Answer:
x = 10
Step-by-step explanation:
9x - 40 = 3x + 20
<u>9</u><u>x</u><u> </u><u>-</u><u> </u><u>3</u><u>x</u> - 40 = <u>3x - 3x</u> + 20
6x - 40 = 20
6x <u>-</u><u> </u><u>40</u><u> </u><u>+</u><u> </u><u>40</u> = <u>20</u><u> </u><u>+</u><u> </u><u>40</u>
6x = 60
<u>6x</u><u> </u><u>/</u><u> </u><u>6</u> = <u>60</u><u> </u><u>/</u><u> </u><u>6</u>
x = 10
Now plug the x value in the equation to make the statement true that A is parallel to B.
9x - 40
<u>9</u><u>(</u><u>10</u><u>)</u> - 40
<u>90</u><u> </u><u>-</u><u> </u><u>40</u>
50
3x + 20
<u>3</u><u>(</u><u>10</u><u>)</u> + 20
<u>30</u><u> </u><u>+</u><u> </u><u>20</u>
50
Therefore, x = 10 making the statement true that A is parallel to B. Hope this helps and stay safe, happy, and healthy, thank you :) !!
10 meaning the biggest number and then subtract by 4 since it’s the lowest number and you get 6.
C is the answer! Hope this helps!
Answer:
The pay off matrix (for numbers 1-9) is shown in the attached table.
The value of the game (expected winning per play) = $9.57
The strategy for player II is to call even numbers all the time, which guarantees a winning in every game!
The strategy for player I is to call odd numbers all the time, in case player II calls odd numbers (good luck!)
Step-by-step explanation:
The pay off matrix (for numbers 1-9) is shown in the attached table.
The payoff for player II (even wins) is 775 for 9*9 = 81 possible scenarios.
Thus the value of the game is 775/81 = $9.57 (expected winnings per play)
The strategy for player II is to call even numbers all the time, which guarantees a winning in every game!
The strategy for player I is to call odd numbers all the time, in case player II calls odd numbers (good luck!)
