You can mail small things weighing 70 pounds or less to any location in the US for a set price using USPS Small Flat Rate boxes. The cost of a USPS Small Flat Rate package is only $8.45.

The United States Postal Service (USPS), often known as the Post Office, U.S. Mail, or Postal Service, is a separate executive branch agency that is in charge of delivering postal service across the United States, including its associated states and insular territories.

It is one of the few governmental organizations that the US Constitution expressly grants authority to. 516,636 career employees and 136,531 non-career employees work for the USPS as of 2021.

The first postmaster general of the United States Postal Service, Benjamin Franklin, was appointed in 1775 during the Second Continental Congress. He also held a comparable role for the colonies of the Kingdom of Great Britain.

With the passing of the Postal Service Act in 1792, the Post Office Department was established.

An n x 11 matrix can have a maximum of n different eigenvalues, whereas a 2 x 2 matrix can only have a maximum of two. Below, there is a detailed explanation of this.

a collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix are the integers. In addition to numerous mathematical disciplines, matrices find extensive use in the fields of engineering, physics, economics, and statistics.

The study of matrices is the main focus of the mathematical field known as matrix theory. It started out as a branch of linear algebra but quickly expanded to cover topics in graph theory, algebra, combinatorics, and statistics.

solution of a 2 x 2 matrix is in given form:

|A - λI| = 0

here,

A =  eigenvalue

I = identity matrix

now

|A - λI| = (a11 - λ)

(a22 - λ) - a12a21 = 0

the solutions of above equation are  2 x 2 matrix's eigenvalues.

just like this, a matrix of size n by n may have up to n different eigenvalues as its characteristic equation is a polynomial of nth degree with up to n roots (i.e. n eigenvalues). all due to the equation form: |A - I| = 0, where A is an eigen and I is an identity matrix.

by expanding the determinant:

|A - I| =  (-1)

having coefficients c1, c2,..., cn, having sum = zero.

which is nth degree polynomial equation consisting of n possible solutions, that are basically n x n matrix's eigenvalues .

The free throw accuracy of these players can be ranked from lowest to highest as Haller, Smith, Ballard, and Dennis.

What is a fraction?

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, or three-quarters.

To rank the free throw accuracy of these players from lowest to highest, we need to compare the fraction of free throws made to the total number of free throws taken by each player.

The fraction of free throws made to the total number of free throws taken is called the free throw percentage.

The free throw percentage for each player can be calculated by dividing the number of free throws made by the number of free throws taken and expressing the result as a decimal.

For example, the free throw percentage for Smith can be calculated as follows:

Free throw percentage = 13/19 = 0.68

We can use this same method to calculate the free throw percentage for the other players:

Haller: Free throw percentage = 12/20 = 0.6

Dennis: Free throw percentage = 14/17 = 0.82

Ballard: Free throw percentage = 17/22 = 0.77

Based on these calculations, the free throw accuracy of these players can be ranked from lowest to highest as follows:

Haller: Free throw percentage = 0.6

Smith: Free throw percentage = 0.68

Ballard: Free throw percentage = 0.77

Dennis: Free throw percentage = 0.82

Hence, the free throw accuracy of these players can be ranked from lowest to highest as Haller, Smith, Ballard, and Dennis.

The speed of a cyclist rode 3.75 miles in 0.3 hours is 0.36 hours.

Given that, a cyclist rode 3.75 miles in 0.3 hours.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

A) We know that, speed =Distance/Time

Now, speed =3.75/0.3

= 12.5 miles per hour

B) Here, distance =4.5 miles and rate =12.5 miles per hour

Now, 12.5 =4.5/Time

⇒ Time =4.5/12.5

As per the concept of compound interest, it take 62.915 years for the account to earn $7500

Compound interest:

The general formula to calculate the compound interest is written as,

A = P(1 + r/n)^nt

where

A = Accrued amount (principal + interest)

P = Principal amount

r = Annual nominal interest rate as a decimal

n = number of compounding periods per unit of time

t = time in decimal years;

Given,

Compounding frequency = Quarterly

Interest rate = 1.75%

Opening balance = $2500

Final amount = $7500

Now, we have to calculate the time time for the person to achieve the final amount,

First, convert R as a percent to r as a decimal

r = R/100

r = 1.75/100

r = 0.0175 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(7,500.00/2,500.00) / ( 4 × [ln(1 + 0.0175/4)] )

t = ln(7,500.00/2,500.00) / ( 4 × [ln(1 + 0.004375)] )

t = 62.915 years

Therefore, the  time required to get a total amount of $7,500.00 with compounded interest on a principal of $2,500.00 at an interest rate of 1.75% per year and compounded 4 times per year is 62.915 years.

let

Number of students tickets = x

Number of adults tickets = y

x + y = 461

3x + 4y = 1624

From (1)

x = 461 - y

Substitute into (2)

3x + 4y = 1624

3(461 - y) + 4y = 1624

1383 - 3y + 4y = 1624

- 3y + 4y = 1624 - 1383
