Answer:

f(-2) = 2

Step-by-step explanation:

f(-2) is equal to x = -2.

When x = -2, y = 2

Therefore, f(-2) = 2

(a) The value of k for which the matrix B is singular is k = -2.

(b) When λ = 2 is an eigenvalue of B, the value of k is not uniquely determined.

(a) To determine the value of k for which the matrix B is singular, we need to find when the determinant of B is equal to zero. The determinant of B is given by:

[tex]|B| = (k)((k)(9) - (-11)(0)) - (0)((-11)(9) - (k)(-11)) + (1)((-11)(0) - (k)(-11))[/tex]

Simplifying the determinant expression and setting it equal to zero, we get:

[tex](k)(9k + 11k) + (11)(-11) = 020k^2 - 121 = 0[/tex]

Solving this quadratic equation, we find two possible values for k: k = -11/4 and k = 11/4. However, for B to be singular, the determinant must be zero, which means the value of k is k = -11/4.

(b) To determine the value of k when λ = 2 is an eigenvalue of B, we need to find the values of k that satisfy the equation Bv = λv, where v is the eigenvector corresponding to λ. Substituting the given values, we have:

Bv = 2v

Expanding the equation, we get:

[tex](k)(v1) + (0)(v2) + (1)(v3) = 2v1\\(-11)(v1) + (k)(v2) + (0)(v3) = 2v2\\(0)(v1) + (-11)(v2) + (k)(v3) = 2v3[/tex]

Simplifying these equations, we find that there are multiple solutions for k that satisfy the given conditions. The value of k on this occasion is not uniquely determined.

Answer: 71.429 miles

Step-by-step explanation:

The charge for the rental truck can be represented by the equation: y= 0.28m+80

m is the miles driven

y is the total cost

Plug in 100 for y because that’s how much you have to spend

100=0.28m+80

-80 -80

20=0.28m. Divide both sides by 0.28

71.429 miles

Answer:

10.0625 pounds exactly. I'm assuming that's what this question is asking, or 161 ounces.

Step-by-step explanation:

First, multiply 7 by 23, we get 161 ounces. Assuming the question is asking for pounds, and then we divide by 16. As there are 16 ounces in a pound. 161/16 = 10.0625.

Not sure the rounding so this is the number you get from a calculator exactly.

Given the values a = 0, b = 0, and c = a + b, we are asked to find the values of expressions involving these variables: C = 2017(b + c), D = 2018, and E = 2019.

Given a = 0 and b = 0, we can substitute these values into the expressions involving c.

Since c = a + b, we have c = 0 + 0, which simplifies to c = 0.

Now we can evaluate the expressions:

A) 2015: No information is provided to determine the value of 2015. We cannot evaluate this equation.

B) 2016: Similarly, no information is provided to determine the value of 2016. We cannot evaluate this expression.

C) 2017(b + c): Substituting c = 0, we have C = 2017(b + 0) = 2017b.

D) 2018: This expression has a constant value of 2018.

E) 2019: This expression has a constant value of 2019.

In summary, the values of the expressions are as follows: C = 2017b, D = 2018, and E = 2019. The values of A and B cannot be determined without additional information.

Answer:

Step-by-step explanation:

We can start by simplifying the left side of the equation using the product of powers rule, which states that when we multiply two powers with the same base, we can add their exponents.

6^9 * 6^x = 6^2

Now we can use the rule to add the exponents on the left side of the equation:

6^(9+x) = 6^2

Since the bases are the same, we can equate the exponents:

9 + x = 2

Subtracting 9 from both sides gives us:

x = -7

Therefore, the value of x in the product of powers equation is -7.

Answer: .47

Step-by-step explanation:

For a standardized normal distribution, Z, the probability that Z is greater than 1.50 is less than the probability that Z is greater than 2.50. False, is the correct statement regarding the given statement.

In statistics, the standardized normal distribution is a normal distribution with a mean of zero and a standard deviation of one. It is also known as the standard normal distribution. The distribution is entirely defined by its mean and standard deviation. For example, any normal distribution can be standardized by subtracting its mean and dividing by its standard deviation.This distribution is a continuous probability distribution.

A continuous probability distribution is a probability distribution that assigns probabilities to an infinite number of possible outcomes that are not countable. These probabilities are expressed as the area under the curve in a continuous probability distribution. The total area under the curve of a continuous probability distribution is always equal to one.

The statement given "For a standardized normal distribution, Z, the probability that Z is greater than 1.50 is less than the probability that Z is greater than 2.50" is false.

This is because the normal distribution curve is a symmetrical curve and the probability of being greater than a value of 1.50 or 2.50 is the same.

Therefore, the probability of Z being greater than 1.50 is the same as the probability of Z being greater than 2.50. The answer is False.

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.

Answer:

m∠MKN = 61°

Step-by-step explanation:

Since KN is a perpendicular bisector, m∠NKM and m∠MKJ have to add up to 90°.

Step 1: Set up equation

6x + 7 + 3x + 2 = 90

Step 2: Solve for x

Step 3: Find m∠MKN

m∠MKN = 6x + 7

m∠MKN = 6(9) + 7

m∠MKN = 54 + 7

m∠MKN = 61°

Answer:

61

Step-by-step explanation:

Since JKL is a straight line, it equals 180

JKM + MKN + NKL = 180

3x+2 + 6x+7 + 90 = 180

Combine like terms

9x+99 = 180

Subtract 99 from each side

9x+99-99= 180-99

9x =81

Divide each side by 9

9x/9 = 81/9

x=9

We want MKN

6x+7 = 6*9 +7 = 54+7 = 61

Step-by-step explanation:

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).
