Arace is 10 kilometer long. markers will be placed at the beginning and the end of the race course and at each 500 meter mark. how many markers are need to mark the course for the race

Apositive number a or the same number a increased by 50% and then decreased by 50% of the result?

What is always true when two whole numbers are subtracted?

(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.)
