Since you are already given the formula for your arithmetic sequence you only gotta plug stuff in, and you have the following
Answer:
Option C.
Step-by-step explanation:
In the given data minimum value is 0.5 and maximum value is 6.5.
In option A and D, last interval is 4-6. It means 6.5 is not included in these histograms. So, option A and D are incorrect.
Now,
Class interval Students Number of students
0-3 B,C,D,F,G,J,K,L,M,N,O 11
3-6 E,H,I 3
6-9 A 1
Histogram plots number of hours spent listening to music daily on x axis and number of students on y axis. Height of the bar in the x interval 0 to 3 is 11, height of the bar in the x interval 3 to 6 is 3, and the height of the bar in the x interval 6 to 9 is 1.
Therefore, the correct option is C.
Answer:
Expected value of raffle = $-0.67
Step-by-step explanation:
Number of tickets sold = 5,000
Selling price of each ticket = $1
1 prize = $500
3 prizes = $300
5 prize = $30
20 prizes = $5
The value of each ticket is given by
value = $500*(1/5000) + $300*(3/5000) + $30*(5/5000 + $5*(20/5000)
value = $0.1 + $0.18 + $0.03 + $0.02
value = $0.33
The expected value is
Expected value = value - selling price
Expected value = $0.33 - $1
Expected value = -$0.67
Therefore, the expected value of this raffle is -$0.67 if you buy 1 ticket.
The negative sign means that you are most likely to lose $0.67 if you buy a raffle ticket for $1.
