How many years after the Revolutionary War were packet ships used?
Answers
Around 30 to 40 years after the Revolutionary War packet ships used by people and mail were transported across the Atlantic Ocean by packet ships.
Since they transported postal packets, which were sealed sacks carrying letters and documents, they were known as "packet ships." Packet ships were also employed in commercial commerce to move commodities like sugar, tobacco, and textiles.
During and after the Revolutionary War, which lasted from 1775 to 1783, packet ships were employed. In the decades that followed the war, as transatlantic trade and travel rose, the usage of packet ships continued to rise.
Steamships, which were quicker and more effective, had essentially taken the place of packet ships by the middle of the 19th century.

A factory makes 300 tarts every day. The tarts are apple tarts or lemon tarts. Each day a sample of 15 tarts is randomly selected for quality checks.
The proportion of apple tarts in this sample is the same as the proportion of apple tarts made that day.
On Monday it was calculated that exactly 6 apple tarts were needed in the quality checks sample.
a) Work out the number of apple tarts that were made on Monday.
On Tuesday, the number of lemon tarts needed in the quality checks sample is 4 correct to the nearest whole number.
A tart is taken at random from the 300 tarts made on Tuesday.
b) Work out the lower bound of the probability that the tart is a lemon tart.
Answers
a)On Monday, 120 apple tarts were made.
b) The lower bound of the probability that the tart taken at random on Tuesday is a lemon tart is approximately 0.267.
a) To determine the number of apple tarts made on Monday, we can set up a proportion based on the sample of 15 tarts and the known proportion of apple tarts.
Let x be the number of apple tarts made on Monday.
The proportion of apple tarts in the sample is given by:
\(6/15 = x/300\).
Cross-multiplying and solving for x, we get:
\(6 * 300 = 15 * x,\)
\(1800 = 15x\),
\(x = 1800/15\),
\(x = 120\).
b) To find the lower bound of the probability that the tart taken at random on Tuesday is a lemon tart, we need to consider the minimum number of lemon tarts needed in the quality checks sample.
The number of lemon tarts needed is 4 (correct to the nearest whole number).
To calculate the lower bound of the probability, we assume that exactly 4 lemon tarts were needed, meaning the remaining 11 tarts in the sample are apple tarts.
The probability of selecting a lemon tart from the 300 tarts made on Tuesday is:
\(4/15 ≈ 0.267\) (rounded to three decimal places).

Answers
The distance value of x is (2+√2)/5 or (2-√2)/5.
Given the coordinates of two points (x, 2) and (1, 3).We need to find x so that the distance between (x, 2) and (1, 3) is √5.Distance formula: The distance between the points (x1, y1) and (x2, y2) is given by √[(x2 - x1)² + (y2 - y1)²].Hence, the distance between (x, 2) and (1, 3) is √[(1 - x)² + (3 - 2)²] = √[(1 - x)² + 1] = √5. Square both sides of the equation.√[(1 - x)² + 1]² = 5Simplify the equation by expanding the left-hand side. (1 - x)² + 1 = 5(1 - x)² + 1 = 5x² - 10x + 6The equation obtained is a quadratic equation which can be written in the form:ax² + bx + c = 0Where, a = 5, b = -10, and c = 6.To solve this quadratic equation, we can either use the quadratic formula or factorization.x = (2±√2)/5Therefore, x = (2+√2)/5 or (2-√2)/5Hence, the value of x is (2+√2)/5 or (2-√2)/5.

How to represent the area and perimeter of a sandbox with an equation?The dimension of a sand box can be represented as (x + 2) inches and (x + 1) inches. The value of the area in square inches of the sandbox is equal to the value of the perimeter of the sandbox in inches.
Therefore, the equation that can be used to find the value of x can be express as follows:
Hence,
area of the sandbox = (x + 2)(x + 1)
area of the sandbox = x² + x + 2x + 2
area of the sandbox = x² + 3x + 2
Perimeter of the sandbox = 2(x + 2 + x + 1)
Perimeter of the sandbox =2(2x + 3)
Perimeter of the sandbox = 4x + 6
Therefore,
x² + 3x + 2 = 4x + 6
x² + 3x - 4x + 2 - 6 = 0

Answers
Based on the provided equation, no definitive conclusion can be drawn about the stability of the system without additional information or analysis.
To determine the stability of a system, further analysis is required. The given equation is a linear ordinary differential equation relating the derivatives of the output variable y and the input variable u. The coefficients in the equation, 6 and -7 for dy/dt and y, respectively, as well as 4 and -3 for du/dt and u, do not provide sufficient information to determine stability.
Stability analysis typically involves assessing the behavior of the system's response over time. Stability can be classified into several categories, including stable, unstable, critically damped, or marginally stable. However, in this case, the given equation does not provide the necessary information to make any definitive conclusion about the stability of the system.
To assess stability, one would typically examine the characteristic equation, eigenvalues, or transfer function associated with the system. Without such additional information or analysis, it is not possible to determine the stability of the system solely based on the given equation.
The provided equation does not provide enough information to draw a conclusion about the stability of the system. Further analysis using techniques like eigenvalue analysis or transfer function analysis would be necessary to determine the stability characteristics of the system.

A businessman takes the 8:00 a. M. Train to work on 20 days in a month. He is surprised when the train arrives late in New York on 3 of the 20 days. Should he be surprised? Describe how you would carry out a simulation to estimate the probability that the train would arrive late on 3 or more of 20 days if New Jersey Transit’s claim is true. Do not perform the simulation
Answers
No, he should not be surprised. New Jersey Transit claims that the 8:00 a.m. train arrives late in New York on an average of 15 days a month. This means that the probability of the train arriving late on 3 or more days in a month is relatively high.
To estimate this probability, one can carry out a simulation. First, generate a list of 20 random numbers between 0 and 1. Each number represents a day in the month and the probability of the train arriving late. Next, assign each number a value of 1 if it is less than or equal to 0.15 (the probability of the train arriving late on any given day), and 0 if it is greater than 0.15. This represents the arrival status of the train on each day.
Finally, sum the list of numbers to obtain the total number of days the train arrived late. Repeat this process multiple times and calculate the probability of the train arriving late on 3 or more of the 20 days.

The sum of two numbers is -5. The difference is
13. What is the smaller number?
Answers
Answer:
The smaller number is -9.
Step-by-step explanation:
Let x and y be the two unknown numbers.
Their sum is -5. Hence:
\(x+y=-5\)
Their difference is 13. Hence:
\(x-y=13\)
This yields a system of equations. We can solve this using elimination. Adding the two equations together:
\((x+y)+(x-y)=(-5)+(13)\)
Simplify:
\(2x=8\)
Divide both sides by two. Thus:
\(x=4\)
Using either equation (I'll use the first):
\((4)+y=-5\Rightarrow y=-9\)
So, our two numbers are 4 and -9.
The smaller number is -9.
