farmer recently sold a large plot of land. The sale decreased his total acreage by 3%. Let w be the original acreage. Find two equivalent expressions that will give the new acreage. Use pencil and paper. Use the expressions to describe two ways to find the new acreage.
Will give brainilest
Answers
The correct answers are option C and option E.
what is acreage ?
Acreage is a term used to refer to the total area of land that a particular property or piece of land covers, measured in acres. An acre is a unit of area commonly used in the United States and other countries for measuring land, and is equivalent to 43,560 square feet or about 4047 square meters. Acreage is often used in real estate and agriculture to describe the size of a property or land for various purposes, such as determining its value, calculating taxes, or planning land use.
Given by the question:
The new acreage after the sale is equal to 97% of the original acreage, since the sale decreased the total acreage by 3%. Therefore, two equivalent expressions for the new acreage are:
E. w - 0.03w (since subtracting 3% of w from w gives 97% of w, which is the new acreage)
Option C. 0.97w is also equivalent to the new acreage. However, options A, B, D, and F are not equivalent expressions for the new acreage.

Given Eq:
√x + 3 = x - 3Solving this:
Squaring both sides,
➝ x + 3 = (x - 3)²
➝ x + 3 = x² - 6x + 9
Now shifting RHS to LHS,
➝ x + 3 - x² + 6x - 9 = 0
➝ -x² + 7x - 6 = 0
➝ x² - 7x + 6 = 0
Now finding the values of x by middle term factorisation,
➝ x² - 6x - x + 6 = 0
➝ x(x - 6) - 1(x - 6) = 0
➝ (x - 1)(x - 6) = 0
➝ x = 1 or 6.
But here, you can see, x = 1 is not a solution to the original equation because when we say about square roots, value can't be negative.
Hence,
As a result, the only valid solution to the original equation is x = 6.⛱️ \( \large{ \blue{ \bf{FadedElla}}}\)

What is the solution to inequality?To solve inequality in y, we need a number such that the assertion holds if we replace y with that number. Isolating the variable on one side of the inequality and leaving the other terms constant is the first step in resolving the inequality.
From the given information:
4x + 1 = 9 + 4y
To solve for y, we have to switch the sides:
9 + 4y = 4x + 1
Subtract 9 from both sides
9 - 9 + 4y = 4x + 1 - 9
4y = 4x - 8
Divide both sides by 4
\(\dfrac{4y}{4}= \dfrac{4x}{4}-\dfrac{8}{4}\)
y = x - 2

How do you describe the graph of linear equation in terms of its intercept and?
Answers
The slope-intercept form of the equation is y = - mx + b.
The equation of a line can be expressed in a variety of ways. Although they may differ in appearance, all of them describe the same line because multiple equations can describe the same line. However, all linear equations describing the same line are equivalent.
The formula y = mx + b can be used to represent any straight line. Any straight line equation, known as a linear equation, can be expressed as y = mx + b, where m denotes the line's slope and b its y-intercept. The value of y at the line's intersection with the y-axis is its y-intercept.
Given a graph of the equation, choose two points on the line and use them to calculate the slope in order to put the equation in slope-intercept form. This is the answer to the equation's question. Next, determine the y-coordinates, intercept's which should be of the type (0,b). The value in the equation is the y-coordinate.
Thus, the equation derived from the graph is as follows:
Since we are aware that the slope here is negative,
Therefore Our formula is y = -mx + b.

Using the Central Limit Theorem, it is found that the correct option regarding the standard error of the mean is given by:
c. reduce the standard error of the mean to approximately 70% of its current value.
What does the Central Limit Theorem states about the standard error of the mean?By the Central Limit Theorem, the sampling distribution of sample means of size n has standard error \(s = \frac{\sigma}{\sqrt{n}}\).
Doubling n, we have that:
\(s_d = \frac{\sigma}{\sqrt{2n}} = \frac{1}{\sqrt{2}}\left(\frac{\sigma}{\sqrt{n}}\right) = 0.7\left(\frac{\sigma}{\sqrt{n}}\right) = 0.7s\)

In mathematics, a linear inequality is an inequality that involves a linear function. A linear inequality contains one of the symbols of inequality. It shows the data which is not equal in graph form.
The hollow circle in the linear equality shows that the point should be excluded and the line is going towards the positive x-axis.

if x is a continuous random variable on the interval 0, 10
then p(x=5) = f(5) = 1/10 is this correct?
Answers
No, p(x=5) = f(5) = 1/10 is not correct.
How to find if p(x=5) = f(5) = 1/10 is correct?If x is a continuous random variable on the interval [0, 10], then the probability of x taking on any specific value (such as 5) is zero.
This is because there are infinitely many possible values that x can take on within the interval, and the probability of x taking on any one specific value is vanishingly small.
Instead, the probability of x falling within a certain range of values is what is meaningful.
This is typically represented by the probability density function (PDF) of the random variable, denoted as f(x). The probability of x falling within a range [a, b] is then given by the integral of the PDF over that range:
P(a <= x <= b) = integral from a to b of f(x) dx
For a continuous uniform distribution over the interval [0, 10], the PDF is a constant function:
f(x) = 1/10 for 0 <= x <= 10
f(x) = 0 otherwise
Using this PDF, we can find the probability of x falling within a specific range, but the probability of x taking on any one specific value is always zero:
P(x = 5) = 0
So, the statement "p(x=5) = f(5) = 1/10" is not correct for a continuous random variable.

The expected value of the "Buy New" option is 724732.60.
Decision Tree:
To solve the given problem, the first step is to create a decision tree. The decision tree for the given problem is shown below:
Expected Value Calculation: The expected value of the "Buy New" option can be calculated using the following formula:
Expected Value = (Prob. of Prosperity * Payoff for Prosperity) + (Prob. of Recession * Payoff for Recession)
Substituting the given values in the above formula, we get:
Expected Value for "Buy New" = (0.7 * 1,035,332) + (0.3 * -150,000)Expected Value for "Buy New" = 724,732.60
Therefore, the expected value of the "Buy New" option is 724,732.60.

Describe a data set where the mean would be the most appropriate measure of center. Describe a data set where the mean is not the most appropriate measure of center. What measure of center should be used and why
Answers
1. You should use the median to describe the measure of the center of a data set when an outlier is present in a data set.
Having an outlier will skew the mean of the data.
This means it will adjust the average to be smaller or greater than what the actual numbers are showing.
The median should be used as the measure of center in these circumstances.
2) Using a box plot, you can find the range and interquartile range.
What is the range?The range is the distance from the smallest number to the largest. The interquartile range is the distance from the first quartile to the third quartile.
All these values are found on a box plot.
3)The best measure of spread to describe symmetrical data sets is the mean absolute deviation.
This tells us how far on average the numbers are spread out from the mean.
4) See the answer given in 1 for the explanation. An example would be a student who scores 8, 9, 10, 9, 10, and 2 on 6 quizzes.
The mean would be an average of 8, which is not a good number to represent the score this student normally gets.
The median of 9 is a better number to show how this student normally performs.
