<u>Given</u>:

Four lines are marked proportion, the length of TW can be determined by

TW=a+4+b

<u>Value of a:</u>

Let us set the proportion for the given lines.

Thus, we have;

 \frac{a}{7}=\frac{4}{5}

5a=28

 a=5.6

Thus, the value of a is 5.6

<u>Value of b:</u>

Let us set the proportion for the given lines.

Thus, we have;

 \frac{4}{5}=\frac{b}{5}

20=5b

 4=b

Thus, the value of b is 5.

<u>Length of TW:</u>

The length of TW is given by

TW=5.6+4+4

TW=13.6

Thus, the length of TW is 13.6

Consider the following game, called matching pennies, which you are playing with a friend. Each of you has a penny hidden in you
Dahasolnce [82]

Answer:

a. The two players playing the game

b. No dominant strategy

c. No equilibrium

Step-by-step explanation:

a. The players are the two people playing the game of matching pennies

The strategy of the players are to meet the conditions of them keeping the pennies by having either heads or tails

The payoff of the game are as follows;

Player A keeps the two pennies when the outcome matches

Player B keeps the two pennies when the outcome does not match

The payoff of the game are as follows;

                                                Player A

                                             Head                          Tails

Player B  Head                     1, -1                              -1, 1

               Tails                      -1   1                               1, -1

Where:

x, y

x = Player A

y = Player B

1 = Getting to keep the two pennies

-1 = Losing a penny

b. There are no best strategy because the game is one of chance whereby the result of the strategy of one player depends on the side of the penny facing up by the other player.

c. There is no equilibrium as the possible outcomes are equal hence the outcomes can be even or one sided.

Ivanshal [37]

Answer: 12 hours

Step-by-step explanation:

3 hours landscaping = $36

She still needs to make $224 to meet her requirement.

$224 divided by $19 tutoring = 11.79 hours

224÷19=11.79

Rounded to the nearest whole number: 12

This would mean Makayla worked a total of 15 hours and made $264. Which meets her requirements.
