Find x for this equation
Show clear algebraic fraction
Answer:
x = \(\frac{8}{3}\)
Step-by-step explanation:
\(\frac{2}{5x-2}\) = \(\frac{3}{6x+1}\) ( cross- multiply )
3(5x - 2) = (2(6x + 1) ← distribute parenthesis on both sides )
15x - 6 = 12x + 2 ( subtract 12x from both sides )
3x - 6 = 2 ( add 6 to both sides )
3x = 8 ( divide both sides by 3 )
x = \(\frac{8}{3}\)

Given the costs of 10 college math textbooks, we can calculate that:
a. The median is 70
b. The mean is 70.3
c. The variance is 2.01 and the standard deviation is 1.42
Median, mean, variance, and standard deviation
Median, mean, variance, and standard deviation are very basic but very important concepts of statistics.
Median is the middle value of the data that has been arranged sequentially from the smallest to the largest.
The median for the number of data (n) is odd:
\(M_{e} = x_{(\frac{n+1}{2} )}\)
The median for the number of data (n) is even:
\(M_{e} = \frac{1}{2} (x_{(\frac{n}{2})} + x_{(\frac{n}{2} +1)} )\)
Mean is the average of all data in a sample group, which is obtained by adding up all the data values, then dividing by the number of samples.
\(Mean = \frac{Sum of all data}{size of data (n)}\)
Variance is a value that describes the variation of data, by measuring how far each piece of data is spread from the average of a data set.
\(Variance = \frac{sum (x_{i} - mean)^{2}}{n}\)
Standard Deviation is a measure of the spread of observations in a data set relative to their mean. it measures how many observations in a data set differ from the mean and is the square root of the variance.
σ = \(\sqrt{variance}\)
To do the problem, we first create a table for the given data.
Then we calculate the median as follows:
\(M_{e} = \frac{1}{2} (x_{(\frac{n}{2})} + x_{(\frac{n}{2} +1)} )\\= \frac{1}{2} (x_{5} + x_{6} )\\\)
= 1/2 (70 + 70)
= 70
After that, we calculate the mean as follows:
\(Mean = \frac{Sum of all data}{size of data (n)}\)
= (70 + 72 + 71 + 70 + 69 + 73 + 69 + 68 + 70 + 71) / 10
= 703 / 10
= 70.3
Now we calculate the difference between the data and the mean and put it into the table, and find the sum.
Then we can calculate the variance as follows:
\(Variance = \frac{sum (x_{i} - mean)^{2}}{n}\)
= 20.1 / 10
= 2.01
Standard deviation can be calculated from the variance:
σ = \(\sqrt{variance}\)
= \(\sqrt{2.01}\)

Si Verónica, Ana y Luis están pintando una barda y se les paga un total de 300 unidades monetarias (por ejemplo, dólares, pesos, etc.), para determinar cuánto dinero debería recibir cada uno, necesitamos más información sobre cómo se distribuye el trabajo entre ellos.
Si los tres contribuyen de manera equitativa y realizan la misma cantidad de trabajo, podrían dividir el pago de manera igualitaria. En ese caso, cada uno recibiría 100 unidades monetarias (300 dividido entre 3).
Sin embargo, si uno de ellos realiza más trabajo o tiene una mayor responsabilidad en la tarea, podría ser justo que reciba una porción mayor del pago. En ese caso, la distribución de los 300 unidades monetarias dependerá de un acuerdo previo entre ellos sobre cómo se divide el pago en función de la cantidad o calidad del trabajo realizado.

A 2-column table with 4 rows. Column 1 is labeled x with entries negative 6, negative 4, 4, 6. Column 2 is lab
eled y with entries negative 26, negative 14, 34, 46.
The linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.
To determine the linear function with the same y-intercept as the graph, we need to find the equation of the line passing through the points (3, 4) and (5, 0).
First, let's find the slope of the line using the formula:
slope (m) = (change in y) / (change in x)
m = (0 - 4) / (5 - 3)
m = -4 / 2
m = -2
Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:
y - y1 = m(x - x1)
Using the point (3, 4) as our reference point, we have:
y - 4 = -2(x - 3)
Expanding the equation:
y - 4 = -2x + 6
Simplifying:
y = -2x + 10
Now, let's check the given options to find the linear function with the same y-intercept:
Option 1: The table with x-values (-3, -1, 1, 3) and y-values (-4, 2, 8, 14)
The y-intercept is not the same as the given line. So, this option is not correct.
Option 2: The table with x-values (-4, -2, 2, 4) and y-values (-26, -18, -2, 6)
The y-intercept is not the same as the given line. So, this option is not correct.
Option 3: The table with x-values (-5, -3, 3, 5) and y-values (-15, -11, 1, 5)
The y-intercept is the same as the given line (10). So, this option is correct.
Option 4: The table with x-values (-6, -4, 4, 6) and y-values (-26, -14, 34, 46)
The y-intercept is not the same as the given line. So, this option is not correct.
Therefore, the linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

Each side of a square is increasing at a rate of 4 cm/s. At what rate (in cm2/s) is the area of the square increasing when the area of the square is 25 cm2
Answer:
The area of the square is increasing at a rate of 40 square centimeters per second.
Step-by-step explanation:
The area of the square (\(A\)), in square centimeters, is represented by the following function:
\(A = l^{2}\) (1)
Where \(l\) is the side length, in centimeters.
Then, we derive (1) in time to calculate the rate of change of the area of the square (\(\frac{dA}{dt}\)), in square centimeters per second:
\(\frac{dA}{dt} = 2\cdot l \cdot \frac{dl}{dt}\)
\(\frac{dA}{dt} = 2\cdot \sqrt{A}\cdot \frac{dl}{dt}\) (2)
Where \(\frac{dl}{dt}\) is the rate of change of the side length, in centimeters per second.
If we know that \(A = 25\,cm^{2}\) and \(\frac{dl}{dt} = 4\,\frac{cm}{s}\), then the rate of change of the area of the square is:
\(\frac{dA}{dt} = 2\cdot \sqrt{25\,cm^{2}}\cdot \left(4\,\frac{cm}{s} \right)\)
\(\frac{dA}{dt} = 40\,\frac{cm^{2}}{s}\)
The area of the square is increasing at a rate of 40 square centimeters per second.

You are given the great circle of a sphere is a length of 25 miles. What is the volume of the sphere
The volume of the sphere is approximately 3431.82 cubic miles.
To find the volume of a sphere, we need the radius of the sphere. The length of a great circle is the circumference of the sphere, which is related to the radius by the formula C = 2πr, where C is the circumference and r is the radius.
In this case, we are given that the length of the great circle is 60 miles. We can use this information to find the radius of the sphere.
C = 2πr
60 = 2πr
Divide both sides of the equation by 2π:
r = 60 / (2π)
r = 30 / π
Now that we have the radius, we can use the formula for the volume of a sphere:
V = (4/3)πr³
V = (4/3)π(30/π)³
V = (4/3)π(27000/π³)
V = (4/3)π(27000/π³)
V = (4/3)π(27000/π³)
V = (4/3)(27000/π²)
V = (4/3)(27000/9.87) (approximating π to 3.14)
V ≈ 3431.82 cubic miles
Therefore, the volume of the sphere is approximately 3431.82 cubic miles.

Answer:
To multiply 1.3 by 2.1, we need to use the distributive property of multiplication, which states that:
a × (b + c) = a × b + a × c
Using this property, we can break down 2.1 as the sum of 2 and 0.1:
1.3 × 2.1 = 1.3 × (2 + 0.1)
= 1.3 × 2 + 1.3 × 0.1

8 = 2x
x = 4
Solve for y :

As an ordered pair, the solution is then the point (x, y) = (4, -7/2).
Consider the function below, which has a relative minimum located at (-3, -18) and a relative maximum located at 1/3, 14/27). f(x) = -x3 - 4x2 + 3x. Select all ordered pairs in the table which are located where the graph of f(x) is decreasing: Ordered pairs: (-1, -6), (2, -18), (0, 0),(1 , -2), (-3 , -18), (-4. , -12)
The ordered pairs (-1, -6), (2, -18), (0, 0), and (-4, -12) do not correspond to the intervals where the graph of f(x) is decreasing. The pairs (1, -2) and (-3, -18) are the correct ones.
To determine where the graph of f(x) is decreasing, we need to examine the intervals where the function's derivative is negative. The derivative of f(x) is given by f'(x) = -3x^2 - 8x + 3.
Now, let's evaluate f'(x) for each of the given x-values:
f'(-1) = -3(-1)^2 - 8(-1) + 3 = -3 + 8 + 3 = 8
f'(2) = -3(2)^2 - 8(2) + 3 = -12 - 16 + 3 = -25
f'(0) = -3(0)^2 - 8(0) + 3 = 3
f'(1) = -3(1)^2 - 8(1) + 3 = -3 - 8 + 3 = -8
f'(-3) = -3(-3)^2 - 8(-3) + 3 = -27 + 24 + 3 = 0
f'(-4) = -3(-4)^2 - 8(-4) + 3 = -48 + 32 + 3 = -13
From the values above, we can determine the intervals where f(x) is decreasing:
f(x) is decreasing for x in the interval (-∞, -3).
f(x) is decreasing for x in the interval (1, 2).
Now let's check the ordered pairs in the table:
(-1, -6): Not in a decreasing interval.
(2, -18): Not in a decreasing interval.
(0, 0): Not in a decreasing interval.
(1, -2): In a decreasing interval.
(-3, -18): In a decreasing interval.
