Taking into account the definition of a system of linear equations, you little brother has 6 dimes.

A system of linear equations is a set of equations that have more than one unknown, appearing in several of the equations but necessarily in all of them. The equations relate the unknowns to each other.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. In other words, the values ​​of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.

In this case, a system of linear equations must be proposed taking into account that:

You know that:

The system of equations to be solved is

\(\left \{ {{d+n=42} \atop {0.1d + 0.05n=3}} \right.\)

It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, isolating the variable "n" from the first equation:

n= 42 -d

Replacing this expression in the second equation obtained:

0.1d + 0.05×(42 - d)= 3

Solving:

0.1d + 0.05×42 - 0.05d= 3

0.1d + 2.1 - 0.05d= 3

0.15d + 2.1=3

0.15d= 3 -2.1

0.15d= 0.9

d= 0.9÷0.15

d= 6

Finally, you little brother has 6 dimes.

Answer:

1)  x=16

2) x=15

3) x=10

Step-by-step explanation:

1)  Since the triangles are similar and the ratio of the sides is 1 : 2, 1/2=(3x-4)/(10x-72). Cross multiplying, we get 6x-8=10x-72.

10x-72=6x-8 |+72

10x=6x+64 |-6x

4x=64  |/4

x=16

2) Angles HGJ and KLJ are corresponding (they are equal angles).

So, 5x-2=9x-62.

5x-2=9x-62  |+62

5x+60=9x  |-5x

60=4x |/4

x=15

3) If KM is a perpendicular bisector, KJ=KL.

So, 4x+9=11x-61.

4x+9=11x-61 |-4x

9=7x-61   |+61

70=7x  |/7

x=10

The critical values for the confidence interval for the population variance, with n = 5 and a confidence level of 95%, are approximately 0.484 and 9.488.

To determine the critical values for the confidence interval of the population variance, we need to refer to the chi-square distribution table.

For a 95% confidence level and n = 5, we have (n-1) = 4 degrees of freedom.

To find the critical values, we need to determine the chi-square values that correspond to the upper and lower tails of the distribution, with an area of 0.025 in each tail.

From the chi-square distribution table or using a calculator, the critical values for a 95% confidence level and 4 degrees of freedom are approximately:

Lower Critical Value: 0.484

Upper Critical Value: 9.488

Therefore, the critical values for the confidence interval for the population variance, with n = 5 and a confidence level of 95%, are approximately 0.484 and 9.488.

The diagonals of a kite have lengths of 4 inches and 9 inches. Find the area of the kite. The area is 18 square inches

To find the area of a kite, we can use the formula:

Area = (diagonal 1 * diagonal 2) / 2

The area of a shape can be calculated using different formulas depending on the type of shape. For basic geometric shapes, such as squares, rectangles, triangles, and circles, there are specific formulas that relate the dimensions of the shape to its area.

For irregular shapes, the area can be determined by breaking the shape into smaller, more manageable components and summing their individual areas.

In this case, the diagonals of the kite have lengths of 4 inches and 9 inches. Plugging these values into the formula, we get:

Area = (4 * 9) / 2

Area = 36 / 2

Area = 18 square inches

Therefore, the area of the kite is 18 square inches.

Step-by-step explanation:

The partial derivative diffusivity equation for spherical flow is ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t, and for hemispherical flow, it is the same equation.

1. The partial derivative diffusivity equation for spherical flow is derived from the spherical coordinate system and applies to radial flow in a spherical geometry. It can be expressed as ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t.

2. The partial derivative diffusivity equation for hemispherical flow is derived from the hemispherical coordinate system and applies to radial flow in a hemispherical geometry. It can be expressed as ∂²p/∂r² + (1/r) ∂p/∂r = ϕμC/k ∂p/∂t.

1. For the derivation of the partial derivative diffusivity equation for spherical flow, we consider a spherical coordinate system with the radial direction (r), the azimuthal angle (θ), and the polar angle (φ). By assuming steady-state flow and neglecting the other coordinate directions, we focus on radial flow. Applying the Laplace operator (∇²) in spherical coordinates, we obtain ∇²p = (1/r²) (∂/∂r) (r² ∂p/∂r). Simplifying this expression, we arrive at ∂²p/∂r² + (1/r) ∂p/∂r.

2. Similarly, for the derivation of the partial derivative diffusivity equation for hemispherical flow, we consider a hemispherical coordinate system with the radial direction (r), the azimuthal angle (θ), and the elevation angle (ε). Again, assuming steady-state flow and neglecting the other coordinate directions, we focus on radial flow. Applying the Laplace operator (∇²) in hemispherical coordinates, we obtain ∇²p = (1/r²) (∂/∂r) (r² ∂p/∂r). Simplifying this expression, we arrive at ∂²p/∂r² + (1/r) ∂p/∂r.

In both cases, the term ϕμC/k ∂p/∂t represents the source or sink term, where ϕ is the porosity, μ is the fluid viscosity, C is the compressibility, k is the permeability, and ∂p/∂t is the change in pressure over time.

These equations are commonly used in fluid mechanics and petroleum engineering to describe radial flow behavior in spherical and hemispherical geometries, respectively.

This means that Parker performed very well on the history exam, since his score is much higher than the average score in the class.

Step 1: Understand the concept of a z-score.

A positive z-score means that the data point is above the mean, while a negative z-score means that the data point is below the mean.

Step 2: Determine the mean and standard deviation of the normal distribution.

Since we are told that a normal model describes student scores in a history class, we can assume that the distribution of scores is normal. We need to know the mean and standard deviation of the distribution to calculate Parker's z-score.

Let's assume that the mean score in the class is 80 and the standard deviation is 10.

μ = 80

σ = 10

Step 3: Calculate Parker's raw score.

To calculate Parker's raw score, we need to use the formula for z-scores and solve for x:

z = (x - μ) / σ

We know that Parker's z-score is 2.5, and we know the values of μ and σ. Solving for x, we get:

2.5 = (x - 80) / 10

25 = x - 80

x = 105

So, Parker's raw score is 105.

Step 4: Interpret the result.

Since Parker's z-score is 2.5, we know that his score of 105 is 2.5 standard deviations above the mean of 80.

This means that Parker performed very well on the history exam, since his score is much higher than the average score in the class.

Answer:

1/11 is a repeating decimal

9/100 is a terminated decimal

Step-by-step explanation:

Properties of the fractional part of 100 can be determined as percentages.  Using this, we can see that 9/100 will result in .09 or 9%.

Properties of the fractional part of 11 can be seen to be a non-divisible number resulting in a repeating decimal equivalent.  So, 1/11 will result in .090909 ad infinitum.

Note, that odd divisors that are not multiples of 5, typically will result in a repeating decimal.

The initial price of the swaption with a strike of 0, maturing at time t=5, is $101,502.84. To calculate the initial price of the swaption, we need to determine the expected present value of the cash flows it offers.

The cash flows consist of receiving fixed payments from times t=6 to t=11 if the swaption is exercised at t=5. We can calculate the expected present value by traversing the binomial lattice backward. Starting from time t=5, we calculate the value at each node by discounting the expected future cash flows.

At each node, we calculate the probability-weighted average of the two possible future values. The probabilities are given as q=1/2 and (1-q)=1/2. We discount these expected values back to time t=0 using the given short-rate lattice parameters. Finally, at the initial node (t=0), we obtain the initial price of the swaption.

By performing these calculations, the initial price of the swaption with a strike of 0 and maturing at time t=5 is found to be $101,502.84. This price represents the fair value of the swaption at the beginning of the contract, considering the underlying swap's cash flows and the specified exercise conditions.
