Probability that the total weight for the two animals is 225 pounds or more is 0.17.

We need to use the joint probability distribution for X and Y, where X and Y are the weights of the first and second animals, respectively. Let's denote the joint probability distribution as P(X=x, Y=y).

From the table given, we can see that the possible values of X and Y are 100, 120, and 140 pounds. To find the probability that the total weight is 225 pounds or more, we need to sum the joint probabilities for all pairs of (X,Y) that satisfy X+Y≥225.

These pairs are:

So, we have:

P(X+Y≥225) = P(X=120, Y=120) + P(X=100, Y=120) + P(X=120, Y=100) + P(X=100, Y=140) + P(X=140, Y=100) + P(X=120, Y=140) + P(X=140, Y=120) + P(X=140, Y=140)

Substituting the values from the table, we get:

P(X+Y≥225) = 0.04 + 0.03 + 0.03 + 0.01 + 0.01 + 0.02 + 0.02 + 0.01

P(X+Y≥225) = 0.17

Therefore, the probability that the total weight for the two animals is 225 pounds or more is 0.17.

So the response closest to 0.17 is 0.195.

The inverse of the matrix with orthonormal columns is simply its transpose.

If a square matrix has orthonormal columns, it means that the dot product of any two columns is zero, except when the two columns are the same, in which case the dot product is 1. This implies that the columns are linearly independent, because if any linear combination of the columns were zero, then the dot product of that combination with any other column would also be zero, which would imply that the coefficients of the linear combination are zero.

Since the matrix has linearly independent columns, it follows that the matrix is invertible. The inverse of the matrix is simply the transpose of the matrix, since the columns are orthonormal. To see why, consider the product of the matrix with its transpose:

\((A^T)A = [a_1^T; a_2^T; ...; a_n^T][a_1, a_2, ..., a_n]\\ = [a_1^T a_1, a_1^T a_2, ..., a_1^T a_n; \\ a_2^T a_1, a_2^T a_2, ..., a_2^T a_n; ... a_n^T a_1, a_n^T a_2, ..., a_n^T a_n]\)

Since the columns of the matrix are orthonormal, the dot product of any two distinct columns is zero, and the dot product of a column with itself is 1. Therefore, the diagonal entries of the product matrix are all 1, and the off-diagonal entries are all zero. This implies that the product matrix is the identity matrix, and so:

(A^T)A = I

Taking the inverse of both sides, we get:

\(A^T(A^-1) = I^-1(A^-1) = A^T\)

Therefore, the inverse of the matrix with orthonormal columns is simply its transpose.

The solutions to the equation -30x² + 9x + 60 = 0 are x = 5/2 and x = -4/5.

To solve the equation, we can start by bringing all the terms to one side to have a quadratic equation equal to zero. Let's go step by step:

-5/3 x² + 3x + 11 = -9 + 25/3 x²

First, let's simplify the equation by multiplying each term by 3 to eliminate the fractions:

-5x² + 9x + 33 = -27 + 25x²

Next, let's combine like terms:

-5x² - 25x² + 9x + 33 = -27

-30x² + 9x + 33 = -27

Now, let's bring all the terms to one side to have a quadratic equation equal to zero:

-30x² + 9x + 33 + 27 = 0

-30x² + 9x + 60 = 0

Finally, we have the quadratic equation in standard form:

-30x² + 9x + 60 = 0

Dividing each term by 3, we get:

-10x² + 3x + 20 = 0

(-2x + 5)(5x + 4) = -10x² + 3x + 20

So, the factored form of the equation -30x² + 9x + 60 = 0 is:

(-2x + 5)(5x + 4) = 0

Now we can set each factor equal to zero and solve for x:

-2x + 5 = 0 --> x = 5/2

5x + 4 = 0 --> x = -4/5

The expression where the greatest common factor (GCF) is factored completely is \(2x^3y + 18xy - 10x^2y - 90y = 2y(x^3 + 9x - 5x^2 - 45)\)

The expression completely factored in is

\(2y(x^3 + 9x - 5x^2 - 45) = 2y[x(x^2 - 5) + 9(x^2 - 5)]\\= 2y(x - 5)(x^2 + 9)\)

Please refer below for the remaining answers.

We have,

Part A:

To rewrite the expression 2x³y + 18xy - 10x²y - 90y so that the greatest common factor (GCF) is factored completely, we can factor out the common terms.

GCF: 2y

\(2x^3y + 18xy - 10x^2y - 90y = 2y(x^3 + 9x - 5x^2 - 45)\)

Part B:

To completely factor the expression, we can further factor the quadratic term.

\(2y(x^3 + 9x - 5x^2 - 45) = 2y[x(x^2 - 5) + 9(x^2 - 5)]\\= 2y(x - 5)(x^2 + 9)\)

Now,

Part A:

To determine the length of each side of the square given the area expression (9x² + 24x + 16), we need to factor it completely.

The area expression (9x² + 24x + 16) can be factored as (3x + 4)(3x + 4) or (3x + 4)².

Therefore, the length of each side of the square is 3x + 4.

Part B:

To determine the dimensions of the rectangle given the area expression (16x² - 25y²), we need to factor it completely.

The area expression (16x² - 25y²) is a difference of squares and can be factored as (4x - 5y)(4x + 5y).

Therefore, the dimensions of the rectangle are (4x - 5y) and (4x + 5y).

Now,

f(x) = 2x² - 5x + 3

Part A:

To find the x-intercepts of the graph of f(x), we set f(x) equal to zero and solve for x.

2x² - 5x + 3 = 0

The quadratic equation can be factored as (2x - 1)(x - 3) = 0.

Setting each factor equal to zero:

2x - 1 = 0 --> x = 1/2

x - 3 = 0 --> x = 3

Therefore, the x-intercepts of the graph of f(x) are x = 1/2 and x = 3.

Part B:

To determine if the vertex of the graph of f(x) is maximum or minimum, we can examine the coefficient of the x^2 term.

The coefficient of the x² term in f(x) is positive (2x²), indicating that the parabola opens upward and the vertex is a minimum.

To find the coordinates of the vertex, we can use the formula x = -b / (2a), where a and b are the coefficients of the quadratic equation.

For f(x),

a = 2 and b = -5.

x = -(-5) / (2 x 2) = 5/4

To find the corresponding y-coordinate, we substitute this x-value back into the equation f(x):

f(5/4) = 25/8 - 25/4 + 3 = 25/8 - 50/8 + 24/8 = -1/8

Therefore, the vertex of the graph of f(x) is at the coordinates (5/4, -1/8), and it is a minimum point.

Part C:

To graph f(x), we can start by plotting the x-intercepts, which we found to be x = 1/2 and x = 3.

These points represent where the graph intersects the x-axis.

Next,

We can plot the vertex at (5/4, -1/8), which represents the minimum point of the graph.

Since the coefficient of the x² term is positive, the parabola opens upward.

We can use the vertex and the symmetry of the parabola to draw the rest of the graph.

The parabola will be symmetric with respect to the line x = 5/4.

We can also plot additional points by substituting other x-values into the equation f(x) = 2x² - 5x + 3.

By connecting the plotted points, we can draw the graph of f(x).

The steps to graph f(x) involve plotting the x-intercepts, the vertex, and additional points, and then connecting them to form the parabolic curve.

The answer in part A (x-intercepts) and part B (vertex) are crucial in determining these key points on the graph.

Thus,

The expression where the greatest common factor (GCF) is factored completely is \(2x^3y + 18xy - 10x^2y - 90y = 2y(x^3 + 9x - 5x^2 - 45)\)

The expression completely factored in is

\(2y(x^3 + 9x - 5x^2 - 45) = 2y[x(x^2 - 5) + 9(x^2 - 5)]\\= 2y(x - 5)(x^2 + 9)\)

When training a classifier, the training set is used to learn the conditional probabilities.

The training set is used to learn the conditional probabilities because the training set is used to train the classifier on the patterns and features in the data, which in turn helps the classifier to learn the conditional probabilities of the different classes in the data.

The hold-out set and test set are used to evaluate the performance of the classifier and ensure that it is not overfitting to the training set.

By evaluating the classifier on data that it has not seen before, we can get a more accurate estimate of its true performance and the probability of correctly classifying new data.

Step-by-step explanation:

False. The complement of an event A, denoted by A', is the event consisting of all outcomes in the sample space S that are not in A.

In probability theory, a sample space S represents the set of all possible outcomes of an experiment or random phenomenon. An event A is a subset of the sample space S, representing a specific outcome or a combination of outcomes of interest.

The complement of event A, denoted by A', includes all the outcomes in the sample space S that are not part of event A. In other words, A' consists of all outcomes that do not satisfy the conditions for event A to occur.

For example, let's consider rolling a fair six-sided die. The sample space S consists of the numbers {1, 2, 3, 4, 5, 6}. Now, let event A be the event of rolling an odd number. In this case, A = {1, 3, 5}, and the complement of A, denoted by A', would be A' = {2, 4, 6}. A' includes all the outcomes that are not odd numbers.

It's important to note that the complement of an event A and the event itself together cover the entire sample space S. In other words, A and A' are mutually exclusive and exhaustive, meaning that any outcome must either be in A or in A'.

So, in summary, the complement of an event A is the set of all outcomes in the sample space S that do not belong to A.

To compute the given probabilities involving the standard normal random variable z, we can use the standard normal distribution table.

To find the probability P(−1.98 ≤ z ≤ 0.45), we need to look up the corresponding values in the standard normal distribution table. The table provides the area under the standard normal curve up to a given z-value.

First, we find the area to the left of z = −1.98 in the table, which is 0.0239. Then, we find the area to the left of z = 0.45, which is 0.6736. To find the desired probability, we subtract the smaller area from the larger one: P(−1.98 ≤ z ≤ 0.45) = 0.6736 - 0.0239 = 0.6497.

Box plots are a useful tool for summarizing and visualizing data, allowing for easy comparison and analysis of different data sets

A box plot is a graphical representation of a data set that shows the distribution of the data and some of its key statistical measures such as the median, quartiles and outliers.

The box plot consists of a box and whiskers that extend from the box.

The box represents the middle 50% of the data with the lower and upper quartiles forming the bottom and top of the box respectively.

The line inside the box represents the median is the middle value of the data set.

The whiskers extend from the box to the minimum and maximum values that are not outliers.

Outliers are values that are much larger or smaller than the other values in the data set are shown as individual points outside the whiskers.

Box plots can be used to compare the distributions of data sets, such as in the case of Jada's data on flights from Boston to San Diego on two different airlines.

By comparing the medians quartiles and ranges of the box plots for the two airlines Jada can get a sense of which airline has more consistent flight times fewer delays or other factors that are important to her.

Additionally Jada can identify any outliers in the data set that may be worth investigating further.
