Consider the following sequence of Python commands: import numpy x=numpy.arange (1,10) y=numpy.linspace (1,10,9) z = x + y a = x*y Complete the following statements: There are Number numbers stored in the array x. There are Number numbers stored in the array y. The statement print (x[8]) returns the number Number The statement print (y[8]) returns the number Number Number The statement print (z[0]) returns the number The statement print (a[0]) returns the number Number If one types 4*4 at a Python prompt, then the resulting output is 16 If one types 4**4 at a Python prompt, then the resulting output is Number
