Answer:

Number of dogs = 6

Number of burgers = 11

Step-by-step explanation:

Number of dogs = x

Number of burgers = 2x - 1

Cost of a dog = $ 1.50

Cost of 'x' dogs = 1.5x

Cost of a burger = $ 2

Cost of (2x - 1) burger = (2x -1) * 2 = 2x *2 - 1*2

                                    = 4x - 2

Total amount collected  = $ 31

1.5x + 4x - 2 = 31 {add 2 to both sides}

        1.5x + 4x = 31 + 2

      1.5x+ 4x  = 33

               5.5x = 33

                    x = 33/5.5

                   x = 6

Number of dogs  = 6

Number of burgers = 2*6 - 1 = 12 - 1 = 11

Answer:

\(f'(x)= \frac{13}{(2x+3)^2}\\\)

Step-by-step explanation:

\(f(x)= \frac{3x-2}{2x+3} \\\)

\(f'(x)=\frac{dy}{dx} = \frac{d}{dx}(\frac{3x-2}{2x+3})\\ f'(x)= \frac{(2x+3)\frac{d}{dx}(3x-2)-(3x-2)\frac{d}{dx}(2x+3) }{(2x+3)^{2} } \\f'(x)= \frac{(2x+3)(3)-(3x-2)(2)}{(2x+3)^{2} } \\\)

Given that John surfs the website on a regular basis. The time he spent surfing the website per day is normally distributed, µ = 8 minutes and σ = 2 minutes. If you select a random sample of 4 sessions. We are to find the probability of sample mean.a.

The probability that the sample mean is less than 8 minutes sample size(n) = 4μ = 8 minutesσ = 2 minutes

As we know, the sample means follow a normal distribution with mean, μ and standard deviation, σ / sqrt(n).

Therefore, the sample mean will follow a normal distribution with a mean of μ and standard deviation of σ/√n=2/√4=1

So the Z-score for the given data can be calculated as: Z= X−μ/σ/√nZ= 8−8/2/√4=0Thus, the probability that the sample mean is less than 8 minutes is P(Z < 0).

Since the Z distribution is normal, the area to the left of 0 is 0.5.

Therefore, the probability that the sample mean is less than 8 minutes is 0.5.b. The probability that the sample mean is between 8 and 10 minutes sample size(n) = 4μ = 8 minutesσ = 2 minutes

The Z-scores corresponding to X1=8 and X2=10 can be calculated as: Z1= X1−μ/σ/√n= 8−8/2/√4=0Z2= X2−μ/σ/√n= 10−8/2/√4=1

Thus, the probability that the sample mean is between 8 and 10 minutes is the area under the standard normal curve between Z1 and Z2, which is P(0

The missing value in the ordered pair (−10,?) is 7.

To find the missing value in the ordered pair (−10,?), we can substitute the given value of x, which is −10, into the equation x + 10y = 60 and solve for y.
Let's substitute x = -10 into the equation:
-10 + 10y = 60
Now, let's solve for y. To isolate y, we need to move -10 to the other side of the equation:
10y = 60 + 10
Adding 10 to both sides of the equation gives us:
10y = 70
To find the value of y, we divide both sides of the equation by 10:
y = 70/10
y = 7

Therefore, the missing value in the ordered pair (−10,?) is 7.

Step-by-step explanation:

\( \frac{1}{2} x = 5 \\ x = 10\)

79.50 = 46 + 6.70t

33.50 = 6.70 t

t = 5 hours

By evaluating the function, we conclude that f(10) = -7

Here we know that:

g(x) = 2x - 8

And f(x) = 5 - g(x).

Then we can write:

f(x) = 5 - (2x - 8) = 5 - 2x + 8 = -2x + 13

Now we want ot evaluate it in x = 10, this means replace the variable by the number 10.

f(10) = -2*10 + 13 = -20 + 13 = -7

To determine the upstream throat area, stagnation temperature, and mass flow in the system of a converging-diverging nozzle, we need to apply the equations of fluid dynamics. Given the downstream test section parameters of area (A) = 53 cm^2, pressure (p) = 12 kPa, density (rho) = 0.182 kg/m^3, and velocity (V) = 760 m/s, we can calculate the required values.

(a) The upstream throat area (A*) can be determined using the mass flow rate equation, which states that mass flow rate (m_dot) is equal to the product of density, velocity, and area: m_dot = rho * V * A. Rearranging the equation, we have A* = m_dot / (rho * V). Substituting the given values, we find A* = 0.733 kg/s / (0.182 kg/m^3 * 760 m/s) = 0.002 m^2.

(b) The stagnation temperature (T0) can be calculated using the isentropic relations. We need to use the specific heat ratio (gamma) of the gas, which is typically given for a specific fluid. Assuming a value of gamma = 1.4 for air, the relation is T0 = T / (1 + (gamma - 1) / 2 * M^2), where T is the static temperature and M is the Mach number. Given the information provided, we don't have the static temperature or Mach number, so we cannot calculate the stagnation temperature.

(c) The mass flow rate (m_dot) is already given as 0.733 kg/s.

In summary, we have determined the upstream throat area (A*) to be 0.002 m^2 and the mass flow rate (m_dot) to be 0.733 kg/s. However, we couldn't calculate the stagnation temperature (T0) without additional information about the static temperature and Mach number.

The covariance of their returns is approximately 0.0149601.

To calculate the covariance of the returns of two stocks, we need to multiply the difference between each pair of corresponding returns by the probability of each state, and then sum up these products. The formula for covariance is as follows:

Covariance = (Return_A1 - Mean_Return_A) * (Return_B1 - Mean_Return_B) * Probability_1

          + (Return_A2 - Mean_Return_A) * (Return_B2 - Mean_Return_B) * Probability_2

Where:

- Return_A1 and Return_A2 are the returns of stock A in state 1 and state 2, respectively.

- Return_B1 and Return_B2 are the returns of stock B in state 1 and state 2, respectively.

- Mean_Return_A and Mean_Return_B are the mean returns of stock A and stock B, respectively.

- Probability_1 and Probability_2 are the probabilities of state 1 and state 2, respectively.

Let's calculate the covariance:

Return_A1 = 1%

Return_A2 = 80%

Return_B1 = 12%

Return_B2 = -10%

Probability_1 = 0.85

Probability_2 = 0.15

Mean_Return_A = (Return_A1 * Probability_1) + (Return_A2 * Probability_2)

             = (0.01 * 0.85) + (0.8 * 0.15)

             = 0.0085 + 0.12

             = 0.1285

Mean_Return_B = (Return_B1 * Probability_1) + (Return_B2 * Probability_2)

             = (0.12 * 0.85) + (-0.1 * 0.15)

             = 0.102 - 0.015

             = 0.087

Covariance = (Return_A1 - Mean_Return_A) * (Return_B1 - Mean_Return_B) * Probability_1

          + (Return_A2 - Mean_Return_A) * (Return_B2 - Mean_Return_B) * Probability_2

          = (0.01 - 0.1285) * (0.12 - 0.087) * 0.85

          + (0.8 - 0.1285) * (-0.1 - 0.087) * 0.15

          = (-0.1185) * (0.033) * 0.85

          + (0.6715) * (-0.187) * 0.15

          = -0.00489825 + 0.01985835

          = 0.0149601

To calculate the correlation of their returns, we divide the covariance by the product of the standard deviations of the returns of each stock. The formula for correlation is as follows:

Correlation = Covariance / (Standard_Deviation_A * Standard_Deviation_B)

Let's assume the standard deviations of the returns for stock A and stock B are known. If we use σ_A for the standard deviation of stock A and σ_B for the standard deviation of stock B, we can substitute these values into the formula to calculate the correlation. However, if you provide the standard deviations, I can provide a more accurate calculation.

             \(= 27x^3 - 1-3(9x^2)+ 9x\\\\=27x^3 -27x^2 +9x -1\)

The expanded form of the function f(x) = (3x - 1)³ is 27x³ - 9x² + 9x - 1.

We have,

To expand the function f(x) = (3x - 1)³, we can use the binomial expansion formula, which states:

(a + b)³ = a³ + 3a²b + 3ab² + b³

In this case,

a = 3x and b = -1.

Substituting these values into the formula, we get:

\((3x - 1)^3 = (3x)^3 + 3(3x)^2(-1) + 3(3x)(-1)^2 + (-1)^3\)

Simplifying further:

(3x - 1)³ = 27x³ - 9x³ + 9x - 1

Therefore,

The expanded form of the function f(x) = (3x - 1)³ is 27x³ - 9x² + 9x - 1.

What is circle?

A circle is a geometric shape that consists of all points in a plane that are equidistant from a fixed point called the center.

To solve this problem, we need to find the area of the trapezoid and subtract the area of the semicircle.

The area of a trapezoid is given by the formula:

A = (a + b)h/2

where a and b are the lengths of the parallel sides, and h is the height (the perpendicular distance between the parallel sides).

In this case, we have:

a = 24 inches (the top parallel side)

b = 16 inches (the bottom parallel side)

h = 12 inches (the height)

Using the formula, we get:

A = (24 + 16) x 12/2

A = 240 square inches

The area of a semicircle is given by the formula:

A = πr²/2

where r is the radius of the circle.

In this case, the radius is half of the length of the wiper, so we have:

r = 16/2 = 8 inches

Using the formula, we get:

A = π(8²)/2

A ≈ 100.5 square inches

Therefore, the approximate area of the window that is not cleaned by the wiper is:

240 - 100.5 ≈ 139.5 square inches. Answer: \boxed{139.5}.
