Hard question: there are many partially mixed strategy Nash equilibria here. Try to think of when players are indifferent between their strategies. In each of the following games, find all the pure and mixed strategy Nash equilibria. Golden Balls Player 2 Split Player 1 Split 50,50 Steal 100,0 Steal 0,100 0,0
in the Golden Balls game, there is only one pure strategy Nash equilibrium, which is (Split, Split).
In the Golden Balls game, there are two players, Player 1 and Player 2. Each player can choose to either "Split" or "Steal." The payoffs for each possible combination of actions are as follows:
If both players choose Split, they both receive a payoff of 50.
If Player 1 chooses Steal and Player 2 chooses Split, Player 1 receives 100, and Player 2 receives 0.
If Player 1 chooses Split and Player 2 chooses Steal, Player 1 receives 0, and Player 2 receives 100.
If both players choose Steal, they both receive a payoff of 0.
To find all the pure strategy Nash equilibria, we need to identify any strategies where neither player has an incentive to deviate unilaterally.
Pure Strategy Nash Equilibria:
(Split, Split): This is a pure strategy Nash equilibrium because if both players choose Split, neither player can improve their payoff by unilaterally changing their strategy to Steal.
Now let's consider mixed strategy Nash equilibria, where players randomize between their available strategies.
Mixed Strategy Nash Equilibrium:
To find the mixed strategy Nash equilibrium, we need to examine whether there exists a probability distribution over strategies that maximizes the expected payoff for each player, given the other player's strategy.
In this case, there is no mixed strategy Nash equilibrium since Player 2's expected payoff from choosing Split is always lower than the expected payoff from choosing Steal, regardless of the probabilities assigned to each strategy by Player 1. Similarly, Player 1's expected payoff from choosing Split is always lower than the expected payoff from choosing Steal, regardless of the probabilities assigned to each strategy by Player 2.
Therefore, in the Golden Balls game, there is only one pure strategy Nash equilibrium, which is (Split, Split).

Guys please, I can't go to sleep until I finish this :(
A) Identify two points on the line and write the coordinate pairs below.
B) Use your two points to find the slope, and make sure to show your work.
C) Use your slope from Part B and find the equation of the line in point-slope form. Show your work and work through the steps to transform the equation from the point-slope form into the slope-intercept form.
D) Based on the equation you found in Part C, predict how long it takes Mr. Waxman to deliver his packages on Day 0. Approximately how much did his delivery time decrease per day?
Answer:
point a- (7,7)
point b- (4,19)
slope- m=-12/3=-4/1=-4
equation of line- y=4x+35
time - 48min on day 0, and it increases by 12min a day
Step-by-step explanation:
Answer:
(4,19) (7,7)
Slope = -4
Y=-4x+35 (This is point slope intercept form, sorry but could you please convert this?)
35 minutes, 4 minutes a day
Step-by-step explanation:
You take the coordinates you see for A, in this case, the last 2
The slope you find with the equation y2-y1/x2-x1, so substitute 7-19/7-4 = -12/3=-4.
As for this, (please convert I'll find out later but you need this answer now so....)
For 35 minutes, if you know your y intercept is 35, then it will be (0,35) for 5 minutes. Also, the slope is -4, so you know that it decreases by 4 minutes.
An ice cream cone measures 4 in across the opening of the cone. Two hemisphere shaped scoops of ice cream, which have diameters of 4in, are placed on top of the cone. As the ice cream melts, it begins to fill the ice cream cone. How deep must the cone be so that the melted ice cream will fill the cone exactly to the top without overflowing?
Answer:
8 inches
Step-by-step explanation:
The volume of a hemisphere is half the volume of a sphere.
Therefore, the sum of the volumes of the two hemisphere-shaped scoops of ice cream (with diameters of 4 inches), is equal to the volume of a sphere with diameter of 4 inches.
If the melted ice cream fills the cone exactly to the top without overflowing, the volume of the cone with diameter of 4 inches must be equal to the volume of a sphere with diameter of 4 inches.
As the diameter of a circle is twice its radius, then the radius of the sphere and cone is r = 2 inches.
The formulas for the volume of a cone and the volume of a sphere are:
[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cone}\\\\$V=\dfrac{1}{3} \pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex] [tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a sphere}\\\\$V=\dfrac{4}{3} \pi r^3$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius.\\\\\end{minipage}}[/tex]
The depth of the cone is its height.
Therefore, to calculate how deep the cone must be so that the melted ice cream will fill the cone exactly to the top without overflowing, set the two equations equal to each other, substitute r = 2, and solve for h (the depth of the cone).
[tex]\begin{aligned}\textsf{Volume of a cone}&=\textsf{Volume of a sphere}\\\\\dfrac{1}{3} \pi (2)^2 h & = \dfrac{4}{3} \pi (2)^3\\\\\dfrac{1}{3} \pi \cdot 4 h & = \dfrac{4}{3} \pi \cdot 8\\\\\dfrac{4}{3} \pi h& = \dfrac{32}{3} \pi \\\\\dfrac{4}{3} h& = \dfrac{32}{3} \\\\4 h& = 32 \\\\h&=\dfrac{32}{4}\\\\h&=8\; \sf inches\end{aligned}[/tex]
Therefore, the depth of the cone must be 8 inches.
The cone must be at least 8 inches deep in order for the melted ice cream to fill the cone exactly to the top without overflowing.
1. The opening of the ice cream cone has a diameter of 4 inches. This means that the radius of the cone's opening is 4/2 = 2 inches.
2. The two hemisphere-shaped scoops of ice cream have diameters of 4 inches each. This means that the radius of each scoop is 4/2 = 2 inches.
3. When the ice cream melts, it will take up the space between the scoops and fill the cone. In order for the melted ice cream to fill the cone exactly to the top without overflowing, the depth of the cone must be equal to the combined height of the two ice cream scoops.
4. The height of each hemisphere-shaped scoop can be calculated using the formula for the volume of a sphere, which is (4/3)πr³, where r is the radius.
- For each scoop, the radius is 2 inches, so the height of each scoop is (4/3)π(2)³ = (4/3)π(8) = (32/3)π.
5. Since there are two scoops, the combined height of the two scoops is 2 * (32/3)π = (64/3)π.
6. Therefore, the cone must be at least (64/3)π inches deep in order for the melted ice cream to fill the cone exactly to the top without overflowing. This is approximately equal to 67.03 inches.

If you liked my answer, a brainliest would much be appreciated! Thanks!
The value of 2,000 is decreased to 100. Then the percentage of decrease will be 95%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The value of 2,000 is decreased to 100. Then the percentage of decrease will be given as,
P = [(2,000 - 100) / 2,000] x 100
Simplify the expression, then we have
P = [(2,000 - 100) / 2,000] x 100
P = [1,900 / 2,000] x 100
P = 0.95 x 100
P = 95%
The value of 2,000 is decreased to 100. Then the percentage of decrease will be 95%.

Anthony bought a rug for his office. He made a scale drawing of the office using a scale of 1 in = 4 ft.
What is the area of the office floor not covered by the rug?
Answer:
Area of the floor not covered = 240ft²
Step-by-step explanation:
Find the diagram attached
The area of the floor not covered = area of the office floor - area of the rug covered
Area of the office floor = 7in×5in = 35in²
Area of the rug = 5in×4in = 20in²
Area of the floor not covered = 35in²-20in² = 15in²
Since 1in = 4ft
1in² = 16ft²
Given the area of the floor not covered to be 15in²
In square feet will be 16×15 = 240ft²

Step-by-step explanation:
3 less then 5 time a number (n)
first of all we know were subtracting

in my mind the one thing that makes sense is
5n - 3
but the problem can be switched
-3 + 5n
[tex]\boxed{5n-3}[/tex]
Answer: To interpret this expression, we first identify that "3 less than 5" means that we are subtracting 3 from 5. Our equation looks like this:
5 - 3
Now, we add the variable. We would put n in front of 5, because the problem says "5 times a number n." It now looks like:
