Lucy has $7 less than Kristine and $5 more than Nina together, the three have $35. Lucy has $11.

Let's denote the amount of money that Kristine has as K, the amount of money that Lucy has as L, and the amount of money that Nina has as N.

According to the given information, we can form two equations:

Lucy has $7 less than Kristine: L = K - 7

Lucy has $5 more than Nina: L = N + 5

We also know that the three of them have a total of $35: K + L + N = 35

We can solve this system of equations to find the values of K, L, and N.

Substituting equation 1 into equation 3, we get:

K + (K - 7) + N = 35

2K - 7 + N = 35

Substituting equation 2 into the above equation, we get:

2K - 7 + (L - 5) = 35

2K + L - 12 = 35

Since Lucy has $7 less than Kristine (equation 1), we can substitute K - 7 for L in the above equation:

2K + (K - 7) - 12 = 35

3K - 19 = 35

Adding 19 to both sides:

3K = 54

Dividing both sides by 3:

K = 18

Now we can substitute the value of K into equation 1 to find L:

L = K - 7

L = 18 - 7

L = 11

Finally, we can find the value of N by substituting the values of K and L into equation 3:

K + L + N = 35

18 + 11 + N = 35

N = 35 - 18 - 11

N = 6

Therefore, Lucy has $11.

Answer:

\(x=-20\)

Step-by-step explanation:

We solve this by isolating the \(x\) on one side, and the numbers on the other.

\(\frac{x}{5} +9=5\)

\(\frac{x}{5} +9-9=5-9\)

\(\frac{x}{5}=-4\)

\(\frac{x}{5}*5=-4*5\)

\(x = -20\)

Answer:

\(\boxed {x = -20}\)

Step-by-step explanation:

Solve for the value of \(x\):

\(\frac{x}{5} + 9 = 5\)

-Multiply both sides by \(5\):

\(5 \times \frac{x}{5} + 9 = 5 \times 5\)

\(x + 45 = 25\)

-Subtract both sides by \(45\):

\(x + 45 - 45 = 25 - 45\)

\(\boxed {x = -20}\)

Therefore, the value of \(x\) is \(-20\).

The temperature at a given chirp rate can be determined from a linear regression model as follows;

a. The linear regression model is; T = 4.1484·C - 166.1

b. At 72 °F the chirp rate is approximately 57 chirps per minute

At 90 °F the chirp rate is approximately 62 chirps per minute

A linear regression model, models a relationship between variables using a linear approach

a. The data given the values of the temperatures at a  given chirp rate per minute is used to create the attached scatter plot.

From the scatter plot, a trend line is drawn using the Add Chart Element, within the Chart Tools, Design Menu.

From the Format Trendline window, The Display Equation on chart check box is selected, to show the trend line equation.

The trendline equation that is the linear regression model for chirp rate as a function of time is; y = 4.1484·x - 166.1

Where, y = T, and x = C, we have; T = 4.1484·C - 166.1

b. If the temperature, T, is 72 °F, we have;

T = 72 °F

72 = 4.1484·C - 166.1

\(C = \dfrac{72+166.1}{4.1484} \approx 57\)

If the temperature is 90 °F, the chirp rate is calculated as follows;

T = 90 = 4.1484·C - 166.1

\(C = \dfrac{90+166.1}{4.1484} \approx 62\)

No, [1 -2 1] is not an eigenvector of [3 3 5; 6 3 6; 7 7 5].

To determine if [1 -2 1] is an eigenvector of [3 3 5; 6 3 6; 7 7 5], we need to check if the given matrix multiplied by the vector is equal to a scalar multiple of the vector.

Let's perform the calculation:

[3 3 5; 6 3 6; 7 7 5] * [1; -2; 1] = [3 + (-6) + 5; 6 + (-6) + 6; 7 + (-14) + 5] = [2; 6; -2].

Since the result is not equal to a scalar multiple of [1 -2 1], we can conclude that [1 -2 1] is not an eigenvector of [3 3 5; 6 3 6; 7 7 5].

There is no corresponding eigenvalue for [1 -2 1] in this case.

Answer:

What forces act on the ball in the horizontal direction as it rolls? None. So that means there is no horizontal acceleration and therefore the horizontal component of the ball's speed is constant.

And since the ball was only travelling horizontally at the instant it rolled off the table, initially the vertical component of its speed is 0. That means the time taken to hit the ground after rolling off the table is the same as if it was just dropped 0.950 m. We can find this time using one of the kinematic equations of motion in the vertical direction, taking downwards as positive. Then we have the following information:

u = initial velocity = 0 m/s

d = distance fallen = 0.950 m

a = acceleration (due to gravity) = 9.8 m/s²

t = time = ?

d = ut + 1/2 at². Since u = 0 this reduces to d = 1/2 at² and rearranges to t = √(2d/a) = √(2*0.95/9.8) = 0.4403 s.

In the same amount of time, the ball travels a horizontal distance of 0.352 m. We already know the horizontal velcoity is constant, so horizontal velocity is just horizontal distance divided by time = (0.352 m)/(0.4403 s) = 0.799 m/s.

What is the payrate?

Step-by-step explanation:

The statistical technique that provides a numerical estimate of the maximum/worst loss that could be expected in a given time period with a given level of confidence or probability is value at risk (VaR).

VaR is commonly used in risk management to measure potential losses in financial portfolios or investments. It quantifies the amount of potential loss, typically expressed in monetary terms, that a portfolio may experience over a specified time horizon and at a certain level of confidence.

It helps investors and risk managers assess and control the potential downside risk associated with their investments. VaR takes into account the distribution of returns and the desired level of confidence to estimate the potential downside risk. Standard deviation and coefficient of variation are not direct measures of maximum loss but are related to risk assessment.

Step-by-step explanation:

First find the LCD or least common denominator. The least common denominator is the number that both of the denominators are divisible by.

In this case, 2 and 3 are both divisible by 6.

Convert both fractions into a fraction with a denominator of 6.

1/2 = 3/6 (multiply numerator and denominator by 3)

2/3 = 4/6 (multiply numerator and denominator by 2)

Now you can multiply as they have the same denominator.

Answer:

44%

Step-by-step explanation:

Suppose the original number is 100.

It is increased by 20 %, so the result will be 120.

The resulting number is again increased by 20%, which is increased by 120 *20/100, which is increased by 24. The final result will be 120+24 that is 144.

The final result is increased by 44 compared to the original number 100.

So, increase by 44%.

we have y≥2x-2 ------> inequality A

The inequality A is the solid red line in the graph the solution of the inequality A is the shaded area above the solid red line x+4y≥?------> inequality B The inequality B is the solid blue line in the graph the solution of the inequality B is the shaded area above the solid blue line we know that the point (0,-3) lie on the line of the inequality B. substitute the values of x and y in the equation of the line

x+4y=c

0+4*(-3)=c

c=-12

so the answer is -12

The system of linear inequalities is:

y > 2x – 2 and x + 4y > -12.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥  

We have,

When x = 0, y = 2(0) – 2 = -2.

So the point (0, -2) is on the line.

When x = 2, y = 2(2) – 2 = 2.

So point (2, 2) is on the line.

Plotting these two points and drawing a line through them gives us the graph of y = 2x – 2.

Next, let's graph x + 4y = -12 by solving for y:

x + 4y = -12

4y = -x - 12

y = (-1/4)x - 3

Again, we can plot two points on the line.

When x = 0, y = -3, giving us the point (0, -3).

When x = -4, y = -2, giving us the point (-4, -2).

Plotting these points and drawing a line through them gives us the graph of x + 4y = -12.

Thus,

The solution to the system of inequalities is the shaded region where the two graphs intersect and y > 2x – 2.

The net outward flux across the boundary of the tetrahedron is 5, using the concept of the gradient of a function.

The gradient  function in a vector field

The gradient function is related to a vector field and it is derived by using the vector operator ∇ to the scalar function f(x, y, z). The gradient is a fancy word for derivative or the rate of change of a function. It's a vector (a direction to move) that. Points in the direction of greatest increase of a function are zero at a local maximum or local minimum because there is no single direction of increase

Vector field:

F = ( -x, 3y, 2 z )

Δ . F = (i δ/δx + j δ/δy + k δ/δz) (-x, 3y, 2 z )

Δ . F = [δ/δx(-x)] + δ/δy (3y) + δ/δz (2z)]

Δ . F = - 1 + 3 + 2

Δ . F = 4

According to divergence theorem

Divergence Theorem

The divergence theorem states that the surface integral of the normal component of a vector point function F over a closed surface S is equal to the volume integral of the divergence. F  took over the volume V enclosed by the surface S. The divergence theorem says that when adding up all the little bits of outward flow in a volume using a triple integral of divergence, the total outward flow from that volume, as measured by the flux through its surface.

In 1990, a sample of a radioactive isotope had an initial mass of 110 mg and decayed exponentially over time.

A measurement in 1993 revealed that the sample's mass had decayed to 90

110 mg - 90 mg = 20 mg (amount decayed in the 3 total years)

20 mg ÷ 3 years = 6.6 mg decayed per year

Step-by-step explanation:

Therefore, the function f(x, y) is increasing most rapidly at point P_0(2, -1) in the direction of the vector (5, -8).

To find the direction in which the function \(f(x, y) = xy^2 - yx^2\) is increasing most rapidly at point P_0(2, -1), we can compute the gradient vector ∇f(x, y) and evaluate it at P_0.

First, let's find the gradient vector ∇f(x, y) by taking the partial derivatives of f(x, y) with respect to x and y:

∂f/∂x \(= y^2 - 2yx\)

∂f/∂y \(= 2xy - x^2\)

Now, let's evaluate the gradient vector at P_0(2, -1):

∇f(2, -1) = (∂f/∂x(2, -1), ∂f/∂y(2, -1))

= ( (-1)^2 - 2(2)(-1), 2(2)(-1) - 2^2 )

= ( 1 + 4, -4 - 4 )

= ( 5, -8 )

The gradient vector ∇f(2, -1) = (5, -8) represents the direction in which the function f(x, y) increases most rapidly at point P_0(2, -1).
