Name a point that is coplanar

The required value of cos( θ ) = 3/5 in the shown figure which is the correct option would be an option (A).

To convert from Polar Coordinates (r,θ) to Cartesian Coordinates (x,y) :

x = r × cos( θ )  ....(i)

y = r × sin( θ )  ....(ii)

As per the given question, we have

x = 0.6 and r = 1

Substitute the values of x = 0.6 and r = 1 in the equation (i), and solve for cos( θ )

0.6 = 1 × cos( θ )

0.6 = cos( θ )

cos( θ ) = 0.6

cos( θ ) = 6/10

cos( θ ) = 3/5

Therefore, the required value of cos( θ ) = 3/5.

we can calculate the test statistic as follows:

t = (mean A - mean B) / √((sA² / nA) + (sB² / nB))

What is probability?

Probability is a measure or quantification of the likelihood of an event occurring. It is a numerical value assigned to an event, indicating the degree of uncertainty or chance associated with that event. Probability is commonly expressed as a number between 0 and 1, where 0 represents an impossible event, 1 represents a certain event, and values in between indicate varying degrees of likelihood.

To determine if the data suggests that the two methods provide the same mean value for natural vibration frequency, we can perform a hypothesis test.

Let's define the hypotheses:

H0: The mean value for natural vibration frequency using Method A is equal to the mean value using Method B.

H1: The mean value for natural vibration frequency using Method A is not equal to the mean value using Method B.

We can use a two-sample t-test to compare the means. We calculate the test statistic and the p-value to make our decision.

If we have the sample means, standard deviations, and sample sizes for both methods, we can calculate the test statistic as follows:

t = (mean A - mean B) / √((sA² / nA) + (sB² / nB))

Here, mean A and mean B are the sample means, sA and sB are the sample standard deviations, and nA and nB are the sample sizes for Methods A and B, respectively.

The p-value corresponds to the probability of observing a test statistic as extreme as the one calculated, assuming the null hypothesis is true.

To find the interval for the p-value, we need more information such as the sample means, standard deviations, and sample sizes for both methods. With that information, we can perform the calculations and determine the p-value interval.

Hence, we can calculate the test statistic as follows:

t = (mean A - mean B) / √((sA² / nA) + (sB² / nB))

Step-by-step explanation:

According to the question we get the following outputs For x = 0, g(0) = 0 , For x = 2, g(2) = 4 , For x = 4, g(4) = 8. the range of the function g(x) = 2x, with the given domain {0, 2, 4}, is {0, 4, 8}.

The range of the function g(x) = 2x, with the given domain {0, 2, 4}, can be determined by evaluating the function for each value in the domain.

For x = 0: g(0) = 2(0) = 0

For x = 2: g(2) = 2(2) = 4

For x = 4: g(4) = 2(4) = 8

Therefore, the range of the function is {0, 4, 8}.

Lorenz curve is a graph that measures the income distribution of a nation. It demonstrates how much of the total income is received by the poor or rich people of the nation. The Gini coefficient for state A is 0.222.

Lorenz curve is a graph that measures the income distribution of a nation. It demonstrates how much of the total income is received by the poor or rich people of the nation.

The graph measures how fair the distribution of wealth is in a country. In the given problem, Jonathan is analyzing the income of individuals in state A.

The Lorenz curve equation for state A is given as: L = (4/9)Q(Q-1)^2Where,L is the cumulative proportion of the population Q is the cumulative proportion of the total income Let's calculate the Gini coefficient.

The formula for Gini coefficient is given as: G = (A)/(A+B)Where, A is the area between the Lorenz curve and the line of perfect equality B is the area under the line of perfect equality For calculating the value of A, we will integrate the Lorenz curve equation.

As we can see, the Lorenz curve equation is given in terms of Q and L. We need to convert it into Q and 1 - L as we cannot integrate it in its current form. Q = (9/16)(1-L)^(1/2) + 1/2On substituting this value of Q into the Lorenz curve equation, we get: L = (9/16)(1-L)(1-(9/16)(1-L))^(1/2) + 1/2Let's solve this equation for L and we get: L = 0.7142We can now plot this value of L on the Lorenz curve.

The graph will have the point (0,0), (1,1), and (0.7142,0.4) using which we can calculate the area A. Let's calculate the area of A using the following formula: Area of A = (1/2) x 0.7142 x 0.4 = 0.143Let's now calculate the value of B. As we know, the area under the line of perfect equality is equal to 0.5.

Therefore, the value of B is 0.5.Let's now use the formula for the Gini coefficient and substitute the values of A and B:G = 0.143 / (0.143 + 0.5) = 0.222Therefore, the Gini coefficient for state A is 0.222.
