The classified label for the test data (0,0,0) depends on the value of K. Please provide the value of K to determine the specific classified label.

To classify the test data (0,0,0) using the K-nearest neighbors (KNN) algorithm, we need to calculate the distance between the test data and each point in the training dataset. Then, we select the K nearest neighbors based on the distance metric and assign the majority class label among those neighbors as the predicted label for the test data.

Let's calculate the Euclidean distance between the test data (0,0,0) and each point in the training dataset:

Distance to Class A: sqrt((0-0)^2 + (0-1)^2 + (0-0)^2) = 1

Distance to Class B: sqrt((0-1)^2 + (0-2)^2 + (0-2)^2) = sqrt(5)

Distance to Class C: sqrt((0+1)^2 + (0+1)^2 + (0+1)^2) = sqrt(3)

Now, based on the value of K, we select the K nearest neighbors. Let's assume K=3 for illustration purposes. Among the distances calculated above, the three closest points are from Class A, Class C, and Class C. Therefore, if K=3, the majority class among these three neighbors is Class C, so the classified label for the test data (0,0,0) would be Class C.

The classified label for the test data (0,0,0) when using the K-nearest neighbors (KNN) algorithm depends on the value of K. To determine the specific classified label, please provide the desired value of K.

The number of engines that must be made to minimize the unit cost are 180

From the question, we have the following parameters that can be used in our computation:

C(x) = −0.5x² + 180x + 25,609.

Differentiate the above equation

So, we have the following representation

C'(x) = -x + 180

Set the equation to 0

So, we have the following representation

-x + 180 = 0

This gives

x = 180

Substitute x = 180 in the above equation, so, we have the following representation

C(180) = −0.5(180)² + 180(180) + 25,609

Evaluate

C(180) = 41809

Hence, the engines that must be made to minimize the unit cost are 180

Check the picture below.

The true statement is " The snow accumulates faster by 2 inches per hour at Snow Mountain Resort than at Windy Slopes Resort." (option b).

For Snow Mountain Resort, the slope of the line representing snow accumulation is 0.5 inches per hour. This means that for every hour that it snows, the snow depth increases by 0.5 inches.

For Windly Slopes Resort, the equation given is s = 1/4h + 6. We can rewrite this equation in the form

y = mx + b,

where y is the snow depth, x is the time in hours, m is the slope, and b is the y-intercept.

By rearranging the equation, we get

y = 1/4x + 6,

which means that the slope of the line representing snow accumulation is 1/4 inch per hour.

Now we can compare the slopes of the two lines to determine which resort has a faster snow accumulation rate.

Comparing the slopes of the two lines, we can see that the slope for Snow Mountain Resort (0.5 inches per hour) is greater than the slope for Windly Slopes Resort (0.25 inches per hour). This means that the snow accumulates faster at Snow Mountain Resort than at Windly Slopes Resort.

Therefore, the correct answer is (b) The snow accumulates faster by 2 inches per hour at Snow Mountain Resort than at Windy Slopes Resort.

Using these traces, we can sketch the surface as an ellipsoid in three dimensions centered at the origin, with semi-major axis of length 6 along the z-axis, semi-major axis of length 3 along the y-axis, and semi-major axis of length 2 along the x-axis.

To sketch the surface 9x^2 + 4y^2 + z^2 = 36 using traces, we can fix values of x, y, and z and plot the resulting curves. When we fix x = 0, we get 4y^2 + z^2 = 36, which is an ellipse in the yz-plane centered at the origin with semi-major axis of length 6 along the z-axis and semi-minor axis of length 3 along the y-axis.

When we fix y = 0, we get 9x^2 + z^2 = 36, which is also an ellipse in the xz-plane centered at the origin with semi-major axis of length 6 along the z-axis and semi-minor axis of length 2 along the x-axis. When we fix z = 0, we get 9x^2 + 4y^2 = 36, which is a horizontal ellipse in the xy-plane centered at the origin with semi-major axis of length 2 along the x-axis and semi-minor axis of length 3 along the y-axis.

Answer:

(1, 2)

Step-by-step explanation:

Given the equation of the lines x + 2y = 5 and 2x - 3y = -4

First we need to make x the subject of the formulas

For x+2y = 5

x = 5 - 2y ... 1

For 2x - 3y = -4

2x = -4+3y

x = (-4+3y)/2 ... 2

Equate 1 and 2

5 - 2y =  (-4+3y)/2

2(5-2y) = -4+3y

10 - 4y = -4+3y

-4 -3y = -4-10

-7y = -14

y = 14/7

y = 2

Substitute y = 2 into 1

x = 5 = 2y

x = 5 - 2(2)

x = 5 - 4

x = 1

Hence the point where the lines meet will be at (1, 2)

suppose that x is a normal random variable with a mean of 5. if p{x > 9} = .2, So, the approximate variance of the normal random variable X is 22.66.

To find the variance of a normal random variable X with mean 5 and given P(X > 9) = 0.2, we will follow these steps:

1. Recognize that X follows a normal distribution: X ~ N(μ, σ²), where μ = 5 and σ² is the variance we want to find.

2. Convert the probability statement P(X > 9) = 0.2 to a standard normal distribution (Z) by finding the corresponding Z-score:
  Z = (X - μ) / σ

3. Look up the Z-score that corresponds to the given probability (0.2) in a standard normal (Z) table. Since the table typically gives P(Z < z), we'll find P(Z < z) = 1 - 0.2 = 0.8. The corresponding Z-score is approximately 0.84.

4. Plug in the known values and solve for σ:
  0.84 = (9 - 5) / σ
  σ ≈ 4 / 0.84
  σ ≈ 4.76

5. Finally, find the variance, which is σ²:
  σ² ≈ 4.76²
  σ² ≈ 22.66

So, the approximate variance of the normal random variable X is 22.66.

The approximate variance of the normal random variable X is the square of the standard deviation:

Var(X) ≈ \((4.76)^2\) ≈ 22.65 (rounded to two decimal places).

To approximate the variance of the normal random variable X with a mean of 5, given that P(X > 9) = 0.2, we can use the z-score and standard normal distribution.

First, we calculate the z-score using the standard normal distribution formula:

z = (X - μ) / σ

where X is the value of interest (in this case, 9), μ is the mean (5), and σ is the standard deviation.

Plugging in the values, we get:

z = (9 - 5) / σ = 4 / σ

Next, we use the standard normal distribution table or a calculator to find the z-score that corresponds to a cumulative probability of 0.2. Let's assume that z = -0.84.

Now, we can use the z-score formula to solve for the standard deviation σ:

-0.84 = 4 / σ

Cross-multiplying, we get:

-0.84σ = 4

Dividing both sides by -0.84, we get:

σ ≈ 4 / -0.84 ≈ -4.76

Since the standard deviation cannot be negative, we discard the negative value and take the absolute value, resulting in:

σ ≈ 4.76
