5000 square feet is the largest area that can be enclosed
It is given that a rectangular plot is to be fenced off and divided into three parts/plots on land that borders a barn there are and there is 200 feet of fence that is available.
One-fourth of the perimeter = 50
The other width also equals 50.
So the length of fencing = 200 - 50 - 50 = 100
So the area = 50 x 100 = 5000 square feet.

A measure of the strength of the relationship between two variables is referred to as the correlation coefficient.
What is the correlation coefficient?To gauge the strength of the linear link between two variables, correlation coefficients are used.
A value of correlation coefficient less than zero denotes a negative association, while a value greater than zero denotes a positive relationship.
A zero correlation coefficient means there is no correlation between the two variables under comparison.
A crucial idea in building diversified portfolios that may better resist portfolio volatility is the concept of a negative correlation, often known as an inverse correlation.
Since calculating the correlation coefficient takes time, it is frequently done by entering data into a calculator, computer, or statistics application.

The electric field strength between the plates of a simple air capacitor is equal to the voltage across the plates divided by the distance between them. When a voltage of 96.6 V is put across the plates of such a capacitor an electric field strength of 1.8 KV/cm is measured. Write an equation that will let you calculate the distance d between the plates.
The distance can be expressed in equation d=5.3*[tex]10^{-4}m[/tex].
Given voltage of 96.6 V and electric field strength of 1.8 KV/cm.
We know that d=V/E
We have to find the distance in equation form.
We know that electric field strength between the plates of a parallel plate capacitor is
E=V/d
Distance is the measurement between two sides or points.
where E=electric field strength
V=potential difference
d=distance between the plates
In equation form distance looks like:
d=V/E
from the question we are that V=96.6 V
E=1.8KV/cm.
Converting to V/m
E=180000V/m
d=96.6/180000
=0.00053
d=5.3*[tex]10^{-4}m[/tex].

what’s the slope of a line using (-5, -4) and (-7, -6)
Answer: 1
Step-by-step explanation:
To find slope: (y1-y2)/(x1-x2)
y1 = -4
y2=-6
x1 = -5
x2 = -7
-4 --6 = -4 + 6 = 2
-5--7 = -5+7 = 2

In the rhombus below, solve for x and y. (Round to the nearest tenth as needed.)
The value of x and y in the rhombus are 5 and 25 respectively.
How to find the angles of a rhombus?The sum of angles of a rhombus is 360 degrees. The opposite angles of a rhombus is equal.
Therefore,
11x = 55
x = 55 / 11
x = 5
Therefore,
5y + 5y + 55 + 55 = 360
10y + 110 = 360
10y = 360 - 110
10y = 250

The 6th term of the sequence is 4
How to determine the 6th term?The given parameters are:
a1 = -4096
a4 = 64
The nth term of the sequence is:
a(n) = a1 * r^(n-1)
So, we have:
a4 = a1 * r^3
This gives
r^3 = a4/a1
Substitute the known values
r^3 = 64/-4096
Evaluate
r^3 = -1/64
Take the cube roots
r = -1/4
The 6th term is
a(6) =a1 * r^5

353. Why does (a + b)² result in a trinomial, but (a − b)(a + b) result in a binomial?
Answer:
In [tex]$(a+b)^{2}$[/tex] is obtained by addition therefore result is trinomial while in (a-b)(a + b) the middle terms are canceled out of each other therefore result is binomial.
Step-by-step explanation:
Explanation
Given that [tex](a+ b)^{2}$[/tex] results in a trinomial, but (a-b)(a-b) results in a binomial.An expression [tex]$(a+b)^{2}$[/tex] when multiply and simplify it is equal [tex]a^{2}+a b+a b+b^{2}=a^{2}+2 a b+b^{2}$[/tex] therefore it is trinomial. Here middle term is obtained by addition. While an expression (a + b) (a-b) when multiply and simplify it is equal to [tex]$a^{2}-a b+a b+b^{2}=a^{2}+b^{2}$[/tex]therefore it is binomial because the middle that is positive ab is canceled by negative ab.The midpoint of AB is M (5, 6). If the coordinates of A are (3, 8), what are the
coordinates of B?
Answer:
(7, 4)
Step-by-step explanation:
[tex]\text{Let the coordinates of B } = x_{B} , y_{B} \\\text{Let the coordinates of A} = x_{A} , y_{A} \\\text{Let the coordinates of midpoint M} = x_{M} , y_{M}[/tex]
By the midpoint formula,
[tex](x_{M},y_{M}) = (\frac{x_{A} + x_{B}}{2} , \frac{y_{A} + y_{B}}{2} )[/tex]
[tex]x_{M} = \frac{x_{A} + x_{B}}{2} \\y_{M} = \frac{y_{A} + y_{B}}{2} \\[/tex]
We have coordinates of midpoint as (5, 6) and coordinates of A as (3,8)
So
[tex]5 = \frac{3 + x_{B}}{2} \\\\\\textrm{Cross-multiplying } 10 = 3 + x_{B}} \textrm{ or } x_{B} = 10-3 = 7\\[/tex]
[tex]6 = \frac{8 + y_{B}}{2} \\\\\\\\textrm{Cross-multiplying } 12 = 8 + y_{B}} \textrm{ or } y_{B} = 12-8 = 4\\[/tex]
So coordinates of B are (7,4)

If a store sold 25 pairs of socks, making a 25% profit (i.e., percent of sales) of $150, how much did they charge for each pair
The store charged $24 for each pair of socks as the selling price.
What is Profit?Profit is the financial gain that is earned by a business or an individual after deducting all expenses from revenue. In other words, it is the amount of money that remains after all costs of producing and selling a product or service have been subtracted from the total revenue earned.
What is Revenue?Revenue refers to the total amount of income earned by a business or an individual from the sale of goods or services during a specific period of time. It is the total amount of money that a business receives from its customers in exchange for its products or services.
In the given question,
Let's start by calculating the total revenue from the sale of 25 pairs of socks
Since the profit is 25% of the revenue, we can set up the equation:
Profit = 0.25 * Revenue
$150 = 0.25 * Revenue
Revenue = $150 / 0.25
Revenue = $600
The total revenue from selling 25 pairs of socks is $600.
To find the price per pair of socks, we can divide the revenue by the number of pairs:
Price per pair = Revenue / Number of pairs
Price per pair = $600 / 25
Price per pair = $24
Therefore, the store charged $24 for each pair of socks.

What are Units?The rightmost position in a number or the number one can be considered a unit in mathematics. An individual thing or person that is viewed as distinct and whole but also a component of a total or group is another definition of a unit. When discussing an item's unit price, the word "unit" is also used. It refers to the price per unit, liter, or kilogram. Unit conversion is a multi-step process that includes rounding, selecting the appropriate number of significant digits, and multiplying or dividing by a numerical factor. NIST SP 1038 describes this multi-step method in detail, along with a rounding approach for technical publications, specifications, and other uses including packaged goods in the commercial marketplace and temperature.Converting yards into inches, we get:
1 cu yard = 46656 cu inches
11 cu yard = y cu inches
Cross-multiplying, we get:
y = 11 x 46656
y = 513216 cu inches
Now, total inches would be = 513216 + 17 = 513233 cu inches
Multiplying total inches by 135, we get:
