The linear equation doesn't have a solution.

The linear equation given is illustrated as: 4x-(2x-1) = x+5+x-6

This will be solved thus:

4x - 2x + 1 = x+5+x-6

4x - 2x + 1 = 2x - 1.

2x + 1 = 2x - 1

Collect like terms

2x - 2x = -1 - 1

0 = -2

Answer:

|A| - C = 5

Step-by-step explanation:

The maximum value that a sine function can have is 1, and the minimum value is -1.

With this information, to find the minimum value of y, we can use sin(Bx) = -1, and to find the maximum value, we can use sin(Bx) = 1. Then, we have that:

19 = A + C

-5 = -A + C

Summing both equations, we have:

14 = 2C

C = 7

Now, to find the value of A, we can use the first equation:

19 = A + C

19 = A + 7

A = 12

So the value of |A| - C is:

|12| - 7 = 12 - 7 = 5

Answer:

the answer is negative correlation

Step-by-step explanation:

The statement which is true is: A. The slope of Function A is greater than the slope of Function B, and the y-intercept of Function A is less than the y-intercept of Function B.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:

y - y₁ = m(x - x₁)

Where:

First of all, we would find the slope of function A;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (3 + 5)/(3 + 1)

Slope (m) = 8/4

Slope (m) A = 2.

At data point (3, 3) and a slope of 2, a function for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 3 = 2(x - 3)

y = 2x - 3

For function B, we have:

x/a + y/b = 1

x/-5 + y/3 = 1

Slope (m) B = (3 - 0)/(0 + 5)

Slope (m) B = 3/5.

y = 3x/5 + 3

The alternative hypothesis states the presence of an association between class level and IQ score. The statement "Not all the population 1Q means are the same" is incorrect as it does not indicate any association between the two variables. A more appropriate alternative hypothesis would be "At least one of the population IQ means will be different" which suggests that the population IQ means are not all the same and there is an association between class level and IQ score.
In more technical terms, the alternative hypothesis can be expressed as:

The area of the triangle from the parallelogram is; 14 sq.units

To find the area of the triangle, let us first of all think of the given lines extended to form a parallelogram.

Now, we know that the diagonal of a parallelogram divides the parallelogram into two equal triangles and as such half of the area of a parallelogram equals the area of the half triangle it forms.

Formula for area of parallelogram is;

A_p = Base * height

Base = 7 units

Height = 4 units

Thus;

A_p = 7 * 4

A_p = 28 sq.units

Thus;

Area of triangle = ¹/₂ * 28

Step-by-step explanation:

a) The probability after 3 years is calculated using geometric Brownian motion and the standard normal distribution. b) The expected value of the stock price after 3 years is found by geometric Brownian motion.

a) To find the probability that the stock price is more than $80 after 3 years, we first need to calculate the standardized value of S(3) - $80.

Using the formula for geometric Brownian motion, we have S(3) = $75 * \(e^{(0.05-(0.25^{2} )/3} *3+0.25\) * W(3)), where W(3) represents a standard Brownian motion.

Let Z be the standardized value:

Z = (ln(S(3)/$75) - ((0.05 - (\(0.25^{2}\))/2) * 3))/ (0.25 * \(\sqrt{\)(3))

To calculate the probability, we need to find P(Z > z), where z is the standardized value corresponding to $80. We can look up this probability in a standard normal distribution table or use a calculator to find the cumulative distribution function (CDF) of the standard normal distribution for the given value of z.

b) To find the expected value of the stock price after 3 years, we use the formula for geometric Brownian motion: E[S(t)] = S(0) * e^(μt).

Plugging in the values, we have E[S(3)] = $75* \(e^{0.05*3}\) Evaluating this expression will give us the expected value of the stock price after 3 years.

The required value of x is 4√2.

Labelling the given figure,

For the given triangle ABD,

AC/CB = DC/AC

A triangle is a three-sided polygon with three edges and three vertices in geometry. The total of a triangle's interior angles equals 180 degrees, which is its most essential feature. This is known as the angle sum property of a triangle.

If ABC is a triangle, it is denoted as ABC, where A, B, and C are the triangle's vertices. on Euclidean geometry, a triangle is a two-dimensional form represented by three non-collinear points on a single plane.

Here we have,

AC = x

CB = 8

DC = 4

Now putting these values,

⇒ x/8 = 4/x

⇒  x²  = 32

formula us v = 3/4 × pi × half of the diameter (radius)

The value of that makes the volume of the parallelepiped with edges oa, ob, and oc equal to 3 units is  α = 1

The volume of a parallelopiped with sides a, b and c is V = a.(b × c)

Now, consider the parallelepiped with edges oa, ob, and oc, where a(2,1,0), (1,2,0), and c(0,1,α). To find the real number α>0 such that the volume of the parallelepiped is 3 units, we proceed as follows.

We know that the volume of the parallelopiped with sides a, b and c is  a.(b × c) where

Now  a.(b × c) =det \(\left[\begin{array}{ccc}2&1&0\\1&2&0\\0&1&\alpha \end{array}\right]\)

So,  a.(b × c) = 2(2 × α - 1 × 0) - 1(1 × α - 0 × 0) + 0(1 × 1 - 2 × 0)

= 2(2α - 0) - (α - 0) + 0(1 - 0)

= 2(2α) - (α) + 0(1)

= 4α - α + 0

= 3α + 0

= 3α

Now since the volume of the parallelopied is 3 units, we have that

a.(b × c) = 3

3α = 3

α = 3/3

α = 1

Answer:

2x+59.

Step-by-step explanation:

Let J represent Jessica's weight and R represent Ronda's weight.

Jessica weighs x+34 pounds. Thus:

\(J=x+34\)

Ronda weighs 12 pounds less than Jessica. In other words:

\(R=J-12=(x+34)-12\\R=x+22\)

The sum of their weights, therefore, is:

\(J+R\\=(x+34)+(x+22)=2x+56\)

Now, if Jessica gains 5 pounds and Ronda loses 2 pounds, the net gain of the total weight would be 3 pounds. Thus, we only need to add 3 to the original total to find the sum of their new weights:

\(2x+56+3=2x+59\)

The sum of the new [weights] is represented by 2x+59.

The ratio of f to g to h is:

1:3:5

First, we know that g is the 60% of h, then we can write:

g = 0.6*h

Now we can write the 0.6 as a fraction, then 0.6 = 3/5.

g = (3/5)*h

So we can write:

5*g = 3*h

So the ratio of g to h is 3:5

Now, we know that f is a third of g:

f = (1/3)*g

3f = g

So the ratio of f to g is:

1:3

notice that the value that represents the proportion of g is 3 in both ratios, so we can just write:

The solution to the given differential equation 2xy(dy/dx) = y², with the initial condition y(2) = 3, is y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\).

To solve the given differential equation

2xy(dy/dx) = y²

We will use separation of variables and integrate to find the solution.

Start with the given equation

2xy(dy/dx) = y²

Divide both sides by y²:

(2x/y) dy = dx

Integrate both sides:

∫(2x/y) dy = ∫dx

Integrating the left side requires a substitution. Let u = y², then du = 2y dy:

∫(2x/u) du = ∫dx

2∫(x/u) du = ∫dx

2 ln|u| = x + C

Replacing u with y²:

2 ln|y²| = x + C

Using the properties of logarithms:

ln|y⁴| = x + C

Exponentiating both sides:

|y⁴| = \(e^{x + C}\)

Since the absolute value is taken, we can remove it and incorporate the constant of integration

y⁴ = \(e^{x + C}\)

Simplifying, let A = \(e^C:\)

y^4 = A * eˣ

Taking the fourth root of both sides:

y = (A * eˣ\()^{1/4}\)

Now we can incorporate the initial condition y(2) = 3

3 = (A * e²\()^{1/4}\)

Cubing both sides:

27 = A * e²

Solving for A:

A = 27 / e²

Finally, substituting A back into the solution

y = ((27 / e²) * eˣ\()^{1/4}\)

Simplifying further

y = (27 *  e⁽ˣ⁻²⁾\()^{1/4}\)

Therefore, the solution to the given differential equation with the initial condition y(2) = 3 is

y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\)

The car will cost $ 800 after a depreciation time of approximately 6 years.

Herein we are informed about the case of a car bought in 2011 at a cost of $ 36,000 and that depreciates linearly every year. Then, the depreciation function is described below:

c(t) = c' + m · t

Where:

If we know that c(0) = 36,000, c(4) = 12,000 and c(t) = 800, then the depreciation rate is:

m = (12,000 - 36,000) / (4 - 0)

m = - 24,000 / 4

m = - 6,000

800 = 36,000 - 6,000 · t

6,000 · t = 35,200
