Step 6: x = 575
1. Explain what Marc did in steps 4 and 5.
2. Why did he do this?
3. Create your own radical equation and explain how to solve it.
4. Is there an extraneous solution to your equation?
Number your responses from 1 to 4 so your instructor can tell which question you're responding to

(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.)
