Something that will help you to know is the next formula:
<span>P(having studies given that they passed) = P(studied and pass) / P(passed)
= 0.45/ 0.5 = 0.9
</span>
With that in mind, now you can have the answer with this formula. Hope this helps
The voltage of the circuit is 8 + i . Option C
<h3>How to determine the voltage</h3>
From the information given, we have that;
E = IZ
Where;
- E is voltage
- I is current
- Z is resistance
We have that;
I = 3 + 2i
Z = 2 - i
Substitute into the formula
E = IZ
E = ( 3 + 2i) ( 2 - i)
Making the product of complex numbers we have:
E = ( 3 × 2 - i ) + ( 4i - 2i²)
E = ( 6 - 3i ) + ( 4i - 2 ( -1) )
E = ( 6 + 2) + ( 4 - 3 ) i
E = 8 + i
Thus, the voltage of the circuit is 8 + i . Option C
