Mr. Mudd gives each of his children $2000 to invest as part of a friendly family competition. The competition will last 10 years. The rules of the competition are simple. Each child can split up his or her $2000 into as many separate investments as they please. The children are encouraged to do their research on types of investments. The initial investments made may not be changed at any point during the 10 years; no money may be added and no money may be moved. Whichever child has made the most money after 10 years will be awarded an additional $10,000.
The table shows the investment made by each of Mr. Mudd’s children, and what happened to their investment over the decade long friendly competition.

Marie is $10 000 richer
Step-by-step explanation:
Albert

A = P (1 + r/n )^nt
A = 1000(1 + 0.001)¹²⁰ = $1127.43
(b) $500 losing 2%
0.98 × 500 = $490
(c) $500 compounded continuously at 0.8%
A = Pe^rt
= 500e^0.008 * 10
= $541.64
(d) Balance
Total = 1127.43 + 490.00+ 541.64 = $2159.07
Marie
(a) 1500 at 1.4 % compounded quarterly
A = 1500(1 + 0.0035)⁴⁰ = $1724.99
(b) $500 gaining 4 %
1.04 × 500 = $520.00
(c) Balance
Total = 1724.99 + 520.00 = $2244.99
Hans
$2000 compounded continuously at 0.9 %
A = 2000e^0.009 * 10
= $ 2188.35
Max
(a) $1000 decreasing exponentially at 0.5 % annually
A = 1000(1 - 0.005)¹⁰= $951.11
(b) $1000 at 1.8 % compounded biannually
A = 1000(1 + 0.009)²⁰ = $1196.29
(c) Balance
Total = 951.11 + 1196.29 = $2147.40
Marie is $10,000 richer at the end of the competition.

Suppose S = {1, 2, 3}, with P({1}) = 1/2 and P({1, 2}) = 2/3. What must P({2}) be?
The value of P({2}) for the given Finite set is found as P({2}) = 1/6.
Explain the meaning of the term finite set?Sets with a bounded number of participants are referred to as finite sets. Due to their ability to be numbered, finite sets also are known as countable sets. If the members of the elements of all this set are finite, then the operation will run from out elements to list. Finite set illustrations include P = { 0, 3, 6, 9, …, 99}For the stated question;
S = {1, 2, 3},P({1}) = 1/2 and P({1, 2}) = 2/3.P({2}) will contain only element with is not present in set P({1}) counting from P({1, 2}).
Thus,
P({2}) = P({1, 2}) - P({1})
P({2}) = 2/3 - 1/2
P({2}) = 1/6
Thus, the value of P({2}) for the given Finite set is found as P({2}) = 1/6.

Hello,
I hope you and your family are doing well!
Let's call Sydney's age x and Devaughn's age y. We know that y = 3x and x + y = 116.
Substituting the first equation into the second equation gives:
3x + x = 116
4x = 116
x = 29

If a polynomial f(x) has a remainder of 4 when divided by x-5, what is f(5)?
The value of f(5) When a polynomial f(x) is divided by x -5 is 4
What is a polynomial?Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable.
If f(x) has a remainder of 4 when divided by x - 5
Then it means that if f(x -5) = f(0)
x -5 = 0
x = 5
so if you substitute 5 into f(x) which is f(5) it will give 4
so therefore f(5) = 4
In conclusion f(5) is same as 4

"a. What was the population of the state in 2000 ?
b. When will the population of the state reach 28.3 million?
a. In 2000 , the population of the state was million."
In 2000, the population of the state was 23.1 million, After 13 years , the population of the state reach 28.3 million.
What is population?
The term "population" refers to all citizens who are present in a nation or who are temporarily absent from it, as well as all aliens who have made a nation their permanent home. The number of residents in a given area is depicted by this indicator. The annual changes in population brought on by births, deaths, and net migration are measured as growth rates.
Given:
[tex]A = 23.1e^0^.^0^1^5^2^t[/tex] models the population of US
where A is in million
t is years after 2000.
(a) We have to find the population in 2000.
In 2000, t = 0
Plug t = 0 in the above equation
[tex]A(0) = 23.1e^0^.^0^1^5^2^(^0^)\\A = 23.1[/tex]
Hence, in 2000 the population is 23.1 million.
(b) To find when the population of the state reach 28.3 million.
Plug A = 28.3 in above equation and solve for t.
[tex]28.3 = 23.1e^0^.^0^1^5^2^t\\e^0.0152t = \frac{28.3}{23.1} \\t*ln(0.0152) = ln( \frac{28.3}{23.1})\\t = 13.35718\\t = 13[/tex]

What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
Suppose the amount of money spent be x.
And, the number of food items be y.
Now, as per the question the function can be written as follows,
y = x/182
As the number of food items can only be positive integers, the values of x must be the multiples of 182.
Thus, the expression for the domain can be written as x ≥ 182.

The appropriate estimate for the diameter of the speck of dust is 2 × 10⁻⁵ inches. So the answer is option A, 2 × 10⁻⁵ in.
What is Scientific Notation:In scientific notation, numbers are written with the base 10 much like in decimal notation. Scientific notation is the term used when a number is expressed as the product of two numbers.
Where the first number is more than or equal to one but less than ten and the second number is the power of ten expressed in exponential form.
Convert Decimal to Scientific Notation:Step - 1 Move the decimal point up to the first number that is equal to 1 but less than 10.
Step - 2 Count the number of places that the point moved.
Step - 3 Now Write the resultant number as a product with a power of 10.
Here we have
Diameter of a speck of duct = 0.00002 inches
Convert the given decimal into a scientific notation
As we learn above
Move the decimal point up to a whole number toward the right
=> 0.00002 = 2. = 2
Count the number of zeros or places moved
=> n = 5
Now write the number as a power of 10, Now write the above whole number part as the product of 10
=> 2 × 10⁻⁵ [ ∵ The power is moved right we need to use negative ]

The appropriate estimate for the diameter of the speck of dust is 2 × 10⁻⁵ inches. So the answer is option A, 2 × 10⁻⁵ in.

much will each donor owe? What is that distance?
Tucker's mother and grandmother will each owe $

if he walks
The distance for Tucker to walk is 1 mile, only then both the donors would have the same amount. This was found using linear equations.
What are linear equations?
A linear equation is one in which the variable's maximum power is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation. A linear equation with two variables has the formula Ax + By = C as its standard form. Here, the variables are x and y, the coefficients are A and B, and the constant is C.
Since it's given that Tucker's mother will give flat $5. So let that be the RHS of the equation. Now his grandmother will give him $5 for every mile he walks.
Let that be 5x.
Now the equation would be: 5x=5
Which results in x=1.

The confidence interval of this confidence level as calculate from the given data is 3.68 and 99% respectively.
Number of random sample (n)=28
Sample Standard deviation (S)=19.52
Confidence interval = 439.23 - 460.77 = 21.54

What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Calculate the perpendicular side for both triangles by using the Pythagorean theorem.
H² = P² + B²
Here, H is the hypotenuse, P is perpendicular and B is the base.
For the first triangle, the perpendicular is calculated as,
P² = x² - 10²......................................................1
For the second triangle, the perpendicular will be,
P² = ( 30² - x² ) - 20² .......................................2

The time needed for the account value to reach 11200 dollars is approximately 15.9 years.
What is the time required to reach the accrued amount?Simple interest formula is expressed as;
A = P( 1 + rt )
Where A is accrued amount, P is principal, r is interest rate and t is time.
Given the data in the question;
Accrued amount A = $11200 Principal P = $5400Interest I = 6.75%Time r = ?Plug the given values into the above formula and solve for time t.
A = P( 1 + rt )
A/P = 1 + rt
( A/P - 1 ) = rt
t = ( A/P - 1 ) / r
t = ( $11200/$5400 - 1 ) / 6.75%
t = ( $11200/$5400 - 1 ) / 6.75/100
t = ( 56/27 - 1 ) / 0.0675
t = ( 29/27 ) / 0.0675
