b. Is {9x - 17x2 - 20,13x2 - 8x +18,5x -9x2 -11} a basis for P2?________ Be sure you can explain and justify your answer.
c. A basis for the subspace H is {____________}. Enter a polynominal or a comma separated list of polynomials.

Answers

Answer 1

a. The dimension of the subspace H is 2. b. No, {9x - 17x^2 - 20, 13x^2 - 8x + 18, 5x - 9x^2 - 11} is not a basis for P2. c. A basis for the subspace H is {9x - 17x^2 - 20, 5x - 9x^2 - 11}.

a. To find the dimension of the subspace H, we need to determine the number of linearly independent vectors in H. In this case, H is spanned by three vectors: 9x - 17x^2 - 20, 13x^2 - 8x + 18, and 5x - 9x^2 - 11. By performing operations on these vectors, we can see that the second vector can be expressed as a linear combination of the other two vectors. Thus, the dimension of H is 2.

b. To determine if the given set of vectors is a basis for P2, we need to check if they are linearly independent and span P2. Since the dimension of P2 is 3, a basis for P2 must consist of three linearly independent vectors. However, the given set only contains two linearly independent vectors, as mentioned in part a. Therefore, {9x - 17x^2 - 20, 13x^2 - 8x + 18, 5x - 9x^2 - 11} is not a basis for P2.

c. A basis for the subspace H can be obtained by selecting the linearly independent vectors from the given set. From part b, we determined that {9x - 17x^2 - 20, 13x^2 - 8x + 18, 5x - 9x^2 - 11} is not a basis for P2. However, we can identify two linearly independent vectors within that set, which form a basis for the subspace H. Therefore, a basis for H is {9x - 17x^2 - 20, 5x - 9x^2 - 11}.

What is an angle?

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Given the angle, AOD and BOC are opposite angles.

Since opposite angles are the same

So,

∠BOC = ∠AOD

Consider the following public good provision game. Players can choose either to contribute (C) or not contribute (NC) to the public good. If someone contributes, both will be able to consume the good, which worths v dollars and is publicly known. The player i's cost to contribute is Cᵢ, which is private information. It is common knowledge that C₁,C₂ are drawn from a uniform distribution with support (Cₗ, Cₕ]. Assume v > Cₕ. C NC
C ᴠ - C₁ . ᴠ - C₂ ᴠ - C₁, ᴠ
(a) Suppose player 2 contributes if C₂ < C*₂, where C*₂ is a cutoff point. What is the expected payoff for player 1 to contribute and not contribute? What would player 1 do when C₁ is low? (b) Suppose player 1 also employ a cutoff strategy. Solve for the cutoff point (C*₁, C*₂). What is the Bayesian Nash equilibrium of the game?

Answers

In the given public good provision game, player 1's expected payoff for contributing and not contributing depends on player 2's cutoff point (C*₂). When player 1 contributes, their payoff is v - C₁ if C₁ < C*₂, and 0 if C₁ ≥ C*₂. When player 1 does not contribute, their payoff is always 0.

How does player 1's expected payoff vary based on player 2's cutoff point (C*₂)?

In this public good provision game, player 1's decision to contribute or not contribute depends on their private cost, C₁, and player 2's cutoff point, C*₂. If player 1 contributes, they incur a cost of C₁ but gain access to the public good valued at v dollars. However, if C₁ is greater than or equal to C*₂, player 1's expected payoff for contributing would be 0 since player 2 would not contribute.

On the other hand, if player 1 does not contribute, their expected payoff is always 0, as they neither incur any cost nor receive any benefit from the public good. Therefore, player 1's expected payoff for not contributing is constant, irrespective of the cutoff point.

To determine player 1's expected payoff for contributing, we consider the case when C₁ is less than C*₂. In this scenario, player 2 contributes to the public good, allowing both players to consume it. Player 1's payoff would then be v - C₁, which represents the value of the public good minus their cost of contribution. However, if C₁ is greater than or equal to C*₂, player 1's contribution would be futile, as player 2 would not contribute. In this case, player 1's expected payoff for contributing would be 0, as they would not gain access to the public good.

In summary, player 1's expected payoff for contributing is v - C₁ if C₁ < C*₂, and 0 if C₁ ≥ C*₂. On the other hand, player 1's expected payoff for not contributing is always 0. Therefore, when C₁ is low, player 1 would prefer to contribute, as long as the cost of contribution is less than player 2's cutoff point.

Two sides of a rectangle are in the ratio 3:4. If the longer side is 20 cm, what is the perimeter of the rectangle?

Answers

Answer:

The perimeter of the rectangle is 70 cm

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ Two sides of a rectangle are in the ratio 3 : 4

→ Let the width is the shorter side and the length is the longer side

∴ The ratio between the width and the length is 3 : 4

∵ The longer side is 20 cm

The length of the rectangle = 20 cm

→ By using the ratio method

→  width  :  length

→  3          :  4

→  w         :  20

→ By using cross multiplication

w × 4 = 3 × 20

∴ 4w = 60

→ Divide both sides by 4

∴ w = 15

The width of the rectangle = 15 cm

∵ The perimeter of the rectangle = 2(length + width)

∴ The perimeter of the rectangle = 2(20 + 15)

∴ The perimeter of the rectangle = 2(35)

∴ The perimeter of the rectangle = 70 cm

The perimeter of the rectangle is 70 cm

what is the minimum number of coin tosses do you have to have have such that the odds of getting a heads is more than 50%

Answers

The minimum number of coin tosses required to have more than a 50% chance of getting at least one head is two.

How do we calculate?

The possible outcomes of flipping a coin:

Heads (H)Tails (T)

If the coin is flipped more than once, there are only two possible outcomes: H or T, whereby each outcome has a 50% chance of occurring.

So let us say that the coin is flipped twice, we have four possible outcomes:

HH, HT, TH, and TT.  

In this case, the only outcome that do not have at least one head is TT.

In conclusion,  the probability of getting at least one head is 1 - (1/2 x 1/2) = 3/4, or 75% which is greater than 50%

Answers

Write a function which accepts a nested list of integers and returns the count of all the integers greater than 0. This can be done in a recursive manner by first flattening the nested list and then counting all the integers that are greater than 0.The function can be implemented using any programming language such as Python, Java, or C++.

A nested list is a list that contains other lists. It is a common data structure used in programming languages such as Python, LISP, and Scheme. The task at hand is to write a function that accepts a nested list of integers and returns the count of all the integers greater than 0. To accomplish this task, we can use a recursive approach. The first step is to flatten the nested list into a single list. This can be done by recursively iterating through the list and adding each element to a new list.

Once we have a single list, we can count all the integers that are greater than 0 using a loop or list comprehension. Finally, we return the count as the output of the function. Here is an implementation of the function in Python: def count_positive(lst): flat_list = [] for i in lst: if type(i) == list: flat_list. extend(count _ positive(i)) else: flat _ list. append(i) return len([x for x in flat_list if x > 0])The above function takes a nested list as an argument and returns the count of all the integers greater than 0.

The function first flattens the list and then counts all the integers that are greater than 0 using a list comprehension. The function can be tested using the example given in the question:>>> count_positive([[6,[-3,[1]]],[4,-1,[[0],5]]])5In the above example, there are five integers greater than 0 in the nested list. Therefore, the output of the function is 5.

Answers

7 is an outlier.

Data:

7, 58, 62, 68, 65, 86, 72, 76, 74

Let us rearrange the data

7, 58, 62, 65, 68, 72, 74, 76, 86

To know if a number is an outlier, it is usually either:

1. Lower Outlier Threshold = Less than Q1 + 1.5 x IQR

2. Higher Outlier Threshold = Greater than Q3 - 1.5 x IQR

where IQR is the interquartile range

Q1 is the First Quartile

Q3 is the Third Quartile.

Now we have to find Q1, Q3, and IQR.

The formulas are given below:

\(\begin{gathered} Q1=\frac{(1\times(n+1))}{4}^{th} \\ \text{where n is the number of values in the dataset} \\ \\ Q3=\frac{(3\times(n+1))}{4}^{th} \\ \\ \text{IQR}=Q3-Q1 \end{gathered}\)

n = 9 (according to the question)

Thus, with these formulas, we can find the Q1, Q3, and IQR

\(\begin{gathered} Q1=\frac{(1\times(9+1))^{th}}{4} \\ Q1=\frac{10}{4}^{th}=2.5^{th} \\ Q1\approx3^{rd} \end{gathered}\)

Therefore, the first Quartile Q1 is in the third position in the arranged data:

7, 58, 62, 65, 68, 72, 74, 76, 86

Q1 = 62.

Now we solve for Q3:

\(\begin{gathered} Q3=\frac{(3\times(9+1))^{th}}{4}=\frac{(3\times10)^{th}}{4}=\frac{30}{4}^{th} \\ Q3=7.5^{th}\approx8^{th} \end{gathered}\)

Therefore, the third Quartile Q3, is in the 8th position in the arranged data:

7, 58, 62, 65, 68, 72, 74, 76, 86

Q3 = 76

Now, we can calculate IQR as:

Q3 - Q1 = 76 - 62 = 14

Thus, IQR = 14

Now we can test which values are outliers.

\(\begin{gathered} LowerOutlierthreshold=Q1-1.5\times IQR \\ \text{Lower Outlier }threshold\text{ = 62- 1.5}\times14=41 \end{gathered}\)

We have a value of 7 which is much lower than the Lower Outlier threshold value.

Thus 7 is an outlier.

Now let us check for the HIgher Outlier:

\(\begin{gathered} \text{Higher Outlier threshold = Q3 + 1.5}\times IQR \\ \text{Higher Outlier threshold= 76 + 1.5}\times14 \\ \text{Higher Outlier threshold= 97} \end{gathered}\)

We have no value from the dataset that is greater than 97, thus there is no upper outlier

Therefore, the final answer is = 7

Recall that our initial condition u₀ (derived from Ohm's Law) contains only the voltage across resistor R, where voltage is supplied by the given battery. This is because the current is stopped once it reaches the inductor in the circuit since it resists change.

Back-Substitute in u and u₀:
\(\displaystyle \frac{\mathcal E}{R} - I = \frac{\mathcal E}{R} e^{- \frac{R}{L} t}\)Solve for I:
\(\displaystyle I = \frac{\mathcal E}{R} - \frac{\mathcal E}{R} e^{- \frac{R}{L}t}\)

Step 5: Solve

If we are trying to find the strength of the electrical current I at t = 0, we simply substitute t = 0 into our current function:

\(\displaystyle\begin{aligned}I(t) & = \frac{\mathcal E}{R} - \frac{\mathcal E}{R} e^{- \frac{R}{L}t} \\I(0) & = \frac{\mathcal E}{R} - \frac{\mathcal E}{R} e^{- \frac{R}{L}(0)} \\& = \boxed{\bold{0}}\end{aligned}\)

If we are taking the limit as t approaches infinity of the current function I(t), we are simply just trying to find the current after a long period of time, which then would just be steady-state equilibrium:

\(\displaystyle\begin{aligned}I(t) & = \frac{\mathcal E}{R} - \frac{\mathcal E}{R} e^{- \frac{R}{L}t} \\\lim_{t \to \infty} I(t) & = \frac{\mathcal E}{R} - \frac{\mathcal E}{R} e^{- \frac{R}{L}(\infty)} \\& = \boxed{\bold{\frac{\mathcal E}{R}}}\end{aligned}\)

∴ we have found the current I at t = 0 and the current I after a long period of time and proved that an inductor resists current running through it in the beginning and acts like a wire when in electrical equilibrium.

Given sin theta=5/13 and cos theta=12/13, which of the following can be proven using a Pythagorean identity?

Answers

Answer:

4th option

Step-by-step explanation:

given

sinΘ = \(\frac{5}{13}\) and cosΘ = \(\frac{12}{13}\) , then

( \(\frac{5}{13}\) )² + ( \(\frac{12}{13}\) )²

= \(\frac{25}{169}\) + \(\frac{144}{169}\)

= \(\frac{25+144}{169}\)

= \(\frac{169}{169}\)

= 1

showing sin²Θ + cos²Θ = 1

what is the relationship between student's t distribution and the standard normal distribution? student's t will approach to standard normal distribution as the sample size approachs 0 student's t will approach to standard normal distribution as the sample size approachs infinite standard normal distribution will approach to student's t distribution as the sample size approachs 0 standard normal distribution will approach to student's t distribution as the sample size approachs infinite

Answers

The correct relationship between Student's t-distribution and the standard normal distribution is option B: as the sample size approaches infinity, the Student's t-distribution approaches the standard normal distribution.

The sample mean's estimation of the population mean is less precise and the sample mean's distribution is more erratic when the sample size is small. Because the distribution of t-values is more skewed as a result, the student's t-distribution has thicker tails than the traditional normal distribution.

The sample mean's distribution, however, narrows as sample size increases, making it a more precise reflection of the population mean. The student's t-distribution resembles the traditional normal distribution as a result of the narrowing of the t-value distribution.

For the ordinary normal distribution to accurately approximate the student's t-distribution in practice, a sample size of 30 or more is frequently thought to be sufficient.

Answers

Answer:

m<HJF = \(56^{o}\)

Step-by-step explanation:

From the given diagram, ΔFHJ is similar to ΔFEG. So that;

m<HJF = m<EGJ

⇒ 10x + 36 = 6x + 44

10x - 6x = -36 + 44

4x = 8

x = \(\frac{8}{4}\)

x = 2

Substitute the value of x in the expression for m<HJF to have,

m<HJF = 10x + 36

           = 10(2) + 36

           = 20 + 36

m<HJF = \(56^{o}\)

The measure of angle HJF is \(56^{o}\).

The equation shown has a missing value.

-2(2x - _) + 1 = 17 - 4x

For what missing value(s), if any, does the equation have exactly one solution?

Answers

There is no value for which the missing place should be filled in order to have exactly one solution.

A Linear equation may be defined as the one which can be represented in the form ax + b = 0 where a, b are coefficients and x is the independent variable. Since the equation only has one variable that is x then the linear equation will be rightly called as linear equation in one variable. We are given the equation -2(2x - _) + 1 = 17 - 4x. We solve the equation further which results as

-4x - _ + 1 = 17 - 4x

As we can see that there is -4 in both the right-hand side as well as the left-hand side both of them gets cancelled out.

- _ +1 = 17

As we can see that there is no variable left in order to find the value so any value of missing space will not be able to give any solution.

In order to verify the accuracy of their financial accounts, companies use auditors on a regular basis to verify accounting entries. The company’s employees make erroneous entries 5% of the time. Suppose that an auditor randomly checks three entries.

a. Find the probability distribution for Y , the number of errors detected by the auditor.

b. Construct a probability histogram for p(y).

c. Find the probability that the auditor will detect more than one error.

Answers

To find the probability distribution for Y, the number of errors detected by the auditor, we can use the binomial distribution formula. The binomial distribution is used when there are only two possible outcomes, success or failure, and each trial is independent.

In this case, the probability of success (detecting an error) is 5% or 0.05, and the probability of failure (not detecting an error) is 1 - 0.05 = 0.95.

a. To find the probability distribution for Y, we can use the formula for the binomial distribution:

P(Y = y) = (nCk) * p^k * (1-p)^(n-k)

where n is the number of trials (3 in this case), k is the number of successes (errors detected), p is the probability of success (0.05), and (nCk) is the combination formula.

For y = 0:
P(Y = 0) = (3C0) * (0.05)^0 * (0.95)^(3-0) = (1) * (1) * (0.95)^3 = 0.857375

For y = 1:
P(Y = 1) = (3C1) * (0.05)^1 * (0.95)^(3-1) = (3) * (0.05) * (0.95)^2 = 0.135375

For y = 2:
P(Y = 2) = (3C2) * (0.05)^2 * (0.95)^(3-2) = (3) * (0.05)^2 * (0.95)^1 = 0.007125

For y = 3:
P(Y = 3) = (3C3) * (0.05)^3 * (0.95)^(3-3) = (1) * (0.05)^3 * (0.95)^0 = 0.000125

So the probability distribution for Y is:
Y = 0 with probability 0.857375
Y = 1 with probability 0.135375
Y = 2 with probability 0.007125
Y = 3 with probability 0.000125

b. To construct a probability histogram for p(y), you can create a bar graph where the x-axis represents the number of errors detected (Y) and the y-axis represents the probability (P(Y = y)). Each bar will have a height corresponding to the probability.

c. To find the probability that the auditor will detect more than one error, we need to calculate the sum of the probabilities for Y = 2 and Y = 3:

P(Y > 1) = P(Y = 2) + P(Y = 3) = 0.007125 + 0.000125 = 0.00725

Therefore, the probability that the auditor will detect more than one error is 0.00725.

a die is rolled and the results are 2,4,6,1,5,1,6,3,2,4,5,6,1,6,4,3,6,1,6,6,. the experimental probability for getting a 6 is close to the theoretcal probability. true or false

Answers

To determine if the experimental probability for getting a 6 is close to the theoretical probability, we need to compare the observed frequency of rolling a 6 to the expected probability based on a fair six-sided die.

In the given list of rolls, we have a total of 20 rolls. To calculate the experimental probability of rolling a 6, we count the number of times a 6 appears and divide it by the total number of rolls.

From the list, we can see that a 6 appears 6 times. Therefore, the experimental probability of rolling a 6 is:

Experimental probability = Number of 6's / Total number of rolls = 6/20 = 0.3

Now let's compare this experimental probability to the theoretical probability. In a fair six-sided die, each face has an equal chance of occurring, so the theoretical probability of rolling a 6 is 1/6 ≈ 0.1667.

Comparing the experimental probability of 0.3 to the theoretical probability of 0.1667, we can see that the experimental probability is higher than the theoretical probability for rolling a 6.

Therefore, the statement "the experimental probability for getting a 6 is close to the theoretical probability" is false. The experimental probability is higher than the theoretical probability in this case.
