a) The relation is reflexive, symmetric, and transitive.

b) The relation is not reflexive, symmetric, or transitive.

a) For each watermelon x, x is related to x because the measured weight of x is at least the measured weight of x. Therefore, the relation is reflexive.

For each watermelon x and y, if x is related to y (meaning the measured weight of x is at least the measured weight of y), then y is also related to x (meaning the measured weight of y is at least the measured weight of x). Therefore, the relation is symmetric.

For each watermelon x, y, and z, if x is related to y (meaning the measured weight of x is at least the measured weight of y) and y is related to z (meaning the measured weight of y is at least the measured weight of z), then x is related to z (meaning the measured weight of x is at least the measured weight of z). Therefore, the relation is transitive.

b) For each watermelon x, x is not related to x because no two watermelons have the same measured weight. Therefore, the relation is not reflexive.

For each watermelon x and y, if x is related to y (meaning the measured weight of x is at least the measured weight of y), then y is not related to x (meaning the measured weight of y is not at least the measured weight of x).

Therefore, the relation is not symmetric. For each watermelon x, y, and z, if x is related to y (meaning the measured weight of x is at least the measured weight of y) and y is related to z (meaning the measured weight of y is at least the measured weight of z), then x is not related to z (meaning the measured weight of x is not at least the measured weight of z).

Answer:

y = -7 and x = -36

Step-by-step explanation:

x - 4y = -8

5y - 1 = x

→ Substitute 5y - 1 into x - 4y = -8

5y - 1 - 4y = -8

→ Simplify

y - 1 = -8

→ Add 1 to both sides

y = -7

→ Substitute y = -7 into 5y - 1

( 5 × -7 ) - 1 = -36

Answer:

The solution is (-36, -7)

Step-by-step explanation:

Since 5y - 1 = x, we can replace x in the first equation by 5y - 1:

5y - 1 - 4y = -8

Collecting like terms, we get:

y = -7

If y = 7, then by the second equation x = 5(-7) - 1 = -36

The solution is (-36, -7)

The general solution of the damped spring-mass system with the given parameters is y(t) = e^(-t/2) [c1cos((√7/2)t) + c2sin((√7/2)t)]. By applying the initial conditions y(0) = 1 and y'(0) = 0, the specific solution can be obtained as y(t) = (2/7)e^(-t/2)cos((√7/2)t) + (3/7)e^(-t/2)sin((√7/2)t).

The equation for the damped spring-mass system can be expressed as my'' + cy' + ky = 0, where m is the mass, c is the damping coefficient, and k is the spring constant. In this case, m = 1 kg, c = 3 kg/s, and k = 2 kg/[tex]s^2[/tex].

To find the general solution, we assume a solution of the form y(t) = e^(rt). By substituting this into the equation and solving for r, we get [tex]r^2[/tex] + 3r + 2 = 0. Solving this quadratic equation gives us the roots r1 = -2 and r2 = -1.

The general solution is then given by y(t) = c1e^(-2t) + c2e^(-t). However, since we have a damped system, the general solution can be rewritten as y(t) = e^(-t/2) [c1cos((√7/2)t) + c2sin((√7/2)t)], where √7/2 = √(3/4).

By applying the initial conditions y(0) = 1 and y'(0) = 0, we can solve for the coefficients c1 and c2. The specific solution is obtained as y(t) = (2/7)e^(-t/2)cos((√7/2)t) + (3/7)e^(-t/2)sin((√7/2)t). This satisfies the given initial value problem.

Step-by-step explanation:

Based on the ratios of gas mileage of Jesse's motorcycle to that of his car, 2x and x respectively, we have found out that the gas mileage of Jesse’s motorcycle on the highway is 56 mpg.

To solve the problem of finding out the gas mileage of Jesse’s motorcycle on the highway, it is necessary to use ratios. The first ratio is based on the gas mileage of Jesse’s car on the highway which is 28 mpg, then the ratio for his motorcycle is set as 2x, where x is the mileage per gallon of Jesse’s car, 28.

Therefore, the second ratio is 2x. Then we can equate these ratios in order to solve the problem. This can be done as follows: 2x/28 = y/1, where y represents the gas mileage of Jesse’s motorcycle on the highway.

Solving for y yields the following:

2x/28 = y/1

2x * 1 = 28 * y

2x = 28y

2x/2 = 28y/2

x = 14y

So the gas mileage of Jesse’s motorcycle on the highway is 14 times the mileage of his car. Therefore, to find out the gas mileage of his motorcycle on the highway, we need to multiply 28 by 2 and then divide the result by 1 which is equal to 56. Therefore, the gas mileage of Jesse’s motorcycle on the highway is 56 mpg.

In conclusion, based on the ratios of gas mileage of Jesse's motorcycle to that of his car, 2x and x respectively, we have found out that the gas mileage of Jesse’s motorcycle on the highway is 56 mpg. This has been calculated using the equation 2x/28 = y/1, where y is the gas mileage of Jesse’s motorcycle on the highway.

Step-by-step explanation:

Serena started with approximately $173.33 money.

Let's denote the initial amount of money Serena had as S and the initial amount of money Visala had as V.

According to the problem, their combined total was $180, so we have the equation S + V = 180.

After Serena gave Visala $20, Serena's remaining amount became S - 20, and Visala's amount became V + 20.

Visala then gave Serena a quarter of the money she had, which is (V + 20)/4. After this transaction, Serena's total amount became S - 20 + (V + 20)/4, and Visala's total amount became V + 20 - (V + 20)/4.

It is given that after these transactions, they each had the same amount. Therefore, we can set up the equation:

S - 20 + (V + 20)/4 = V + 20 - (V + 20)/4.

Let's simplify and solve for S:

4S - 80 + V + 20 = 4V + 80 - V - 20.

Combining like terms:

4S + V = 3V + 160.

Substituting the value of S + V = 180 from the first equation:

4S + V = 3(180) + 160,

4S + V = 540 + 160,

4S + V = 700.

Now, we have two equations:

S + V = 180,

4S + V = 700.

Subtracting the first equation from the second equation:

4S + V - (S + V) = 700 - 180,

3S = 520,

S = 520/3 ≈ 173.33.

In the Italian class survey, 50 students were asked about how they listen to music. A Venn diagram was used to represent the information. Five students liked none of the types of music, 37 students liked exactly two types of music, and 39 students liked at least two types of music.

(a) The information can be represented in a Venn diagram as follows:

In the diagram, S represents the number of students who listen to Spotify, P represents the number of students who listen to Pandora, and R represents the number of students who listen to the radio. The overlapping regions show the number of students who listen to multiple platforms.

         ___________

        |           |

        |    S      |

        |___________|

        |           |

   R    |    SP     |   P

        |___________|

        |           |

        |     RP    |

        |___________|

(b) To determine the number of students who liked none of these types of music, we need to find the students who did not fall into any of the three categories. This can be calculated by subtracting the total number of students who liked at least one type of music from the total number of students surveyed.

Total number of students surveyed = 50

Students who liked at least one type of music = S + P + R - (SP + SR + PR) + SPR

Substituting the given values:

Students who liked at least one type of music = 34 + 30 + 18 - (22 + 13 + 4) + 2 = 45

Students who liked none of these types of music = Total number of students surveyed - Students who liked at least one type of music

Students who liked none of these types of music = 50 - 45 = 5

Therefore, 5 students liked none of these types of music.

(c) To find the number of students who liked exactly two types of music, we need to calculate the sum of the students in the overlapping regions of the Venn diagram.

Students who liked exactly two types of music = SP + SR + PR - (SPR)

Substituting the given values:

Students who liked exactly two types of music = 22 + 13 + 4 - 2 = 37

Therefore, 37 students liked exactly two types of music.

(d) To determine the number of students who liked at least two types of music, we need to add the students who liked exactly two types of music to the number of students who liked all three types of music.

Students who liked at least two types of music = Students who liked exactly two types of music + Students who liked all three types of music

Students who liked at least two types of music = 37 + 2 = 39

Therefore, 39 students liked at least two types of music.

Answer:

(a) The mortgage amount she will borrow is $180,400

(b) Yes she can

(c) Her monthly payment will be approximately $914.06

(d) Her total repayment is approximately $329,061.6

(e) The amount of interest is approximately $148,661.6

Step-by-step explanation:

The details of the transactions are;

The gross annual income Victoria earns = $124,482

The cost price of the home she is buying, C = $225,500

The amount she is making as down payment = 20%

The duration the loan she id financing the rest with, t = 30-years

The interest rate on the loan, r = 4.5%

(a) The mortgage amount she will borrow, 'P', is the cost of the home less the down payment

The down payment = 20% of the cost of the home

∴ The down payment = (20/100) × $225,500 = $45,100

∴ P = $225,500 - $45,100 = $180,400

The mortgage amount she will borrow, P = $180,400

(b) Using the 2× to 2.5× gross income rule, we have;

2 × her annual income = 2 × 124,482 = 248,964

∴ 2 × her annual income > The mortgage = 180,400

She can afford the mortgage

(c) The monthly fixed payment for the mortgage is given as follows;

   [tex]M = P \times \dfrac{r}{n} \times \dfrac{\left(1+ \dfrac{r}{n} \right)^{n \cdot t}}{\left[\left(1 + \dfrac{r}{n} \right)^{n\cdot t} - 1\right]}[/tex]

Where;

n = The number of periods per year = 12 monthly periods per year

180,400*0.045*(1 + 0.045)^(30)/((1 + 0.045)^(30) - 1)

[tex]M = 180,400 \times \dfrac{0.045 }{12} \times \dfrac{\left(1+\dfrac{0.045 }{12}\right)^{30 \times 12}}{\left[\left(1 + \dfrac{0.045 }{12}\right)^{30 \times 12} - 1\right]} \approx 914.060298926[/tex]

Her monthly payment will be M ≈ $914.06

(d) The total repayment is given as follows;

n × t × M

∴ 12 × 30 × 914.06 = 329061.6

The total payment for the house = $329,061.6

(e) The amount of interest = The total payment - The principal loan amount

∴ The amount of interest = $329061.6 - $180,400 = $148,661.6

Step-by-step explanation:

The coordinates satisfy the equation x^2 + y^2 = 1. In this specific problem, we found that P(x, y) = (3 * sqrt(10)) / 10 , - (sqrt(10)) / 10.

To solve this problem, we need to recall some basic trigonometry concepts related to the unit circle. The unit circle is a circle of radius 1 centered at the origin of a coordinate plane. Any point on the unit circle can be represented by its coordinates (x, y), where x and y are the horizontal and vertical distances from the origin, respectively.

Since the given problem tells us that the x-coordinate of P is positive, we know that x > 0. Additionally, we are given that the y-coordinate of P is -(square root 10)/10. We can use this information to solve for x.

From the Pythagorean theorem, we know that for any point (x, y) on the unit circle, x^2 + y^2 = 1. Substituting y = -(square root 10)/10, we get:

x^2 + ((-sqrt(10))/10)^2 = 1

Simplifying this expression, we get:

x^2 + 10/100 = 1

x^2 = 90/100

x = sqrt(90)/10

Since we know that x is positive, we can simplify this expression further by factoring out a square root:

x = (sqrt(9) * sqrt(10)) / 10

x = (3 * sqrt(10)) / 10

Therefore, the coordinates of point P are:

P(x, y) = (3 * sqrt(10)) / 10 , - (sqrt(10)) / 10

We can check our answer by verifying that these coordinates satisfy the equation x^2 + y^2 = 1:

(3 * sqrt(10) / 10)^2 + (-sqrt(10) / 10)^2 = 9/100 + 10/100 = 1/10

Simplifying this expression, we get:

1/10 = 1/10

This confirms that our answer is correct and that P lies on the unit circle.

In summary, to find the coordinates of a point P on the unit circle given its y-coordinate and the fact that its x-coordinate is positive, we can use the Pythagorean theorem to solve for the x-coordinate. We then check our answer by verifying that the coordinates satisfy the equation x^2 + y^2 = 1. In this specific problem, we found that P(x, y) = (3 * sqrt(10)) / 10 , - (sqrt(10)) / 10.

1. The standard error for the sampling distribution of proportion is approximately 0.0478.

The standard error for the sampling distribution of proportion can be calculated using the formula:

SE = sqrt((p * (1 - p)) / n)

where p is the population proportion and n is the sample size. In this case, p = 0.33 and n = 100.

Plugging in the values, we have:

SE = sqrt((0.33 * (1 - 0.33)) / 100) ≈ 0.0478

Therefore, the standard error for the sampling distribution of proportion is approximately 0.0478.

2. The probability that between 26% and 35% of the customers have read at least one book from the Henry Potter series is approximately 0.7789.

To calculate the probability, we need to find the z-scores corresponding to the percentages 26% and 35% and then find the area between these two z-scores under the standard normal distribution curve.

First, we calculate the z-scores using the formula:

z = (x - p) / sqrt((p * (1 - p)) / n)

where x is the given percentage, p is the population proportion, and n is the sample size.

For x = 26%:

z = (0.26 - 0.33) / sqrt((0.33 * (1 - 0.33)) / 100) ≈ -1.232

For x = 35%:

z = (0.35 - 0.33) / sqrt((0.33 * (1 - 0.33)) / 100) ≈ 0.522

Using a standard normal distribution table or calculator, we can find the area between -1.232 and 0.522, which is the probability that between 26% and 35% of the customers have read at least one book from the Henry Potter series. The approximate probability is 0.7789.

Therefore, the probability that between 26% and 35% of the customers have read at least one book from the Henry Potter series is approximately 0.7789.
