2(3x - 1) + 2(4x + 5) = 8
tigry1 [53]

Answer:

x=0

Step-by-step explanation:

2(3x - 1) + 2(4x + 5) = 8

Distribute

6x -2 +8x +10 =8

Combine like terms

14x +8 = 8

Subtract 8 from each side

14x+8-8=8-8

14x =0

Divide each side by 14

14x/14 = 0/14

x=0

At a raffle, 1500 tickets are sold for $2 each for four prizes of $500, $250, $150, and $75. You buy one ticket. What is the exp
Kisachek [45]
To find the expected value of your gain in each prize, subtract the price of the ticket from the prize:

If the prize is $500: $500 - $2 = $498
If the prize is $250:  $250 - $2 = 248
If the prize is $160: $160 - $2 = $73

But if you did not win any cash prize, you do not have any gain because
0 cash prize - $2 ticket = -$2 which is a loss
