There are 12 boys and 12 girls in Trevor's math class. His teacher will randomly select one student to present a homework problem to the class. Describe two different ways that rolling a six-sided die could be used to simulate the probability that Trevor's teacher will select a boy or girl.

Find an equation of the line perpendicular to the graph.

The owner of the plant nursery where you were tells you to fill 350 ml bottles from a 30 l from a fertilizer

(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.)
