3. A rocket is launched from atop a 56-loot chill with an initial velocity of 135 Ius Substitute the values into the vertical motion formula
- How long will the rocket will take to hit the ground alter it is launched Round to the nearest tenth ol a second
0--1622+56t+135; 0.4 s
b. 0--166256t+135; 8.8 s
e. 0=-1662 +135t+56; 0.4 s
d. 0--1612+135t+56; 8.8 s

(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.)
