In regression analysis, the variable that is used to explain the change in the outcome of an experiment, or some natural process, is called independent variable

It is a branch of mathematics that deals with the occurrence of a random event.

The variable that is used to explain the change in the outcome of an experiment or some natural process in regression analysis is called the independent variable or predictor variable.

This variable is used to predict or explain the values of the dependent variable, which is the outcome variable being studied.

In other words, the independent variable is the variable that is manipulated or controlled by the experimenter or researcher, and its effect on the dependent variable is measured.

Hence, in regression analysis, the variable that is used to explain the change in the outcome of an experiment, or some natural process, is called independent variable

The balloon's vertical distance above the ground is 430 feet.

You look straight parallel to the ground. But when you have to watch something down, then you take your sight down by moving your head up.

The angle from horizontal to the point where you stopped your head is called the angle of depression.

From a hot-air balloon, Brody measures a 39° angle of depression to a landmark that's 532 feet away, measuring horizontally.

The angle of depression = 39°

The base = 532

We need to find the vertical distance consider perpendicular.

\(\rm Tan \theta = \dfrac{perpendicular}{base } \\\\\rm Tan 39 = \dfrac{perpendicular}{532} \\\\\rm Tan 39 \times 532 =perpendicular\\\\0.80 \times 532\\\\P = 430.80\)

Alternate interior angles are known to be angles that are created if a transversal are said to pass two coplanar lines.

Note that they tend to lie on the inside of the parallel lines and also on the opposite sides of the transversal.

Since Alternate Interior angles are said to be opposite one another, they are known to be congruent (that is of the same measure). Alternate Interior angles which are seen to be on the same side of the transversal line are said to be consecutive interior angles.

Answer:

Elephants are worth 4 the other one is worth 1.

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

we have 2 elephants, and 4 horses are equal to 12 horses

First, lets form an equation. Let the elephants be e and the horses be h

2e + 4h = 12h

The horses are a variable that's equal on both sides, so we can remove them. Do this by subtracting 4h from both sides of the equals sign.

2e = 8h

Hence, 2 elephants are as strong as 8 horses. But, this equation is not simplified, the question asks for 1 elephant, so we divide by 2 on both sides of the equals sign.

hence, e = 4h

One elephant is as strong as 4 horses.

Step-by-step explanation:

The spot on the shoreline is moving at a rate of about 1.764 feet per minute when it is 13 feet from the point on the shoreline closest to the lighthouse.

What is differentiation?

Differentiation is a mathematical operation that is used to find the rate at which a function changes. More specifically, it is the process of finding the derivative of a function.

The derivative of a function at a given point is a measure of how quickly the function is changing at that point. It gives the slope of the tangent line to the graph of the function at that point. The derivative can be thought of as the instantaneous rate of change of the function at that point.

Let's call the point on the shoreline closest to the lighthouse "P". We know that the distance from the spotlight to P is 130 feet, and we want to find the rate at which the distance from the spotlight to P changes when the spotlight is 13 feet from P.

To do this, we can use the chain rule to differentiate the distance formula with respect to time. Let's call the distance between the spotlight and P "d". Then:

                           d²= 130² + x²

Taking the derivative of both sides with respect to time gives:

                   2d * dd/dt = 0 + 2x * dx/dt

We can solve for dd/dt by plugging in the values we know:

130² + 13² = d²

d = \(\sqrt{(130^2 + 13^2)}\) = 130.325 ft

2(130.325) * dd/dt = 2(13) * dx/dt

dd/dt = (13/130.325) * dx/dt

We know that the spotlight revolves at a rate of 281 rad/min, or 281/2π ≈ 44.7 revolutions per minute. Each revolution of the spotlight covers a distance of 2π * 130 feet, so its speed is:

(2π * 130 ft/rev) * (44.7 rev/min) = 18410.8 ft/min

To find dx/dt when x = 13, we need to find the angular velocity of the spotlight at that point. The spotlight makes one full revolution every 60/14 ≈ 4.29 seconds, so its angular velocity is:

2π radians/rev ÷ 4.29 s/rev = 1.47 radians/s

At any given moment, the angle between the spotlight and the line connecting the lighthouse and P is equal to the arctangent of x/130. When x = 13, this angle is:

arctan(13/130) ≈ 5.71°

The rate at which the angle is changing is equal to the angular velocity of the spotlight, so we can use the formula for the derivative of the arctangent to find dx/dt:

dx/dt = 130 * tan(5.71°) * (1.47 radians/s)

dx/dt ≈ 17.602 ft/min

Finally, we can substitute this value into the expression we found for dd/dt:

dd/dt = (13/130.325) * 17.602

dd/dt ≈ 1.764 ft/min

So the spot on the shoreline is moving at a rate of about 1.764 feet per minute when it is 13 feet from the point on the shoreline closest to the

The smallest share of marbles received by the girls is A = 40

Given data ,

To determine the smallest share received by the girls, we need to find the smallest value among the three ratios given for the girls.

The total number of marbles shared is 220.

Let's assign the values for the ratios as follows:

Ratio 1: 2x

Ratio 2: 4x

Ratio 3: 5x

On simplifying the proportions , we get

The sum of the ratios should equal the total number of marbles:

2x + 4x + 5x = 220

Combining like terms, we have:

11x = 220

Dividing both sides of the equation by 11, we get:

x = 20

Now, let's substitute the value of x back into the ratios:

Ratio 1: 2x = 2(20) = 40

Ratio 2: 4x = 4(20) = 80

Ratio 3: 5x = 5(20) = 100

Therefore , the solution of the given problem of triangle comes out to be the relationship between s,t and u is u²= t²+s².

Given that it has three sides and three vertices, a triangle qualifies as a polygon. It is a fundamental geometric figure. Triangle ABC is the term used to refer to a triangle containing the vertices A, B, and C. When the three points are not collinear, a unique plane and triangle in Euclidean geometry are discovered. Triangles are polygons because they have three sides and three corners. The points where the three sides of the triangle converge are referred to as the triangle's corners. Three triangle angles are multiplied to yield 180 degrees.
