The ratio 2/5 to 1/3 has a unit rate if 2/15

(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.)

Idon't get undoing if its pass adding and subtracting so can someone ? x-2 over 5 = 18

What is the slope of any line parallel to the line 8x+9y=3 in the standard (x, y) coordinate plane?
