A bag of potatoes and a bag of oranges weigh 30 pounds in all. The weight of the potatoes is 5 pounds less than 4 times the weight of the oranges. Let w represent the weight of the oranges. The equation that can be used to find the
value of wis (4w-5) + W=30. Which shows the first step that should be taken to verify that w, the weight of the bag of
oranges, equals 7?
o (4(7)+5)+7= 30
o (417)-7)+5 = 30
O (4(7)+5) - 7 = 30
o (417)-5)+7= 30

(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.)
