I came across a question in the pigeonhole principle that – Let S be a set of n integers. Show that there is a subset of S, the sum of whose elements is a multiple of n by pigeonhole.
How do I solve this question??

Answers

Answer 1

In this case the difference is a multiple of n and as you see the difference is still a sum of some integers subset  from 1 to n

What is subset?

If every element of set A is also an element of set B, then set B is a superset of set A and set A is a subset of set B. A and B could be equal; if they are not, then A is a legitimate subset of B. Include refers to the property that one set is a subset of another.

Consider the set{a1,a1+a2,a1+a2+a3,...,a1+a2+...+an}You have a set of n elements .If all remainders in dividing by n, are different, one of the remainders is 0 and we are done .Otherwise two remainders are the same.

In this case the difference is a multiple of n and as you see the difference is still a sum of some integers from 1 to n However I think it would be natural to consider the set{0,a1,a1+a2,a1+a2+a3,…,a1+a2+⋯+an}of n+1 elements, so that there is only one case instead of two.

What is a Parallelogram?

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The four types are parallelograms, squares, rectangles, and rhombuses

Properties of Parallelogram

Opposite sides are parallel

Opposite sides are congruent

Opposite angles are congruent.

Same-Side interior angles (consecutive angles) are supplementary

Each diagonal of a parallelogram separates it into two congruent triangles

The diagonals of a parallelogram bisect each other

Given data ,

Identifying the domains and ranges for particular functions will be practiced in this session. Be aware that while choosing domains and ranges, we must take into account what is realistically feasible or significant, such as the number of tickets sold and the year in the previous horror movie example. Additionally, we must think about what is allowed mathematically. As an illustration, if the domain and range are real numbers, we cannot include any input value that causes us to take the even root of a negative number. Alternatively, in a function denoted by a formula, we are not allowed to include any input value whose domain would cause us to divide by 0.The interval notation, which describes a set of numbers by using values enclosed in brackets, can be used to express the domain and range. When notating intervals, we use square brackets to denote inclusion of the endpoint in the set and parentheses to denote exclusion of the endpoint or unbounded intervals.

the expression for the apparent nth term an of the sequence is 3*2^(n-1) + 1.

the expression for the apparent nth term an of the sequence is 3*2^(n-1) + 1.

an = 3*2^(n-1) + 1

The sequence appears to follow a pattern of 3*2^n + 1

Therefore, the expression for the apparent nth term an of the sequence is 3*2^(n-1) + 1. (Note that n begins with 1, so we subtract 1 from n.)

The nth term an of the sequence 3, 10, 29, 66, 127, can be expressed as 3*2^(n-1) + 1. This follows a pattern of multiplying the previous term by 2 and then adding 1. For example, the second term 10 is 3*2^1 + 1, and the third term is 3*2^2 + 1. This pattern continues for each term in the sequence, which begins at n=1.

4. Repeat and sketch the graph for A = 1, B = 2.

Is there any relationship to what you found in part (2)?
5. Explain what you have discovered from completing this activity using details and examples.

Answers

It is revealed through completing the task that the graph of y = sin x + cos x is periodic, having a maximum point at x 0.94 and y 2.24. We've also noted that changing the values of A and B causes the graph to move to the left, with the highest point at x 0.44 and y 2.84. This demonstrates that the ratio of A and B determines the greatest point of the graph.

What does this activity shows?

This activity has demonstrated the effect of changing the coefficients of sine and cosine functions when combined. For example, when A and B are both 1, the graph of y = sin x + cos x creates a wave-like shape with a maximum point at (π/2, 2). When A is increased to 2 and B is kept at 1, the maximum point moves to the right and increases in y-value to (2π/3, 3). When B is increased to 2 and A is kept at 1, the maximum point moves to the left and increases in y-value to (π/3, 3). This shows that when the coefficient of the sine term is increased, the maximum point moves to the right, and when the coefficient of the cosine term is increased, the maximum point moves to the left. This also shows that the maximum point of the graph y = A sin x + B cos x increases in y-value as A and B increase.

Finding the zeros of a polynomial

Answers

To find the zeroes (also known as roots) of a polynomial, we can set the polynomial equal to zero and solve for the variable. The solutions to the equation are the zeroes of the polynomial.

What is a polynomial?

A polynomial is a mathematical expression that is a sum of powers in one or more variables (indeterminates) with non-negative integer exponents and real or complex coefficients. The degree of a polynomial is the highest power of the variable. For example, the polynomial 3x^2 + 2x - 1 is a polynomial of degree 2, and the polynomial 5 is a polynomial of degree 0.

To find the zeroes (also known as roots) of a polynomial, we can set the polynomial equal to zero and solve for the variable. The solutions to the equation are the zeroes of the polynomial.

For example, to find the zeroes of the polynomial 3x^2 + 2x - 1, we set the polynomial equal to zero:

3x^2 + 2x - 1 = 0

Then we can factor the polynomial or use the quadratic formula to find the solutions:

x = (-2 +/- sqrt(2^2 - 43(-1)) ) / (2*3) = (-2 +/- sqrt(4 + 12))/6 = (-2 +/- sqrt(16))/6 = (-1 +/- sqrt(4))/3 = (-1 +/- 2i)/3

The zeroes of the polynomial 3x^2 + 2x - 1 are x = (-1 + 2i)/3 and x = (-1 - 2i)/3, which are complex numbers.

Hence, To find the zeroes (also known as roots) of a polynomial, we can set the polynomial equal to zero and solve for the variable. The solutions to the equation are the zeroes of the polynomial.

Answers

Nick has failed to meet the condition that n p hat greater-than-or-equal-to 10 and n (1 minus p hat) greater-than-or-equal-to 10.

In order for the Central Limit Theorem to be applied and for the sample proportion to be approximately normally distributed, the sample size must be at least 30. This means that the sample size must be large enough so that the sample proportion of healthy breakfast eaters (p hat) and the sample proportion of non-healthy breakfast eaters (1-p hat) are both greater than or equal to 10. In this case, since the sample proportion of healthy breakfast eaters is 20/25 = 0.8, the sample proportion of non-healthy breakfast eaters is 5/25 = 0.2. Since 5 is less than 10, this condition is not met, and Nick cannot construct a confidence interval for p.

Answers

Answer: y/x = k, where k is the constant of proportionality.

Step-by-step explanation:

The proportional connection is represented by the linear equation y equals two-thirds times x.

A proportionate connection is a two-variable relationship in which one variable is a constant multiple of the other. In other words, if y is proportional to x directly, then y = kx for some constant k. This can alternatively be written as y/x = k, where k is the proportionality constant.

The proportionate connection is represented by the linear equation y = 2/3x.

It demonstrates a direct connection since the coefficient of x (2/3) is constant and there is no constant term (y-intercept) to break the proportionality.

The other equations do not have a proportionate connection because they feature a variable coefficient or a constant term.

Therefore, the conclusion is that we reject H0. The data suggests that the difference in average tension bond strengths is greater than 0.

For this one-tailed hypothesis test, we must reject the null hypothesis (H0: m1 - m2 = 0) if the test statistic is greater than 2.33. Our test statistic value is 2.76, which is greater than 2.33, so we reject H0. This indicates that the data suggests that the difference in average tension bond strengths is greater than 0. In other words, the polymer latex modified mortar has a higher tension bond strength than the unmodified mortar.

For every m ≥ 2, let Q(m) be the least positive integer with the following property: For every n ≥ Q(m), there is always a perfect cube k^3 in the range n < k^3 ≤ m.n Find the remainder when Σ 2017 m=2 Q(m) is divided by 1000.

Answers

The remainder when the sum Σ 2017 m=2 Q(m) is divided by 1000 is 448.

448

Q(m) is the least positive integer such that for every n ≥ Q(m), there is a perfect cube k^3 in the range n < k^3 ≤ m.

For example, Q(2) = 1 since 1^3 is in the range 1 < 1^3 ≤ 2.

Similarly, Q(3) = 2 since 2^3 is in the range 2 < 2^3 ≤ 3, and Q(4) = 3 since 3^3 is in the range 3 < 3^3 ≤ 4.

We are asked to find the remainder when the sum Σ 2017 m=2 Q(m) is divided by 1000.

To do this, we can calculate the sum of the first 2017 terms of the sequence.

Q(2) + Q(3) + Q(4) + ... + Q(2017) = 448

Since 448 is divisible by 1000, the remainder when the sum is divided by 1000 is 0.

The remainder when the sum Σ 2017 m=2 Q(m) is divided by 1000 is 448.

(x 1)2

Answers

The equation for the parabola is: (x - 1)^2 = 4(y - 5). The vertex of the parabola is located at (1, 5) and the focus is at (1, 1). The equation describes a parabola that opens upward, and is symmetrical about the y-axis.

The equation for the parabola is: (x - 1)^2 = 4(y - 5). This equation describes a parabola with its vertex located at (1, 5) and its focus at (1, 1). The parabola is symmetrical about the y-axis and opens upward. This means that the base of the bulb is at (1, 5) and the top of the bulb is at (1, 1). To get the equation for the parabola, we need to subtract the x-coordinate of the vertex from the x-coordinate of the focus, which gives us 1. We then square this number, giving us 1. We then subtract the y-coordinate of the vertex from the y-coordinate of the focus, giving us 4. We then multiply this number by the squared number from before, giving us 4. The final equation is then (x - 1)^2 = 4(y - 5).
