True. The orthogonal projection of vector x onto the line determined by non-zero vector y is indeed a vector. The projection creates a new vector that lies on the line determined by y and is orthogonal (perpendicular) to y.

2. If the orthogonal projection of x onto the line determined by non-zero y is the vector, then x - is orthogonal to y: True

If the orthogonal projection of x onto the line determined by non-zero y is the vector, then the difference between x and the projection (x - projection) will be orthogonal to y. This is because the projection is the closest point on the line determined by y to x, and thus the difference vector will be perpendicular to the line.

3. For unit vector y ∈ R, the projection matrix for orthogonal projection onto the line determined by y is yy^T: True

For a unit vector y, the projection matrix P for the orthogonal projection onto the line determined by y is given by P = yy^T, where y^T is the transpose of the vector y. This matrix is used to calculate the orthogonal projection of a vector onto the line determined by y.

To obtain the prediction [tex]w_*^Tx[/tex] for a test sample x, we need to substitute [tex]w = X^[/tex]T\alpha into

a) To find the minimizer of the objective function f(w), we need to differentiate it with respect to w, set it equal to zero, and solve for w.

First, we expand the norm term:

[tex]||Xw - y||^2 = (Xw - y)^T(Xw - y) = w^TX^TXw - 2y^TXw + y^Ty[/tex]

Taking the derivative of f(w) with respect to w and setting it equal to zero, we get:

[tex]2(X^TXw - X^Ty)[/tex] + 2\lambda w = 0

Rearranging the terms, we have:

[tex]X^TXw[/tex] + \lambda Iw [tex]= X^Ty[/tex]

which implies that:

[tex](X^TX[/tex] + \lambda I)w [tex]= X^Ty[/tex]

To obtain the minimizer, we need to solve for w, which gives us:

[tex]w = (X^TX + \lambda I)^{-1}X^Ty[/tex]

To justify that [tex]X^TX[/tex] + \lambda I is invertible for lambda > 0, we can use the SVD decomposition of X:

X = U\Sigma [tex]V^T[/tex]

where U and V are orthogonal matrices and \Sigma is a diagonal matrix with the singular values of X. Then, we have:

[tex]X^TX = V\Sigma^TU^TU\Sigma V^T = V\Sigma^T\Sigma V^T[/tex]

Since \Sigma[tex]^T[/tex]\Sigma is also a diagonal matrix with non-negative entries, adding lambda I to [tex]X^TX[/tex] ensures that all eigenvalues are strictly positive, and hence the matrix is invertible.

b) Substituting [tex]X^Tu[/tex] for w in [tex]X^TXw[/tex] + \lambda Iw [tex]= X^Ty[/tex], we get:

[tex]X^TX(X^Tu)[/tex] + \lambda [tex]IX^Tu = X^Ty[/tex]

Simplifying, we get:

[tex]X^T[/tex]([tex]X^TX[/tex] + \lambda I)u =[tex]X^Ty[/tex]

Thus, we have:

[tex]u = (X^TX + \lambda I)^{-1}X^Ty[/tex]

Substituting this into [tex]X^Tu[/tex], we get:

[tex]w = X^T(X^TX + \lambda I)^{-1}X^Ty[/tex]

c) Since [tex]w = X^T[/tex] \alpha and [tex]X^T[/tex] represents a linear combination of the columns of X, we can say that w is a linear combination of the columns of X, and hence is "in the span of the data."

d) Substituting [tex]w = X^T[/tex]\alpha into the expression for a, we get:

[tex]a = \frac{1}{\lambda}(X^Ty - X^TX(X^T\alpha))[/tex]

Multiplying both sides by \lambda and rearranging, we get:

[tex]X^TX[/tex]\alpha + \lambda\alpha [tex]= X^Ty[/tex]

This can be rewritten as:

(\lambda I [tex]+ X^TX)[/tex]\alpha [tex]= X^Ty[/tex]

To obtain the expression for \alpha, we can simply solve for \alpha:

[tex]\alpha = (\lambda I + X^TX)^{-1}X^Ty[/tex]

Note that X^TX is the Gram (kernel) matrix for the standard vector dot product.

e) Substituting [tex]w = X^[/tex]T\alpha into the expression for Xw, we get:

[tex]Xw = XX^T\alpha[/tex]

Using the kernelized form of \alpha, we have:

[tex]Xw = XX^T(\lambda I + XX^T)^{-1}y[/tex]

f) To obtain the prediction [tex]w_*^Tx[/tex] for a test sample x, we need to substitute [tex]w = X^[/tex]T\alpha into

Having obtained the minimum distance between (-3, 4) and the line, we now seek to locate the precise point on that line. Achieving this requires a comprehension of the perpendicular line concept. Identifying where the line encountering the pivot point in question and intersecting the reference line perpendicularly is crucial for determining the closest point present on the line.

At present, the slope of the perpendicular line as well as its passing point (-3, 4) have been successfully determined. Employing the point-slope method we can obtain the equation representing the aforementioned perpendicular line:

-2x + 4 - 28 = 7x + 21

-9x = -49

x = 49/9

We can then use x to find y:

y = ( - 2 ( 49 / 9 ) + 4 ) / 7

y = (4 - 98 / 9 ) / 7

y = ( - 90 / 9) / 7

The problem is asking us to calculate the probability that less than 200 of 500 cell phone calls selected at random will be spam, given that First Orion estimates 45% of all cell phone calls in 2019 will be spam. To solve this problem, we can use the normal approximation to the binomial distribution.

First, we need to find the mean and standard deviation of the binomial distribution. The mean is given by:

μ = n * p

where n is the number of trials (500) and p is the probability of success (i.e., a cell phone call is spam) on a single trial (0.45):

μ = 500 * 0.45 = 225

The standard deviation is given by:

σ = sqrt(n * p * (1 - p))

σ = sqrt(500 * 0.45 * (1 - 0.45)) = 11.79

Next, we can use the normal approximation to calculate the probability that less than 200 of the 500 cell phone calls selected at random will be spam. We need to standardize the value of 200 using the mean and standard deviation of the binomial distribution:

z = (x - μ) / σ

where x is the number of successes (i.e., spam calls) we're interested in (200):

z = (200 - 225) / 11.79 = -2.12

We can use a standard normal distribution table or calculator to find the probability that a standard normal random variable is less than -2.12. This probability is approximately 0.017.

Therefore, the probability that less than 200 of the 500 cell phone calls selected at random will be spam is approximately 0.017 or 1.7%.

The mechanic worked for 5.5 hours to install the new water pump.

Let's assume the mechanic worked for "x" hours to install the water pump.

The cost of the repair work will include the cost of the water pump as well as the labor charges.

The cost of the water pump is given as $249.98.

The labor charges can be calculated by multiplying the hourly rate by the number of hours worked.

So, the labor charges will be $109 multiplied by "x" hours, which is $109x.

Adding the cost of the water pump to the labor charges will give us the total cost of the repair work.

Therefore, we can write the equation as:

$849.48 = $109x + $249.98

Simplifying the equation, we get:

$599.50 = $109x

Dividing both sides by $109, we get:

To determine the width of each class, we need to first find the range of the data set, which is the difference between the maximum value and the minimum value.

Max value = 77
Min value = 22
Range = 77 - 22 = 55

Next, we need to decide on the number of classes we want to use in the frequency table. For this data set, we can use between 5 and 8 classes.

Let's choose to use 5 classes for this example. To determine the width of each class, we divide the range by the number of classes:

Width of each class = Range/Number of classes
Width of each class = 55/5 = 11

So each class will have a width of 11.

Now we need to determine the boundaries of each class. We can start with the first class, which will start at the minimum value (22) and go up to the next multiple of the width (11), which is 33.

First class: [22 – 33]

For the second class, we start at the next value after the first class (39) and add the width (11) to get the upper bound of the second class:

Second class: (33 – 44]

We can continue this process to find the boundaries of the remaining classes.

Third class: (44 – 55]
Fourth class: (55 – 66]
Fifth class: (66 – 77]

From this, we can see that the fourth class is (55 – 66], which has a width of 11. Therefore, the answer is (c) 14 and (63 – 78].

PV = PMT / r

where:

PV is the present value

PMT is the payment per period

r is the interest rate per period

Since the payments are made annually and the interest rate is 14.3% per year, the interest rate per period is also 14.3%. Thus:

PV = $4,100 / 0.143 = $28,671.33

At a current interest rate of 14.3%, Amazon Rafting would need to invest this much in order to receive permanent $4,100 yearly payments.

Now, using the following calculation, we can determine the price of the caravan using the present value of the perpetuity and the future value of the special payment:

[tex]FV = PV * (1 + r)^n + SP[/tex]

where:

FV is the future value

PV is the present value of the perpetuity

r is the interest rate per period (14.3% per year)

n is the number of periods (5 years)

SP is the special payment of $8,700 over 5 years

We know that:

P(A fails) = 0.35, which means P(A works) = 0.65

P(A and B fail) = 0.22

P(B fails alone) = 0.3, which means P(B works) = 0.7

To find (i) P(A fails alone), we need to subtract the probability of A and B failing together from the probability of A failing:

P(A fails alone) = P(A fails) - P(A and B fail) = 0.35 - 0.22 = 0.13

Therefore, the probability of A failing alone is 0.13.

To find (ii) P(A fails given that B has failed), we need to use Bayes' theorem:

P(A fails | B fails) = P(A∩B) / P(B fails)

We already know that P(A∩B) = 0.22 and P(B fails) = 0.3. So, we can substitute these values to get:

P(A fails | B fails) = 0.22 / 0.3 = 0.7333...

Therefore, the probability of A failing given that B has failed is approximately 0.7333.

To determine the quadrant(s) in which the solutions lie for an angle in the range of 0 < θ < 2π (or 0 to 360 degrees), there are several steps to follow.

Firstly, we need to identify the reference angle. This is the angle formed between the terminal arm of the angle and the x-axis in the standard position.

Next, we need to determine the sign of the angle, which is based on whether the terminal arm is located in the positive or negative x-axis, and the positive or negative y-axis.

Then, we need to use the inverse trigonometric functions (such as sin^-1, cos^-1, or tan^-1) to determine the exact angle measure. This step is important because it ensures that we obtain the angle measure within the desired range of 0 < θ < 2π.

Once we have the exact angle measure, we can determine the quadrant(s) in which the solution lies. This is based on the signs of the trigonometric functions in each quadrant. For example, if the sine and cosine are positive, the angle lies in the first quadrant. If the sine is positive and the cosine is negative, the angle lies in the second quadrant. If the sine and cosine are negative, the angle lies in the third quadrant. And if the sine is negative and the cosine is positive, the angle lies in the fourth quadrant.

In summary, to determine the quadrant(s) in which the solutions lie for an angle in the range of 0 < θ < 2π, we need to identify the reference angle, determine the sign of the angle, use the inverse trigonometric functions to find the exact angle measure, and then use the signs of the trigonometric functions in each quadrant to determine the quadrant(s) in which the solution lies.
A general description of the steps used to determine the quadrant(s) in which the solutions lie for an angle in the range of 0 < θ < 2π (or 0 to 360 degrees) involves understanding the angle, reference angle, and quadrant relationships. Here are the steps:

1. Convert the angle (θ) into standard position, which means placing the vertex at the origin and the initial side along the positive x-axis. If the angle is given in degrees, convert it to radians (if needed) using the conversion factor: 1 radian = 180/π degrees.

2. Identify the reference angle (α). The reference angle is the acute angle formed between the terminal side of the angle (θ) and the x-axis. To find the reference angle, use the following rules:
- If θ is in the first quadrant, α = θ
- If θ is in the second quadrant, α = π - θ
- If θ is in the third quadrant, α = θ - π
- If θ is in the fourth quadrant, α = 2π - θ

3. Determine the quadrant(s) in which the angle (θ) lies using the reference angle (α) and the inverse trigonometric functions.

The inverse trigonometric functions (e.g., sin⁻¹, cos⁻¹, and tan⁻¹) can help in finding the corresponding angle(s) for a given trigonometric function value. Depending on the function and value, one or two quadrants may be determined as solutions.

4. Once the quadrant(s) are identified, the solutions for the angle (θ) can be written using the reference angle (α) and the relevant inverse trigonometric function.

By following these steps, you can effectively determine the quadrant(s) in which the solutions lie for an angle within the specified range.

Step-by-step explanation:

Why did many Americans consider César Chávez a hero in the '60s and '70s?

The parent functions that have negative y-values are those that are located below the x-axis.

These functions include the linear function with a negative slope, the quadratic function with a negative leading coefficient, the cubic function with a negative leading coefficient, and any other odd-degree polynomial function with a negative leading coefficient. Additionally, any exponential function with a negative base will also have negative y-values.

For example, the linear function y = -2x has a negative slope and will have negative y-values for any x values greater than zero. Similarly, the quadratic function y =

[tex]x^2[/tex]

will have negative y-values for all x values. The cubic function y =

[tex]-2x^3[/tex]

and the exponential function y = -

[tex]3^x[/tex]will also have negative y-values.

Any parent function that is located below the x-axis will have negative y-values. This can be determined by examining the equation of the function and its graphical representation.
