The remainder will be less than k, when the positive integer n is divided by the positive integer k, where k > 1.
What are integers?Positive, negative, and zero are all examples of integers. The Latin word "integer" signifies "whole" or "intact." As a result, fractions and decimals are not included in integers. In this essay, we will learn more about integers, their definition, and their characteristics.
All whole numbers and negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a collection of integers results.
An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion. Integers include things like -5, 0, 1, 5, 8, 97, and 3,043. Z is a set of integers.
Hence, The remainder will be less than k, when the positive integer n is divided by the positive integer k, where k > 1.

If y varies inversely as x and x is 6 when y is 13, what is x when y is 8? a. 9.75 b. 3.69 c. 0.27 d. 6.5
If y fluctuates inversely as x as well as x is 6 if y is 13 then x is 9.75 when y is 8.
Define the term inverse proportion?When one variable declines, the others also decline in the same ratio. When two variables move in opposite directions, one variable reduces as another increases and the other increases as another variable lowers, the variables are said to be inversely proportional. Direct proportion is in opposition to it.Inverse variation is demonstrated by the following equation when two quantities, x and y, are in inverse proportion:-
x y = x1 y1
Now, if x is 6 when y is 13 and y varies inversely with x, then at y =8,
Thus,
x × 8 = 6× 13
x = (6×13)/8
x = 9.75
As a result, if y varies inversely as x as well as x is 6 if y is 13 then x is 9.75 when y is 8.

Step-by-step explanation:
Drag and drop the answer into the box to match each point to its coordinates.
The required Co-ordinates are A(-0.5, -0.25), B(-2.5, 1.5) and C(0.25, 0.5).
How to calculate points on the graph?To diagram a point, first find its situation on the x-axis, then track down its area on the y-hub, lastly plot where these meet. The middle place of the chart is known as the origin and is composed as the point (0, 0) since it's situated at the no point on the x-axis and the no point on the y-axis.
What are Co-ordinates ?The distance of a point from y-hub scaled with the x-hub is called abscissa or x direction of the point. The distance of a point from x-pivot scaled with the y-hub is called ordinate. The abscissa and ordinate all together are called organizes.
According to question:Now we find the co-ordinates of points on the graph,
Point A(-0.5, -0.25)
Point B(-2.5, 1.5)
And
Point C(0.25, 0.5)
Thus, required points are A(-0.5, -0.25), B(-2.5, 1.5) andC(0.25, 0.5).

Some nations require their students to pass an exam before earning their primary school degrees or diplomas. A certain nation gives students an exam whose scores are normally distributed with a mean of 414141 points and a standard deviation of 999 points. Suppose we select 222 of these testers at random, and define the random variable ddd as the difference between their scores. We can assume that their scores are independent. Find the probability that their scores differ by more than 151515 points.
The required probability that their scores differ by more than 15 points is 0.99807.
As stated in the question, a specific country administers an exam to students with scores that are regularly distributed with a mean of 41 points and a standard deviation of 9 points. Assume we randomly select two of these testers and define the random variable d as the difference in their scores.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Z = x - μ / σ
Z = 15 - 41 / 9
Z = -2.88
Now,
P(x > 15) = P (z > -2.88)
= 0.99807

Ratio of the area of a square inscribed in a semicircle with radius 'r' to the area of a square inscribed in a circle with radius 'r' is equal to 2: 5.
As given in the question,
Let ABCD be the square with side 'a' inscribed in a semicircle with radius 'r'.
'O' be the center of the semicircle.
'M' be the midpoint of AB such that MB = a/2
Join OM, OB and OM ⊥ AB
OB = r

Let PQRS be the inscribed in a circle with side 'x'
Diagonal of the square inscribed in a circle = 2r
In ΔPQR,
PR = diagonal

Given,
A quiz consists of 24 questions. each question has 4 answer choices with exactly one correct answer. a student is completely unprepared for the quiz, so he guesses on all 24 questions.
Here we need to find how many questions should the student expect to answer correctly.
While we looking into the given question, we have identified that the total number of questions is 24.
Number of options = 4
So, the probability of getting correct answer = 1/4 = 0.25
The probability of getting incorrect answer is,

What is the slope-point form of the line?
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
A line goes through the point (-1, 1) and (0,-3)
so the slope of the given line would be:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-3-1}{0-(-1)}\\\\m=-4[/tex]
And we have to find the line which passes through the point (-4, -3) and the required line is perpendicular to the given line.
As we know the product of slopes of perpendicular lines is -1.
So the slope of the required line would be = 1/4
By using a slope-point form of the line, we get

What is the common difference of the arithmetic sequence?
Can you think of any other mathematical relationship that exhibits a common difference between numbers?
Answer:

In the first sequence, subtracting the previous term from each term starting from the second one gives these values: (0, 6, 12, 18, 24, . . .) is an arithmetic sequence.
How to find the common difference in the arithmetic sequence?
Common difference = second term - first term
The difference between the terms is constant. This sequence is an arithmetic one, with the common difference being 6.
Common difference = 6.
Just by looking at the terms in the second sequence,
(1, 6, 36, 216, 1,296, . . .), the difference between the consecutive terms is not common. This sequence is not an arithmetic sequence because it is based on the multiply by 6 rule.
Like arithmetic sequences, linear equations show a common difference between numbers.
Answer: In the first sequence, subtracting the previous term from each term starting from the second one gives these values:
6 – 0 = 6, 12 – 6 = 6, 18 – 12 = 6, and 24 – 18 = 6.
The difference of the terms is constant. This sequence is an arithmetic one, with the common difference being 6.
Just by looking at the terms in the second sequence, (1, 6, 36, 216, 1,296, . . .), it’s clear that the difference of the consecutive terms is not common. This sequence is not an arithmetic sequence because it is based on the multiply by 6 rule.

Using simple mathematical operations, we know that we will require 1436 bricks to construct a brick wall.
What are mathematical operations?A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.
There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.
In mathematics, addition, subtraction, multiplication, division, and modular forms are the five basic operations.
So, we know that:
A brick wall's measurements are provided by:
14.5 feet in length
Size: 0.5 feet wide
5.5 feet tall
Brick dimensions are provided by:
6 inches in length
4-inch width
2 inches tall
The number of bricks must be determined:
Thus, the number of bricks is provided by:
Number of bricks = Volume of brick wall/Volume of brick
Number of bricks = 14.5 * 5.5 * 0.5 * 12 * 12 * 12/6 * 4 * 2
Number of bricks = 1435.5
Number of bricks = 1436
