For which equation would x = 4 be a solution? 2x + 7 = 22 6x ÷ 8 = 3 8 - 3x = 20 2x + 8 = 4

The fraction 7/9 is equivalent to a percent that is greater than 100%. truefalse

(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.)

What is the solution of the equation? 35√(x+2)3+3=27
