Approximately 95% of housing prices are between a low price of $164,000 and a high price of $192,000.

To determine the range of housing prices between which approximately 95% of prices fall, we can use the empirical rule, also known as the 68-95-99.7 rule. According to this rule, for a normal distribution:

- Approximately 68% of the data falls within one standard deviation of the mean.

- Approximately 95% of the data falls within two standard deviations of the mean.

- Approximately 99.7% of the data falls within three standard deviations of the mean.

In this case, the mean housing price is $178,000, and the standard deviation is $7,000. To find the low and high prices within which approximately 95% of the housing prices fall, we can apply the empirical rule.

First, we calculate one standard deviation:

Standard deviation = $7,000

Next, we calculate two standard deviations:

Two standard deviations = 2 * $7,000 = $14,000

To find the low price, we subtract two standard deviations from the mean:

Low price = $178,000 - $14,000 = $164,000

To find the high price, we add two standard deviations to the mean:

High price = $178,000 + $14,000 = $192,000

Therefore, approximately 95% of housing prices are between a low price of $164,000 and a high price of $192,000.

We have shown that statement 1 and statement 2 in Theorem 6.12 are equivalent, i.e., a linear transformation is invertible if and only if it is an isomorphism.

1. To prove that T : Mn,n → Mɲn is an isomorphism, we need to show that it is linear, injective (one-to-one), and surjective (onto).

- Linearity: Let A, B be matrices in Mn,n and let c be a scalar. We have T(cA + B) = (cA + B)B = cAB + BB = cT(A) + T(B), which shows that T is linear.

- Injectivity: Suppose T(A) = T(B) for some matrices A, B in Mn,n. Then AB = BB implies A = B by left multiplying both sides by B⁻¹, which shows that T is injective.

- Surjectivity: For any matrix C in Mɲn, we can find a matrix A = CB⁻¹, where B⁻¹ exists since B is invertible. Then T(A) = (CB⁻¹)B = CB⁻¹B = C, which shows that T is surjective.

Since T is linear, injective, and surjective, we conclude that T is an isomorphism.

2. To prove the equivalence between statement 1 and statement 2 in Theorem 6.12, we need to show that a linear transformation T is invertible if and only if it is an isomorphism.

- (=>) If T is invertible, then there exists an inverse transformation T⁻¹. Since T⁻¹ exists, it is a linear transformation. We can compose T and T⁻¹ to obtain the identity transformation, i.e., T∘T⁻¹ = T⁻¹∘T = I, where I is the identity transformation. This shows that T is one-to-one and onto, which means T is an isomorphism.

- (<=) If T is an isomorphism, then it is one-to-one and onto. Since T is onto, there exists an inverse transformation T⁻¹, which is also one-to-one. This shows that T is invertible.

Therefore, we have shown that statement 1 and statement 2 in Theorem 6.12 are equivalent, i.e., a linear transformation is invertible if and only if it is an isomorphism.

The area of the whole shape is approximately 391.98 m² (rounded to 1 decimal place).

To calculate the area of the shape formed by a right-angled triangle and a quarter circle, we can find the area of each component and then sum them together.

Area of the right-angled triangle:

The area of a triangle can be calculated using the formula A = (base × height) / 2. In this case, the base and height are the two sides of the right-angled triangle.

Area of the triangle = (22 m × 15 m) / 2 = 165 m²

Area of the quarter circle:

The formula to calculate the area of a quarter circle is A = (π × r²) / 4, where r is the radius of the quarter circle. In this case, the radius is half the length of the hypotenuse of the right-angled triangle, which is (22² + 15²)^(1/2) = 26.907 m.

Area of the quarter circle = (π × (26.907 m)²) / 4 = 226.98 m²

Total area of the shape:

To find the total area, we sum the area of the triangle and the area of the quarter circle.

Total area = Area of the triangle + Area of the quarter circle

Total area = 165 m² + 226.98 m² = 391.98 m²

Therefore, the area of the whole shape is approximately 391.98 m² (rounded to 1 decimal place).

a) (i) Gradient of the line: 2

(ii) Equation of the line: y = 2x + 2

(iii) x-intercept of the line: (-1, 0)

b) No, the line y = -3x + 3 does not intersect with the line y = 2x + 2.

c) Point of intersection: (16/15, -23/15)

a)

(i) Gradient of the line: The gradient of a straight line passing through the points (x1, y1) and (x2, y2) is given by the formula:

Gradient, m = (Change in y) / (Change in x) = (y2 - y1) / (x2 - x1)

Given the points (2, 6) and (-2, -2), we have:

x1 = 2, y1 = 6, x2 = -2, y2 = -2

So, the gradient of the line is:

Gradient = (y2 - y1) / (x2 - x1)

= (-2 - 6) / (-2 - 2)

= -8 / -4

= 2

(ii) Equation of the line: The general equation of a straight line in the form y = mx + c, where m is the gradient and c is the y-intercept.

To find the equation of the line, we use the point (2, 6) and the gradient found above.

Using the formula y = mx + c, we get:

6 = 2 * 2 + c

c = 2

Hence, the equation of the line is given by:

y = 2x + 2

(iii) x-intercept of the line: To find the x-intercept of the line, we substitute y = 0 in the equation of the line and solve for x.

0 = 2x + 2

x = -1

Therefore, the x-intercept of the line is (-1, 0).

b) Does the line y = -3x + 3 intersect with the line found in part (a)?

We know that the equation of the line found in part (a) is y = 2x + 2.

To check if the line y = -3x + 3 intersects with the line, we can equate the two equations:

2x + 2 = -3x + 3

Simplifying this equation, we get:

5x = 1

x = 1/5

Therefore, the point of intersection of the two lines is (x, y) = (1/5, -13/5).

c) Find the coordinates of the point where the lines with the following equations intersect:

9x - 2y = -4, -3x + 2y = 12.

To find the point of intersection of two lines, we need to solve the two equations simultaneously.

9x - 2y = -4 ...(1)

-3x + 2y = 12 ...(2)

We can eliminate y from the above two equations.

9x - 2y = -4

=> y = (9/2)x + 2

Substituting this value of y in equation (2), we get:

-3x + 2((9/2)x + 2) = 12

0 = 15x - 16

x = 16/15

Substituting this value of x in equation (1), we get:

y = -23/15

Therefore, the point of intersection of the two lines is (x, y) = (16/15, -23/15).

To solve the system of equations by elimination, we'll need to eliminate one of the variables.

[tex]Here's how to solve each system of equations:6x + 5y = 46x − 7y = −20[/tex]

To eliminate x, we will multiply the first equation by 7 and the second equation by 6.

[tex]This gives us:42x + 35y = 28636x − 42y = −120[/tex]

[tex]Now we will add the two equations together:78y = 166y = 166/78y = 83/39[/tex]

Now we will substitute the value of y into one of the original equations to find x.

[tex]We'll use the first equation:6x + 5y = 46x + 5(83/39) = 46x = (234/39) - (415/39)6x = -181/39x = (-181/39) ÷ 6x = -181/234[/tex]

[tex]Therefore, the solution of the system of equations is x = -181/234, y = 83/39(x+2)² + (y-2)² = 1y = - (x+2)² + 3[/tex]

To solve this system of equations, we will substitute y in the first equation by the right-hand side of the second equation.

[tex]This gives us:(x+2)² + (- (x+2)² + 3 - 2)² = 1(x+2)² + (-(x+2)² + 1)² = 1(x+2)² + (x+1)² = 1x² + 4x + 4 + x² + 2x + 1 = 1 2x² + 6x + 4 = 0 x² + 3x + 2 = 0  (Divide by 2) (x+2)(x+1) = 0x = -1, x = -2.[/tex]

[tex]We will now use the second equation to find the values of y:y = -(x+2)² + 3When x = -1: y = -(-1+2)² + 3 = -1When x = -2: y = -(-2+2)² + 3 = 3[/tex]

When calculating the electric field, we use the principle of superposition. Superposition is an idea in physics that says that when two waves pass through each other, the result is the sum of the amplitudes of the two waves. Superposition is also relevant to the addition of forces and fields, and can be used to find the net electric field produced by two charges. Therefore, the net electric field is the sum of the electric fields of the two charges. We can use Coulomb’s law to determine the electric field created by each point charge. Coulomb’s law states that the magnitude of the electric force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

The equation for Coulomb’s law is F=kQ1Q2/r².

where F is the force, Q1 and Q2 are the charges of the two particles, r is the distance between the two particles, and k is Coulomb’s constant.

To find the net electric field at the location (0,0.87) m, we have to use the distance formula to find the distance between the point charge and the location.

The distance between the point charge at the origin (0,0) and the point (0,0.87) m is d = 0.87 m

The distance between the point charge at (0.85,0) and the point (0,0.87) m is d = sqrt[(0.85 m)² + (0.87 m)²] = 1.204 m

Now, we can find the electric field due to each charge and add them up to get the net electric field.

Electric field due to the point charge at the origin:

kQ/r² = (9 x 10⁹ N·m²/C²)(6.73 x 10⁻⁹ C)/(0.87 m)² = 5.99 x 10⁴ N/C

Electric field due to the point charge at (0.85,0) m:

kQ/r² = (9 x 10⁹ N·m²/C²)(6.73 x 10⁻⁹ C)/(1.204 m)² = 3.52 x 10⁴ N/C

The net electric field is the vector sum of the electric fields due to each charge.

E = E1 + E2

E = (5.99 x 10⁴ N/C)i + (3.52 x 10⁴ N/C)j

E = (5.99 x 10⁴ N/C)i + (3.52 x 10⁴ N/C)k

E = sqrt[(5.99 x 10⁴ N/C)² + (3.52 x 10⁴ N/C)²]

E = 7.02 x 10⁴ N/C

Therefore, the magnitude of the net electric field at the location (0,0.87) m is 7.02 x 10⁴ N/C.

To differentiate the given functions, we will apply the rules of differentiation.

1) Differentiating y = 3x² + 4x³ + 6x² + 12x + 1:

Taking the derivative of each term separately:

dy/dx = d(3x²)/dx + d(4x³)/dx + d(6x²)/dx + d(12x)/dx + d(1)/dx

= 6x + 12x² + 12x + 12

2) Differentiating y = x²(4x + 7)³:

Using the product rule, we differentiate each term:

dy/dx = d(x²)/dx * (4x + 7)³ + x² * d((4x + 7)³)/dx

= 2x * (4x + 7)³ + x² * 3(4x + 7)² * 4

The probability of getting a number more than one when rolling a fair die once is 0.833.

When rolling a fair die, there are six possible outcomes: 1, 2, 3, 4, 5, and 6. Out of these outcomes, five of them (2, 3, 4, 5, and 6) are greater than one. To find the probability, we divide the number of favorable outcomes (getting a number greater than one) by the total number of possible outcomes. In this case, the probability is calculated as 5 favorable outcomes divided by 6 total outcomes, which gives us 0.833 when rounded to three decimal places.

In other words, since the die is fair, each outcome (1, 2, 3, 4, 5, and 6) has an equal chance of occurring, which is 1/6. Since we are interested in the probability of getting a number greater than one, which includes five outcomes out of the six, we sum up the probabilities of these five outcomes: 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6 = 0.833 (rounded to three decimal places).

The solution of the initial value problem is certain to exist for the interval t > -6.

The given initial value problem is a first-order linear ordinary differential equation. To determine the interval in which the solution is certain to exist, we need to consider the conditions that ensure the existence and uniqueness of solutions for such equations.

In this case, the coefficient of the derivative term is (t - 2), and the coefficient of the dependent variable y is ln(t + 6). These coefficients should be continuous and defined for all values of t within the interval of interest. Additionally, the initial condition y(-4) = 3 must also be considered.

By observing the given equation and the initial condition, we can deduce that the natural logarithm term ln(t + 6) is defined for t > -6. Since the coefficient (t - 2) is a polynomial, it is defined for all real values of t. Thus, the solution of the initial value problem is certain to exist for t > -6.

When solving initial value problems involving differential equations, it is important to consider the interval in which the solution exists. In this case, the interval t > -6 ensures that the natural logarithm term in the differential equation is defined for all values of t within that interval. It is crucial to examine the coefficients of the equation and ensure their continuity and definition within the interval of interest to guarantee the existence of a solution. Additionally, the given initial condition helps determine the specific values of t that satisfy the problem's conditions. By considering these factors, we can ascertain the interval in which the solution is certain to exist.

The largest possible domains of the given functions are:

(a) (fof)(x) = f(√x - 1), with the largest possible domain [0, ∞).

(b) (gof)(x) = { √x + 1 for x < 4, 1 for x ≥ 4}, with the largest possible domain [0, ∞).

(c) (gog)(x) = { x + 4 for x < -1, 1 for x ≥ -1}, with the largest possible domain (-∞, ∞).

(a) (fof)(x):

To find (fof)(x), we substitute f(x) into f(x) itself:

(fof)(x) = f(f(x))

Substituting f(x) = √x - 1 into f(f(x)), we get:

(fof)(x) = f(f(x)) = f(√x - 1)

The largest possible domain for (fof)(x) is determined by the domain of the inner function f(x), which is [0, ∞). Therefore, the largest possible domain for (fof)(x) is [0, ∞).

(b) (gof)(x):

To find (gof)(x), we substitute f(x) into g(x):

(gof)(x) = g(f(x))

Substituting f(x) = √x - 1 into g(x) = { x + 2 for x < 1, 1 for x ≥ 1}, we get:

(gof)(x) = g(f(x)) = { f(x) + 2 for f(x) < 1, 1 for f(x) ≥ 1}

Since f(x) = √x - 1, we have:

(gof)(x) = { √x - 1 + 2 for √x - 1 < 1, 1 for √x - 1 ≥ 1}

Simplifying the conditions for the piecewise function, we find:

(gof)(x) = { √x + 1 for x < 4, 1 for x ≥ 4}

The largest possible domain for (gof)(x) is determined by the domain of the inner function f(x), which is [0, ∞). Therefore, the largest possible domain for (gof)(x) is [0, ∞).

(c) (gog)(x):

To find (gog)(x), we substitute g(x) into g(x) itself:

(gog)(x) = g(g(x))

Substituting g(x) = { x + 2 for x < 1, 1 for x ≥ 1} into g(g(x)), we get:

(gog)(x) = g(g(x)) = g({ x + 2 for x < 1, 1 for x ≥ 1})

Simplifying the conditions for the piecewise function, we find:

(gog)(x) = { g(x) + 2 for g(x) < 1, 1 for g(x) ≥ 1}

Substituting the expression for g(x), we have:

(gog)(x) = { x + 2 + 2 for x + 2 < 1, 1 for x + 2 ≥ 1}

Simplifying the conditions, we find:

(gog)(x) = { x + 4 for x < -1, 1 for x ≥ -1}

The largest possible domain for (gog)(x) is determined by the domain of the inner function g(x), which is all real numbers. Therefore, the largest possible domain for (gog)(x) is (-∞, ∞).

Answer:

x² + 3x - 5

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

= 3x + 1 + x² - 6

= x² + 3x - 5

The simplified expression is 4x + 6y^3.

To simplify the expression 2x + x + x + 2y × 3y × y, we can apply the order of operations, which is also known as the PEMDAS rule (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Let's break it down step by step:

1. Simplify the expression within the parentheses: 2y × 3y × y.

  This can be rewritten as 2y * 3y * y = 2 * 3 * y * y * y = 6y^3.

2. Combine like terms by adding or subtracting coefficients of the same variable:

  2x + x + x = 4x.

3. Now we can rewrite the simplified expression by substituting the values we found:

  4x + 6y^3.

To rationalize the denominator of the expression 1/√6 + √5 - √11, we need to eliminate any square roots from the denominator.The rationalized form of the expression is (-√6 - 8 + √55) / 6.

First, let's rationalize the denominator of the fraction 1/√6. To do this, we can multiply both the numerator and denominator by the conjugate of √6, which is -√6. This gives us:

1/√6 = (1/√6) * (-√6)/(-√6) = -√6/6

Next, let's rationalize the denominator of the expression √5 - √11. To do this, we can multiply both the numerator and denominator by the conjugate of the expression, which is √5 + √11. This gives us:

(√5 - √11)/(√5 + √11) = [(√5 - √11) * (√5 - √11)] / [(√5 + √11) * (√5 - √11)]

= (5 - 2√55 + 11) / (5 - 11)

= (16 - 2√55) / (-6)

= (-8 + √55) / 3

Putting it all together, the expression 1/√6 + √5 - √11 can be rationalized as:

-√6/6 + (-8 + √55) / 3

Simplifying further, we get:

(-√6 - 8 + √55) / 6

Therefore, the rationalized form of the expression is (-√6 - 8 + √55) / 6.

Here are four crucial steps in the process of helping learners to build the relational skill that can help them to make sense of the numbers in an arithmetic pattern:

Look for the constant difference: In an arithmetic pattern, a constant number is added or subtracted each time to form consecutive terms. Encourage learners to identify this constant difference by subtracting any two adjacent numbers in the sequence. In this case, subtracting 4 from 7 gives 3, and subtracting 7 from 10 also gives 3. Therefore, the constant difference is 3.

Use the constant difference to predict future terms: Once the constant difference is identified, learners can use it to predict future terms in the sequence. For example, adding 3 to the last term (13) gives 16. This means that the next term in the sequence will be 16.

Check the prediction: Predicting the next term is not enough. Learners should also check their prediction by verifying it against the actual pattern. In this case, the next term in the sequence is indeed 16.

Generalize the pattern: Finally, encourage learners to generalize the pattern by expressing it in a formulaic way. In this case, the formula would be: nth term = 3n + 1. Here, n represents the position of the term in the sequence. For example, the fourth term (position n=4) would be 3(4) + 1 = 13.

By following these four crucial steps, learners can build their relational skills and be more efficient in making sense of arithmetic patterns like the one given.

The domain of h(g(x)) is the set of all real-numbers such that g(x) =[tex]x^{\frac{1}{2} }[/tex] ≥ 0 that is Dom(h(g(x))) = [0, ∞) for the function f(x)=√−x^2+11x−30 as a composition of a power function g(x) and a quadratic function h(x) .

Given that, f(x) = √(−x² + 11x − 30).

We have to decompose the function f(x) as a composition of a power function g(x) and a quadratic function h(x).

Let g(x) be a power function of the form g(x) = xⁿ.

Let h(x) be a quadratic function of the form :

h(x) = ax² + bx + c.So,

we have to find the values of n, a, b, and c such that f(x) = h(g(x)).

We have, g(x) = xⁿ and

h(x) = ax² + bx + c.

Then, h(g(x)) = a(xⁿ)² + b(xⁿ) + c

                     = ax² + bx + c.

Put x = 0.

We get,c = h(0)

Also, f(0) = h(g(0))

               = c

               = - 30

From the given function, f(x) = √(−x² + 11x − 30),

we see that it is the composition of a power function and a quadratic function, as shown below:

f(x) = √(-(x - 6)(x - 5))

     = √(-(x - 6))√(x - 5)

     = [tex](x-6)^{\frac{1}{2} }[/tex][tex](x-5)^{\frac{1}{2} }[/tex]

Therefore, g(x) = [tex]x^{\frac{1}{2} }[/tex]

and h(x) = (x - 6) + (x - 5)

             = 2x - 11.

So, f(x) = h(g(x))

m= 2([tex]x^{\frac{1}{2} }[/tex]) - 11

Therefore, h(g(x)) = 2([tex]x^{\frac{1}{2} }[/tex]) - 11

The domain of h(g(x)) is the set of all real numbers such that g(x) =[tex]x^{\frac{1}{2} }[/tex] ≥ 0.

Therefore, Dom(h(g(x))) = [0, ∞)

The set of solutions to the homogeneous system forms a linear subspace of R³, since it can be expressed as a linear combination of vectors with a parameter t.

To solve the homogeneous system of linear equations:

3x₁ - x₂ + x₃ = 0

-x₁ + 7x₂ - 2x₃ = 0

2x₁ + 6x₂ - x₃ = 0

We can rewrite the system in matrix form as AX = 0, where A is the coefficient matrix and X is the vector of variables:

A = [[3, -1, 1], [-1, 7, -2], [2, 6, -1]]

X = [x₁, x₂, x₃]

To find the solutions, we need to find the null space of the matrix A, which corresponds to the vectors X that satisfy AX = 0.

By performing Gaussian elimination on the augmented matrix [A|0] and row reducing it to reduced row-echelon form, we obtain:

[[1, 0, -1/3, 0], [0, 1, 1/3, 0], [0, 0, 0, 0]]

This shows that the system has infinitely many solutions and can be parameterized by setting x₃ = t, where t is a parameter. The solutions can then be expressed as:

x₁ = t/3

x₂ = -t/3

x₃ = t

Answer:

To solve the given system of equations using Gaussian elimination, let's rewrite the equations in matrix form:

```

[ 2 1 1 ] [ X ] [ 4 ]

[ 0 1 -0.1] * [ Y ] = [ 0.4]

[ 3 2 1 ] [ Z ] [ 2 ]

```

Performing Gaussian elimination:

1. Row 2 = Row 2 - 0.1 * Row 1

```

[ 2 1 1 ] [ X ] [ 4 ]

[ 0 0 0 ] * [ Y ] = [ 0 ]

[ 3 2 1 ] [ Z ] [ 2 ]

```

2. Row 3 = Row 3 - (3/2) * Row 1

```

[ 2 1 1 ] [ X ] [ 4 ]

[ 0 0 0 ] * [ Y ] = [ 0 ]

[ 0 1/2 -1/2] [ Z ] [ -2 ]

```

3. Row 3 = 2 * Row 3

```

[ 2 1 1 ] [ X ] [ 4 ]

[ 0 0 0 ] * [ Y ] = [ 0 ]

[ 0 1 -1 ] [ Z ] [ -4 ]

```

Now, we have reached an upper triangular form. Let's solve the system of equations:

From the third row, we have Z = -4.

Substituting Z = -4 into the second row, we have 0 * Y = 0, which implies that Y can take any value.

Finally, substituting Z = -4 and Y = k (where k is any arbitrary constant) into the first row, we can solve for X:

2X + 1k + 1 = 4

2X = 3 - k

X = (3 - k) / 2

Therefore, the solution to the system of equations is:

X = (3 - k) / 2

Y = k

Z = -4

Answer:

the answer is -109

Step-by-step explanation:

To factorize 4x2 + 9x - 13 completely, we will make use of splitting the middle term method. Let's start by multiplying the coefficient of the x2 term and the constant

term 4(-13) = -52. Our aim is to find two

numbers that multiply to give -52 and add up to 9. The numbers are +13 and

-4Therefore, 4x2 + 13x - 4x - 13 = ONow,

group the first two terms together and the last two terms together and factorize them out4x(x + 13/4) - 1(× + 13/4) = 0(x + 13/4)(4x - 1)

= OTherefore, the fully factorised form of 4x2 + 9x - 13 is (x + 13/4)(4x - 1).
