Answer:
42.39in^3
Step-by-step explanation:
half of 3= 1.5
Which 1.5 would be our radius. (r)
V= pi(3.14) x r^2 x h (VOLUME FORMULA FOR CYLINDER)
V= (3.14) x 1.5^2 x 6
V= (3.14) x 2.25 x 6
V= 42.39in^3
We can write an equation to solve this:
Let x represent amount of Blue Jays.
2x + x = 21
We can simplify the equation:
3x = 21
Divide both sides by 3 to isolate x variable:
x = 7
Therefore, 7 Blue Jays.

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.
