yards of thread to make 4⁄6
of a sock. How many yards of thread will it take to
make an entire sock?
The yards of thread that will take to make an entire sock will be 3 3/4 yards.
How to calculate the fraction?A fraction simply means a piece of a whole. In this situation, the number is represented as a quotient such that the numerator and denominator are split. In this situation, in a simple fraction, the numerator as well as the denominator are both integers.
In this case, 2 1/2 yards of thread to make 4 /6
of a sock.
The yards of thread that will take to make an entire sock will be:
= 2 1/2 ÷ 4 / 6
= 5 / 2 × 6/4
= 30 / 8
= 15 / 4
= 3 3/4 yards.

What is polynomials?
Using variables and coefficients, polynomials are algebraic expressions. The term "indeterminates" is sometimes used to describe variables. The terms Poly and Nominal, which together signify "many" and "terms," make up the word polynomial. When exponents, constants, and variables are combined using mathematical operations like addition, subtraction, multiplication, and division, the result is a polynomial (No division operation by a variable). The expression is categorized as a monomial, binomial, or trinomial based on the number of terms it contains.
(-x^4+7x^3+2x+3)/ (x-3)
=-x² + 4x² + 12x + 38 + 117/(x - 3)
Hence the simplest form of the given expression is px=-3x^3-2x²-6x-16,r(x)=-45, and q(x)=x-3.

The midpoint of AB = ([?], [])
When A point is (3, 1) and B point is (-1 , -1), the midpoint of AB is ( 2, 1) . The line segment's exact midway is where the midpoint is located.
what is mid point ?The term "midpoint" describes a point along a line that connects two points. The midway is situated between the two reference locations, which are the line's ends. The line connecting these two places is split into two equally sized sections by the middle. A point that splits a line segment into two equal halves is known as the midway. In other words, the line segment's exact midway is where the midpoint is located. It is demonstrably true that the middle of a number line has the same value as the average of any two matching places on the line.
given
midpoint of AB is equal to (x2 - x1) / 2 (3 + 1) / 2 = 2.
the midpoint of AB is 1
the midpoint of AB is (y2 - y1)/2
= (1+1)/2.

A vertical line in geometry is one that crosses the page from top to bottom.
What is meant by horizontal and vertical segments?A vertical line in geometry is one that crosses the page from top to bottom. Its cousin is the horizontal line that spans the page from left to right. A horizontal line and a vertical line are perpendicular.
Businesses utilize segmentation as a marketing strategy to focus on a certain market segment or type of customer. While vertical segmentation sharpens your marketing emphasis to target customers in a smaller demographic, horizontal segmentation entails offering a product to a broad range of consumers.
A horizontal object is one that is perpendicular to the horizon. Due to the fact that vertical is the polar opposite of horizontal, anything that forms a 90° (right angle) with either the horizontal or the horizon is referred to as vertical. This means that the horizontal line is one that crosses from left to right. Mathematical applications of the horizontal and vertical.

the volum of the wood in a tree varries directly as height and the square of length
Answer:
The volume of wood in a tree varies directly with the height and the square of the length of the tree. This means that if we increase the height of the tree, the volume of wood in the tree will also increase, and if we increase the length of the tree, the volume of wood will increase by the square of that increase.
This relationship can be expressed mathematically as:
V = khl^2
Where V is the volume of wood in the tree, h is the height of the tree, l is the length of the tree, and k is a constant of proportionality.
This relationship is based on the assumption that the cross-sectional area of the tree remains constant, and that the volume of wood in the tree is directly proportional to the height and the square of the length of the tree.

A large hospital has an average of 7 fatalities in a week. Using the Poisson model, what is the probability that this week it has 7fatalities? The probability that the hospital has 7 fatalities this week is
The probability that the hospital has 7 fatalities this week is approximately 0.0199
The probability that the hospital has 7 fatalities in a week, given an average of 7 fatalities per week, can be calculated using the Poisson distribution. The Poisson distribution is a discrete probability distribution that models the number of events (in this case, fatalities) that occur in a fixed interval of time (in this case, a week) with a certain average rate (in this case, 7 fatalities per week). The probability of k events happening in a given interval of time is given by the following formula:
P(k;λ) = (e^(-λ))*(λ^k)/k!
Where λ is the average number of events per interval of time and k is the number of events we are interested in.
In this case, we are looking for the probability that there are 7 fatalities this week, given that the average number of fatalities per week is 7. So we can plug in the values into the equation:
P(7;7) = (e^(-7))(7^7)/7! =0.149

What are vertically opposite angles?
Opposite angles are the angles directly opposite each other where two lines cross. The intersection point is called the vertex, which is where the lines connect to form the angle. Opposite angles are also called vertical angles. In this instance, the word vertical refers to the vertex as opposed to direction.
We have given,
Two opposite angles:
(6x + 1)°, and 67°
So, We need to determine the value of x.
We know that the property of opposites angles, which the opposite angles are equal to each other.
So, (6x + 1)° = 67°
By calculating further:
6x + 1 = 67
6x = 67 - 1
6x = 66
x = 66/6
x = 11

Therefore , the solution to the given problem of function comes out to be ss a result, Rolle's Theorem remains true.
What does the word function mean?Mathematics deals with numbers and their variants, formulae and associated structures, geometries and their areas, and locations where they might be found. The term "function" describes the connection between a group of input, of which each has a corresponding output. A function is an association among inputs and outputs where each input results in a single, unique output. A realm as well as a codomain, or scope, are assigned to each function. Functions are typically denoted by the letter f. (x). The input is an x. On activities, one-to-one activities, many-to-one functions, within operations, and on functions are the four main categories of functions that are available.
Here,
Consider
f(-1)=1-[tex](-1 )^{\frac {2}{3}}[/tex]=0
and f(1)=1-[tex](-1 )^{\frac {2}{3}}[/tex]=0
So, f(-1)= f(1) (1)
As a result of differentiating f(x) with regard to x, we now have
f'(x)= -2 / 3
Consequently, f'(0) is false.
So, at 0inleft (-1,1 ), f cannot be deduced.
Therefore, the given function in the range (-1,1) does not satisfy Rolle's theorem.
As a result, no c exists in (-1,1) for which f'(c )=0 even though f(-1)=f(1 ).
As a result, Rolle's Theorem remains true.
