Answer:

t/n = 5

Step-by-step explanation:

Now:

Let t = Tom's age now.

Let s = sum of children's ages now.

n years ago:

Tom's age = t - n

Each of the three children was n years younger, so the sum of their ages n years ago is s - 3n

t = s

t - n = 2(s - 3n)

t = s

t - n = 2(t - 3n)

t = s

t - n = 2t - 6n

t = s

-t = -5n

-t/n = -5

t/n = 5

The required answer is  a regression with a higher r2 will always be preferable to one with a lower r2 IS TRUE.

True. A regression with a higher R2 value will generally be preferable to one with a lower R2 value because a higher R2 indicates that the regression model explains a greater proportion of the variance in the dependent variable.

It indicates a stronger correlation between the independent and dependent variables, and thus, a better fit for the model. However, it is important the sole criterion for evaluating a regression model, and other factors such as statistical significance and practical ..

The  regression analysis is a set of statistical processes for estimating the relationships between a dependent variable and one or more independent variables . The most common form of regression analysis is linear regression, in which one finds the line that most closely fits the data according to a specific mathematical criterion. For example, the method of ordinary least squares computes the unique line that minimizes the sum of squared differences between the true data and that line . For specific mathematical reasons , this allows the researcher to estimate the conditional expectation  of the dependent variable when the independent variables take on a given set of values. Less common forms of regression use slightly different procedures to estimate alternative location parameters because quantile regression or Necessary Condition Analysis or estimate the conditional expectation across a broader collection of non-linear models

However, it's important to consider other factors, such as the complexity of the model and its relevance to the research question, when evaluating the overall quality and suitability of a regression model.

Step-by-step explanation:

1/20 of 100% is 5%. So that means 5%

The expression when evaluated is p^21/200

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

\(5^{-2} x 125 x p^{15} / 10^{3} x p^{-6}\)

Express properly

So, we have the following representation

(5^-2 * 125 * p^15)/(10^3 * p^-6)

Evaluate the products of common factors

This gives

(5 * p^15)/(10^3 * p^-6)

Apply the law of indices

(5 * p^21)/10^3

So, we have

5p^21/1000

Divide 5 and 1000 by 5

Answer:

AC=42

EB=21

BC=26

thats all i know, sorry hope u figure it out

Step-by-step explanation:

The sides are AC = 42, EB = 21, BC = 26, AB = 38 and the measures of angles are ∠ADC = 90°, ∠ABD = 38°, ∠BCA = 52°, ∠DEC = 104°.

Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles

Given is a rectangle ABCD.

AC and BD are diagonals intersecting at E.

Given  DB=42, AD=26 and m ∠DAE=52°

(a) Diagonals of a rectangle are of equal length.

AC = DB = 42

(b) Diagonals of a rectangle bisect each other.

DE = EB = DB / 2 = 42/2 = 21

(c) Opposite side are equal.

BC = AD = 26

(d) Using Pythagoras theorem,

AB = \(\sqrt{(AC)^2-(BC)^2}\) = \(\sqrt{42^2-26^2}\) = 37.947 ≈ 38

(e) Measure of all the interior angles in a rectangle is 90°.

So, ∠ADC = 90°

(f) Given ∠DAE = 52°

∠BAE = 90° - 52° = 38°

ΔBAE is an isosceles triangle, since the two sides which are the bisectors of the diagonals are equal.

So, ∠ABD = ∠BAE = 38°

(g) ∠BCA = ∠DAE [Alternate interior angles]

∠BCA = 52°

(h) Sum of interior angles of a triangle is 180°.

∠DEC + ∠BDC + ∠ACD = 180°

∠BDC = ∠ABD = 38° and ∠ACD = ∠BAE = 38°

∠DEC = 180° - (38° + 38°)

          = 104°

Hence the measures are found.

The equation of the path of the parabola is y = a(x - 13)² + 27

Given data ,

To represent the path of Al's toss, we can assume that the path is a parabolic trajectory.

The equation of a parabola in vertex form is given by:

y = a(x - h)² + k

where (h, k) represents the vertex of the parabola

Now , the balloon was released from the 10-yard line and landed at the 16-yard line, we can determine the x-values for the vertex of the parabola.

The x-coordinate of the vertex is the average of the two x-values (10 and 16) where the balloon was released and landed:

h = (10 + 16) / 2 = 13

Since the height of the balloon reached 27 yards, we have the vertex point (13, 27)

Now, let's substitute the vertex coordinates (h, k) into the general equation:

y = a(x - 13)² + k

Substituting the vertex coordinates (13, 27)

y = a(x - 13)² + 27

To determine the value of 'a', we need another point on the parabolic path. Let's assume that the highest point reached by the balloon is the vertex (13, 27).

This means that the highest point (13, 27) lies on the parabola

Substituting the vertex coordinates (13, 27) into the equation

27 = a(13 - 13)² + 27

27 = a(0) + 27

27 = 27

Hence , the equation representing the path of Al's toss is y = a(x - 13)² + 27, where 'a' can be any real number

A trapezoid is quadrilateral with exactly one pair of parallel sides. The parallel sides are called bases of the trapezoid. The nonparallel sides are referred to as the legs of trapezoid.

The median of a trapezoid is parallel to each base and the length of the median equals one-half the sum of the lengths of the two bases.

The probability of drawing a yellow marble on the next draw is 13/48, which is option A, 13%.

The probability of drawing a yellow marble in the next draw depends on whether the drawing process is with or without replacement.

If the drawing process is with replacement, meaning that the marble is put back into the bag after each draw, then the probability of drawing a yellow marble remains the same at 13/48.

If the drawing process is without replacement, meaning that the marble is not put back into the bag after each draw, then the probability of drawing a yellow marble changes. After 48 draws, there are 35 white marbles and 13 yellow marbles left in the bag.

where \(s_1\) and \(s_2\) are the standard deviations of the two samples, and n1 and n2 are the sample sizes.

Substituting the values given, we get:

Step-by-step explanation:

under the restrictions that c is negative to ensure strict concavity, the utility function u(w) = -(b - w)c displays increasing absolute risk aversion.

To ensure that u(w) is strictly increasing, we need the derivative of u(w) with respect to w to be positive for all values of w. Taking the derivative, we have du(w)/dw = -c. For u(w) to be strictly increasing, -c must be positive, which implies c must be negative.

To ensure that u(w) is strictly concave, we need the second derivative of u(w) with respect to w to be negative for all values of w. Taking the second derivative, we have d²u(w)/dw² = 0. Since the second derivative is constant and negative, u(w) is strictly concave.

Now, let's examine the concept of increasing absolute risk aversion. If a utility function u(w) exhibits increasing absolute risk aversion, it means that as wealth (w) increases, the individual becomes more risk-averse.

In the given utility function u(w) = -(b - w)c, when c is negative (as required for strict concavity), the absolute risk aversion increases as wealth (w) increases. This is because the negative sign implies that the utility function is concave, indicating that the individual becomes more risk-averse as wealth increases.

The value of y for point P (x, y) on the unit circle with coordinates (1, 0) is 0.

To determine the value of y for point P on the unit circle, we can utilize the Pythagorean identity, which relates the coordinates (x, y) on the unit circle.

The Pythagorean identity states that for any point (x, y) on the unit circle, x² + y² = 1.

In this case, the given point (1, 0) lies on the unit circle. Plugging these coordinates into the Pythagorean identity:

(1)² + y² = 1

1 + y² = 1

By subtracting 1 from both sides of the equation, we get:

y² = 0

To solve for y, we take the square root of both sides:

y = √0 = 0

Therefore, the value of y for point P (x, y) on the unit circle with coordinats (1, 0) is 0.
