Higher the weight of the variable in a standardized predictor environment, we can say that the particular variable has a higher discriminating power. True or False?

Answer:

A

Step-by-step explanation:

Mateo has a balance of 1,460.89 dollars, and he knows that check 354 was for 25.79 dollars. Therefore, to find the amount, in dollars, X, of check 353, Mateo needs to subtract the known amount of check 354 from his current balance.

So, the equation that can be used to find the amount of check 353 is:

1,460.89 - 25.79 = X

Thus the correct answer is:

A. 1,225.70 + x = 1,460.89

The point (3, -2) can be classified as a local maximum of the polynomial function f(x).

What is polynomial ?

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables.

In this case, the values f(3) = -2, f'(3) = 0, and f''(3) = -2 give us information about the graph of the polynomial function f(x) at the point x = 3.

First, f(3) = -2 means that the y-coordinate of the point (3, -2) is -2, so the point (3, -2) is on the graph of f(x).

Second, f'(3) = 0 means that the slope of the tangent line to the graph of f(x) at the point x = 3 is 0. This means that at x = 3, the graph of f(x) has a horizontal tangent line, which is a sign of a local maximum or minimum of the function.

Third, f''(3) = -2 means that the second derivative of f(x) at x = 3 is -2. This means that the graph of f(x) is concave down at x = 3. A concave down graph means that the function is decreasing at x = 3, so the point (3, -2) is a local maximum of the function.

Therefore, the point (3, -2) can be classified as a local maximum of the polynomial function f(x).

A linear inequality that forms a system of linear inequalities with y > x - 1, whose solution set is the empty set, is y < x - 1.

When taken together, y > x - 1 and y < x - 1 form a system of linear inequalities, but these two inequalities are contradictory and cannot both be true at the same time. Therefore, the solution set of this system is the empty set, meaning there are no solutions that satisfy both inequalities.

To explain in detail, consider the line y = x - 1. When x = 1, y = 0. If y > x - 1, then y must be greater than 0 when x = 1. But if y < x - 1, then y must be less than 0 when x = 1. These two inequalities cannot both be true at the same time, so the solution set of the system is the empty set.

This shows that when two contradictory linear inequalities are taken together, their solution set is the empty set. In this case, y > x - 1 and y < x - 1 are contradictory, and so their solution set is the empty set.

Answer: The data shows an association between the type of instructor and a certification in CPR. The association is that swimming instructors are less likely than tennis instructors to be certified in CPR. This can be seen from the frequency table, where all the swimming instructors are not certified in CPR, while only 4 out of 12 tennis instructors are not certified in CPR, so yes, the data does show an association between the type of instructor and a certification in CPR.

Step-by-step explanation:

The two-way frequency table shows the number of instructors who are certified or not certified in CPR, broken down by type of instructor (swimming or tennis). The data in the table allows us to see the relationship between the two variables (type of instructor and certification in CPR) and whether there is an association between them.

An association means that the values of one variable are related to the values of another variable in some way. In this case, the type of instructor (swimming or tennis) is related to whether or not the instructor is certified in CPR. The data shows that the proportion of swimming instructors who are not certified in CPR (100%) is higher than the proportion of tennis instructors who are not certified in CPR (33%). This indicates that there is an association between type of instructor and certification in CPR, with swimming instructors being less likely to be certified in CPR than tennis instructors.

It is important to note that this association does not necessarily imply causation, meaning that being a swimming instructor does not cause one to not be certified in CPR, but it could be the other way around, or it could be due to some other factors that the data does not show.

Answer:

To find the constant of proportionality between the cost of the game tickets and the number of tickets purchased, we can write an equation that represents the relationship between the two values. Let's call the constant of proportionality "k".

Step 1: Write an equation for Rocko's purchase:

12.50 = k * 25

Step 2: Solve for k:

k = 12.50 / 25 = 0.50

Step 3: Write an equation for Louisa's purchase:

17.50 = k * 36

Step 4: Substitute the value of k from step 2 into the equation:

17.50 = 0.50 * 36

Step 5: Check if the value of k is the same for both equations:

17.50 / 36 = 0.50

The constant of proportionality is 0.50, which means that for each additional game ticket purchased, the cost increases by $0.50.

The solution of all the measures of the angles are,

1) m ∠A = 63°

2) m ∠B = 138°

3) m ∠C = 117°

4) m ∠D = 137.22°

Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.

In figure 1;

Measure of angle A and angle B are vertically opposite angle and hence both are equal to each other.

⇒ ∠A = ∠B

⇒ 2x + 35 = 8x - 49

⇒  35 + 49 = 8x - 2x

⇒ 84 = 6x

⇒ x = 14

Thus, The value of m ∠A = 2x + 35

                                       = 2×14 + 35

                                       = 28 + 35

                                       = 63°

2) By the figure, the sum of both indicated angle is 180°.

Hence, We get;

⇒ 10x - 18 + 15x + 48 = 180

⇒ 25x + 30 = 180

⇒ 25x = 180 - 30

⇒ 25x = 150

⇒ x = 6

Thus, The value of m ∠B = 15x + 48

                                       = 15×6 + 48

                                       = 90 + 48

                                       = 138°

3) By the figure, Both angles are alternate angle of parallel lines and hence both are equal.

So, We get;

⇒ 7x + 5= 12x - 75

⇒ 5 + 75 = 12x - 7x

⇒ 80 = 5x

⇒ x = 16

Thus, The value of m ∠C = 7x + 5

                                       = 7×16 + 5

                                       = 112 + 5

                                       = 117°

4) By the figure, the sum of both indicated angle is 180°.

Hence, We get;

⇒ 27x - 21 + 10x - 16 = 180

⇒ 37x - 37 = 180

⇒ 37x = 180 + 37

⇒ 37x = 217

⇒ x = 217/37

⇒ x = 5.86

Thus, The value of m ∠D = 27x - 21

                                       = 27×5.86 - 21

                                       = 158.22 - 21

Rate of changing per second = - 3

Let "x" be side of square. So, x = 10. We have to determine the rate of change of the area. So, Rate of change in side ,x per unit time = dx/dt = -3 . As we know, the area of a polygon is equals to total space occupied by shape or polygon.

So, Area of square, A = side × side . In this case, Area of square , A = x² --(1)

Differentiating equation (1) with respect to time "t",

=> dA/dt = d/dt ( x²)

=> dA/dt = 2x dx/dt ( using derivative formula )

here,dx/dt --> rate of changing of side of square

Substitute the value of dx/dt = -3 in above derivative, dA/dt = 2x dx/dt

=> dA/dt = 2x (-3)

=> dA/dt = 2×(10)(-3) ( since side, x = 10)

Answer: look below love :))

Step-by-step explanation: To find out how much Amir will have in the account after 23 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A is the final amount

P is the initial principal (the amount Amir deposited)

r is the annual interest rate (2.25%)

n is the number of times the interest is compounded per year (let's assume it is compounded annually)

t is the number of years

So, we can plug in the given values:

A = 1390(1 + 0.0225)^(1*23)

A = 1390(1.0225)^(23)

A = 1390 * 2.6388955

A = 3655.922

So Amir will have £3655.922 in the account after 23 years with 2.25% compound interest.

Using the Pythagorean Theorem we know that the ladder can reach up to the building 85ft.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental Euclidean geometry relationship between the three sides of a right triangle.

This statement states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

So, we have:

Hypotuenese is 70ft long and Height is 25ft long.

Then, the base would be:

c² = a² + b²

70² = 25² + b²

b² = 4,900 - 625

b² = 7,275

b = √7275

A tridiagonal matrix is a type of matrix that consists of three diagonals. The main diagonal is the diagonal that runs from the top left corner of the matrix to the bottom right corner. The secondary diagonal is the diagonal that runs from the top right corner of the matrix to the bottom left corner. The third diagonal is the diagonal that runs from the top left corner of the matrix to the bottom right corner, one row above the main diagonal. The number of non-zero values in a tridiagonal matrix of size n x n can be calculated using the formula: Nnz = 2n + (n-2). For example, for a tridiagonal matrix of size 4 x 4, the number of non-zero values would be 2 x 4 + (4-2) = 10.
