Same age

See explanation below

Let the age of Jasmine = y

Multiplying Jasmine age by 3 and adding 6:

= (y × 3) + 6

= 3y + 6

Multiplyng the sum by 2:

2 × the sum = 2 × (3y + 6)

= 6y + 12

Let James age = z

Multiplying the age by 2 and adding 4:

James age × 2 = z × 2 = 2z

adding 4 = 2z + 4

Multiplying the sum y 3:

3 × the sum = 3 × (2z + 4)

= 6z + 12

Now since they are twins, they ae most likely same age

This means:

6y + 12 = 6z + 12

subtracting 12 from both sides:

6y = 6z

dividing both sides by 6:

y = z

Hence, Jasmine age is the same as James age

B) The expression for Jasmine = 2(3y + 6) = 6y + 12

The expression for James = 3(2z + 4) = 6z + 12

let the twin's age = 2, 3, 4, 5

when twin's age = 2

6y + 12 = 6(2) + 12 = 12 + 12 = 24

6z + 12 = 6(2) + 12 = 12 + 12 = 24

when twin's age = 3

6y + 12 = 6(3) + 12 = 18 + 12 = 30

6z + 12 = 6(3) + 12 = 18 + 12 = 30

when twin's age = 4

6y + 12 = 6(4) + 12 = 24 + 12 = 36

6z + 12 = 6(4) + 12 = 24 + 12 = 36

when twin's age = 5

6y + 12 = 6(5) + 12 = 30 + 12 = 42

6z + 12 = 6(5) + 12 = 30 + 12 = 42

Step-by-step explanation:

MATLAB program that finds the coefficients \(a\), \(b\), and \(c\) for the quadratic equation \(y = ax^2 + bx + c\) that passes through the given points:

```matlab

% Given points

x = [1, 4, 5];

y = [4, 73, 120];

% Formulating the system of equations

A = [x(1)^2, x(1), 1; x(2)^2, x(2), 1; x(3)^2, x(3), 1];

B = y';

% Solving the system of equations

coefficients = linsolve(A, B);

% Extracting the coefficients

a = coefficients(1);

b = coefficients(2);

c = coefficients(3);

% Displaying the coefficients

fprintf('The coefficients are:\n');

fprintf('a = %.2f\n', a);

fprintf('b = %.2f\n', b);

fprintf('c = %.2f\n', c);

% Plotting the equation

x_plot = linspace(0, 6, 100);

y_plot = a * x_plot.^2 + b * x_plot + c;

figure;

plot(x, y, 'o', 'MarkerSize', 8, 'LineWidth', 2);

hold on;

plot(x_plot, y_plot, 'LineWidth', 2);

grid on;

legend('Given Points', 'Quadratic Equation');

xlabel('x');

ylabel('y');

title('Quadratic Equation Fitting');

```

When you run this MATLAB program, it will compute the coefficients \(a\), \(b\), and \(c\) using the given points and then display them. It will also generate a plot showing the given points and the quadratic equation curve that fits them.

Note that the `linsolve` function is used to solve the system of linear equations, and the `plot` function is used to create the plot of the points and the equation curve.

Given

y = f(g(x)) , then

\(\frac{dy}{dx}\) = f'(g(x)) × g'(x)

\(\frac{d}{dx}\) (sinx) = cosx , \(\frac{d}{dx}\) (cosx) = - sinx

The covariance for the new data will be 1.4641 times the original covariance.

Let X and Y be two variables with a covariance cov(X, Y).

We can consider the data set S = {(x1, y1), (x2, y2), ..., (xn, yn)},

where xi and yi are the i-th values of X and Y.

Also,

let S' = {(1.21x1, 1.21y1), (1.21x2, 1.21y2), ..., (1.21xn, 1.21yn)} be the data set obtained by multiplying each value in S by 1.21.

To find the covariance of S', we use the formula cov(aX, bY) = ab cov(X, Y) for constants a and b.

Here, we have a = b = 1.21,

so we can write:

cov(S') = cov(1.21X, 1.21Y)

= 1.21 * 1.21 * cov(X, Y)

= 1.4641 * cov(X, Y)

Therefore, the covariance for the new data will be 1.4641 times the original covariance.

This is because covariance is a measure of the linear relationship between two variables, and scaling one or both variables by a constant multiplies the covariance by the square of that constant, as shown by the formula above.

Answer:

x²¹ /64

Step-by-step explanation:

To know the mistake made by Javier, let us simplify the given expression. This can be obtained as follow:

(20x / 5x⁸)¯³ = (20x)¯³ / (5x⁸)¯³

= (5x⁸)³ / (20x)³

= 5³x²⁴ / 20³x³

= 125x²⁴ /8000x³

= 125x²⁴ ÷ 8000x³

Recall

Mᵃ ÷ Mᵇ = Mᵃ¯ᵇ

Therefore,

125x²⁴ ÷ 8000x³ = (125/8000)x²⁴¯³

= (1/64) x²¹ = x²¹/64

Thus,

(20x / 5x⁸)¯³ = x²¹/64

The number of ways in which Kristen can rank her favorite four from 8 using permutations is 1680.

The permutation is a way of finding the number of ways of selecting a set of articles from a larger set of articles, with the order of selection being significant.

If we want to choose r items from n items, where the order of selection is significant, then we can find the number of ways of doing this using the permutation as follows:

nPr = n!/{(n - r)!}.

In the question, we are asked to find the number of ways Kristen can rank her favorite four investments from the 8 potential investments that her financial advisor has given her.

Thus, using permutations, we need to select 4 items from 8 items, with order of selection being significant.

Substituting n = 8, and r = 4 in the formula, we get:

8P4 = 8!/{(8 - 4)!}

= 8!/4!

= 5 * 6 * 7 * 8

= 1680.

Thus, the number of ways in which Kristen can rank her favorite four from 8 using permutations is 1680.

The probability that a random point on the line segment AK will be on the line segment CD is 0.6 or 60%.

To calculate the probability that a random point on the line segment AK will be on the line segment CD, we need to compare the lengths of the line segments CD and AK.

Let's start by finding the length of line segment AK. We can see that AK spans from point A to point K, which covers 5 units on the x-axis.

Next, let's find the length of line segment CD. We can see that CD spans from point C to point D, which covers 3 units on the x-axis.

Since the length of line segment AK is 5 units and the length of line segment CD is 3 units, the probability that a random point on AK will be on CD is given by the ratio of the lengths:

P = (Length of CD) / (Length of AK) = 3 / 5 = 0.6

Therefore, the probability that a random point on the line segment AK will be on the line segment CD is 0.6 or 60%.

Answer:

  x = 9

Step-by-step explanation:

You want the value of x that satisfies 6/40 = x/60.

This equation can be solved in one step: multiply by the inverse of the coefficient of x.

The coefficient of x is 1/60. Its inverse is 60/1 = 60. Multiplying the equation by 60 gives ...

  60(6/40) = 60(x/60)

  360/40 = x

  9 = x

__

Additional comment

Often, you will be advised to "cross multiply" as the first step in solving a proportion. Doing this would give you ...

  6(60) = 40(x)

Now, you would need to divide by the coefficient of x (or multiply by its inverse).

  6(60)/40 = (40x)/40

  360/40 = x = 9

This accomplishes in two steps what we did above in one step.

Step-by-step explanation:

1st you have to add up the total cost so:

213.15 + 344.21 + 76.65 = $ 634.01

next find 10% of 634.01

10% of 634.01 is 63.401

then you subtract 63.401 from 634.01 so basically you subtract the 10% discount from the total cost so:

634.01 - 63.401 = 570.609 is equal to $576.90

$576.90 is closest to $571
