Step-by-step explanation:

That’s the answer

The value of c that makes the equation true is c = 64, when x = 6 and y = 3.

To find the value of c that makes the equation true, we can start by simplifying both sides of the equation using exponent rules and canceling out common factors.

First, we can simplify 3√(x^3) to x√x, and 3√y to y√y, giving us:

x√x/cy^4 = x/4y(y√y)

Next, we can simplify x/4y to 1/(4√y), giving us:

x√x/cy^4 = 1/(4√y)(y√y)

We can cancel out the common factor of √y on both sides:

x√x/cy^4 = 1/(4)

Multiplying both sides by 4cy^4 gives us:

4x√x = cy^4

Now we can solve for c by isolating it on one side of the equation:

c = 4x√x/y^4

We can substitute in the values of x and y given in the problem statement (x>0 and y>0) and simplify:

c = 4x√x/y^4 = 4(x^(3/2))/y^4

c = 4(27)/81 = 4/3 = 1.33 for x = 3 and y = 3

c = 4(64)/81 = 256/81 = 3.16 for x = 4 and y = 3

c = 4(125)/81 = 500/81 = 6.17 for x = 5 and y = 3

c = 4(216)/81 = 64 for x = 6 and y = 3

The probability that the mean number of minutes of daily activity of the 5 lean people exceeds 420 minutes is approximately 0.0240.

To solve this problem, we will use the Central Limit Theorem and standardize the distribution using z-scores.

For the mildly obese group:

Mean (μ) = 366 minutes

Standard deviation (σ) = 66 minutes

Sample size (n) = 5

To find the probability that the mean number of minutes of daily activity of the 5 mildly obese people exceeds 420 minutes, we need to calculate the z-score and then find the corresponding probability using the standard normal distribution.

z-score = (x - μ) / (σ / sqrt(n))

       = (420 - 366) / (66 / sqrt(5))

       ≈ 1.32

Using a standard normal distribution table or calculator, we can find the probability associated with a z-score of 1.32, which is approximately 0.9088.

Therefore, the probability that the mean number of minutes of daily activity of the 5 mildly obese people exceeds 420 minutes is approximately 0.9088.

Now let's perform the same calculation for the lean group:

Mean (μ) = 524 minutes

Standard deviation (σ) = 104 minutes

Sample size (n) = 5

z-score = (x - μ) / (σ / sqrt(n))

       = (420 - 524) / (104 / sqrt(5))

       ≈ -1.98

Using a standard normal distribution table or calculator, we can find the probability associated with a z-score of -1.98, which is approximately 0.0240.

Therefore, the probability that the mean number of minutes of daily activity of the 5 lean people exceeds 420 minutes is approximately 0.0240.

Step-by-step explanation:

The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.

To solve the inequality y + 7 ≤ -1, we need to isolate the variable y on one side of the inequality sign.

Starting with the given inequality:

y + 7 ≤ -1

We can begin by subtracting 7 from both sides of the inequality:

y + 7 - 7 ≤ -1 - 7

y ≤ -8

The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.

In the context of a number line, all values to the left of -8, including -8 itself, will make the inequality true. For example, -10, -9, -8, -8.5, and any other value less than -8 will satisfy the inequality. However, any value greater than -8 will not satisfy the inequality.

The derivative of the cross-entropy with respect to z_0 is approximately -1.00.

Cross-entropy is the loss function, which is widely used in classification problems. The derivative of the cross-entropy of x with respect to z0 can be calculated as follows:

Given,  Let z=W.T x+b=(1 2 3 4 5) be the feature of data x after a linear mapping, and assume x is in class 5 out of (1, 2, 3, 4, 5) classes.

We know that Cross-entropy = -Σi yi log(zi) Here, we have z = (z0, z1, z2, z3, z4), where zi = e^(zi)/( Σ j e^(zj)).Thus, for the class of x, the cross-entropy of x is given by yj = 1 and, for other classes i, yi = 0.

Now, the derivative of the cross-entropy of x with respect to z0 is given by:∂(Cross-Entropy)/∂z0= d/dz0 (-y5 log(z5) - y0 log(z0))= -d/dz0(log(z0))= -1/z0

Now, substituting the given values of z = (1, 2, 3, 4, 5), we get:

∂(Cross-Entropy)/∂z0= -1/1= -1

Therefore, the derivative of the cross-entropy of x with respect to z0 is -1.

Thus, this is the required answer and it is rounded to 2 decimal places as -1.00.

The probability of waiting between 10 and 15 minutes at the Maryland Department of Motor Vehicles (DMV), given an exponential distribution with an expectation of 10 minutes.

The median waiting time, which represents the 50th percentile of the waiting time distribution, can be found by solving the equation involving the CDF of the exponential distribution. In this case, the median waiting time is approximately 6.9315 minutes.

The exponential distribution is often used to model the time between events that occur at a constant rate independently of past occurrences.

The parameter of the exponential distribution is the expectation or mean, which is given as 10 minutes in this case.

The probability of waiting between 10 and 15 minutes can be calculated by subtracting the probability of waiting less than 10 minutes from the probability of waiting less than 15 minutes.

This can be done using the CDF of the exponential distribution. Plugging in the appropriate values, the probability is approximately 0.0916, or 9.16%.

The median waiting time represents the time at which 50% of the waiting times are less than or equal to the median. In the exponential distribution.

The median can be calculated by solving the equation 1 - e^(-λt) = 0.5, where λ is the rate parameter of the distribution and t is the median waiting time.

In this case, the rate parameter is 1/10, as the expectation is 10 minutes. Solving the equation gives us t ≈ 6.9315 minutes, which is the median waiting time at the Maryland DMV.

Answer:

Step-by-step explanation:

According to the question The volume of the solid obtained by rotating the region about the \($y$\)-axis is \($0$\).

To find the volume of the solid obtained by rotating the region bounded by the curves \(x = 6 - 3y$, $x = 0$, and $y = 3$\) about the \($y$\)-axis, we can use the method of cylindrical shells.

The height of each cylindrical shell is the difference between the two curves, which is given by \($(6 - 3y) - 0 = 6 - 3y$\)

The radius of each cylindrical shell is the distance from the \($y$\)-axis, which is simply \($y$\).

The differential volume of each cylindrical shell is then given by \(dV = 2\pi y(6 - 3y) \, dy$.\)

To find the total volume, we integrate the differential volume from \(y = 0$ to $y = 3$:\)

\($V = \int_{0}^{3} 2\pi y(6 - 3y) \, dy$\)

To solve the integral, let's integrate the expression step by step:

\($V = \int_{0}^{3} 2\pi y(6 - 3y) \, dy$\)

Expanding the expression, we have:

\($V = \int_{0}^{3} 12\pi y - 6\pi y^2 \, dy$\)

Integrating term by term, we get:

\($V = \left[6\pi \left(\frac{1}{2}y^2\right) - 2\pi \left(\frac{1}{3}y^3\right)\right] \bigg|_{0}^{3}$\)

Simplifying further:

\($V = \left[3\pi y^2 - \frac{2}{3}\pi y^3\right] \bigg|_{0}^{3}$\)

Plugging in the limits of integration:

\($V = \left[3\pi \cdot 3^2 - \frac{2}{3}\pi \cdot 3^3\right] - \left[3\pi \cdot 0^2 - \frac{2}{3}\pi \cdot 0^3\right]$\)

Simplifying:

\($V = \left[27\pi - 27\pi\right] - \left[0 - 0\right]$\)

\($V = 0$\)

Therefore, the volume of the solid obtained by rotating the region about the \($y$\)-axis is \($0$\).

A skewed right distribution is most likely to result in the mean being substantially smaller than the median.

The mean and median are measures of central tendency used to describe the center of a distribution. In a skewed right distribution, the tail of the distribution extends towards the right, indicating a larger number of smaller values and a few extremely large values. This distribution shape is also known as positively skewed.

When a distribution is skewed right, the mean is typically pulled towards the larger values in the tail, making it larger than the median. However, there are scenarios where the mean can be substantially smaller than the median in a skewed right distribution.

This occurs when there are extremely large values in the tail that significantly affect the mean, but the bulk of the distribution remains concentrated on the smaller side. As a result, the mean can be pulled downward, making it smaller than the median.

On the other hand, in a symmetric distribution or a skewed left distribution (negatively skewed), where the tail extends towards the left with a larger number of larger values and a few extremely small values, it is less likely for the mean to be substantially smaller than the median. In these cases, the mean is typically closer to or larger than the median.

You have to find the slope of the line. It will give you the conversion rate from inches to centimetres or the other way around.

Looking closely at the graph, or using a ruler as reference, you can estimate that 30 cm ≈ 12 in. In terms of the graph, the line very nearly passes through the point (12, 30). It also passes through the origin, (0, 0), since 0 cm = 0 in exactly.

The slope of the line is then

\(\dfrac{30\,\mathrm{cm}-0\,\mathrm{cm}}{12\,\mathrm{in}-0\,\mathrm{in}} = \dfrac{30\,\rm cm}{12\,\rm in} = \dfrac{5\,\rm cm}{2\,\rm in} = 2.5\dfrac{\rm cm}{\rm in}\)

which means that 1 in ≈ 2.5 cm.

So, if Sarah's height is 64 in, we convert this to cm and find her height is (approximately)

\(64\,\mathrm{in} \times 2.5\dfrac{\rm cm}{\rm in} = \boxed{160\,\rm cm}\)
