Step-by-step explanation:
The solution is where both graph cross each other.
Is the solution, the point (x, y) that they gave you, the same point as where the two graph cross each other?
If yes then the solution is correct.
If no then the solution is wrong.
Answer:
Step-by-step explanation:
Given
Required
Find P(A) and P(B)
We have that:
--- (1)
and
--- (2)
The equations become:
--- (1)
Collect like terms
Make P(A) the subject
--- (2)
Substitute:
Open bracket
Represent P(B) with x
Rewrite as:
Expand
Factorize:
Factor out x - 0.45
Split
Solve for x
Recall that:
So, we have:
Recall that:
So, we have:
Since:
Then:
