Let's imagine that we turn the machine on 100 times. (this will make the percent conversion easier)
the chance that works in the morning is 50% of 100 so it will work 50 times.
the chance that it will then continue for the rest of the day is 15% so 15%*50 (the number of times it worked), which is 7.5 times.
our times actually represented percent, so the answer is : 7.5%!
we know that
If the point belongs to the graph, then the point must satisfy the equation
we will proceed to verify each case
<u>case A.)</u> 
The point is 
Verify if the point satisfy the equation
For
find the value of y in the equation and compare with the y-coordinate of the point



therefore
the equation
not passes through the point 
<u>case B.)</u> 
The point is 
Verify if the point satisfy the equation
For
find the value of y in the equation and compare with the y-coordinate of the point



therefore
the equation
passes through the point 
<u>case C.)</u> 
The point is

<u>case D.)</u> 
The point is 
Verify if the point satisfy the equation
For

therefore
the equation
passes through the point 
therefore
<u>the answer is</u>
