Answer:
d=-5
Step-by-step explanation:
5/8(16+24)=6(d-1)+1
distribute 5/8 into (16d+24) and 6 into (d-1)
10d+15=6d-6
subtract 6d on both sides
10d-6d+15=-6
combine like terms
4d+14=-6
subtract 14 on both sides
4d=-20
divide both sides by 4
d=-5
hope this helps

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.
Answer:
0.2(2 tenths) times 0.3(3 tenths) = 0.06
Step-by-step explanation:
2 times 3 equals 6.
The 6 would have a 0 before it because you are using multiplication. If you were using addition, it would be 0.5(5 tenths) since you are adding tenths.
