The Harlem Globetrotters are known for spinning basketballs on one finger. If the diameter of a basketball is 9.5 inches, what is the surface area of the globetrotters must work with? Round to the nearest tenth. 30 points please show your work thank you so so so much

Given the sequence 7, 14, 28, 56, which expression shown would give the tenth term? a. 7^10 b. 7·2^10 c. 7·2^9

(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.)

Measure a and b and find their sum. how are the angles related?
