Mathematics inclined week #1: easy category.

problem:
rewrite 0. as a fraction.

you must show your working out either as a screenshot or by latex.
full solutions will be posted next week, along with a new question.

Measures of the angle of r, 31 s (x+4) t (3x+9)

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.

(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.)
