Step-by-step explanation:

SA=2(wl+hl+hw)

2·(6·2+9·2+9·6)

=168

Step-by-step explanation:

since 1 yard =3feet

then 100yards= 300feet

which means 100yards=300feet=12seconds

let B be the number of feet in 8seconds

if 300feet=12seconds

then B feet= 8 seconds

if we cross multiply

300×8=12×B

2400=12B

B=2400/12

B= 200feet

OR

put it in ratio

feet/it's sec= feet/it's sec

300/12=B/8

then cross multiply to get your answer.

The new mean after removing the outliers is approximately 231.14.

The mean of the data set with outliers is 267, and there are 6 outliers with a mean of 688. To find the new mean after removing the outliers, we need to subtract the total value of the outliers from the total value of the original data set and then divide by the remaining number of data points.

Let's start by finding the total value of the original data set. We know that the mean is 267 and there are 100 data points, so the total value is:

267 x 100 = 26700

Next, we need to find the total value of the outliers. We know that there are 6 outliers with a mean of 688, so the total value of the outliers is:

688 x 6 = 4128

Now we can subtract the total value of the outliers from the total value of the original data set to find the total value of the remaining data points:

26700 - 4128 = 22572

Finally, we can divide the total value of the remaining data points by the number of remaining data points to find the new mean:

(22572)/(100-6) = 231.14

Therefore, the new mean after removing the outliers is approximately 231.14.

We can conclude that it is extremely unlikely to obtain a sample mean greater than 904.8 minutes if the design engineer's claim about the population variance and mean is true.

We can use the Central Limit Theorem to approximate the distribution of the sample means.

Under the given assumptions, the mean of the sampling distribution of the sample means is equal to the population mean, which is 886886 minutes, and the standard deviation of the sampling distribution of the sample means is equal to the population standard deviation divided by the square root of the sample size, which is[tex]\sqrt{84648464/145145} = 41.77[/tex] minutes.

Therefore, we can standardize the sample mean using the formula:

[tex]z = (\bar{x} - \mu) / (\sigma / \sqrt{n } )[/tex]

where [tex]\bar{x}[/tex]  is the sample mean, [tex]\mu[/tex]  is the population mean, sigma is the population standard deviation, and n is the sample size.

Plugging in the values we get:

z = (904.8 - 886886) / (41.77) = -21115.47

The probability of getting a sample mean greater than 904.8 minutes can be calculated as the area under the standard normal curve to the right of z = -21115.47.

This probability is essentially zero, since the standard normal distribution is symmetric and nearly all of its area is to the left of -6.

Gradient descent cannot be used directly for classifying error in classification because the error rate is not a smooth function of the model parameters and gradients cannot be computed.

Gradient descent is an optimization algorithm that is commonly used in machine learning to minimize a cost function. The cost function is a measure of how well the model performs on the training data, and the goal of the optimization algorithm is to find the model parameters that minimize this cost function.

In classification tasks, the cost function is typically a measure of the error rate or misclassification rate of the model. However , the error rate is not a smooth function of the model parameters, and it is not possible to compute gradients with respect to the model parameters. This makes it difficult to use gradient descent directly for optimizing the parameters of a classification model.

Instead, specialized optimization algorithms such as stochastic gradient descent (SGD) and its variants are used to train classification models. These algorithms are designed to work with non-smooth, non-convex cost functions and are able to handle the discrete nature of the output labels in classification tasks. Additionally, other metrics such as accuracy, precision, recall, and F1 score can be used as evaluation metrics instead of the error rate.

The probability that at least one student fails STA 2023 in their first try when selecting three students at random is 0.271.

To solve this problem, we can use the complement rule. The complement rule states that the probability of an event happening is equal to 1 minus the probability of the event not happening.

First, let's find the probability that none of the three students fail the course in their first try. This is (0.9)^3 since the probability of a student passing is 1 minus the probability of failing, which is 0.1. Therefore:

Probability of none failing = (0.9)^3 = 0.729

Now, we can use the complement rule to find the probability that at least one student fails:

Probability of at least one failing = 1 - Probability of none failing
Probability of at least one failing = 1 - 0.729
Probability of at least one failing = 0.271

Therefore, the probability that at least one of the three students fails the course in their first try is 0.271.

Answer:

7 - 2m can be translated to "7 minus two times m" or "the difference between 7 and twice m".

3(m + 2) = 15 can be translated to "three times the sum of m and 2 is equal to 15" or "the product of 3 and the sum of m and 2 is 15".

To solve the equation, we can start by distributing the 3 on the left side:

3(m + 2) = 15

3m + 6 = 15

Then, we can subtract 6 from both sides:

3m + 6 - 6 = 15 - 6

3m = 9

Finally, we can divide both sides by 3:

3m/3 = 9/3

m = 3

Therefore, the solution to the equation 3(m + 2) = 15 is m = 3.

5m - m(2 - m) can be translated to "5m minus the product of m and the difference between 2 and m" or "the difference between 5m and m times the quantity 2 minus m".

To simplify the expression, we can use the distributive property to expand the second term:

5m - m(2 - m) = 5m - 2m + m^2 = m^2 + 3m

Therefore, the simplified expression is m^2 + 3m.

The expression with the greater value is the second one:

log₀.₅(4)

Here we have two logarithms whose base are 0.5.

Remember that a logarithm of base a can be rewritten as follows:

log₀.₅(4)

We can rewrite these as:

ln(6)/ln(0.5)

Answer:

The inverse function of a trigonometric function, such as the sine, is called arcsine or sin^-1. To show that the inverse function of sine, sin^-1(x), and the value of x when y = sin(x) are inverses, we can use the definition of the inverse function.

When y = sin(x), this means that x = sin^-1(y). Substituting sin(3π/4) in place of y gives x = sin^-1(sin(3π/4)).

Using the trigonometric identity of the inverse function, we have that:

cos^-1(cos(x)) = x

This means that sin^-1(sin(3π/4)) = 3π/4. Therefore, x = sin^-1(sin(3π/4)) + 3π/4, which means that the value of x is equal to the sum of sin^-1(sin(3π/4)) and 3π/4.

In summary, it can be shown that sin^-1(sin(3π/4)) + 3π/4 = 3π/4, which shows that the inverse function of sine and the value of x when y = sin(x) are reverse. This is because the inverse sine function takes the y value and returns the corresponding x value, and the sine function takes the x value and returns the corresponding y value.

The relationship between wavelength and period is such that as the wavelength of a wave increases, its period also increases, given that the wave speed remains constant. This means that longer wavelengths result in longer periods, while shorter wavelengths correspond to shorter periods.

Mathematically, this relationship is expressed through the formula v = λf, where v represents the wave speed, λ is the wavelength, and f is the frequency. Since frequency (f) is the reciprocal of period (T), i.e., f = 1/T, we can rewrite the formula as v = λ(1/T). By rearranging this equation, we can find the relationship between wavelength and period: λ = vT.

In summary, the relationship between wavelength and period is directly proportional, with longer wavelengths resulting in longer periods and vice versa, given a constant wave speed. The mathematical relationship is expressed as λ = vT, where λ is the wavelength, v is the wave speed, and T is the period.

The relationship between two integers a and b, where a is a divisor of b, can be expressed using the existential quantifier. We can say that "a divides b" if and only if there exists an integer k such that:

b = ak

In other words, a divides b if and only if there exists an integer k such that b can be expressed as the product of a and k.

We can also express this relationship using the universal quantifier by saying that for all integers a, b, and k:

a divides b if and only if b = ak for some integer k
