Answer:
the three concepts of capital outlay are
resources
borrowed
repaid
1) len() would do the trick, but it's not a method of the String class, it's a function that returns the number of items in a container.
2)<span> A. string_var[:6:2]
3) I'd expect to see the 4th and 5th characters of the string. Strings are zero indexed. None of the choices is correct.
4) </span><span>A. The pop() function</span>
Answer:
Explanation:
I should check the volume controls on the speaker amplifier.
Answer:
Both Technicians are correct.
Explanation:
Remember that Ohm's Law its a relationship between Voltage (E), Current (I) and Resistance (R) in an electrical circuit. This relationship is defined by the following equation:

Each one of the letters could be called a variable. Now, also remember that the number of equations you have is equal to the number of variables unknown you could have.
In Ohm's Law you have 3 variables (E,I,R) and 1 equation. It means that you need to know 2 variables (Whatever 2 variables) to know the third.
Technician A says, in other words, that could calculate the Circuit current flow (I) knowing total circuit resistance (R) and total voltage (E). Note that Technician A knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:

Technician B says, in other words, that could determine the unknown resistance (R) knowing total current (I) and source voltage (E). Once again, note that Technician B knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:

It is concluded that both technicians are right.
