What are the Nash equilibria in this game?
Both (P1=Shot, P2=Shot) and (P1=No shot, P2=No shot)
Only (P1=Shot, P2=No shot)
Both (P1=Shot, P2=No shot) and (P1=No shot, P2=shot)
the Nash equilibrium is not necessarily the best or most desirable outcome for the players involved. It simply represents a stable state where no player has an incentive to unilaterally deviate from their chosen strategy.
To determine the Nash equilibria in a game, we need to analyze the strategies of each player and identify the combinations of strategies where no player has an incentive to unilaterally deviate.
Given the options:
1. (P1=Shot, P2=Shot)
2. (P1=No shot, P2=No shot)
3. (P1=Shot, P2=No shot)
4. (P1=No shot, P2=Shot)
Let's analyze each combination:
1. (P1=Shot, P2=Shot):
If both players choose to shoot, they both face the risk of being shot and getting injured. Neither player has an incentive to deviate from this strategy, as changing to "No shot" would expose them to the risk of being shot without being able to retaliate. Therefore, (P1=Shot, P2=Shot) is a Nash equilibrium.
2. (P1=No shot, P2=No shot):
If both players choose not to shoot, they avoid the risk of being injured. Again, neither player has an incentive to unilaterally deviate from this strategy, as changing to "Shot" would expose them to the risk of being injured without gaining any advantage. Therefore, (P1=No shot, P2=No shot) is a Nash equilibrium.
3. (P1=Shot, P2=No shot):
If Player 1 chooses to shoot while Player 2 chooses not to shoot, Player 1 has an advantage and can potentially eliminate Player 2 without being injured. In this scenario, Player 2 may have an incentive to deviate from "No shot" and switch to "Shot" to protect themselves. Therefore, (P1=Shot, P2=No shot) is not a Nash equilibrium.
4. (P1=No shot, P2=Shot):
Similarly, if Player 1 chooses not to shoot while Player 2 chooses to shoot, Player 2 has an advantage and can potentially eliminate Player 1 without being injured. In this scenario, Player 1 may have an incentive to deviate from "No shot" and switch to "Shot" to protect themselves. Therefore, (P1=No shot, P2=Shot) is not a Nash equilibrium.
Based on the analysis, the Nash equilibria in this game are:
- (P1=Shot, P2=Shot)
- (P1=No shot, P2=No shot)

Step-by-step explanation:
Find the angle between the cable and the tower (×°), the angle of elevation (y°), and the distace from the base of the tower to where the cable is anchored (z).
The angle between the cable and the tower (×°), the angle of elevation (y°), and the distace from the base of the tower to where the cable is anchored (z) is z² = h² + c².
What is angle?Angle is a mathematical concept that describes the space between two lines or planes that intersect. It is measured in degrees, with a full circle (360°) representing one complete rotation. An angle can measure between 0° and 360°, with the angle size depending on the amount of rotation. Angles can be classified into right angles (90°), acute angles (less than 90°), and obtuse angles (greater than 90°).
The angle between the cable and the tower (x°) is equal to the angle of elevation (y°), and the distance from the base of the tower to where the cable is anchored (z) can be found using the trigonometric relationship between angles and sides of a right triangle.
Let the height of the tower be h, and the length of the cable be c.
Then, the angle x° can be found using the tangent ratio: tan x = h/c
The angle of elevation y° can be found using the sine ratio: sin y = h/c
Finally, the distance from the base of the tower to where the cable is anchored (z) can be found using the Pythagorean Theorem: z² = h² + c²

The angle between the cable and the tower x° = (90 - y), where the angle y is the angle of elevation of the cable to the top of the tower from the point which is ‘z’ units from the base of the tower.
What are trigonometric ratios?The trigonometric ratios are the different ratios of the sides of the right angle triangle. The different ratios are Sine, cosine, tan , secant , cosecant and cot. To find any third side of the right triangle formed, can be found using the pythagorean theorem which states that square of hypotenuse is equal to the sum of the squares of other two sides.
Given that the angle of elevation to the top of the tower is ‘y’
Also given the distance of the point on ground is ‘z’ units away from base of tower
Using angle sum property in ⃤ ABC, ∠x=90-y
tan y = height of tower/base of tower
\(y=tan^{-1}\)(height of tower/base of tower)
Similarly,
\(\angle x=tan^{-1}\)(height of tower/base of tower)
To find angle x we can use any trigonometric ratio, depending on the side given.

A circle has a radius of 4 feet. What is the radius of a bigger circle if the scale factor of the smaller to bigger is 4:9
Answer:
9 feets
Step-by-step explanation:
From the question, we have our scale factor as:
4:9 = 4/9
Smaller circle /Bigger circle = 4/9
A circle has a radius of 4 feet. What is the radius of a bigger circle?
Let the radius of the bigger circle = x
This is calculated as:
4/9 = 4/x
Cross Multiply
4x = 9 × 4
x = 36/4
x = 9 feet
Therefore, the radius of the bigger circle is 9 feet
Is the decibel level of a siren discrete or continuous? O A. The random variable is discrete. B. The random variable is continuous.
The correct answer is option A: The random variable is discrete. A decibel is a unit of measure used to quantify the loudness or intensity of sound.
From 0 dB (the quietest level of sound) to 140 dB (the loudest level of sound), it is measured on a logarithmic scale (the highest level of sound).
The decibel level of a siren is normally between 110 and 120 dB, which is regarded to be within or close to the threshold of human hearing.
The decibel level of a siren is measured on a logarithmic scale, making it a discrete variable. This indicates that it is measured in whole numbers rather than fractions of a decibel.
For instance, a siren's decibel level can be 110 dB, 111 dB, 112 dB, etc., but it cannot be 110.5 dB or 111.5 dB. Therefore, the decibel level of a siren is a discrete variable.

Duncle on each Daager constranne. and make sure your scape is labeled caretary and accurately.
1. Price constraint: Pc = $8
2. when Pc = $8, C ≈ 10.22, and S ≈ 40.88.
Price constraint: Pc = $9
3. when Pc = $9, C = 9.2, and S = 36.8.
Price constraint: Pc = $2
4. When Pc = $2, C ≈ 30.67, and S ≈ 122.68.
To graph Susan's consumption curve and budget constraints, we'll use the given information:
The price of a cup of coffee is denoted as Pc = $8.
The price of a spoonful of sugar is denoted as Ps = $0.25.
Susan's budget for coffee and sugar combined is $92.
Let's start by plotting the consumption curve for prices re = Sl, rc = 32, and rc = So. We'll calculate the number of cups of coffee (C) and the number of spoonfuls of sugar (S) corresponding to each price point.
Price constraint: Pc = $8
Since Susan spends exactly four spoonfuls of sugar (S) for each cup of coffee (C), we can express S in terms of C: S = 4C.
Using the budget constraint equation, we have: 8C + 0.25S = 92.
Substituting S = 4C into the equation: 8C + 0.25(4C) = 92.
Simplifying the equation: 8C + C = 92.
Combining like terms: 9C = 92.
Solving for C: C = 92 / 9, approximately 10.22.
Therefore, when Pc = $8, C ≈ 10.22, and S ≈ 40.88.
Price constraint: Pc = $9
Using the same approach, we substitute the new price into the equation.
9C + 0.25(4C) = 92.
Simplifying the equation: 9C + C = 92.
Combining like terms: 10C = 92.
Solving for C: C = 92 / 10, which is exactly 9.2.
Therefore, when Pc = $9, C = 9.2, and S = 36.8.
Price constraint: Pc = $2
Applying the same method:
2C + 0.25(4C) = 92.
Simplifying the equation: 2C + C = 92.
Combining like terms: 3C = 92.
Solving for C: C = 92 / 3, approximately 30.67.
Therefore, when Pc = $2, C ≈ 30.67, and S ≈ 122.68.
Now, we can plot these points on a graph with the number of cups of coffee (C) on the horizontal axis and the number of spoonfuls of sugar (S) on the vertical axis:
Consumption curve: Connect the three plotted points (10.22, 40.88), (9.2, 36.8), and (30.67, 122.68).
Budget constraint for Pc = $8: Plot the point (10.22, 40.88) and draw a straight line from the origin to that point.
Budget constraint for Pc = $9: Plot the point (9.2, 36.8) and draw a line from the origin to that point.
Budget constraint for Pc = $2: Plot the point (30.67, 122.68) and draw a line from the origin to that point.
