A property sells for $620,000 two years after it was purchased. If the annual appreciation rate was 4%, how much did the original buyer pay for the property (round to the nearest $1,000)?
The original purchase price of the property, after accounting for 4% annual appreciation over two years with a final selling price of $620,000, is approximately $573,000 when rounded to the nearest $1,000.
Explanation:The question involves finding the original price of a property given its final selling price after a period of annual appreciation. To calculate the original purchase price, we need to use the formula for compound appreciation in reverse, known as discounting. Since the appreciation is 4% per year for two years and the final selling price is $620,000, the original purchase price (P) can be found using the formula:
P = Final Price / (1 + rate of appreciation)^number of years
So, substituting the given values, we get:
P = $620,000 / (1 + 0.04)^2
Now, calculate the denominator:
(1 + 0.04)^2 = 1.0816
And then divide by the final price:
P = $620,000 / 1.0816
P = $573,029.94
When rounded to the nearest $1,000, the original purchase price is approximately $573,000.

Step-by-step explanation:
In a six-sided dice game, a prize is won if the arithmetic mean of number rolled is 3.25-3.75. In a second game, a prize is won if the arithmetic mean is more than 4.5. In which game would you rather roll the dice 20 times or 200 times
For rolling the dice 200 times, the same logic applies. Regardless of the number of rolls, the game with the higher probability of winning, which is the second game, is preferred.
To determine which game is more favorable for rolling the dice, we need to calculate the expected value for each game. The expected value represents the average outcome of rolling the dice.
For the first game, the possible outcomes are integers between 1 and 6. The arithmetic mean should be between 3.25 and 3.75 to win a prize. So, we need to find the probability of rolling numbers that satisfy this condition.
Let's denote [tex]\( p_1 \)[/tex] as the probability of winning the first game. To find [tex]\( p_1 \)[/tex], we calculate the probability of rolling numbers between 13 and 18 (inclusive) since the sum of these numbers falls within the range of 3.25 to 3.75.
[tex]\[ p_1 = \frac{6}{6^2} = \frac{1}{6} \][/tex]
For the second game, we need the arithmetic mean to be more than 4.5. This means the sum of the numbers should be more than [tex]\( 4.5 \times 6 = 27 \)[/tex]. Since the maximum sum of rolling six dice is 36, all outcomes satisfy this condition.
Let's denote [tex]\( p_2 \)[/tex] as the probability of winning the second game. Since all outcomes are favorable, [tex]\( p_2 = 1 \)[/tex].
Now, we calculate the expected values for each game:
[tex]\[ E_1 = p_1 \times \text{Prize amount for game 1} \][/tex]
[tex]\[ E_2 = p_2 \times \text{Prize amount for game 2} \][/tex]
Given that the prize amount is the same for both games, we can compare the expected values directly.
For rolling the dice 20 times:
[tex]\[ E_1 = \frac{1}{6} \times \text{Prize amount} \][/tex]
[tex]\[ E_2 = 1 \times \text{Prize amount} \][/tex]
Since [tex]\( \frac{1}{6} \)[/tex] is less than 1, it's better to choose the game with the higher probability, which is the second game.
For rolling the dice 200 times, the same logic applies. Regardless of the number of rolls, the game with the higher probability of winning, which is the second game, is preferred.
The complete question is:
In a six-sided dice game, a prize is won if the arithmetic mean of number rolled is 3.25-3.75. In a second game, a prize is won if the arithmetic mean is more than 4.5. In which game would you rather roll the dice 20 times or 200 times

The area of the ice surface of a skating rink is about 221 yd2. The rink is about the shape of a rectangle where the ice-surface width is 4 yd longer than its length. Find the dimensions of the surface
"The dimensions of the ice surface are approximately 25 yd in length and 29 yd in width.
To find the dimensions of the ice surface, we need to solve for the length and width of the rectangle, given that the area is 221 yd² and the width is 4 yd longer than the length. Let's denote the length of the rink as l and the width as w. We can then set up the following equations based on the given information:
1. The area of a rectangle is given by the product of its length and width, so we have:
[tex]\[ l \times w = 221 \][/tex]
2. The width is 4 yd longer than the length, so we have:
[tex]\[ w = l + 4 \][/tex]
Now we can substitute the second equation into the first equation to express the area solely in terms of the length I:
[tex]\[ l \times (l + 4) = 221 \][/tex]
Expanding the equation, we get:
[tex]\[ l^2 + 4l = 221 \][/tex]
Rearranging the terms to set the equation to zero, we have a quadratic equation:
[tex]\[ l^2 + 4l - 221 = 0 \][/tex]
To solve this quadratic equation, we can factor it or use the quadratic formula. Factoring, we look for two numbers that multiply to -221 and add up to 4. These numbers are 13 and -17. So we can rewrite the equation as:
[tex]\[ (l + 17)(l - 13) = 0 \][/tex]
Setting each factor equal to zero gives us two possible solutions for l:
[tex]\[ l + 17 = 0 \quad \text{or} \quad l - 13 = 0 \] \[ l = -17 \quad \text{or} \quad l = 13 \][/tex]
Since a negative length does not make sense in this context, we discard l = -17 and take l = 13 yd as the length of the rink.
Now we can find the width w by adding 4 yd to the length:
[tex]\[ w = l + 4 \] \[ w = 13 + 4 \] \[ w = 17 \][/tex]
However, we made a mistake in the factoring process. The correct factors of 221 that add up to 4 are 17 and 13, not -17 and 13. The correct length should be 13 yd, and the width should be:
[tex]\[ w = l + 4 \] \[ w = 13 + 4 \] \[ w = 29 \][/tex]
Therefore, the correct dimensions of the ice surface are 13 yd in length and 29 yd in width.

To calculate the property tax on Christine and Gene's home, multiply the tax rate of 0.0175 (converted from $17.50 per $1,000) by the assessed value of $230,000. The annual property tax on their home would be $4,025.
Explanation:The student is asking how to calculate the property tax on Christine and Gene's home. To calculate this, you need to use the assessed value of the property and the property tax rate. Here is the step-by-step calculation:
Property tax rate = $17.50 per $1,000 of assessed value.Assessed value of the home = $230,000.To find the property tax, convert the tax rate to a decimal by dividing by 1,000, resulting in 0.0175 ($17.50 / $1,000).Multiply the resulting decimal by the assessed value: Property tax = 0.0175 * $230,000.The calculation is:
Property tax = 0.0175 * $230,000 = $4,025
Therefore, the annual property tax on their home is $4,025.

tell whether the measure can be the side lengths of a triangle. if so classify the triangle as acute obtuse or right
Using the Triangle Inequality Theorem and the Pythagorean theorem, we can determine if a given set of measures can form a triangle, and if so, what type of triangle (acute, obtuse, or right) it is. We find that measures a) 4,7,9; b) 10,13,16; c) 8,8,11; d) 9,12,15 and f) 4.5,6,10.2 can all form triangles, but e) 5,14,20 cannot. The triangles formed are respectively acute, obtuse, acute, right, and obtuse.
Explanation:Triangular Side Lengths and IdentificationIn the discipline of Mathematics, specifically Geometry, we use the Triangle Inequality Theorem and the Pythagorean theorem to determine if given measures can constitute the sides of a triangle and also classify the triangle. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be larger than the length of the third side. The Pythagorean theorem (a² + b² = c²) is especially used to identity right triangles, but can also support in the identification of obtuse and acute triangles.
4,7,9 - These lengths can form a triangle. Since 4² + 7² > 9², the triangle is acute.10,13,16 - These lengths can form a triangle. However, since 10² + 13² < 16², the triangle is obtuse.8,8,11 - These lengths can form a triangle. Since 8² + 8² > 11², the triangle is acute.9,12,15 - These lengths can form a triangle. As 9² + 12² = 15², this is a right triangle.5,14,20 - These lengths cannot form a triangle as 5 + 14 < 20, which means it violates the Triangle Inequality Theorem.4.5,6,10.2 - These lengths can form a triangle. As 4.5² + 6² < 10.2², it is an obtuse triangle.Learn more about Triangle Classification here:https://brainly.com/question/4028542

Which best summarizes the Pythagorean theorem
The Pythagorean theorem, usually applied in right-angled triangles, states the square of the hypotenuse equals the sum of the squares of the other two sides. This can be summarized by the equation: a² + b² = c². It is a fundamental principle in geometry.
Explanation:The Pythagorean theorem is a mathematical principle that applies specifically to right-angled triangles. The theorem, credited to the ancient Greek philosopher Pythagoras, stipulates that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This relationship can be represented by the equation: a² + b² = c², where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.
For example, if one side of the triangle (a) is 3 units and the other side (b) is 4 units, the length of the hypotenuse (c) can be calculated using the Pythagorean theorem. The calculation would be set as follows: 3² + 4² = c². When solved, it results in c = √(3² + 4²) = √(9 + 16) = √25 = 5 units. Therefore, the length of the hypotenuse in this case is 5 units.
