Evaluate 10Σi=1 (4i2 -5)

You have 138.72 in your saving account u take out 45.23 and 18.00 you deposit 75.85 into your account

(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.)

Yvaries directly as x. y =90 when x=6. find y when x=13
