Step-by-step explanation:

The solution of the equation is (-2, 3) and to eliminate x we have to multiply equation(i) by 3 and multiply equation(ii) by 4.

System of equation can be solved using different method such as elimination method, substitution method and graphical method,

Let's use elimination method to solve the system of equation.

Therefore,

4x + 5y = 7

3x - 2y = - 12

Multiply equation(i) by 3 and equation(ii) by 4 to eliminate x.

Hence,

12x + 15y = 21

12x - 8y = - 48

Subtract the equations

23y = 69

y = 69 / 23

y = 3

Hence,

4x = 7 - 5y

4x = 7 - 5(3)

4x = 7 - 15

4x = -8

x = -8 / 4

x = -2

Therefore, the solution is (-2, 3)

The actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.

The margin of error in the report stating that a 10-year-old American child spends an average of 20.02 to 25.36 minutes playing outdoors per day can be calculated by subtracting the lower value from the higher value and dividing by 2. In this case, the margin of error is :

To find the margin of error, we need to calculate the halfway point between these two values.
(25.36 - 20.02) / 2 = 2.67

Therefore, the margin of error is approximately 2.67 minutes. This means that the actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.

Thus, the actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

a) Probability between 75.0 and 90.0: P(75.0 < x < 90.0) ≈ 0.4030.

b) Probability of 75.0 or less: P(x ≤ 75.0) ≈ 0.3581.

c) Probability between 55.0 and 70.0: P(55.0 < x < 70.0) ≈ 0.2017.

To calculate the probabilities, use the standard normal distribution calculator.

a) Probability of a value between 75.0 and 90.0,

z₁ = (75.0 - 80.0) / 14.0

   = -0.3571

z₂ = (90.0 - 80.0) / 14.0

   = 0.7143

Using the standard normal distribution calculator, find the probabilities,

P(z < -0.3571) = 0.3581

P(z < 0.7143) = 0.7611

P(75.0 < x < 90.0)

= P(z₁) - P(z₂)

= 0.3581 - 0.7611

≈ -0.4030

However, probabilities cannot be negative, so we round it to 4 decimal places:

P(75.0 < x < 90.0) ≈ 0.4030

b) Probability of a value of 75.0 or less,

z = (75.0 - 80.0) / 14.0

  = -0.3571

P(z < -0.3571) = 0.3581

P(x ≤ 75.0) ≈ P(z < -0.3571)

                 = 0.3581

c) Probability of a value between 55.0 and 70.0,

z₁= (55.0 - 80.0) / 14.0

  = -1.7857

z₂ = (70.0 - 80.0) / 14.0

    = -0.7143

P(z < -1.7857) = 0.0372

P(z < -0.7143) = 0.2389

P(55.0 < x < 70.0)

= P(z₁) - P(z₂)

= 0.0372 - 0.2389

≈ -0.2017

Again, round it to 4 decimal places,

P(55.0 < x < 70.0) ≈ 0.2017

Therefore, the required probabilities are,

a) P(75.0 < x < 90.0) ≈ 0.4030.

b) P(x ≤ 75.0) ≈ 0.3581.

c) P(55.0 < x < 70.0) ≈ 0.2017.

Answer:

∠AMC = 76°

Step-by-step explanation:

1) Because ∠YMC = 170°, you need to add 5x+19 (∠YMA) and 5x+1 (∠AMC) to equal the length of ∠YMC:

170 = 5x + 19 + 5x + 1

2) Combine like terms:

170 = 10x + 20

3) Subtract 20 from both sides:

150 = 10x

4) Divide by 10:

x =15

5) Replace x in ∠AMC with 15:

5(15) + 1

6) Multiply:

∠AMC = 76°

The measure of ∠AMC is 76°.

Given that, m∠YMC=170°, m∠YMA=(5x+19)° and m∠AMC=(5x+1)°.

We need to find the value of m∠AMC.

The two angles are said to be adjacent angles when they share the common vertex and side. The endpoint of the rays, forming the sides of an angle, is called the vertex of an angle. Adjacent angles can be complementary angles or supplementary angles when they share the common vertex and side.

Now, m∠YMA+m∠AMC=m∠YMC

⇒(5x+19)° + (5x+1)°=170°

⇒10x+20=170

⇒10x=150

⇒x=15

So, m∠AMC=5x+1=76°

Therefore, the measure of ∠AMC is 76°.

The inequality that represents the years before emoji were introduced is y < 1997.

To describe the years before emoji were introduced, we can use the inequality:

y < 1997

In this inequality, "y" represents the number of years before 1997. The symbol "<" means "less than," indicating that "y" should be a year prior to 1997 for the statement to be true.

This inequality restricts the possible values of "y" to any year before 1997.

For example, if we substitute "y" with the value 1990, the inequality would be true:

1990 < 1997

This statement is true because 1990 is indeed less than 1997. However, if we substitute "y" with a value after 1997, such as 2000, the inequality would be false:

2000 < 1997

This statement is false because 2000 is not less than 1997.

Therefore, any value of "y" that satisfies the condition y < 1997 represents a year before emoji were introduced.

Step-by-step explanation:

The equation\(2^2 = 3^2\) does not define any of the given shapes, as it is simply a false statement. The equation \(y^{2/2 }= x^{2/2\) does define a hyperbolic paraboloid.

On the other hand, the equation \(y^{2/2 }= x^{2/2\) defines a hyperbolic paraboloid. A hyperbolic paraboloid is a three-dimensional surface that has a saddle-like shape, with two opposing parabolic curves that cross each other. It is also known as a "saddle surface" due to its shape.

The equation \(y^{2/2 }= x^{2/2\) can be rewritten as \(y^{2/2 }= x^{2/2\), which is in the form of a hyperbolic paraboloid equation. This surface can be obtained by taking a parabolic curve and sweeping it along a straight line in a perpendicular direction. This creates a surface with a hyperbolic cross-section in one direction and a parabolic cross-section in the other direction.

Hyperbolic paraboloids have a wide range of applications in architecture, engineering, and design. They are often used in the construction of roofs, shells, and other structures that require strong and lightweight materials. They can also be used to create interesting and unique shapes in art and sculpture.

The equation 2x^2 = 3y^2 does not define any of the given three-dimensional shapes.

This is because it does not contain a z variable, which is necessary to define these shapes in three dimensions. Therefore, the equation cannot represent any of the given shapes.

On the other hand, the equation y^2 = 2x defines a hyperbolic paraboloid. This is a three-dimensional shape that resembles a saddle. It is formed by taking a hyperbola and rotating it around its axis. In this case, the hyperbola is oriented along the x-axis, and the parabolic cross-sections occur in the y-direction.

The equation can be rewritten as y^2 = 2(x - 0)^2, which is the standard form of a hyperbolic paraboloid. This equation can be graphed in a three-dimensional coordinate system, with the x-axis and y-axis forming the base and the z-axis representing the height of the surface above the base.

Answer: y = 2(x + 2)² - 5

Step-by-step explanation:

          We are going to use the completing the square method to transform this quadratic equation from standard form to vertex form.

Given:

     y = 2x² + 8x + 3

Factor the 2 out of the first two terms:

     y = 2(x² + 4x) + 3

Add and subtract \(\frac{b}{2} ^2\):

     y = 2(x² + 4x + 4 - 4) + 3

Distribute the 2 into -4 and combine with the 3:

     y = 2(x² + 4x + 4) - 5

Factor (x² + 4x + 4):

     y = 2(x + 2)² - 5

The probability that more than 12 particles occur in the area of a disk under the study is 0.20844.

The number of particles follows a Poisson Distribution.

A Poisson Distribution over a variable X, having a mean λ, has a probability for a random variable x as  \(P(X = x) = e^{-\lambda} \frac{\lambda^{x}}{x!}\) .

In the question, x = 12.

λ = 100*0.1 = 10.

To find : P(X > 12)

P(X > 12) = 1 - P(X ≤ 12) = 1 - poissoncdf(10,12)

As to find the probability of a Poisson Distribution P(X ≤ x), for a mean = λ, we use the calculator function poissoncdf(λ,x).

Therefore, P(X > 12) = 1 - 0.79156 = 0.20844.

Therefore, the probability that more than 12 particles occur in the area of a disk under the study is 0.20844.

(ii) Maximize Z' = 5a + 6b + 2c Subject to: 3a + 2b + c ≤ 1 4a + 6b + c ≤ 2 a + b ≤ 0 a, b, c ≥ 0.

In the first problem, we have a maximization problem with three variables (x, y, z) and two constraints. The dual formulation involves minimizing a new objective function with two variables (a, b) and four constraints. The coefficients of the variables and the constraints are transformed according to the rules of duality.

The primal problem is:

Maximize Z = 3x + 4y + 5z

Subject to:

x + 2y + z ≤ 10

7x + 3y + 9z ≤ 12

x, y, z ≥ 0

To find the dual, we introduce the dual variables a and b for the constraints:

Minimize Z' = 10a + 12b

Subject to:

a + 7b ≥ 3

2a + 3b ≥ 4

a + 9b ≥ 5

a, b ≥ 0

In the second problem, we have a minimization problem with two variables (y1, y2) and three constraints. The dual formulation requires maximizing a new objective function with three variables (a, b, c) and four constraints. Again, the coefficients and constraints are transformed accordingly.

The primal problem is:

Minimize Z = y1 + 2y2

Subject to:

3y1 + 4y2 > 5

2y1 + 6y2 ≥ 6

y1 + y2 ≥ 2

To find the dual, we introduce the dual variables a, b, and c for the constraints:

Maximize Z' = 5a + 6b + 2c

Subject to:

3a + 2b + c ≤ 1

4a + 6b + c ≤ 2

a + b ≤ 0

a, b, c ≥ 0

The duality principle in linear programming allows us to find a lower bound (for maximization) or an upper bound (for minimization) on the optimal objective value by solving the dual problem. It provides useful insights into the relationships between the primal and dual variables, as well as the economic interpretation of the problem.

The formula for the volume of a cone is:

V = (1/3)πr²h

where r is the radius of the base, h is the height of the cone, and π is pi.

In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:

h² = s² - r²

h² = 17² - 8²

h² = 225

h = 15

Now that we have the height, we can plug in the values for r and h into the formula for the volume:

V = (1/3)π(8²)(15)

V = (1/3)π(64)(15)

V = (1/3)(960π)

V = 320π

Answer (assuming that the equation can be written in point-slope form):

\(y-8 = -5(x+\frac{1}{2} )\)

Step-by-step explanation:

Use the point-slope formula, \(y-y_1 = m (x-x_1)\) , to write the equation of the line in point-slope form. Substitute values for the \(m\), \(x_1\), and \(y_1\) in the formula.

Since \(m\) represents the slope, substitute -5 in its place. Since \(x_1\) and \(y_1\) represent the x and y values of one point the line intersects, substitute the x and y values of (-0.5, 8) into the formula as well. Remember that we can convert -0.5 to a fraction: \(-\frac{1}{2}\). So, substitute \(-\frac{1}{2}\) for \(x_1\) and 8 for \(y_1\). This gives the following answer and equation:

The problem with reporting the results of the survey as 'adding weight to a car is what makes it consume more fuel'.

It implies causality based solely on the observed correlation between car weight and fuel consumption.

Correlation does not imply causation.

Meaning that the fact that two variables are correlated does not necessarily mean that one causes the other.

It is possible that there is a third variable that causes both car weight and fuel consumption to increase.

Or that the correlation is purely coincidental.

It is important to be cautious about interpreting correlation as causation.
