Step-by-step explanation:

Answer:

12.4

Step-by-step explanation:

The probability that one bill for veterinary services costs between $53 and $125 is  0.866383

The probability that one bill for veterinary services costs between $42 and $133 will be given as follows P(53<x<125), Since the formula for calculating the z score is

z=(x-μ)/σ, where  μ is the mean, σ is the standard deviation

since we are provided with means of $89 and a standard deviation of $24.So the z score will be  :

for x =  53, z=(53-89)/24= -1.5

Therefore the probability  P(x<53) is  0.066807

Again for x = $125, x=(125-88)/24=1.54

Therefore , the probabiltiy P(x<125) is 0.93319

The probability that one bill for veterinary services costs between $53 and $125, P(53<x<125) is :

=0.93319-  0.066807

=0.866383

Wave interference that results in greater wave amplitude is called Constructive interference.

What is Wave Interference?

Wave interference is a physical phenomena that occurs when two waves collide while traveling through the same medium. Waves interact in two ways.

a) Constructive Interference - In this case, the two waves cancel each other out because their amplitudes are equal and opposite.

b) Destructive Interference - This occurs when two waves add to each other as they travel in the same direction, resulting in a wave with a longer wavelength.

It is Constructive interference.

Therefore, Wave interference that results in greater wave amplitude is called Constructive interference.

Step-by-step explanation:

The line integral ∫F⋅dr with the lower limit \(C_{1}\) is 52/15 and ∫F⋅dr with the lower limit \(C_{2}\) is 10/3. F is not a gradient vector field. F is not conservative.

To compute the line integrals, we need to parameterize the given curves \(C_{1}\)(t) and \(C_{2}\)(t) and then evaluate the dot product between the vector field F and the tangent vector dr. Let's calculate each line integral:

For \(C_{1}\)(t) = (t, \(t^{2}\)):

The tangent vector d\(r_{1}\) = (d\(x_{1}\) , d\(y_{1}\) ) = (dt, 2t dt)

The dot product F⋅d\(r_{1}\) = (\(x^{2}\) + \(y^{2}\)) d\(x_{1}\)  + (8xy) d\(y_{1}\)

= (\(t^{2}\) + \(t^{4}\) ) dt + (8t(\(t^{2}\))) (2t dt)

= (\(t^{2}\) + \(t^{4}\) + 16\(t^{4}\) ) dt

= (17\(t^{4}\)  + \(t^{2}\)) dt

Integrating (17\(t^{4}\)  + \(t^{2}\)) with respect to t from 0 to 1:

∫(17\(t^{4}\)  + \(t^{2}\)) dt = [ (17/5)\(t^{5}\) + (1/3)\(t^{3}\) ] evaluated from 0 to 1

= (17/5) + (1/3) - 0

= 17/5 + 1/3

= 52/15

The line integral ∫F⋅dr with the lower limit \(C_{1}\) is 52/15.

For \(C_{2}\) (t) = (t, t):

The tangent vector d\(r_{2}\) = (d\(x_{2}\) , d\(y_{2}\) ) = (dt, dt)

The dot product F⋅ d\(r_{2}\) = (\(x^{2}\) + \(y^{2}\)) d\(x_{2}\) + (8xy)  d\(y_{2}\)

= ( \(t^{2}\) +\(t^{2}\)) dt + (8t(t)) dt

= (2\(t^{2}\)  + 8\(t^{2}\) ) dt

= 10\(t^{2}\)  dt

Integrating 10 \(t^{2}\)  with respect to t from 0 to 1:

∫10 \(t^{2}\)  dt = (10/3) \(t^{3}\)  evaluated from 0 to 1

= (10/3) - 0

= 10/3

The line integral ∫F⋅dr with the lower limit  \(C_{2}\) is 10/3.

To determine whether F is a gradient vector field, we need to check if its line integrals are path-independent (i.e., the line integrals are only dependent on the endpoints and not the path taken). If the line integrals are path-independent, then F is a conservative vector field and can be expressed as the gradient of a scalar potential function.

From our calculations, we observe that the line integrals for \(C_{1}\) and  \(C_{2}\) are different. Therefore, F is not a conservative vector field and cannot be expressed as the gradient of a scalar potential function.

In summary:

The line integral ∫F⋅dr with the lower limit C1 is 52/15.

The line integral ∫F⋅dr with the lower limit  \(C_{2}\) is 10/3.

F is not a gradient vector field since its line integrals depend on the path taken.

F is not conservative.

Correct Question :

Consider The Vector Field F=(\(x^{2}\)+\(y^{2}\),8xy). Compute The Line Integrals ∫F⋅dr with lower limit C1 And ∫F⋅dr with lower limit  \(C_{2}\), Where \(C_{1}\)(t)=(t,\(t^{2}\)) And \(C_{2}\)(t)=(t,t) For 0≤t≤1.  Can you decide from your answers whether or not F is a gradient vector field?

The average rate of change of the function f(x) on the interval 0 ≤ x ≤  3 is 4.17

The equation of the function is given as:

y = f(x)

The graph of the function f(x) is added as an attachment

From the attached graph, we have the following function values at the given interval

f(0) = -5

f(3) = 7.5

The average rate of change of the function f(x) on the interval 0 ≤ x ≤  3 is calculated using:

Average rate of change = [f(b) - f(a)]/[b - a]

Where

(a, b) = (0, 3)

So, we have:

Average rate of change = [f(3) - f(0)]/[3 - 0]

Substitute the known values in the above equation

Average rate of change = [7.5 - -5]/[3 - 0]

Evaluate the difference

Average rate of change = [12.5]/[3]

Evaluate the quotient

Average rate of change = 4.17

Hence, the average rate of change of the function f(x) on the interval 0 ≤ x ≤  3 is 4.17

Approximately 89.26% of utility companies have revenue between 41 million and 99 million dollars. We need to use the normal distribution formula and find the z-scores for the given values.

First, we need to find the z-score for the lower limit of the range (41 million dollars):  z = (41 - 70) / 18 = -1.61
Next, we need to find the z-score for the upper limit of the range (99 million dollars): z = (99 - 70) / 18 = 1.61
We can now use a standard normal distribution table or a calculator to find the area under the curve between these two z-scores. The area between -1.61 and 1.61 is approximately 0.9044. This means that approximately 90.44% of utility companies earned revenue between 41 million and 99 million dollars.


To find the percentage of utility companies with revenue between 41 million and 99 million dollars, we can use the z-score formula and the standard normal distribution table. The z-score formula is: (X - mean) / standard deviation. First, we'll calculate the z-scores for both 41 million and 99 million dollars: Z1 = (41 million - 70 million) / 18 million = -29 / 18 ≈ -1.61
Z2 = (99 million - 70 million) / 18 million = 29 / 18 ≈ 1.61
Now, we'll look up the z-scores in the standard normal distribution table to find the corresponding percentage values.
For Z1 = -1.61, the table value is approximately 0.0537, or 5.37%.
For Z2 = 1.61, the table value is approximately 0.9463, or 94.63%.
Percentage = 94.63% - 5.37% = 89.26%

Answer:

Two or more equations using the same variable are referred to mathematically as a "system of linear equations." These equations' solutions serve as a representation of the intersection of the lines.

Two equations are presented here:

1) x + 3y = 7

2) 2x + 4y = 8

First, in the first equation, we want to isolate x:

x + 3y = 7

x = 7 -3y

In order to create an equation that depends just on the variable y, we must now b) swap it out in the second equation.

2x + 4y = 8

2(7 - 3y) + 4y = 8

The value of y is now determined by solving this equation in step (c).

14 - 6y + 4y = 8

14 - 2y = 8

-2y = 8 - 14 = -6

y= 6/2= 3

d) With the value of y now available, we can change the equation we obtained in step a) by substituting it.

x = 7 - 3y

x = 7 - 3*3 = 7 - 9 = -2

Answer c

Step-by-step explanation:

The solution for y' is y' = (-2xy) / (x + y)^2.

We can treat y' as a variable and rearrange the equation in terms of y' on one side:

-5(x + y)^2 - 5(x + y)^2y' + 5y^2y' = -5x^2

let's combine like terms:

-5(x + y)^2(1 + y') + 5y^2y' = -5x^2

Now, let's isolate the y' terms on one side by moving the other terms to the other side:

-5(x + y)^2(1 + y') = -5x^2 - 5y^2y'

Divide both sides by -5(x + y)^2:

1 + y' = (x^2 + y^2) / (x + y)^2

Now, subtract 1 from both sides:

y' = (x^2 + y^2) / (x + y)^2 - 1

Simplifying:

y' = (x^2 + y^2 - (x + y)^2) / (x + y)^2

Expanding (x + y)^2:

y' = (x^2 + y^2 - (x^2 + 2xy + y^2)) / (x + y)^2

y' = (x^2 + y^2 - x^2 - 2xy - y^2) / (x + y)^2

y' = (-2xy) / (x + y)^2

Therefore, the solution for y' is y' = (-2xy) / (x + y)^2.
