La probabilidad de que no haya demoras en un viaje de ida y vuelta es 0.64 (64%).
How to calculate the probabilities?La probabilidad de que no haya demoras en un viaje de ida y vuelta se puede calcular utilizando la probabilidad complementaria. Si la probabilidad de que un vuelo se retrase es 0.2 (20%), entonces la probabilidad de que no haya retrasos en un vuelo individual es 1 - 0.2 = 0.8 (80%).
Para un viaje de ida y vuelta, la probabilidad de que no haya retrasos en ambos vuelos se calcula multiplicando las probabilidades de no retraso de cada vuelo.
Entonces, la probabilidad de que no haya demoras en un viaje de ida y vuelta sería 0.8 * 0.8 = 0.64 (64%), o 64 de cada 100 viajes de ida y vuelta no experimentarían retrasos.

The graph shows the salaries of 23 employees at a small company. Each bar spans a width of $50,000 and the height shows the number of people whose salaries fall into that interval.
The owner is looking to hire one more person and when interviewing candidates says that on average an employee makes at least $175,000.
How does the owner justify this claim?
Answer:
Based on the given graph, we can see that the bars representing salaries above $175,000 span a total of 7 employee salaries. Since each bar spans a width of $50,000, we can estimate that the total number of employees making at least $175,000 is approximately 7 multiplied by 50,000 divided by 10,000, which equals 35%. Therefore, the owner can justify the claim that on average an employee makes at least $175,000 by stating that approximately 35% of the current employees already make at least that amount. However, it's important to note that this calculation is based on estimates and assumptions and should not be used as a definitive answer.
A rectangular prism with a square base has a height of 17. 2 cm and a volume of 24. 768 cm3. What is the side length of its base?
The side length of the base of the rectangular prism is approximately 1.2 cm.
What is rectangular prism?The top, bottom, and lateral faces of a rectangular prism are all rectangles, and all the pairings of the opposing faces are congruent. A rectangular prism is a three-dimensional structure with six faces.
Let's denote the side length of the base of the rectangular prism as "x" cm.
We know that the volume of a rectangular prism is given by the formula:
Volume = Base Area x Height
In this case, the base is a square, so its area is given by:
Base Area = x²
We are given that the volume is 24.768 cm³ and the height is 17.2 cm.
Therefore, we can write the equation:
24.768 = x² * 17.2
To find the value of x, we can rearrange the equation:
x² = 24.768 / 17.2
x² = 1.4376
Taking the square root of both sides, we get:
x = √1.4376
x ≈ 1.2
Therefore, the side length of the base of the rectangular prism is approximately 1.2 cm.

Question below, please help! this is part of my grade.. (30 points)
Answer:
y = 1 + 2√7 or y = 1 - 2√7
Step-by-step explanation:
To complete the square, you need to add and subtract the square of half of the coefficient of the y term.
First, you can factor out a 1 from the y^2 - 2y term:
y^2 - 2y - 27 = 0
y^2 - 2y = 27
Next, take half of the coefficient of the y term (-2/2 = -1) and square it (1):
y^2 - 2y + 1 - 1 = 27
The "+1 -1" doesn't change the value of the equation, it's just a way to add 0 to the equation so we can complete the square.
Now you can rewrite the left side as a perfect square:
(y - 1)^2 - 28 = 0
Add 28 to both sides:
(y - 1)^2 = 28
Take the square root of both sides (remembering to include both positive and negative square roots):
y - 1 = ±√28
y = 1 ± 2√7
So the solutions are:
y = 1 + 2√7
y = 1 - 2√7
Answer: y=± 2√7+1
6.29
Step-by-step explanation: Use the formula
(b/2)^2 in order to create a new term. Solve for y by using this term to complete the square.
Find f(a) if y = f(a) satisfies
dy/dx = 24yx³
and the y-intercept of the curve y = f(2) is 5. f(x) = ...
The solution to the differential equation is f(a) = 1/√(12a⁴/125 - 769/5000).
How to find the derivative of given equation?To find f(a), we need to solve the differential equation:
dy/dx = 24yx³
Separating variables, we get:
dy/y³ = 24x³ dx
Integrating both sides, we get:
-1/(2y²) = 6x⁴ + C
where C is the constant of integration.
To find the value of C, we use the fact that the y-intercept of the curve y = f(2) is 5. This means that when x = 2, y = 5. Substituting these values into the equation above, we get:
-1/(2(5)²) = 6(2)⁴ + C
Simplifying and solving for C, we get:
C = -1/(2(5)²) - 6(2)⁴
C = -769/125
So the solution to the differential equation is:
-1/(2y²) = 6x⁴ - 769/125
Solving for y, we get:
y = 1/√(12x⁴/125 - 769/5000)
Therefore, f(a) = 1/√(12a⁴/125 - 769/5000).

Identify the line of symmetry for the function below:
g(x) = |x +9|- 11
Answer:
x = -9
Step-by-step explanation:
As this is an absolute value function, the line of symmetry is the x-value of the maximum/minimum point. An absolute value function can be denoted as y = |x - h| + k, where (h, k) is the maximum/minimum point. We only need the x-value of the maximum/minimum point, so we only have to look at "h". Now, we can use y = |x - h| + k and turn it into g(x):
y = |x - h| + k
g(x) = |x - -9| + -11 --> this means h = -9, and the line of symmetry is at x = -9
g(x) = |x + 9| - 11
Answer:
I think x equals --9
Garden plots in the Portland Community Garden are rectangles limited to 45 square meters. Christopher and his friends want a plot that has a width of 7.5 meters. What length will give a plot that has the maximum area allowed?
The length that will give a plot with the maximum area allowed is 6 meters.
To find the length that will give a plot with the maximum area, we need to use the formula for the area of a rectangle, which is A = lw, where A is the area, l is the length, and w is the width. In this case, we are given that the area is 45 square meters, and the width is 7.5 meters.
Substituting these values into the formula, we get:
45 = l(7.5)
To solve for l, we divide both sides by 7.5:
l = 45/7.5
Simplifying, we get:
l = 6

7. How can you find distances between points in a coordinate plane?
1. The coordinates are: START: (0,0) END: (6,-4), 2. The perimeter of rectangle YARD is 20 units,3. The lengths of YX and YZ are 4 units and 6 units, respectively, 4. The area of Mary's room is 24 square units,
1-To get from one corner of his yard to another, Jason travels 4 units down and then 6 units right. Starting from the origin, his starting point is (0,0). From there, he moves 4 units down to the point (0,-4), and then 6 units right to reach his endpoint, which is at (6,-4).
2-The rectangle has two sides of length 4 and two sides of length 6. The perimeter is the sum of the lengths of all sides, so it is equal to 2(4) + 2(6) = 8 + 12 = 20 units.
3-The coordinates of points Y, X, and Z are not given, so we cannot calculate the lengths directly. However, we know that the sides of a rectangle are perpendicular, so we can use the Pythagorean theorem to find the lengths. Let Y be the origin (0,0), and let X be the point (0, -4). Then YX has length 4 units. Similarly, let Z be the point (6, 0), so YZ has length 6 units.
4.To find the area of a rectangle, we can multiply the lengths of its sides. From problem 3, we know that the lengths of the sides are 4 and 6 units, so the area is 4 x 6 = 24 square units.
5. The sides AB and AC form a right angle.
To determine which sides of the triangle form a right angle, we need to find the slope of each side. The slope of AB is (3-8)/(6-3) = -5/3, and the slope of AC is (3-3)/(6-3) = 0. Since the product of the slopes of two perpendicular lines is -1, we can see that AB is perpendicular to AC. Therefore, sides AB and AC form a right angle.
6. Tyler walks 9 blocks in all.
To find the distance Tyler walks, we need to calculate the length of sides AB and AC. Using the distance formula, we can find that the length of AB is sqrt[(6-3)² + (3-8)²] =√[(34) units, and the length of AC is 3 units. Therefore, Tyler walks 3 + √[34 units along the two sides that form the right angle. This is approximately 9.4 blocks, so he walks 9 blocks in all.
7. The distance between two points in a coordinate plane can be found using the distance formula:
d = √[(x₂-x₁)² + (y₂-y₁)²]
where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points, and d is the distance between them. The formula is derived from the Pythagorean theorem, which relates the sides of a right triangle.

What is 30 players for 10 sports expressed as a rate
The rate can be expressed as "3 players per sport"
What is rate?A rate is a ratio that compares two quantities with different units. In this case, we have 30 players and 10 sports. To express this as a rate, we want to compare the number of players to the number of sports. We can write this as:
30 players / 10 sports
To simplify this ratio, we can divide both the numerator (30 players) and denominator (10 sports) by the same factor to get an equivalent ratio. In this case, we can divide both by 10:
(30 players / 10) / (10 sports / 10)
This simplifies to:
3 players / 1 sport
So the rate can be expressed as "3 players per sport" or "3:1" (read as "three to one"). This means that for every one sport, there are three players.
Alternatively, we can express the rate as a fraction or decimal by dividing the number of players by the number of sports:
30 players / 10 sports = 3 players/sport = 3/1 = 3 or 3.0 (as a decimal)

If there was \$ 400$400 left after those two expenses, what was the original amount paid?
Amount paid = $
Answer is original amount paid to the transportation company was $800.
Let's work backwards from the final amount of $400 to find the original amount paid to the transportation company.
First, we know that percentage given is 80% of what was left after wages went towards supplies. So, if $400 was left after wages were paid, then:
0.8(400) = $320 went towards supplies.
Next, we know that 60% of the original amount went towards wages. So, if $320 went towards supplies, then the remaining amount that went towards wages was:
0.4(original amount) = $320

If a scale dilates a two dimensional object by factors of 2/3 it means that?
If a scale dilates a two-dimensional object by a factor of 2/3, it means that the image of the object will be reduced by a factor of 2/3. In other words, the length and width of the image will be 2/3 of the length and width of the original object.
For instance, consider a rectangle with length L and width W. If we dilate this rectangle by a factor of 2/3, the new length and width of the rectangle will be (2/3)L and (2/3)W, respectively. The area of the new rectangle will be (2/3)L x (2/3)W = (4/9)LW, which is 4/9 of the original area. This means that the image is smaller than the original rectangle, and this type of dilation is called a reduction.
Dilations can be used in different applications of mathematics, such as geometry, trigonometry, and algebra. They are useful for changing the scale or size of an object in a proportional way, without altering its basic shape or characteristics.

Philip owns 100 shares of a stock that is trading at $97. 55 and pays an annual dividend of $2. 74. How much should he receive in quarterly dividends? What's the annual yield on this stock?
Philip should receive $68.50 in quarterly dividends and the annual yield on this stock is about 2.81%.
To calculate the quarterly dividend that Philip need to acquire, we need to first calculate the quarterly dividend per share:
Quarterly dividend in step with share = Annual dividend per percentage / 4
In this situation, the once a year dividend in line with proportion is $2.74, so the quarterly dividend per proportion is:
Quarterly dividend per proportion = $2.74 / 4 = $0.685
For the reason that Philip owns 100 shares, his quarterly dividend should be:
Quarterly dividend = Quarterly dividend per share * number of stocks
Quarterly dividend = $0.685 * 100 = $68.50
Therefore, Philip should receive $68.50 in quarterly dividends.
To calculate the once a year yield on this inventory, we want to divide the yearly dividend in line with proportion by the present day stock price, after which multiply by way of 100 to specific the result as a percentage:
Annual yield = (Annual dividend per share / inventory price) * 100
In this case, the annual dividend per percentage is $2.74, and the inventory charge is $97.55. Plugging those values into the components, we get:
Annual yield = ($2.74 / $97.55) * 100
Annual yield ≈ 2.81%
Therefore, the annual yield on this stock is about 2.81%.

P is the monthly payment r is the yearly interest rateA is the principal (i.e., the original amount borrowed) n is the number of payments (i.e., the number of years multiplied by 12)r is the annual interest rate (stated as a decimal and constantly compounded)Plugging in the given values, we get:
P = (0.046 * 35000) / (1 - (1 + 0.046/12)^(-6*12))
P ≈ $640.62
Therefore, the monthly payment on the car is approximately $640.62.

1.whats the functions minimum value?
2.where does the minimum value occur?
The minimum value of the function is -13 and the minimum value of the function occurs at the point (4, -13).
The function F(x) is a quadratic function with a negative coefficient of the squared term.
Therefore, the function has a maximum value.
To find the maximum value, we need to find the vertex of the parabola.
The x-coordinate of the vertex is given by x = -b/2a, where a and b are the coefficients of the x² and x terms respectively.
In this case, a = -1 and b = -8, so x = -(-8)/(2(-1)) = 4.
To find the minimum value, we substitute this x-value into the function to get F(4) = -(4²) - 8(4) + 19 = -13.
Therefore, the minimum value of the function is -13.
We found in part (1) that the x-coordinate of the vertex is x = 4.
To find the y-coordinate, we substitute this x-value into the function to get F(4) = -13.
Therefore, the minimum value of the function occurs at the point (4, -13).

The housing market has been very intense since 2020 when the pandemic began. People in Southern California as well as across the USA wanted to buy homes away from cities with a prefence towards the suburbs and rural areas. Southern California homes experienced a 12. 6 % year over year increase in price gains since 2020 and this is still going on. Inventory is too low, that is the supply of homes is low. Home builders aren't able to build fast enough to keep up with demand, or won't. A: If a modest 2 bedroom 2 bathroom house in Santa Barbara county used to cost $567,000 in 2020, give the exponential formula that models the price of this house over time, assuming the percent appreciation sustains currently and into the future. Let P(t) be the "asking price" of the house. Let "r" be the rate of the appreciation value. Let t be time in years. Use decimals only. B: What would be the price of such a house in 2022? ( Round your answer to two places after the decimal, also known as the hundredths place).
A: P(t) [tex]= $567,000 * (1 + 0.126)^t[/tex]
B: [tex]567,000 * (1 + 0.126)^2 = $671,448.14[/tex]
How can we calculate the price of a 2 bedroom 2 bathroom house in Santa Barbara county in 2022, assuming the current rate of appreciation continues?A: To model the price of the house over time, we can use the exponential formula: P(t) = P₀ * (1 + r)^t, where P₀ is the initial price, r is the rate of appreciation, and t is the time in years.
In this case, the initial price (P₀) of the house is $567,000 and the rate of appreciation (r) is 12.6% expressed as a decimal, which is 0.126. Therefore, the exponential formula to model the price of the house over time would be: P(t) = 567,000 * (1 + 0.126)^t.
B: To find the price of the house in 2022, we substitute t = 2022 - 2020 = 2 into the exponential formula.
P(2) = 567,000 * (1 + 0.126)^2
P(2) = 567,000 * (1.126)^2
P(2) ≈ 567,000 * 1.268
P(2) ≈ $719,976.00
Therefore, the price of such a house in 2022 would be approximately $719,976.00
