Answer:
The last one.
Step-by-step explanation:
The solutions with the horizontal lines are wrong because then h(x) would be -1 and 1 respectively.
The subtlety is in the open or closed dot. x ≥ -1 means that -1 is included, which is drawn as a closed dot. x < -1 means that -1 is excluded, which is drawn as an open dot.
Hence the last graph is the correct one.

The probability of winning the lottery is 
</h3>
Step-by-step explanation:
Here, the total numbers in the jackpot = 1 to 34
Now, the number that needed to be drawn = 5
The number of ways , 5 number can be drawn from total 34 numbers :
Also, in separate draw, the correct number drawn = 1
So, the number of ways that can be done = 30 C 5 x 37
= 278,256 x 37 = 10,295,472
Now, P(win) = 
Hence, the probability of winning the lottery is

Answer:
Step-by-step explanation:
Susan started her homework at = 1:59 pm
She took time = 96 mins
Time at which she had volleyball practice = 4:00 pm
So, time between her starting of homework and starting of volleyball is given by
1:59 pm to 4:00 pm = 2 hrs and 1 mins
2 hr 1 min = 120 mins + 1 min = 121 mins
But she took 96 mins to do her homework, so
Out of 121 mins, 96 mins she took for homework
Remaining time = 121 mins - 96 mins = 25 mins
Therefore, time Susan had between finishing her homework and the beginning of volleyball practice is 25 mins
