The equation could be described by "the product of three and the reciprocal of four divided by three"
What is a fraction?Is a number that expresses the portion of some number over a total. The number that expresses the portion is known as the numerator and the number that expresses the total is known as the denominator.
To solve this problem we must perform the corresponding algebraic operations with mixed fraction.
Original equation:
4 / (1 1/3)
A mixed operation is solved as follows:
For the denominator: the same denominator is placed.
For the numerator:
The value of the denominator is multiplied by the integer component.The result is added to the numerator of the fraction.We transform the mixed fraction into improper fraction and we have:
1 1/3 = [(3*1) + 1)] /3 = [3+ 1] /3 = 4/3
Now, describing the equation with the improper fraction we get:
4 / (4/3)
Solving the division with fractions we have:
(4*3) / 4
This means that "the product of three and the reciprocal of four divided by three"

Two cards are selected, without replacing the first card, from a standard deck. Find the probability that both cards are sevens.
The probability that both cards are sevens is 0.0044
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
There are 52 cards, 4 are sevens.
So the probability of picking the first 7 is 4/52.
If you don't replace the card, then there are only 51 cards left, 3 of which are sevens.
So the probability of picking a seven on the second draw is 3/51.
The probability of picking sevens on both draws is:
P(picking two sevens) = (4/52)·(3/51) =0.076*0.058=0.0044

What is the range of the function FX =- 2 6x )+ 3?.
The range of the function FX = -2(6x) + 3 is [-3, +∞).
First, let's simplify the equation.
FX = -2(6x) + 3
FX = -12x + 3
To determine the range of the function, start by graphing the equation.
The graph will be a line with a slope of -12 and a y-intercept of 3.
To find the range, we need to determine the y-values of the graph as x-values increase. Since the slope is negative, the y-values will decrease as x-values increase.
The range of the function is all real numbers less than or equal to 3.
Therefore, the range of the function FX=-12x+3 is all real numbers less than or equal to 3.

Step-by-step explanation:
Why does the operations subtraction and division Cannot be applied by commutative property and associative property?.
The commutative property and associative property do not hold for subtraction and division, as the end results are completely different after changing the order of numbers.
The commutative property deals with the arithmetic operations of addition and multiplication. It means that changing the order or position of two numbers while adding or multiplying them does not change the end result.
For example, 4 + 5 gives 9, and 5 + 4 also gives 9. The order of two numbers being added does not affect the sum. The same concept applies to multiplication too.
Thus, The commutative property and associative property do not hold for subtraction and division, as the end results are completely different after changing the order of numbers.

How do you use the zero product property to solve a quadratic equation in factored form?.
Quadratic equations in factored form can be solved by using the Zero Product Property, which states that if the product of two numbers equals zero, then at least one of the values must also equal zero.
The Zero Product Property can be used to resolve any factored quadratic equation, such as (a + b)(a b) = 0. In accordance with the zero product property, if a+b=0, then either an or b must also be equal to zero. This essential characteristic allows us to solve equations like (x+2)(x-5)=0.
The zero product property states that if two quantities are added together and the result is zero, then one or both of the individual quantities must also be zero. You can solve this problem by rewriting it as (x + 3) (2 x 1) = 0.

How to calculate the circumcenter of the triangle ?The point of concurrency of the lines perpendicular to the sides of a triangle is known as the circumcenter of the triangle. To find the circumcenter of a triangle with vertices at (x1, y1), (x2, y2), and (x3, y3), you can use the following formula:
x = (x1 + x2 + x3) / 3
y = (y1 + y2 + y3) / 3

Why is equivalence important in maths?.
Equivalence relations are important in maths because of the following parts,
The fundamental theorem of equivalence relations is basic theorem.In integration theoryIn case of equivalent fractionA relation R on a set A is called an equivalence relation if and only if the relation R is recursive, symmetric, and transitive. An equivalence relation is a relation on sets, and is generally represented by the symbol “~”. For example: "Equal to (=)" is the equivalence relation on any set of numbers A for all elements a, b, c ∈ A,
Reflexive: a = a ,
Symmetric: a = b ⇒ b = a and
Transitive: a = b, b = c ⇒ a = c.
This means that (=) is recursive, symmetric, and transitive. Equivalence relations are used in several areas of mathematics.
In integration theory, functions are considered "equal" if they differ only in a small set. in some respects. If the function is not identified in this way, some commonly used standards conditiondoes not satisfy || f || = 0 <=> f=0.

how much water do you add to make this concentration? 25% sugar syrup using 15 g sugar
The amount of water to add is 45 grams
How to determine the amount of water to addFrom the question, we have the following parameters that can be used in our computation:
Sugar = 15 grams
Proportion of syrup = 25%
So organizing the information given in the statement we have that:
25% sugar syrup means it has 25% sugar and 75% waterAmount of sugar = 15g = 25%In this way, we can calculate the missing value for this percentage as:
25% of x = 15 grams
Express as decimal
So, we have
0.25 * x = 15
Divide both sides by 0.25
x = 60
This means that the total amount is 60 grams
If the syrup contains 25% of sugar, then 75% would be water (assume no other item is present)
So, we have
Water = 75% * 60g
Water = 45g
Hence, the amount is 45 grams

Writing linear equations given two points can be a useful skill when graphing linear equations.
Write a linear equation that passes through the given two points?To write a linear equation given two points, you need to first find the slope of the line. You can do this by finding the change in the y-value and dividing it by the change in the x-value. From there, you can use the slope to solve for the y-intercept and write the equation.For example, if the two points are (3, 4) and (0,5), you would find the slope by calculating the change in the y-value (5-4 = 1) and dividing it by the change in the x-value (0-3 = -3).The slope would then be 1/-3, which can be simplified to -1/3. To solve for the y-intercept, you can plug in one of the points and solve for b. In this case, you would plug in (3, 4) and solve for b, giving you b = 5. Now that you have the slope and y-intercept, you can write the equation as y = -1/3x + 5.y = -1/2xy = 5/3x + 5/3y = 3/5x + 1y = -1/2x - 2y = 6/5x + 5y = -4/4x - 8y = -3/5x - 7/5y = -2x - 4y = 5/6x + 7y = -1/2x + 4To learn more about linear equation refer to:
