A few years ago, Sarah acquired a parcel of land valued at $14,300 . Today, that same parcel of land has a value of $15,444 . Find the percent increase in the property's value. Round your answer to the nearest hundredth, if necessary.
The percent increase in the vaIue οf the parceI οf Iand is 8%.
Tο find the percent increase in the vaIue οf the parceI οf Iand, we need tο determine the difference between the current vaIue and the οriginaI vaIue, and then express that difference as a percentage οf the οriginaI vaIue.
What is the fοrmuIa fοr percent increase?percent increase = (new vaIue - οId vaIue) / οId vaIue x 100%
PIugging in the vaIues given in the prοbIem, we get:
percent increase = ($15,444 - $14,300) / $14,300 x 100%
percent increase = $1,144 / $14,300 x 100%
percent increase = 0.08 x 100%
percent increase = 8%
Therefοre, the percent increase in the vaIue οf the parceI οf Iand is 8%.

D. 20
240 more residents have an occupation in industry than have an occupation in government. The solution has been obtained by using arithmetic operations.
It is believed that the four fundamental operations, often referred to as "arithmetic operations", can describe all real numbers. The four mathematical operations that produce the quotient, product, sum, and difference are divide, multiply, add, and subtract.
We are given a graph determining the types of occupations of the 1,200 residents of a town.
Percentage of residents having occupation in government is:
100% - 25% - 15% - 25% - 30% = 5%
Number of residents having occupation in industry is as follows:
25% of 1200 = 300
Similarly, number of residents having occupation in government is:
5% of 1200 = 60
Number of more residents that have occupation in industry than have an occupation in government is:
300 - 60 = 240
Hence, 240 more residents have an occupation in industry than have an occupation in government.

What is the vertical asymptote and horizontal asymptote pic attached below
The required horizontal and vertical asymptote is x = 2, -2, and y = 1/4.
How to find Asymptotes?To find the vertical asymptotes of the given rational function, we need to look for values of x that make the denominator zero, since division by zero is undefined.
The denominator of the function is 4(x-2)(x+2), so the vertical asymptotes occur at x = 2 and x = -2. Therefore, the vertical asymptotes are:
x = 2, -2
To find the horizontal asymptote, we can use the fact that as x goes to positive or negative infinity, the function approaches the ratio of the leading coefficients of the numerator and denominator.
In this case, the leading term in the numerator is x² and the leading term in the denominator is 4x². Therefore, as x approaches positive or negative infinity, the function approaches:
y = (x² / 4x²) = 1/4
So, the horizontal asymptote is:
y = 1/4

he three data sets have the same mean and range, but is the variation the same? Prove your answer by computing the standard deviation. Assume the data were obtained from samples. (a) 4, 5, 11, 13, 13, 14 (b) 5, 7, 10, 10, 13, 15 (c) 3, 10, 11, 11, 12, 13
The standard deviations of the data are different.
Standard deviation:
The formula used to calculate the standard deviation of data is given by
Standard deviation = √[ ∑(x[tex]_{i}[/tex] - x)² /n ]x - mean of the data and n = number of observations
Here we have
(a) 4, 5, 11, 13, 13, 14
Mean of the data = [4 + 5 + 11 + 13 + 13 + 14 ]/6 = 60/6 = 10
On calculating deviations
=> ∑(x[tex]_{i}[/tex] - x)² = 96
=> √[ ∑(x[tex]_{i}[/tex] - x)²/n ] = √[ 96/ 6 ] = 4
(b) 5, 7, 10, 10, 13, 15
Since the mean of the data is equal for all
On calculating deviations
=> ∑(x[tex]_{i}[/tex] - x)² = 68

The number of trout in a stocked lake is given by the
equation T = 1800 (1.15)n where n is the number of months since the start of the trout season.
a. How many trout will there be in 2.5 months?
b. How many trout were there 2 months before the season opened?
a. To find the number of trout in 2.5 months, we can substitute n = 2.5 into the given equation:
T = 1800 (1.15)^n
T = 1800 (1.15)^2.5
T ≈ 2708.67
Therefore, there will be approximately 2,709 trout in the lake after 2.5 months.
b. To find the number of trout 2 months before the season opened, we need to use a negative value of n that represents the time before the start of the trout season. If we assume that the start of the season is month 0, then 2 months before the start of the season would be month -2. Thus, we can substitute n = -2 into the given equation:
T = 1800 (1.15)^n
T = 1800 (1.15)^(-2)
T ≈ 980.92
Therefore, there were approximately 981 trout in the lake 2 months before the start of the trout season.

Option C i.e. number line with closed circle on negative 2 with arrow shaded right represents the solution to the inequality.
What is inequality?
An inequality is a comparison relationship between two or more mathematical expressions.
We are given an inequality as 0.5 is greater than or equal to the product of a number and −0.25.
Let the number be x.
So, from the above information, we get the inequality as
0.5 ≥ -0.25x
Now, on solving the above inequality, we get the following
0.5 ≥ -0.25x
On multiplying by -1, we get
⇒-0.5 ≤ 0.25x
On dividing both sides by 0.25, we get
⇒-2 < x
Hence, Option C i.e. number line with closed circle on negative 2 with arrow shaded right represents the solution to the inequality.

What is a number series?A number series is a sequence of numbers. To answer the questions regarding number series, we must first establish the rules that lead to the production of a number series.
The reverse of 63 is 36.
The sum of the digits of 63 is 6 + 3 = 9.
So, the following number is 36 + 9 = 45, followed by the next odd number, 47. Hence the following number is 47.
The reverse of 00 is 00.
The sum of the digits of 00 is 0 + 0 = 0.
So, the following number is 0 + 0= 0, followed by the next odd number, 0. Hence the following number is 0.
The reverse of 22 is 22.
The sum of the digits of 22 is 2 + 2 = 4.
So, the following number is 22 + 4 = 26, followed by the next odd number, 27. Hence the following number is 27.

By answering the above question, we may state that As a result, the coordinates graph's line has the equation y = (4/5)x + 11/5.
what are coordinates?A coordinate system in geometry is a method that employs one or more integers or coordinates to identify the precise placement of points or other geometrical objects on a manifold, such as Euclidean space. Pairs of integers called coordinates are used to locate a point or object on a two-dimensional plane. The position of a point on a 2D plane is described by two integers known as the x and y coordinates. a group of numbers that represent precise positions. Usually, there are two numbers in the figure. The front-to-back distance is represented by the first number, while the top-to-bottom distance is represented by the second number. like in (12.5), when there are 12 units below and 5 above.
In order to determine the line's equation, we must first determine the slope (m) of the line using the following formula:
m = (y2 - y1) / (x2 - x1) (x2 - x1)
where the coordinates of the two sites the line travels through are (x1, y1) and (x2, y2), respectively.
In place of the values we hold:
m = (7 - 3) / (6 - 1) (6 - 1)
m = 4 / 5
Now that we have the slope, we can solve the equation of a line using the point-slope form, which is:
y - y1 = m(x - x1) (x - x1)
where one of the locations the line travels through is (x1, y1).
y - 3 = (4/5)(x - 1) (x - 1)
y = (4/5)x - 4/5 + 3 y = (4/5)x + 11/5 is equal to y - 3 = (4/5)x - 4/5.
As a result, the graph's line has the equation y = (4/5)x + 11/5.
