To find the probability P(X > 10), where X is the random variable representing the total sum of the numbers observed on two cards randomly selected with replacement, we can calculate the probabilities of each possible outcome and sum them up.

The possible outcomes for the sum of the two numbers are:

Both cards are labeled 5: The sum is 5 + 5 = 10.

One card is labeled 5 and the other is labeled 10: The sum is 5 + 10 = 15.

Both cards are labeled 10: The sum is 10 + 10 = 20.

We are interested in the probability of getting a sum greater than 10, which is P(X > 10). In this case, only one outcome satisfies this condition, which is when the sum is 15.

Since the cards are selected with replacement, each selection is independent, and the probabilities can be multiplied together. The probability of selecting a card labeled 5 is 40/100 = 0.4, and the probability of selecting a card labeled 10 is 60/100 = 0.6.

Therefore, P(X > 10) = P(X = 15) = P(5 and 10) + P(10 and 5) = (0.4 * 0.6) + (0.6 * 0.4) = 0.24 + 0.24 = 0.48.

Hence, the probability that the sum of the numbers observed on the two cards is greater than 10 is 0.48.

The equilibrium of this game is {s1 = 1/2, s2 = 1/4} and Player 2 plays A if sA2 = 3/4 and plays B if sB2 = 1/2.

Consider the following two-player game. Si = [0, 1], for i = 1, 2. Player 2 is equally likely to be type A or type B, and the realization of her type is private information to her.

Payoffs are as follows:

u1(s1,s2)=1−[s1 −(1/2)s2]^4

uA2(s1,sA2)=100−[sA2 −s1−1/4]^2

uB2 (s1,sB2 )=100−[sB2 −s1]^2.

To find a Bayes-Nash equilibrium of this game, we need to solve this problem by backwards induction.

The equilibrium of this game is {s1 = 1/2, s2 = 1/4} and Player 2 plays A if sA2 = 3/4 and plays B if Subs = 1/2.

A Bayes-Nash equilibrium is a pair of strategies, one for each player, such that each player's strategy is optimal given the other player's strategy and her private information about the game.

This is a refinement of the Nash equilibrium that takes into account the players' information about the game.

Answer:

X^2+(13-2)x -26

x^2+13x-2x-26

x(x+13) -2(x+13)

(x+13) (x-2)

Answer:

Step-by-step explanation

A) To factorize x^2 + 11x - 26, we need to find two numbers that multiply to give -26 and add to give 11. These numbers are 13 and -2. Therefore, we can write:

x^2 + 11x - 26 = (x + 13)(x - 2)

B) To factorize x^2 -5x -24, we need to find two numbers that multiply to give -24 and add to give -5. These numbers are -8 and 3. Therefore, we can write:

x^2 -5x -24 = (x - 8)(x + 3)

C) To factorize 9x^2 + 6x - 8, we first need to factor out the common factor of 3:

9x^2 + 6x - 8 = 3(3x^2 + 2x - 8)

Now we need to find two numbers that multiply to give -24 and add to give 2. These numbers are 6 and -4. Therefore, we can write:

9x^2 + 6x - 8 = 3(3x + 4)(x - 2)

Answer: $$y=-2/3x+2$$

Explanation:  Given that we have the slope and a point on the graph we can use the point slope formula to find the equation of the line.

Answer:

Choice A

Step-by-step explanation:

First, let's simplify the equation. We get \(\frac{3^{-3}m^{6} n^{-3}}{6mn^{-2} }\) . Then, we can simplify. We now have \(\frac{3^{-3}m^{5} }{6n}\) . To get rid of the negative exponent, we multiply the top and bottom by 3^3 to get \(\frac{m^{2} }{6nx3^{3} }\). Note that the x in the denominator stands for multiplication. 3^3 = 27, so we have \(\frac{m^{5} }{6n(27)} = \frac{m^{5} }{162n}\)

Answer:

m^5/ 162 n

Step-by-step explanation:

( 3 m^-2 n) ^-3 / (6mn^-2)

We know a^ -b = 1/ a^b

1 / ( 3 m^-2 n) ^3 *(6mn^-2)

Distribute the power of 3

1 / ( 3^3 m^ -2 ^ 3 n^3) * ( 6m n^-2)

We know a^ b^ c = a^ ( b*c)

1 / ( 27 m^( -2 * 3) n^3) * ( 6m n^-2)

1 / ( 27 m^( -6) n^3) * ( 6m n^-2)

We know a^b * a^c = a^ ( b+c)

1 / ( 27*6 m^( -6+1) n^(3-2))

1/ (162 m^ -5 n^1)

We know a^ -b = 1/ a^b

Answer:

Skew (option d).

Step-by-step explanation:

Skew lines are the lines that do not intersect with each other. These lines exist in different planes and hence do not intersect each other and they are also not parallel. For skew lines to exist,  3 -d planes are required.

Here, the lines e and c are skew lines because they do not intersect each other and are lying on different panes. They are also skew line because the planes are co-planer,

Hence, the lines e and c are skew lines.

When lines are not parallel, and they do not intersect, such lines are said to be skewed.

Line AC and RS are skew.

From the diagram, we have two planes.

Line AC is on plane x, while line RS is on plane y

Plane x and plane y are not parallel;

So lines AC and RS are not parallel.

Also, both lines are not parallel.

Using the condition of skewness stated above, we can conclude that line AC and RS are skew.

The z-score corresponding to a score that is located 20 points above the mean in a population with a standard deviation of 10 is 2. This indicates that the score is two standard deviations above the mean

To find the z-score corresponding to a score that is located 20 points above the mean, we need to subtract the mean from the score and divide the result by the standard deviation.

Given that the standard deviation (σ) is 10, and we want to find the z-score for a score located 20 points above the mean, we have:

x = μ + 20

Using the z-score formula, we can calculate the z-score:

z = (x - μ) / σ = (μ + 20 - μ) / 10 = 20 / 10 = 2

Therefore, the z-score corresponding to a score that is located 20 points above the mean in a population with a standard deviation of 10 is 2. This indicates that the score is two standard deviations above the mean.

This is because the problem will be able to be solved with multiple solutions as long as there are no specific values assigned to x. The problem will have a solution from a range of negative infinity to infinity, meaning every number or solution you can think of.

Step-by-step explanation:

Given

f(x) = 2x - 10

f^-1(x) = ?

Now

Let y = f(x)

y = 2x - 10

Interchanging the roles of x and y we get,

x = 2y - 10

x + 10 = 2y

y =(x + 10) / 2

f^-1(x) = (x + 10)/ 2

The answer is "false". The interval [1, 2] contains all the real numbers between 1 and 2 including the endpoints.

An interval notation is used for representing the continuous set of real values. This is the shortest way of writing inequalities.

Intervals are represented within the brackets such as square brackets or open brackets(parenthesis).

The given interval is [1, 2]

The given statement is - 'the interval [1, 2] contains exactly two numbers - the numbers 1 and 2'

The given statement is 'false'.

This is beacuse, an interval consists set of all the real values in between the two values given.

So, according to the definition, there are not only the end values but also many real values in between them.

Thus, the answer is "false". The interval [1, 2] consists of all the real values between 1 and 2 including 1 and 2.

The raster data model is commonly used to represent field features, but it is not suitable for representing point, line, and polygon features.

The raster data model is a grid-based representation where each cell or pixel contains a value representing a specific attribute or characteristic. It is well-suited for representing continuous spatial phenomena such as elevation, temperature, or vegetation density. Raster data is organized into a regular grid structure, with each cell having a consistent size and shape.

However, the raster data model has limitations when it comes to representing discrete features like points, lines, and polygons. Since raster data is based on a grid, it cannot precisely represent the exact shape and location of these features. Instead, they are approximated by the cells that cover their extent.

The argument presented in the statement is not valid. It is based on an incorrect premise. The original statement posits that if all things work together for good, one should not regret the occurrence of tragic events.

This statement is incorrect because the occurrence of tragic events can never be seen as a good thing, irrespective of the outcome. Therefore, the argument is unsound, and it cannot be used to prove the point that all things do not work together for good.

The occurrence of tragic events can never be seen as a good thing. While it is true that some good can come out of tragic events, such as a sense of community, unity, and strength, it does not negate the pain and suffering caused by the event.

Thus, the conclusion drawn from the argument, that all things do not work together for good, cannot be justified based on the premise presented in the statement. In conclusion, the argument presented in the statement is based on an incorrect premise and is, therefore, invalid.
