Find the circumference of each circle from the given radius or diameter. 1. Radius = 4m, diameter = 8 m

2. Diameter = 12ft, radius = 5ft

3. Diameter =6cm, radius = 3.2 cm

4. Diameter = 7.5 m , radius = 2.8 m

5. Radius = 8yd, diameter = 13yd

What is the value of x in the following equation. -x ^3/2 = -27

(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.)
