What is the sign of the product (−7)(−2)(−5)(1)? Positive, because the products (−7)(−2) and (−5)(1) are negative, and the product of two negative numbers is positive Positive, because the products (−7)(−2) and (−5)(1) are positive, and the product of two positive numbers is positive Negative, because the product (−7)(−2) is positive, and the product (−5)(1) is negative, and the product of a positive and a negative number is negative Negative, because the products (−7)(−2) and (−5)(1) are negative, and the product of two negative numbers is negative

Which table represents points on the graph of h(x) = 3√-x+2?

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?

(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.)
