The total percentage increase in the investor's stock account is 0.17%.

Total percentage increase in

Let us total the amount in the stock account

Company A was worth $2500.

Company B was worth $3600.

Total = $5180

when the stock in Company A increased by 23%  she will have

$2500 *0.23=  $575

Company A will worth $3075

when The stock in Company B increased by 14%  she will have

$3600 *0.14=  $514

Company B will worth  $3086

In all after the decline in are portfolio is $3075+$3086= $6161

The difference for the original amount in her investment is = $3086-$3075 = $11

The total percentage decrease in the investor's stock account

= (11/6161)*100 = 0.147*100 = 0.17%

Answer:

  (-3, 4)

Step-by-step explanation:

The midpoints of the diagonals of a parallelogram are coincident. This means the sums of coordinates at the ends of the diagonals are the same. For missing point P, we must have ...

  P +(0, -3) = (-6, -6) +(3, 7)

  P = (-6, -6) +(3, 7) -(0, -3)

  P = (-6 +3 -0, -6 +7 -(-3))

  P = (-3, 4)

The values of x that make the inequality 16 < 4x + 8 true are all numbers greater than 2.

To solve the inequality 16 < 4x + 8, we need to isolate the variable x on one side of the inequality sign.
First, we subtract 8 from both sides to get 16 - 8 < 4x, which simplifies to 8 < 4x.
Next, we divide both sides by 4 to get 8/4 < x, which simplifies to 2 < x.
Therefore, the values of x that make the inequality true are any numbers greater than 2.
It's important to note that inequalities represent a range of values rather than a single solution. In this case, any value of x that is greater than 2 will satisfy the inequality.
Inequality statements like this are often used to describe real-world situations where there are limitations or restrictions. For example, if a store has a sale where all items are at least 30% off, we could write an inequality statement like "0.7p < s", where p is the original price of an item and s is the sale price. This means that the sale price must be at least 70% of the original price. Understanding and solving inequalities is an important tool for understanding and addressing social and economic inequalities in our world.

Answer: a)

Step-by-step explanation:

To find \(\frac{dy}{dx}\), we will have to use implicit differentiation, and because the base is \(dx\), we will take the deriviative of both sides with respect to \(x\).

To derive \(y\) with respect to \(x\), just derive the term with respect to y then multiply the term with \(\frac{dy}{dx}\).

So \(\frac{d}{dx} x^{2}\) is just \(2x\), \(\frac{d}{dx} y^{2}\) is \(2y \frac{dy}{dx}\), and  \(\frac{d}{dx} 289\) is 0. Now substitue each term with it's deriviative.

\(2x + 2y \frac{dy}{dx} = 0\)

Now, just solve for  \(\frac{dy}{dx}\) when \(x\) is 8 and \(y\) is 15

\(2(8) + 2(15)\frac{dy}{dx} = 0\)

\(16 + 30\frac{dy}{dx} = 0\)

\(\frac{dy}{dx} = \frac{-16}{30} = \frac{-8}{15}\)

So the answer is choice a)

Answer:

The balance on the loan f(p) = $100 - $20 × p

Step-by-step explanation:

The parameters of the question are;

The loan amount = $100

The amount of monthly payment for the loan = $20

The function rule for the balance of the function f(p) where p is the number of payments is given as follows;

The balance on the loan, f(p) = The loan amount less the total amount paid

The total amount payment Jeania has made = Amount of monthly payment × Number of months paid, p

The total amount payment Jeania has made = $20 × p

∴ The balance on the loan, f(p) = $100 - $20 × p

Which gives;

f(p) = $100 - $20 × p.

The differential equation is ndx/dt = kx, and to find the value of k such that x(t) = 9^t is a solution, substitute x(t) = 9^t into the equation and solve for k. The result is k = n * ln(9).

To determine the value of k such that x(t) = 9^t satisfies the given differential equation ndx/dt = kx, we can substitute x(t) = 9^t into the equation.

First, we need to find the derivative of x(t) using the chain rule. Therefore, nd(9^t)/dt = n * 9^t * ln(9). Then, we substitute nd/dt with n * 9^t * ln(9) in the differential equation.

This gives 9^t * n * 9^t * ln(9) = k * 9^t. We can simplify this to k = n * ln(9) by canceling out the 9^t term on both sides. Therefore, the value of k such that x(t) = 9^t satisfies the given differential equation is k = n * ln(9).

The mean of the deviation scores in any data distribution is also known by research scientists as the mean deviation or the average deviation. It is a measure of the average distance of each data point from the mean of the distribution.

The mean deviation is calculated by finding the absolute difference between each data point and the mean, adding up these differences, and dividing by the number of data points. Unlike the standard deviation, the mean deviation gives equal weight to each data point and is less affected by outliers.

However, it is not as commonly used as the standard deviation because it does not have the same statistical properties and is not as easily interpreted in terms of probability distributions.

The inner product of two vectors A = (2, -3,0) and B = (-1,0,5) is -2 / √(13×26).

Solving the given system of equations using Gaussian elimination:

2x + 3y + z = 2 y + 5z = 20 -x+2y+3z = 13

Matrix form of the system is

[A] = [B] 2 3 1 | 2 0 5 | 20 -1 2 3 | 13

Divide row 1 by 2 and replace row 1 by the new row 1: 1 3/2 1/2 | 1

Divide row 2 by 5 and replace row 2 by the new row 2: 0 1 1 | 4

Divide row 3 by -1 and replace row 3 by the new row 3: 0 0 1 | 5

Back substitution, replace z = 5 into second equation to solve for y, y + 5(5) = 20 y = -5

Back substitution, replace z = 5 and y = -5 into the first equation to solve for x, 2x + 3(-5) + 5 = 2 2x - 15 + 5 = 2 2x = 12 x = 6

The solution is (x,y,z) = (6,-5,5)

Therefore, the solution to the given system of equations using Gaussian elimination is (x,y,z) = (6,-5,5).

The given two vectors are A = (2, -3,0) and B = = (-1,0,5). The inner product of two vectors A and B is given by

A·B = |A||B|cosθ

Given,A = (2, -3,0) and B = (-1,0,5)

If the scores on an exam follow an approximately normal distribution with a mean of 76.4 and a standard deviation of 6.1 points, then the minimum score needed to be in the top 7% is calculated to be 85.404.

This type of normal distribution problem can be solved by using the z-score.

Considering Z to be the standard score, μ to be the mean, and σ to be the standard deviation, the z-score formula to find the minimum score to be in the top 7% can be given as,

Z = x - μ / σ

z-score can be determined using a standard table if the p-value is known.

As the minimum score to be in the top 7% is required to be found, p-value = 0.07

In the standard table, the z-score corresponding to the p-value of 0.07 is found to be 1.476

Therefore,

1.476 = x - 76.4 / 6.1

1.476 (6.1) = x - 76.4

9.004 = x - 76.4

x = 9.004 + 76.4

x = 85.404

Hence, the minimum score required to be in the top 7% is equal to 85.404
