Dylan purchased a new car in 1993 for $26,300. The value of the car has been depreciating exponentially at a constant rate. If the value of the car was $2,700 in the year 2001, then what would be the predicted value of the car in the year 2006, to the nearest dollar?
Answers
The predicted value of the car in the year 2006 to the nearest dollar would be $651.
What is the predicted value of the car?The first step is to determine the rate of depreciation
g = (FV/PV)^(1/n) - 1
Where:
FV = value of the car in 2001
PV = value of the car in 1993
n = number ofyears = 8
(2700/26,300)^(1/8) - 1 = -24.76%
Now determine the value of the car in 2006
2700x ( 1 - 0.2476)^5 = $651

Sally buys 5 dolls and 1 purse for $21.
Donna buys 7 dolls and 1  purse for 27$
Answers
Answer:
1. The unit price for a doll is three dollars. The unit price for a purse is six dollars.
2. One doll costs three. One purse costs six.
3. Polly spends $24 on the 2 dolls and 3 purses.
Step-by-step explanation:
Doing some calculations, 1 doll costs three dollars and 1 purse costs six dollars.
5 x 3 + 6 = 21
7 x 3 + 1 = 27
If Polly buys 2 dolls and 3 purses, that means she spends six dollars on the dolls and eighteen dollars on the purses.

let x equal an integer selected at random from the first m positive integers, {1,2,...,m}. find the value of m for which e[x]
Answers
The expected value of x is (m+1)/2, and m must be a positive integer.
The expected value of x is the average value of x that we would expect to get if we selected an integer from the set {1, 2, ..., m} many times. To find the expected value of x, we multiply each possible value of x by its probability of being selected and then sum these products. In this case, each integer in the set {1, 2, ..., m} has an equal probability of being selected, so the expected value is (1 + 2 + ... + m) / m = (m(m+1)) / 2m = (m+1) / 2. So the expected value of x is (m+1)/2, and m must be a positive integer.

Which of the following statements with respect to political risk is true?
Oa. Political risk premiums are added to the required rate of return to adjust for political risks.
b. Companies cannot take any steps to reduce the potential from loss from expropriation since a foreign
government is involved.
Oc. The risk of expropriation of U.S. assets abroad is high even in traditionally friendly and stable countries.
Od. A company can reduce political risk by structuring operations so that the subsidiary has value only as a part of the
integrated corporate system.
Answers
This statement is true. Political risk is the risk of loss in an investment due to political instability or changes in government policy. Companies can adjust for the potential impact of political risk by adding a political risk premium to their required rate of return. This premium compensates investors for the additional risk associated with the investment due to political factors. The size of the premium will depend on the specific country, the nature of the investment, and the perceived level of political risk. Companies can also take steps to reduce political risk, such as diversifying their operations, investing in political risk insurance, or structuring operations to minimize the value of a subsidiary that might be subject to expropriation.

On a recent survey from Starbucks, 4200 people were asked their age. The mean age was found to be 28 years with a standard deviation of 18 months. Assume that the data is normally distributed and use the 68-95-99.7 Rule to answer the following questions. a) Of those surveyed, about how many people are at least 26.5 years old? people b) of those surveyed, about how many people are less than 26.5 years old? people
Answers
a) Approximately 84% of the people are at least 26.5 years old. So, about 3528 people (0.84 * 4200).
b) Approximately 16% of the people are less than 26.5 years old. So, about 672 people (0.16 * 4200).
How to solvea) 26.5 years is 1.5 years (18 months) less than the mean (28 years). This is 1 standard deviation (18 months) below the mean.
The 68-95-99.7 Rule states that 68% of the data falls within 1 standard deviation of the mean. So, 100% - 68% = 32% is outside 1 standard deviation.
Since it's symmetrical, one-half of that 32% (16%) is less than 26.5 years, and the other half (16%) is older than 29.5 years.
Consequently, 100% - 16% = 84% is over 26.5 years old. If you multiply 0.84 by 4200, you get 3528 people.
b) As calculated earlier, 16% of the people are less than 26.5 years old. 0.16 * 4200 = 672 people.

A first course in differential equations with modeling applications ninth edition is a textbook that covers the basics of differential equations and their applications in mathematical modeling.
It begins with an introduction to the concepts of differential equations, including the definition, solution methods, and the concept of modeling. It then covers topics such as first-order linear equations, higher-order linear equations, systems of linear differential equations, and nonlinear equations. It also has a chapter on boundary-value problems, which is a type of differential equation that involves a set of boundary conditions that must be satisfied for the solution to be valid.
In order to solve differential equations with boundary-value problems, we must first define the boundary conditions that must be satisfied for the solution to be valid. This involves setting up the boundary conditions in terms of the dependent and independent variables of the equation. We then solve the equation using the boundary conditions and the equation itself. The solution is then used to calculate values for the independent and dependent variables at the boundary points. Finally, we can verify the solution by substituting the calculated values into the equation and seeing if the solution is valid.

Question 2:
- Shakira paid $3 to rent shoes for bowling. At this point, she has spent a total of $3.
- Next, she plays bowling games each worth $4.75. This means that:
For her 1st game, she will pay $4.75
For her 2nd game, she will pay 2($4.75)
For her 3rd game, she will pay 3($4.75)
For her 4th game, she will pay 4($4.75)
And so on.
- We can see that her total cost paying for the games follows a pattern and we can therefore generalize. If Shakira plays n games, it means that:
For her nth game, she will pay n($4.75).
- Thus, the total amount that Shakira pays is the amount paid for the shoes plus the amount paid for the games.
- Thus, we can write the equation showing her total cost as follows:
\(\begin{gathered} \text{Total cost}=Amt\text{ paid for the shoes }+Amt\text{ paid for the games} \\ \text{Amt paid for the shoes}=3 \\ \text{Amt paid for the shoes}=4.75n \\ \\ \therefore\text{Total Cost}=4.75n+3 \\ \text{where, n is the number of games} \end{gathered}\)- Since Shakira spent a total of $42, we can find the number of games (n) that she played as follows:
\(\begin{gathered} 42=4.75n+3 \\ \text{Subtract 3 from both sides} \\ 42-3=4.75n \\ 4.75n=39 \\ \text{Divide both sides by 4.75} \\ \frac{4.75n}{4.75}=\frac{39}{4.75} \\ \\ \therefore n=8.21 \\ \text{ Since she cannot pay a decimal number of games, we should round the number down} \\ \\ \therefore n=8 \end{gathered}\)Question 3:
- In solving this question, we shall convert the information given to a mathematical equation
- Let the number of Field trips taken last year be f.
- Three times as many field trips as last year implies
\(3f\)- Two more than three times as many field trips as last year implies
\(2+3f\)- Cornell's class takes Two more than three times as many field trips as last year and this number of trips this year is 8.
Thus, we can say:
\(2+3f=8\)- This means we can find the number of field trips last year f by solving the above expression.
\(\begin{gathered} 2+3f=8 \\ \text{Subtract 2 from both sides} \\ 3f=8-2 \\ 3f=6 \\ \text{Divide both sides by 3} \\ \frac{3f}{3}=\frac{6}{3} \\ \\ \therefore f=2 \end{gathered}\)Final Answer
Question 2:
- The number of games is 8
- The equation is:
\(42=4.75n+3\)
Question 3:
- The number of field trips from last year is 2
- The equation is:
\(2+3f=8\)

A population mean is normally distributed with a mean of 56 and a standard deviation of 12.
Answers
The mean of the sampling distribution (p) and The standard error of the mean (o) are 56 and 2 respectively.
What is normal distribution?A probability distribution that is symmetric about the mean is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean.
According to question:(a) The mean of the sampling distribution (p) is equal to the population mean, which is 56.
(b) The standard error of the mean (o) is calculated as the standard deviation of the population divided by the square root of the sample size. So for a sample of 36 participants:
o = 12 / √36 = 2
(c) The distribution of the sample means (p) will be approximately normal with a mean of 56 and a standard deviation of 2. To sketch this distribution with M ± 3 SEM, we would plot a normal distribution with mean 56 and standard deviation 2, and shade the region that is 3 standard errors away from the mean on either side.
This region would capture approximately 99.7% of the data if the samples were selected randomly and independently from the population.

What is the best approximation of the area of a circle with a diameter of 17 meters?
Use 3.14 to approximate pi.
Answers
the best approximation of the area of the circle with a diameter of 17 meters is approximately 226.99m².
Why it is and what is diameter?
The diameter of the circle is 17 meters, which means the radius is half of the diameter, or 8.5 meters.
The formula for the area of a circle is:
A = πr²2
where A is the area and r is the radius.
Substituting the value of the radius into the formula, we get:
A = 3.14 x 8.5²2
A = 3.14 x 72.25
A ≈ 226.99
Therefore, the best approximation of the area of the circle with a diameter of 17 meters is approximately 226.99 m².
In geometry, the diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circle. It is the longest chord (a line segment connecting any two points on a circle) of the circle, and it divides the circle into two equal halves, also known as hemispheres.
