A jar contains 27 differently coloured balls. If you remove all the balls, one at a time, how many colour sequences are possible? D a. 27^27 O b. 27! O c. (27-1)! d. 27 O e. 1Consider the two functions x1 = y and x2 = b on the y-interval [-a, a], if a = 5.8. What value does b have to be in order for the area between x, and 2 and [-a, a], to equal 39.3? Round your answer to five decimal places. Answer:A jar contains 10 differently coloured balls. If you remove two balls, one at a time, how many different colour sequences are possible? O a. 10!/2! O b. 10!/((10 - 2)!2!) O c. 10!/(10 - 2)! O d. 10 O e. 10
