How much should be invested at 7% compounded daily for 15 years to make $200,000?

Answer:

20 miles.

Explanation:

2x + 20 = 3x

x = miles driven

The left side of the equation represents Laguna's, and the right side Salvatori's.

You can multiply the miles driven by their price per mile. This gives you (2x) on the left, for Laguna's $2 per mile, and (3x) for Salvatori's $3 per mile.

The (+20) represents the initial payment for Laguna's, but Salvatori's doesn't have this, so we can leave it out.

Finally, eliminate.

Subtract 2x from 3x on the right. This leaves you with 20 = 1x.

Therefore, the volume of the paper cone to the nearest tenth is 418.7 inches cubed.

The volume of the paper cone that Gretchen made to hold a gift for a friend is given by;V= (1/3)πr²hWhere;r = radius of the paper coneh = height of the paper coneπ = 3.14

Given that;Height of the paper cone (h) = 16 inches Radius of the paper cone (r) = 5 inchesWe are to find the volume (V) of the paper cone to the nearest tenth of an inch.

To obtain the volume of the paper cone, we can substitute the values of r and h in the formula above to obtain;

\(V= (1/3)\pir^2hV\)= \((\frac{1}{3} ) \times 3.14\times5^2 \times16V = (\frac{1}{3} ) \times 3.14\times25\times16V = (\frac{1}{3}) \times 1256V=418.7\)

To calculate Nathan's net worth, we need to determine his total liabilities (debt) and subtract that from his total assets. The debt ratio tells us that Nathan's liabilities are 80% of his total net worth.

Total liabilities = Car loan + Mortgage + Student loans = $2,000 + $150,000 + $15,000 = $167,000

Nathan's net worth = Total assets = Total liabilities / Debt ratio = $167,000 / 0.8 = $208,750

So, Nathan's net worth is $208,750.

To show that the closure of a relation R with respect to a property P, if it exists, is the intersection of all relations with property P that contain R, we need to prove two things:

1. The closure of R with respect to P is a subset of every relation with property P that contains R.

2. The intersection of all relations with property P that contain R is a subset of the closure of R with respect to P.

Let's proceed with the proof:

1. The closure of R with respect to P is a subset of every relation with property P that contains R:

Assume that C is the closure of R with respect to P, and let's consider any relation S that contains R and has property P. We need to show that C ⊆ S.

Since C is the closure of R with respect to P, it means that C satisfies property P, and C contains R. Since S is a relation that contains R and has property P, it also satisfies property P and contains R.

Now, if x and y are two elements in C, then there exists a sequence of elements (x₁, x₂, ..., xₙ) such that x = x₁, y = xₙ, and (xi, xi+1) ∈ R for each i = 1 to n-1. Since R is a subset of S, (xi, xi+1) ∈ S for each i = 1 to n-1.

Therefore, we can conclude that (x, y) ∈ S, which means C ⊆ S. This holds for any relation S that contains R and has property P.

2. The intersection of all relations with property P that contain R is a subset of the closure of R with respect to P:

Assume that I is the intersection of all relations with property P that contain R. We need to show that I ⊆ C, where C is the closure of R with respect to P.

Since I is the intersection of all relations with property P that contain R, it means that I satisfies property P, and I contains R.

Now, let's consider any pair (x, y) ∈ I. By definition of intersection, (x, y) ∈ S for every relation S with property P that contains R. Therefore, (x, y) ∈ C as well since C is the closure of R with respect to P, and C contains R.

Hence, we can conclude that I ⊆ C.

Combining both proofs, we have shown that the closure of R with respect to P is the intersection of all relations with property P that contain R.

They are shown together to find units of 4 total

4 (j/ total + s/total )

= 4 (1/4 + 3/4)

=  4/4 + 12/4

= 4 cups total

Then show letters and work out for j + s

4(j/3 + 3/4) = 4

4j/3 + 12/4 = 4

4j/3 + 3 = 4

4j/3 = 4-3

4j/3= 1

j = 1/3     s = 3/4 * 4 = 3  

You would rearrange 4 within the brackets to find total

3 (1/3 + 4t) = 4

   1 + 12t = 4

         12t = 4-1

         12t = 3

             t = 12/3 of the total

            t = 4

False. The expected cell frequency in statistical analysis, specifically in the context of contingency tables and chi-square tests, is not based on the researcher's opinion. Instead, it is determined through mathematical calculations and statistical assumptions.

In contingency tables, the expected cell frequency refers to the expected number of observations that would fall into a particular cell if the null hypothesis of independence is true (i.e., if there is no relationship between the variables being studied). The expected cell frequency is calculated based on the marginal totals (row totals and column totals) and the overall sample size.

The expected cell frequency is computed using statistical formulas and is not influenced by the researcher's opinion or subjective judgment. It is a crucial component in determining whether the observed frequencies in the cells significantly deviate from what would be expected under the null hypothesis.

By comparing the observed cell frequencies with the expected cell frequencies, statistical tests like the chi-square test can assess the association or independence between categorical variables in a data set.

Thus, the statement "the expected cell frequency is based on the researcher's opinion" is false. The expected cell frequency is derived through statistical calculations and is not subject to the researcher's subjective input.

The sampling distribution of the difference in the sample mean length of candles between Machine 1 and Machine 2 is approximately normally distributed with a mean of 0 and a standard deviation of 0.0212 centimeters.

When we take a random sample of 49 candles from each machine, the sampling distribution of the difference in the sample mean length of candles follows a normal distribution. The shape of this distribution is symmetric and bell-shaped.

This means that the majority of the differences in sample means will be close to zero, representing little to no difference between the machines. The center of the sampling distribution is at 0, indicating that, on average, there is no difference in the sample mean length between the two machines.

The variability of the sampling distribution is represented by the standard deviation, which is calculated using the formula for the standard error of the difference in sample means. In this case, the standard deviation is 0.0212 centimeters, which indicates the average amount of variation or spread in the differences of sample means.

It's important to note that the shape, center, and variability of the sampling distribution are based on the assumptions of random sampling and independence of the samples from each machine.

The real solutions of the polynomial equation x⁴ = 16 are x = ±2.To find the real or imaginary solutions of the polynomial equation x⁴ = 16, we can start by rewriting it as x⁴ - 16 = 0.

We can then factor the equation as a difference of squares: (x²)² - 4² = 0. Now, we have a quadratic equation in the form a² - b² = 0, which can be factored using the difference of squares formula: (x² - 4)(x² + 4) = 0. From this equation, we get two possible cases: Case 1: x² - 4 = 0. Solving for x, we have: x² = 4; x = ±2. Case 2: x² + 4 = 0.  

This equation has no real solutions because the square of a real number is always positive. Therefore, the real solutions of the polynomial equation x⁴ = 16 are x = ±2.

The function represents exponential decay with a percentage rate of decrease of 9.8%.

The given exponential function y = 660(0.902) represents decay because the base of the exponent is less than one.

This means that the output value of the function will decrease as the input value increases.

To determine the percentage rate of decrease, we need to find the value of the base of the exponent subtracted from one and then multiply it by 100.

The base of the exponent is 0.902, so we subtract it from one to get 0.098.

Multiplying by 100 gives us a percentage rate of decrease of 9.8%.

This means that for every unit increase in the input value, the output value of the function will decrease by approximately 9.8%.

For example, if the input value increases from 1 to 2, the output value will decrease by 9.8%, and if the input value increases from 2 to 3, the output value will again decrease by 9.8%.

The vertex of your parabola lies at those two coordinates .The axis of symmetry, x is 1, was already discovered.

To locate a parabola's vertex, you must first determine x (or y, if your parabola is sideways) using the axis of symmetry formula. The quadratic equation will then be used to solve for y (or x, if your parabola opens to the side) using that value. The vertex of your parabola lies at those two coordinates.

The axis of symmetry is shown as a line, hence x=1. Since it is the highest or lowest point of the parabola, the vertex of a quadratic equation also serves as its maximum and minimum. We need to do a few things in order to locate the vertex: The axis of symmetry, x=1, was already discovered.
