The scatter plot below represents the distance Robin has traveled in the first 6 hours of a trip.
The linear equation representing the line is
y = 30x + 20.

Find the missing dimension! need asap! tiny square is a =3025 in ²

(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.)

Determine domain and range, largest open interval, and intervals which function is continuous.
