Consider the array below:

x $=$ np$.$array$([0\mathrm{.}05,-90\mathrm{.}43,1\mathrm{.}78,5,6\mathrm{.}3])$

What is the element x$[3]?$ What is the approximate value of the following expression if you implement it in Python?Consider the following array:

a $=$ np$.$array$([30,101,18,190,-55])$

If I want to select the last element of this array, what is the only option below that does not return me the element $-55?$
