Step-by-step explanation:
Given
Solving (a): Number of students
Represent students with S and non students with N
So:
--- (1)
--- (2)
Make N the subject of formula in (1)
Substitute 434 - S for N in (2)

<h2>Answer:</h2>
is 3 ohms
In a circuit containing two resistors and
connected together in parallel, the total resistance
is given by;
---------(i)
<em>Make </em><em> subject of the formula;</em>
=>
=>
=> ---------------(ii)
From the question,
= 6Ω
= 2Ω
Substitute these values into equation (ii) as follows;
=>
= 3Ω
Therefore, the value of = 3 ohms or
= 3Ω
