How to obtain the balance using simple interest?

The balance of an account after t years, using simple interest, that is, a single compounding per year, is given by the equation presented as follows:

A(t) = P(1 + rt).

In which the parameters of the equation are explained as follows:

P is the value of the initial deposit.r is the interest rate, as a decimal.

The parameter values for this problem are given as follows:

A = 17873.97, P = 17500, r = 0.065.

Hence the time in years is obtained as follows:

17873.97 = 17500(1 + 0.065t)

1 + 0.065t = 17873.97/17500

1 + 0.065t = 1.02136971429

t = (1.02136971429 - 1)/0.065

t = 0.32876483523

A year is composed by 365 days, hence the time in days is given as follows:

0.32876483523 x 365 = 120 days.

In 2015, the per capita consumption of bottled water in the United States was reported to be 36.2 gallons. Assume that the per capita consumption of bottled water in the U.S. is approximately normally-distributed with a standard deviation of 10 gallons.
Find the Z-score of someone who consumed 26.2 gallons of water. Using the Empirical Rule, what is the approximate probability that someone in the United States consumed less than 26.2 gallons of water, what is the approximate probability that someone in the United States consumed between 26.2 and 36.2 gallons of water, and what is the approximate probability that someone in the United States consumed between 26.2 and 46.2 gallons of water?

Answers

The required probabilities = 0.16

The required probabilities = 0.68

What is z-score?

The Z-score quantifies the discrepancy between a given value and the standard deviation. The Z-score, also known as the standard score, indicates how many standard deviations a specific data point deviates from the mean. In essence, standard deviation represents the degree of variability present in a particular data collection.

As given that,

μ = 36.2

σ = 10

As per empirical Rule:

μ± σ = 36.2 ±10 = 26.2, 46.2 = 68%

μ± 2σ = 36.2 ±20 = 16.2, 56.2 = 95%

μ ± 3σ = 36.2 ±30 = 6.2, 66.2 = 99.7%

less than 26.2:

13.5% + 2.35% + 0.15% = 0.16

between 26.2 and 36.2:

68% = 0.68

The dot product of a.b is 20.

What is the dot product?

The dot product (also called scalar product or inner product) of two vectors a and b in a Euclidean space is a scalar value that represents the projection of one vector onto the other and the cosine of the angle between them. The dot product of two vectors a and b is defined as:

a · b = ||a||||b||cos(θ) = a1b1 + a2b2 + ... + anbn

where a = (a1, a2, ..., an) and b = (b1, b2, ..., bn) are the components of the vectors and θ is the angle between the vectors.

Finding a · b:

Given a = (4, 1, 1) and b = (8, -3, -9), we can calculate the dot product as:

a · b = 4 * 8 + 1 * -3 + 1 * -9 = 32 - 3 - 9 = 20

The evaluation of obtuse angle ∠AOC is 124°.

What does "obtuse angle" mean?

Any angle more than 90 degrees is deemed obtuse: A straight angle is one with a 180° measurement: A zero angle is one with a measurement of 0°: Angles with measures that add up to 90 degrees are said to be complementary angles: Angles with measures that add up to 180° are referred to as supplementary angles.

3x + 94 + x + 30 + 2x - 4 = 180

Sum of angle in a triangle

6x + 120° = 180°

6x = 180° - 120°

6x = 60°

What is Probability ?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

A statistical function known as a probability distribution explains all the potential values and probabilities for a random variable within a certain range.

The uniform probability distribution is a distribution composed by two bounds, given by a and b, in which each possible outcome within these two bounds is equally as likely.

The probability that a call is made in the first quarter is 15/60

A molecular formula is a chemical formula that represents a molecule and gives information about the number and type of atoms present in the molecule. This formula is unique to each molecule and distinguishes one molecule from another, even if they have the same number and type of atoms arranged in a different way.

For example, the molecular formula for glucose (C6H12O6) is different from that of fructose (C6H12O6), even though they have the same number and type of atoms. The molecular formula represents the actual number of atoms present in the molecule and their chemical makeup, which in turn determines the chemical properties and behavior of the molecule.

The vertex of an angle in standard position on a coordinate plane is at the plane's origin. The angle's terminal side is rotated anticlockwise from the starting side while the angle's initial side is on the positive x-axis. The number of degrees the terminal side has travelled away from the initial side anticlockwise is how an angle is measured in standard position. This signifies that the terminal side is exactly on the same line as the initial side because the angle has the smallest positive measure of 0°.

Answers

The probability that the 5th ball drawn is red and the 8th ball drawn is blue is 45/196 or approximately 0.2307.

What is probability ?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.

The probability of drawing a red ball on the 5th draw is the number of red balls divided by the total number of balls in the bin, which is 5/14. The probability of drawing a blue ball on the 8th draw is the number of blue balls divided by the total number of balls in the bin, which is 9/14.

The probability of both events happening is the product of the individual probabilities:

P(red on 5th draw and blue on 8th draw) = (5/14) * (9/14) = 45/196

So, the probability that the 5th ball drawn is red and the 8th ball drawn is blue is 45/196 or approximately 0.2307.

Throughout this module, you have learned how to gather and present information to help justify your answer. You will use this skill, along with your knowledge of constructing figures in Geometry, to construct an argument in paragraph form.
Step 1: Tips on Formulating Your Argument
Here are some tips on formulating your argument:
● Think, Think, Think​. Ask yourself lots of questions about each side of the topic, then answer them based on your research findings, your opinion, and your experiences with both sides of the argument.
● Think from the other side.​ It is impossible to refute, or prove false, someone’s claim if you don’t know what he or she is thinking ahead of time.
● Create a list of some sort that helps you organize your thoughts.​ The more organized you are, the more prepared you will be and the more likely you are to win a debate!
● Cite your sources when you are speaking.​ Citing your sources gives your arguments more credibility. For example, you might say, "According to an article in the ​Math Rocks Journal​ ..."
● Use credible sources.​ Credible sources are ones readers can trust and ones that can be backed up with evidence. Not all sources carry the same weight; use sources that enhance your argument. Wikipedia is not a reliable or credible source.
● Use effective speech and grammar​. Remember, you are trying to get others to side with you, so speak clearly and professionally.
● Do more research. ​If you haven’t caught on by now, formulating your argument takes a lot of digging. Essentially, you have to prove your
points. You can even research how to debate! Take really good notes.
Step 2: The Argument
Here are the two arguments:
Argument A:​ There is a need for students to understand and be able to construct geometric figures using a compass and straightedge.
Argument B:​ There is no need for students to use a compass and straightedge, and ​all​ geometric constructions should be done using a drawing program.
There are two opposing arguments listed above. You need to choose which one you will support as your argument. Formulating an argument takes research and time to get yourself to the point where you can defend your position thoroughly.
Step 3: What to Submit
You may use any word processing program to present your argument, but you must include the following:
1. A summary of your argument.​ The summary should begin with the argument statement you chose. In addition, provide ​at least three
reasons ​why the method you chose is better than the other method ​and​ ​at ​least three reasons why the other method is not better​. This
summary can have a lot of opinion in it and should be persuasive and argumentative. You should submit in paragraph form.
2. A list of at least two resources used. ​Resources may include interviews with professionals and/or URLs of websites. Remember, you may
gather ideas from research, but you must explain the ideas yourself. Copying and pasting someone else's ideas is plagiarism. Be sure to avoid plagiarism by phrasing your argument in your own words. Reach out to your teacher if you have any questions.

Answers

An argument that supports Argument A is given below:

Geometric figures play a crucial role in many areas of mathematics and science, including engineering, architecture, physics, and computer graphics.

Why is it important to understand and be able to construct geometric figures?

Being able to construct these figures accurately and efficiently is therefore an important skill for students to have. By using only a compass and straightedge, students can explore and understand the properties of different shapes and their relationships with one another.

This helps them develop their spatial reasoning abilities and improves their understanding of mathematical concepts such as congruence, similarity, and symmetry.

Furthermore, this skill can be applied to solving real-world problems, such as determining the dimensions of a building or designing a circuit board.

In conclusion, the ability to construct geometric figures using a compass and straightedge is essential for students' mathematical and scientific development and should be taught as part of their education.

How to find the diagonal of a cuboid?

A cuboid is defined as a six-sided solid known as a hexahedron in geometry. Quadrilaterals make up its faces.

A diagonal in geometry is defined as a line segment that connects two polygonal vertices when they are not on the same edge.

The parameters are;

A, B, C, D, E, F, G & H form a cuboid. AB= 3.2 cm, BC = 1.6 cm & CG = 7.7 cm. That is l=3.2 cm, b=1.6 cm, h=7.7 cm.

A body diagonal is referred to as the diagonal of cuboid. The diagonal of cuboid formula is;

Diagonal length = √(l² + b² + h²) units.

Thus lugging in the relevant values;

Diagonal length = √(3.2² + 1.6² + 7.7²)

question content area top part 1 suppose a 4×7 coefficient matrix for a system has four pivot columns. is the system consistent? why or why not?

Answers

If a 4x7 coefficient matrix has four pivot columns, the system is consistent and has exactly one solution.

A coefficient matrix is a matrix that represents a system of linear equations. In the case of a 4x7 coefficient matrix, the matrix has 4 rows and 7 columns.

When it comes to determining the consistency of a system of linear equations, the presence of pivot columns is a key factor.

A pivot column is a column that contains a leading 1 in the row reduced echelon form of the matrix. If a system has four pivot columns, this means that the system has 4 linearly independent equations, meaning that there is exactly one solution to the system.

Therefore, the system is considered consistent.

However, if the number of pivot columns is less than the number of unknowns, then the system is considered inconsistent, meaning that there is either no solution or an infinite number of solutions.

Suppose that y(t) solves the ordinary differential equation
dy/dt = (4-3Y)/(5+2Y) Y(0)=0 Find d2y/dt2 (0)

Answers

To find the second derivative of y(t) at t = 0, we can use the chain rule. We can write the given equation as dy/dt = f(y), where f(y) = (4-3y)/(5+2y).

Then the second derivative of y at t = 0 can be calculated as: d2y/dt2 (0) = f'(y) * dy/dt (0) = f'(0)f(0) = [-3/(5+20)](4-30)/(5+2*0) = -3/5.

A differential equation is an equation that relates one or more unknown functions and their derivatives. It is mainly used in the fields of biology, physics, engineering, economics, and other sciences.

A differential equation states how a rate of change (a "differential") in one variable is related to other variables. For example, the Single Spring simulation involves a differential equation that describes the displacement of a spring in response to a force.

anderson and addison leave from the same restaurant and the same time, traveling in opposite directions. if anderson travels 15 mph and addison travels 6 mph, how long until they are 126 miles apart?

Answers

After 6 hours, Anderson and Addison will be 126 miles apart.

Let's call the time they have been traveling "t" (in hours).

Anderson will have traveled 15t miles and Addison will have traveled 6t miles. The total distance between them is 15t + 6t = 21t miles.

We know that they need to be 126 miles apart, so we can set up the equation:

21t = 126

Now we can solve for t:

t = 126 / 21

t = 6

So after 6 hours, they both will be 126 miles apart.

What is scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given that, a map of a national forest has a scale in which 1 inch represents 3 miles.

If two picnic areas in the national forest are actually located 15 miles apart, then on map it is 15/3 =5 inches

A function equation in slope-intercept form to model the situation are as follows;

Slope: 3.

Y-intercept: 48.

Equation: y = 3x + 48.

What is the slope-intercept form?

In Mathematics, the slope-intercept form of a line can be calculated by using this linear equation:

y = mx + c

Where:

x represents the number of minutes.y represents the temperature.m represents the slope of a line.c represents the y-intercept of a line.

Since the liquid started at a temperature of 48 degrees and drops 3 degrees per minute, an equation that model the situation is given by:

y = mx + c

y = 3x + 48

Next, we would fill in the table as follows. At x = 0, the temperature of liquid (y) is given by:

y = 3(0) + 48

y = 48.

At x = 1, the temperature of liquid (y) is given by:

y = 3(1) + 48

y = 51.

At x = 2, the temperature of liquid (y) is given by:

y = 3(2) + 48

y = 54.

At x = 3, the temperature of liquid (y) is given by:

y = 3(3) + 48

y = 57.

At x = 4, the temperature of liquid (y) is given by:

y = 3(4) + 48

y = 60.

At x = 5, the temperature of liquid (y) is given by:

y = 3(5) + 48

y = 63.

At x = 6, the temperature of liquid (y) is given by:

y = 3(6) + 48

y = 66.

At x = 7, the temperature of liquid (y) is given by:

y = 3(7) + 48

y = 69.

At x = 8, the temperature of liquid (y) is given by:

y = 3(8) + 48

y = 72.
