Answer:
Step-by-step explanation:
Given :
From rules of probability :
........................... equation *
can be written as x
Also , can be written as x
substituting into equation * , we have
since P(B) = 0.7, then
so , substituting each values , we have
Subtract 3 on both sides.
Add x....
<h2>BONUS!!</h2>
Multiply by 3
Divide by 4
1.11
Let x be the number of employees in 2011. The number of employees in 2012 was 105% of x, i.e.
The number of employees in 2013 was 105% of the number of employees in 2012, i.e.
Since 11025/10000 = 110.25%, there was an increment of 10.25%
The two labeled angles are "vertical angles".
Vertical angles are equal.
So ...
14x + 8 = 15x
I'm sure you can handle it now.
