Answer:

Step-by-step explanation:

x² - 17x + 72 = 0

Sum = -17

Product  = 72

Factor = 8 , 9

x² - 17x + 72 = 0

x² - 8x -9x + (-8)*(-9) = 0

x(x - 8) -9(x -8) = 0

(x - 8 ) (x - 9) = 0

Length = (x - 8) units

Width = (x - 9) units

Consider the following game. There is a bottle with 20 colored chips inside. There are 2 blue chips, 4 purple chips, 7 green chi
vekshin1

Answer: Expected value of playing the game is $0.

Step-by-step explanation:

Since we have given that

Total number of colored chips = 20

Number of blue chips = 2

Number of purple chips = 4

Number of green chips = 7

Number of red chips = 7

Amount of prize he gets for blue chip = $10

Amount of prize he gets for a purple chip = $5

No amount is given for red or green

Amount he had to pay = $2

So, Expected value of playing the game is given by

\frac{2}{20}\times 10+\frac{4}{20}\times 5+7\times 0+7\times 0-2\\\\=1+1-2\\\\=2-2\\\\=\$0

Hence, Expected value of playing the game is $0.
