Answer 1

The period of the solar system's orbit is 2.05 x 108 years.

What is the time period?

A period is a number that in algebraic geometry can be expressed as the integral of an algebraic function over an algebraic domain. Periods form a ring because their sums and products always remain in the same period.

Don Zagier and Maxim Kontsevich presented some theories and gave a survey of the eras. Periods also appear when computing the integrals that result from Feynman diagrams, and extensive work has been done to understand the relationships.

Solution Explained:

Given,

Radius of the solar system, r=25000 light year

Speed v=230 km/s

Calculate time period by

T = 2πr / v

T = 2πr X (25000 X 3 X 10^8 X 365 X 24 X 60 X 6) / (230 X 10^3)

  = 6.46 X 10^15 X (1 year / 365 X 24 X 60 X 60)
  = 2.05 X 10^8 years

What is Exponential function?

A mathematical function with the form f (x) = ae^x is an exponential function. "x" is a variable, and "a" is a constant that serves as the function's base and must be greater than 0. The transcendental number e, or roughly 2.71828, is the base for exponential functions that is most frequently used.

Growth rate = 100% in 17 years

  In 1 year = 5.88% growth

Initial population = P₀ = 1725

Time = 17 years

So, after 10 years population

        P= P₀ ( 1 + [tex]\frac{r}{100}[/tex])^t

           = 1725 ( 1 + 5.88/100 )^10

           =≈ 1725 * 1.77

           =≈ 3054

Hence, the population growth after 10 years at the rate of 5.88 % would be 3054.

Answers

The values of the functions defined in the piecewise function are f(0) = 5 and f(-4) = 11

How to evaluate the piecewise function?

From the question, we have the following piecewise function that can be used in our computation:

f(x) = | x + 5                 x < -2

         x² + 2x + 3        x ≥ -2

Evaluating the function f(0)

In this function, we have the x value to be

x = 0

This x value is at the domain x < -2

So, we make use of

f(x) = x + 5

Substitute 0 for x in f(x) = x + 5

f(0) = 0 + 5

Evaluate

f(0) = 5

Evaluating the function f(-4)

In this function, we have the x value to be

x = -4

This x value is at the domain x ≥ -2

So, we make use of

f(x) = x² + 2x + 3

Substitute -4 for x in f(x) = x² + 2x + 3

f(-4) = (-4)² + 2(-4) + 3

Evaluate

f(-4) = 11

Hence, the value of f(-4) is 11

Answers

The distance between two points (4, 0) and (2, -9) is √85 units in the simplest radical form.

What is meant by distance between two points?

The length of the line segment connecting two points in a plane is defined as the distance between them. The formula for calculating the distance between two points is commonly presented as √(x₂-x₁)²+(y₂-y₁)².

Distances in geometry are usually positive, unless when the points coincide. We consider two points A(a, b) and B to obtain the formula for the distance between two points in the plane (c, d).

The given two points are (4, 0), (2, -9).

Distance between two points is given by,

Distance=√(x₂-x₁)²+(y₂-y₁)²

Where x₁, x₂, y₁, y₂ are the points.

So, the distance between (4, 0) and (2, -9)

=√(2-4)²+(-9-0)²

=√4+81

=√85 units

Therefore, the distance between two points (4, 0) and (2, -9) is √85 units in the simplest radical form.

Answers

Answer:

28.9641 ≤ x-bar(t) ≤ 39.0359.

Step-by-step explanation:

1. Determine the size of the sample (n).

Knowing that we have 10 different values of speed, the size of the sample is 10; n=10. Therefore, this sample is considered statistically small because n < 30.

2. Calculate the arithmetic mean of the sample.

Arithmetic mean= (Sum of all values) / (Amount of values)

x-bar= (340) / (10)

x-bar= 34.0000.

x-bar= arithmetic mean.

3. Calculate the standard deviation using the formula for samples.

We're going to use the Microsoft Excel tool for the standard deviation for samples (check attached image 1).

Standard deviation for samples (s)= 7.0396.

4. Calculate σ(x-bar).

Check attached image 2.

σ(x-bar)= 2.2261.

5. Calculate α/2.

α is the error that the confidence interval will have. Given a 95% confidence level, we know that the error is 5%; Error= 1 - Confidence.

α/2= 5%/2= 0.05/2= 0.025.

6. Find the absolute t-student value for α/2.

You can either use the probability tables or the Microsoft Excel tools to find the inverse of a t-student distribution for this α/2 value (check attached image 3).

In this case we use the t-student distribution instead of the normal distribution because the sample size is small and the standard deviation of the population is unknown.

T-student value= -2.2622

Absolute t value= 2.2622.

7. Calculate the intervals.

Check attached image 4 to see the formulas.

Lower limit = (34) - (2.2622*2.2261) = 28.9641

Upper limit = (34) + (2.2622*2.2261) = 39.0359

28.9641 ≤ x-bar(t) ≤ 39.0359

8. Conclude.

This result means that the value of speed could be any value between 28.9641 and 39.0359, including, with a 95% confidence level. There's a 5% chance that a newly measured value of speed is outside this interval.

Answers

The probability that you will catch a t-shirt that is not of medium size would be 0.7

What is the probability?

Probability is a branch of mathematics that deals with numerical descriptions of how likely an event is to occur or how likely a proposition is to be true. The probability of an event is a number between 0 and 1, where 0 indicates the event's impossibility and 1 indicates certainty.

Small=S=20, M=medium=30,

L = Either large or extra large=50

P(T-shirt that is not a medium)= 1 - P(T-shirt is medium)

                                           = 1 - 30/100

                                           = 1 - 0.3

Answers

A car travels 500/3 meters in 2 seconds.

What is speed?

The speed at which an object's location changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Given that it just has a direction and no magnitude, speed is a scalar number.

Here, we have

Speed of car  = 100 KM/ hour

1 km= 1000m

1 hour = 3600 seconds

Let's find the speed of the car in Meters/second

Speed of car in m/sec = 100*1000 m/3600 second

Here we have taken 1000 for km and 3600 for an hour

Speed of car in m/sec = 100*1000 m/3600 second = 500/18 m/second

Speed of car in m/sec = 250/9  m per sec

We know that

Distance = speed*time

Speed = 250/9  m per sec

Time = 2 second

Distance = 250/9 * 2 meters = 500/3 meters

Line of best fit refers to the "a line through a scatter plot of data points that best expresses relationship between those points". Lines of best fit is used to describe data and predict data where the new data will appear. Examples for lines of best fit is 'Least square method'.

Two variables are said to be correlated or to have a correlation coefficient when "changes in the value of one variable produce changes in the variable of the other variable."

In order to find the correlation between two variables on a graph, the question asks for the line of best fit and correlation coefficient.

Only when there is a linear correlation between the variables—that is, when the relationship between the variables is linear on a graph—does the correlation coefficient hold true.

Variation in "x" on the graph leads to variation in "y." Variation in "y" on the graph results in variation in "x." The variables "x" and "y" are jointly dependent on the graph.

The correlation coefficient between two variables on the graph is calculated in this manner.

Hence, using line of best fit and correlation coefficient, the correlation coefficient of determination represent the percentage of data that is closest to the lines of best fit.

An equation to represent this situation is 16x - 5 = 14x + 1. The value of x is equal to 3.

The perimeters of the rectangle and triangle are equal to 43 units.

How to calculate the perimeter of a rectangle?

Mathematically, the perimeter of a rectangle can be calculated by using this equation;

P = 2(L + W)

Where:

P represents the perimeter of a rectangle.L represents the length of a rectangle.W represents the width of a rectangle.

An equation for the perimeter of this rectangle is given by:

P = 2[(5x - 2) + (3x - 0.5)]

P = 2(8x - 2.5)

P = 16x - 5.

Mathematically, the perimeter of a triangle can be calculated by using this equation:

P = a + b + c

Where:

P is the perimeter of a triangle.a, b, and c are the side length of a triangle.

P = (2x + 3) + (2x + 3) + (10x - 5)

given the length of a human's femur, x, and the length of a human's humerus, y, would you expect a positive correlation, a negative correlation, or no correlation?

Answers

The length of a human's femur, x, and the length of a human's humerus, Y would ,positive correlation.

A statistical measure known as correlation expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a typical technique for describing straightforward connections without explicitly stating cause and consequence.

A scale from + 1 to -1 is used to calculate the correlation coefficient. Either + 1 or -1 represents a variable's complete connection with another. The correlation is positive when one variable rises as the other rises; it is negative when one variable falls as the other rises.
