A graduate school plans to increase its enrollment capacity by developing its facilities in the programs. It offers the enrollment capacity this year was 120 graduate students. Beginning next year. The school plans to triple this number every year, with a target enrollment capacity of 3240 students, which equation represents this situation and after how many years t will the graduate school be able to achieve its target moment capacity.

(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.)
