Someone please help. Madison's bicycle wheel has 28 spokes. The diameter of the wheel is 24 inches. What is the approximate arc length between each pair of spokes? Use 3.14 for π, and round to the nearest tenth

1.2 in.
1.4 in.
2.7 in.
5.6 in.

What is the expression in factored form? -x^2 + 3x + 28 a. (x-7)(x-4) b. -(x-7)(x+4) c. (x+4)(x+7) d. -(x-4)(x+7)

Which is the solution to the inequality? 2 3/52 1/15 b< 3 2/15 b> 3 2/15

(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.)
