The roster method of the set X ∪ (Y ∩ Z) = {p, q, r, s, 21, 22, 23, 25}
How to find sets using roster method?The roster method is defined as a way to show the elements of a set by listing the elements inside of brackets.
A typical example of the roster method is to write the set of numbers from 1 to 5 as {1, 2, 3, 4, 5}.
Therefore,
X = {p, q, r, 21, 22, 23}
Y = {q, s, t, 21, 23, 25}
Z = {q, s, 22, 23, 25}
Therefore, let's find X ∪ (Y ∩ Z) as follows:
(Y ∩ Z) = {q, s, 23, 25}
X = {p, q, r, 21, 22, 23}
Therefore,
X ∪ (Y ∩ Z) = {p, q, r, s, 21, 22, 23, 25}

The vertices of a quadrilateral in the coordinate plane are known. How can the perimeter of the figure be found?
Use the distance formula to find the length of each side, and then add the lengths.
Use the slope formula to find the slope of each of side, and then determine if the opposite sides are parallel.
Use the slope formula to find the slope of each of side, and then determine if the consecutive sides are perpendicular.
Use the distance formula to find the length of the sides, and then multiply two of the side lengths.
Answer:
(a) Use the distance formula to find the length of each side, and then add the lengths.
Step-by-step explanation:
You want to know a suitable strategy for finding the perimeter of a quadrilateral when the coordinates of its vertices are known.
PerimeterThe perimeter of a figure is the sum of its side lengths. When the coordinates of the ends of a side segment are known, the length of that segment can be found using the distance formula.
This should make it obvious that a suitable strategy for finding the perimeter is to find the length of each side and add the lengths.
__
Additional comment
The slope is irrelevant when the perimeter is what you want.
The slope can be relevant if you're trying to prove a quadrilateral is a parallelogram or rectangle (or something else with parallel sides). (There are easier ways than using the slope.)
Multiplying side lengths will be relevant if you want the area of a rectangle. The product has no relation to the perimeter.

A car is traveling at a rate of 30 meters per second. What is the car's rate in kilometers per hour? How many kilometers will the car travel in 5 hours? Do not
round your answers.
The speed of the car is 108 kilometers per hour and the distance covered in 5 hours is 540 kilometers.
What is the speed of the car in kilometers per hour and distance covered after 5 hours?Speed is simply referred to as distance traveled per unit time.
It is expressed as;
Speed = Distance ÷ time.
Given that the car is traveling at a rate of 30 meters per second.
First, convert the car's speed from meters per second to kilometers per hour using the conversion factor.
1 kilometer = 1000 meters
1 hour = 3600 seconds
Hence;
Speed = 30m/s = ( 30 × 3600/1000 )kmh
Speed = 108 kmh
Next, the distance covered in 5 hours will be:
Speed = Distance / time
Distance = speed × time
Distance = 108 kmh × 5 h
Distance = 540 km
Therefore, the disatnce covered is 540 kilometers.

(b) The theoretical probability of rolling an odd number is 1/2.
(c)The true statement is:
With a small number of rolls, it is not surprising when the experimental probability is much greater than the theoretical probability.
How to compute the experimental probability of rolling an odd number?Probability is the likelihood of a desired event happening.
Experimental probability is a probability that relies mainly on a series of experiments.
Theoretical probability is the theory behind probability. To find the probability of an event, an experiment is not required. Instead, we should know about the situation to find the probability of an event occurring.
We have:
Kala rolled a number cube 20 times.
(a) From Kala's results, odd number (1, 3 and 5) appearance is:
4 + 4 + 4 = 12
Thus, the experimental probability of rolling an odd number will be:
12/20 = 3/5
(b) If the cube is fair, we have the numbers have equal chance of appearance.
Theoretically, an odd numbers (1, 3 and 5) will have the probability of 3 out of 6 as illustrated with the numbers below:
1, 2, 3, 4, 5, 6
The theoretical probability of rolling an odd number will be:
3/6 = 1/2
(c)The true statement is:
With a small number of rolls, it is not surprising when the experimental probability is much greater than the theoretical probability.
Because when conducting a small number of rolls with a fair cube, the experimental probability may not necessarily align closely with the theoretical probability.
This difference is expected due to the limited sample size. As the number of rolls increases, the experimental probability tends to converge towards the theoretical probability.

for the semester, including a one time fee for room and board.
T = 1473c + 5495
What number represents the slope?
Interpret what the slope means in this situation.
What number represents the y-intercept?
Interpret what the y-intercept means in the situation.
The slope is represented by the number 1473 in the equation T = 1473c + 5495. The slope denotes the rate of change, or the amount by which the overall cost (T) rises with each new class attended (c).
In this scenario, the total cost of the semester increases by $1473 for each extra class attended at Michigan State University. The slope reflects the linear relationship between the total cos and the number of classes taken.
The number 5495 represents the y-intercept in the equation. When the number of classes (c) is 0, the y-intercept is the value of T. The y-intercept of $5495 shows the total cost for a semester at Michigan State University when no classes are taken. It includes a one-time accommodation and board price.
The y-intercept can be understood as the university's fixed cost component, which is independent of the number of classes taken. It includes expenditures such as housing and food plans that are incurred regardless of how many classes a student enrolls in.

5. Find the domain and the range for each of the following graphs.
Answer:
Domain: x [tex]\geq[/tex] -5
Range: y [tex]\geq[/tex] -3
Step-by-step explanation:
The domain is all the possible inputs or x value. x will be greater than -5.
The range is all of the possible outputs or y value. y will be greater than -3
Answer:
Domain: [-5, ∞)
Range: [-3, ∞)
Step-by-step explanation:
The given graph shows a continuous curve with a closed circle at the left endpoint (-5, -3) and an arrow at the right endpoint.
A closed circle indicates the value is included in the interval.
An arrow shows that the function continues indefinitely in that direction.
DomainThe domain of a function is the set of all possible input values (x-values).
As the leftmost x-value of the curve is x = -5, and it continues indefinitely in the positive direction, the domain of the graphed function is:
Interval notation: [-5, ∞)Inequality notation: x ≥ -5Set builder notation: {x ∈ R | x ≥ -5 }RangeThe range of a function is the set of all possible output values (y-values).
From observation, it appears that the minimum y-value of the curve is y = -3. The curve continues indefinitely in the positive direction in quadrant I. Therefore, the range of the graphed function is:
Interval notation: [-3, ∞)Inequality notation: y ≥ -3Set builder notation: {y ∈ R | y ≥ -3 }A community theater uses the function
p(d) = -4d? + 200d - 100 to model the profit (in
dollars) expected in a weekend when the tickets to a comedy show are priced at d dollars each. Cheaper tickets will bring in more people, while more expensive tickets will result in a higher revenue per person.
What is the vertex of the parabola when graphed, and what does it reveal about the situation?
The vertex (25, 2400) of the parabola reveals the optimal ticket price (25 dollars) that maximizes the profit (2400 dollars) for the theater during the comedy show.
To find the vertex of the parabola, we can use the formula:
x = -b / (2a)
In this case, the function is p(d) = -4d² + 200d - 100, which can be rewritten in the form of ax² + bx + c.
Comparing it with the standard form ax² + bx + c, we can see that a = -4, b = 200, and c = -100.
Now, let's substitute these values into the formula to find the vertex:
d = -200 / (2 * -4)
d = -200 / -8
d = 25
The x-coordinate of the vertex is 25. To find the corresponding y-coordinate, we substitute this value back into the original function:
p(25) = -4(25)² + 200(25) - 100
p(25) = -4(625) + 5000 - 100
p(25) = -2500 + 5000 - 100
p(25) = 2400
The y-coordinate of the vertex is 2400.
Therefore, the vertex of the parabola is (25, 2400).
The vertex reveals important information about the situation. In this case, it represents the optimal point for maximizing profit. The x-coordinate (25) represents the price at which the theater should set the tickets to maximize their profit. The y-coordinate (2400) represents the maximum profit achievable at that price.
Additionally, since the coefficient of the quadratic term (a) is negative (-4), it indicates that the parabola opens downwards, forming a concave shape. This means that as the ticket price increases or decreases from the optimal price, the profit will decrease. Therefore, setting the tickets at a price other than the one corresponding to the vertex would result in a lower profit for the theater.
In summary, the vertex (25, 2400) of the parabola reveals the optimal ticket price (25 dollars) that maximizes the profit (2400 dollars) for the theater during the comedy show.

If total amount is $3000, deposit c amount in one investment, how can you represent The rest in dollars?
The rest of the amount, represented by R, is $2000 in this case.
If the total amount is $3000 and a certain amount, c, is deposited in one investment, we can represent the remaining amount in dollars by subtracting the deposited amount from the total.
Let's denote the remaining amount as R.
R = Total amount - Deposit amount
R = $3000 - c
Here, R represents the rest of the amount in dollars after the deposit of c dollars. By subtracting the deposit amount from the total amount, we can determine the value of the remaining amount.
For example, if $1000 is deposited in one investment (c = $1000), we can find the remaining amount as follows:
R = $3000 - $1000
R = $2000
Therefore, the rest of the amount, represented by R, is $2000 in this case.

solve the PDE using separation of variables method Uxx = 1/2 Ut 0< X <3 with U(0,t) = U(3, t)=0, U(0, t) = 5sin(4πx)
The general solution of the partial differential equation is:
U(x, t) = Σ [Aₙ*sin((nπ/3)x)]*e^(-(nπ/3)²t)
How to solve Partial Differential Equations?The partial differential equation (PDE) is given as:
Uxx = (1/2)Ut with the boundary and initial conditions as 0< X <3 with U(0,t) = U(3, t)=0, U(0, t) = 5sin(4πx)
Assume that the solution can be written as a product of two functions:
U(x, t) = X(x)T(t)
Substituting this into the PDE, we have:
X''(x)T(t) = (1/2)X(x)T'(t)
Dividing both sides by X(x)T(t), we get:
(X''(x))/X(x) = (1/2)(T'(t))/T(t)
Since the left side only depends on x and the right side only depends on t, both sides must be equal to a constant, denoted as -λ²:
(X''(x))/X(x) = -λ²
(1/2)(T'(t))/T(t) = -λ²
Simplifying the second equation, we have:
T'(t)/T(t) = -2λ²
Solving the second equation, we find:
T(t) = Ce^(-2λ²t)
Applying the boundary condition U(0, t) = 0, we have:
U(0, t) = X(0)T(t) = 0
Since T(t) ≠ 0, we must have X(0) = 0.
Applying the boundary condition U(3, t) = 0, we have:
U(3, t) = X(3)T(t) = 0
Again, since T(t) ≠ 0, we must have X(3) = 0.
Therefore, we can conclude that X(x) must satisfy the following boundary value problem:
X''(x)/X(x) = -λ²
X(0) = 0
X(3) = 0
The general solution to this ordinary differential equation is given by:
X(x) = Asin(λx) + Bcos(λx)
Applying the initial condition U(x, 0) = 5*sin(4πx), we have:
U(x, 0) = X(x)T(0) = X(x)C
Comparing this with the given initial condition, we can conclude that T(0) = C = 5.
Therefore, the complete solution for U(x, t) is given by:
U(x, t) = Σ [Aₙsin(λₙx) + Bₙcos(λₙx)]*e^(-2(λₙ)²t)
where:
Σ represents the summation over all values of n
λₙ are the eigenvalues obtained from solving the boundary value problem for X(x).
To find the eigenvalues λₙ, we substitute the boundary conditions into the general solution for X(x):
X(0) = 0: Aₙsin(0) + Bₙcos(0) = 0
X(3) = 0: Aₙsin(3λₙ) + Bₙcos(3λₙ) = 0
From the first equation, we have Bₙ = 0.
From the second equation, we have Aₙ*sin(3λₙ) = 0. Since Aₙ ≠ 0, we must have sin(3λₙ) = 0.
This implies that 3λₙ = nπ, where n is an integer.
Therefore, λₙ = (nπ)/3.
Substituting the eigenvalues into the general solution, we have:
U(x, t) = Σ [Aₙ*sin((nπ/3)x)]*e^(-(nπ/3)²t)
where Aₙ are the coefficients that can be determined from the initial condition.

Find the 6terms of the series 247
The six terms of the series 247 are 2, 2, 2, 2, 2, and 2.
To find the six terms of a series, we need to first understand what a series is. A series is defined as the sum of the terms of a sequence. A sequence is a set of numbers in a specific order.
Therefore, a series is a sum of terms from a sequence. There are different types of series, and they have different formulas for calculating their terms.In this case, we are required to find the six terms of the series 247. Since this is a finite series, we can use a formula to calculate the nth term of a finite series.
The formula is given as follows:Tn = a + (n - 1) dWhere Tn is the nth term of the series, a is the first term of the series, n is the number of terms in the series, and d is the common difference between the terms of the series.To find the six terms of the series 247, we need to know the value of a and d. In this case, we can see that the first term of the series is 2. Therefore, a = 2.
Since this is a constant series, we can see that the common difference between the terms is 0. Therefore, d = 0.Substituting these values in the formula, we get:T1 = a + (1 - 1) dT1 = 2 + 0T1 = 2T2 = a + (2 - 1) dT2 = 2 + 0T2 = 2T3 = a + (3 - 1) dT3 = 2 + 0T3 = 2T4 = a + (4 - 1) dT4 = 2 + 0T4 = 2T5 = a + (5 - 1) dT5 = 2 + 0T5 = 2T6 = a + (6 - 1) dT6 = 2 + 0T6 = 2.

1. (a) The slope of the line parallel to the line; 5·x - 3·y = 10, can be obtained by writing the equation of the line in slope-intercept form as follows;
5·x - 3·y = 10, therefore; y = 5·x/3 - 10/3
The slope of the parallel line is therefore; 5/3
The point-slope form of the equation of the line is therefore;
y - 6 = (5/3)·(x - (-2)) = (5/3)·(x + 2)
y - 6 = (5/3)·(x + 2)
3·y - 18 = 5·x + 10
3·y - 5·x = 10 + 18 = 18
(b) The equation of the line, 2·x + 4·y - 12 = 0, indicates;
The slope of the line is; -2/4 = -1/2
The slope of the perpendicular line = -1/(-1/2) = 2
The equation of the perpendicular line passing through the point (2, -7) in point-slope form is therefore;
y - (-7) = 2·(x - 2)
y + 7 = 2·(x - 2)
(c) The line passing through point (-2, -4), and parallel to y = -3 is the line y = -4
(d) The line passing through point (4, -1), and perpendicular to x = 0 is the line y = -1
2. (a) f(-1) = 2 × (-1)² + (-1) - 1 = 0
f(3) = 2 × (3)² + (3) - 1 = 20
The average is; (f(3) - f(-1))/(3 - (-1)) = 20/4 = 5
(b) f(1) = 150, f(3) = 50
Average = (f(3) - f(1))/(3 - 1)
Average = (150 - 50)/(3 - 1) = 50
(c) f(4) = 4² - 4
f(4 + h) = (4 + h)² - (4 + h) = (h + 3)·(h + 4)
Average = (f(4 + h) - f(4))/(4 + h - 4) = ((h + 3)·(h + 4) - (4² - 4))/(h)
((h + 3)·(h + 4) - (4² - 4))/(h) = (h² + 7·h + 12 - 12)/h = h + 7

100 Points! Geometry question. Determine whether each pair of triangles is similar. If so, write a similarity statement. If not, what would be sufficient to prove the triangles similar? Explain your reasoning. Photo attached. Thank you!
Answer:
Yes; TSU ~ PJM
Step-by-step explanation:
Because the angle in between the sides are the same, we can see if each corresponding side is proportional to each other. If they are, then they are similar. (This is SAS similarity theorem)
First we can divide 10 by 15 and see if 14 divided by 21 is the same:
10/15 = 0.6666....
14/21 = 0.6666....
Yes, the two triangles are similar
Answer:
Δ STU [tex]\bold{\sim}[/tex] ΔPJM similar
Step-by-step explanation:
Similar triangles are two or more triangles that have the same shape, but their sides are in proportion. In other words, if you divide the length of any side of one triangle by the corresponding side of another triangle, you will get the same number.
For Question:
In Δ STU and ΔPJM
TS:US =10:14=5:7
PJ: JM=15:21= 5:7
Since the length of any side of one triangle is by the corresponding side of another triangle, you will get the same number.
Therefore,
Δ STU [tex]\bold{\sim}[/tex] ΔPJM is similar.

7. Here are two dot plots that represent the ages of the five children in each of two
Families
Dot plots are graphical displays of data that use dots to represent the frequency or count of a specific value in a data set. The ages of five children in each of two families are represented in the dot plots above.
Both dot plots have a similar range of ages, but family A has a higher median age and a smaller spread of ages than family B.
For family A, the median age is 10 years old because the middle dot in the plot is located at 10. Family A has a small range of ages because all the dots are concentrated in the 8-12 age range.
In contrast, family B has a wider range of ages, from 6 to 15 years old, and a larger spread because the dots are scattered across the plot.
The median age for family B is approximately 11 years old.
In conclusion, dot plots are useful for comparing data sets and analyzing their characteristics such as median age and spread.

What is the range of g(x)=-1/2(x-6)+1
Therefore, the range of the function g(x) = -1/2(x - 6) + 1 is all real numbers less than or equal to 1, written as (-∞, 1].
To determine the range of the function g(x) = -1/2(x - 6) + 1, we need to find the set of all possible output values or the range of the function.
The given function is in the form of a linear equation, specifically in slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept. In this case, the slope is -1/2 and the y-intercept is 1.
Since the slope is negative, it means the function is decreasing. The range of the function would be the set of all possible y-values that the function can produce. Since the function is decreasing, the maximum value it can reach is its initial y-intercept, which is 1.

Question 2(Multiple Choice Worth 2 points)
(Effects of Changes in Data MC)
The average high temperatures in degrees for a city are listed.
58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
If a value of 98° is added to the data, how does the mean change?
The mean increases by 8.2°.
The mean decreases by 8.2°.
The mean increases by 1.4°.
The mean decreases by 1.4°.
To determine how the mean changes when a value of 98° is added to the data, we need to calculate the mean before and after the addition.
Before adding 98°, the given data set has 12 values. We can calculate the mean by summing all the values and dividing by the total number of values:
Mean = (58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57) / 12
Mean ≈ 83.67°
After adding 98° to the data set, the total number of values becomes 13. To calculate the new mean, we sum all the values, including the added 98°, and divide by the total number of values:
New Mean = (58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 98) / 13
New Mean ≈ 86.15°
Therefore, the mean increases by approximately 2.48° when a value of 98° is added to the data. None of the provided answer choices accurately reflects this change, as they all mention different values (8.2° and 1.4°) that do not correspond to the actual change in the mean.

Answer:
We cannot determine if the triangles are similar.
Step-by-step explanation:
The diagram shows two triangles, ΔABC and ΔDEF.
The tick marks on the sides of the triangles show that two corresponding sides are congruent:
AB ≅ EDBC ≅ EFIn similar triangles:
Corresponding angles are the same size.Corresponding sides are always in the same ratio.As the diagram does not include any information about the interior angles or the length of the third side, we cannot determine if the triangles are similar.
To prove the triangles are similar by SAS similarity, we would need the measure of the included angles (angles B and E).
To prove the triangles are similar by SSS similarity, we would need the measure of the third side.
To prove the triangles are similar by AA similarity, we would need the measures of two corresponding angles.
