Please help me I’ve been sick for a week and when I came back my teacher gives me this?! I don’t know what I’m doing.

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?

What is coefficient of the term of degree of degree 5 in the polynomial below

(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.)
