Transformation involves changing the coordinates of a point

The coordinates of the image of P is (9,13)

The coordinate of P is given as:

P = (-13,9)

The rule of reflecting the point over the line y = -x is represented as:

\((x,y) \to (y,-x)\)

So, we have:

\((-13,9) \to (9,13)\)

This means that:

\(P' = (9,13)\)

Hence, the coordinates of the image of P is (9,13)

For this case, we're specified that:

Forming hypotheses:

where \(\mu_0\) is the hypothesized population mean of the money his customer spends in his store.

The z-test statistic we get is:

\(z = \dfrac{\overline{x} - \mu_0}{\sigma/\sqrt{n}} = \dfrac{160 - 150}{30.20/\sqrt{40}} \approx 2.094\)

The test is single tailed, (right tailed).

The critical value of z at level of significance 0.025 is 1.96

Since we've got 2.904 > 1.96, so we reject the null hypothesis.

The Gibbs-Duhem equation relates the activity coefficients of the individual components in a mixture. It states that the activity coefficients are not independent of each other but are related by a differential equation.

In the case of a binary mixture (chemical A and chemical B), the Gibbs-Duhem relation can be written as:

x1 * (∂x1/∂lnγ1)T,P = x2 * (∂x2/∂lnγ2)T,P

Here, x1 and x2 represent the mole fractions of chemical A and chemical B, respectively. The activity coefficients for chemical A and chemical B are denoted as γ1 and γ2, respectively.

The equation shows that the change in mole fraction of one component (x1) with respect to the change in the logarithm of its activity coefficient (lnγ1) is proportional to the change in mole fraction of the other component (x2) with respect to the change in the logarithm of its activity coefficient (lnγ2).

This relationship helps us understand how changes in the activity coefficients of the components affect each other in a binary mixture. By studying this relationship, we can gain insights into the behavior of the mixture and make predictions about its properties.

For example, let's consider a mixture of ethanol (chemical A) and water (chemical B). If the activity coefficient of ethanol (γ1) decreases, the Gibbs-Duhem equation tells us that the mole fraction of ethanol (x1) will also decrease. Similarly, if the activity coefficient of water (γ2) increases, the mole fraction of water (x2) will increase.

Answer: D because this is a positive non-linear relationship.

Step-by-step explanation:

     First off, we will rule out answer options A and C because they both are negative and the problem says that the value is being increased.

     Next, we need to decide between answer option B (linear) or option D (exponential). Since the computer increases \(\frac{1}{3}\) of it's value every year, this is an exponential growth.

     For example, let us say the computer is currently worth $10. Next year it will be worth $13.33 (10 * 1.3333) and the year after that it will be worth $17.77 (13.33 * 1.333). This is not a linear relationship.

When the ride accelerates upwards at 3.0 m/s², the scale will show a weight greater than 150 lbs. When the ride accelerates downwards at 3.0 m/s², the scale will show a weight less than 150 lbs. When the ride moves at a constant velocity, the scale will show a weight of 150 lbs.

When the ride accelerates upwards at 3.0 m/s², the scale will show a weight greater than 150 lbs. This is due to the additional force exerted on your body as the ride pushes you upwards. The scale measures the normal force acting on you, which is equal to your weight plus the additional force from the acceleration. As a result, the scale will display a weight higher than your actual weight of 150 lbs.

On the other hand, when the ride accelerates downwards at 3.0 m/s², the scale will show a weight less than 150 lbs. In this case, the acceleration is in the opposite direction to the gravitational force, causing a decrease in the normal force. The scale measures the normal force, which is equal to your weight minus the force due to acceleration. Therefore, the scale will display a weight lower than 150 lbs.

When the ride moves at a constant velocity, the scale will show a weight of 150 lbs. At constant velocity, there is no acceleration acting on your body. The scale measures the normal force, which is equal to your weight. Since there are no additional forces from acceleration, the scale will display your actual weight of 150 lbs.

The sequence of transformations that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral GHIJ is a 90-degree counterclockwise rotation around point A (Option B) followed by a reflection across the y axis and a translation 20 units down (Option B)

A transformation is a general term which indicates four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. There are 4 types of transformation: translation, rotation, reflection, and enlargement.

Consider the quadrilateral ABCD has vertices with coordinates A(15,10) B(15,20) C(20, 15) and D(20, 5)

When rotating a point 90 degrees counterclockwise about the point, point A remains the same. Hence A(15,10) →A'(15,10);  B(15,20)→B'(5,10); C(20,15)→C'(10,15); D(20,5)→D'(20,15).

A reflection across the y axis is given as  (x,y)→(-x,y). Hence, A'(15,10)→A''(-15,10); B'(5,10)→B''(-5,10); C'(10,15)→C''(-10,15); D'(20,15)→D''(-20,15).

When translation of 20 units down occurs, (x.y) → (x, y-20). Hence, A''(-15,10)→G(-15,-10); B''(-5,10)→H(-5,-10); C''(-10,15)→I(-10,-5); D''(-20,15)→J(-20,-5).

Answer:

The large box weighs 18.75 and the small box weights 15.75

Step-by-step explanation:

We are looking to find 2 variables so we will need two equations.

Let l = the large box weight

Let s = the small box weight

7l + 9s + 273                   5l +3s = 141

I want to add these two equations together and have one of the variables be eliminated.  The way both equations are written now, neither variable will drop out.  I see that 9 is a multiple of 3.  If I multiply the second equation all the way through by - 3, the s variable will be eliminated.

-3(5l +3s) -3(141)  Multiple everything by -3

-15l -9s = -423  Now I will add this to the original equation 7l + 9s = 273

7l + 9s = 273

-8l = -150  Divide both sides by -8

l = 18.75  This is the weight of the large box.

Plug in 18.75 to either of the ordinal equations to find the weight of the small box.

5l + 3s = 141

5(18.75) + 3s = 141  Distribute the 5

93.75 + 3s = 141  Subtract 93.75 from both sides

3s = 47.25  Divide both sides by 3

s = 15.75

Check:

Plug in 15.75 for s and 18.75 for l into both of the original equation to see if they equal.

7l + 9s = 273

7(18.75) + 9(15.75) =273

131.25 + 141.75 = 273  Checks

5l + 3s = 141

5(18.75) + 3(15.75) = 141

93.75 + 47.25 = 141

141 = 141 Checks

The number of the solutions of the equations are 2 that are (1, 0) and (-3, 4).

The equations are given below.

y = x² + x − 2  ...1

y = – x + 1       ...2

From equations 1 and 2, we have

x² + x − 2 = – x + 1

x² + 2x − 3 = 0

Then the factor of the equation will be

x² + 3x – x − 3 = 0

    (x + 3)(x – 1) = 0

                     x = 1, –3

Then  the value of y will be

At x = 1, we have

y = -1 + 1

y = 0

At x = -3, we have

y = -(-3) + 1

y = 4

Then the number of the solutions of the equations are 2 that are (1, 0) and (-3, 4).

The population proportion of cars that take some damage exceeds the park’s claim.

Given that:

Population proportion of all cars that have some damage from an animal after the safari is:

p = 0.65

Sample size, n = 20

\(\hat{p}\) = 18/20 = 0.9

The hypothesis can be defined as:

H₀ : p ≤ 0.65

H₁ : p > 0.65

Now, the z-value corresponds to α = 0.05 is z = 1.645.

So the critical value of z = 1.645

Now, the test statistic is:

z = \(\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n} } }\)

  = \(\frac{0.9-0.65}{\sqrt{\frac{0.65(1-0.65)}{20} } }\)

Here the test statistic, z, is greater than the critical value of z.
