Step-by-step explanation:

On a negatively skewed curve The mean is lower than the median which is lower than the mode. The correct answer is E.

In statistics, a distribution is said to be negatively skewed if more values are concentrated on the right side (tail) of the distribution graph and the left tail is longer.

Positive skew is characterized by a longer or fatter tail on the right side of the distribution, and negative skew is characterized by a longer or fatter tail on the left. These two skews represent the direction or weight of the distribution.

The central tendency of a distribution is defined as its mean, median, and mode. The fact that the mean, median, and mode of the typically skewed data are all equal demonstrates the equality of wealth and income distribution as well as the significance of governmental policies and economic progress.

The distributions have a wide gap because the negative side is so heavily weighted. For instance, the data shows that the distribution of income is unequal and negatively skewed, and the central tendency is as follows:

Mode > Median > Mean.

Proportion should a 20% cream be mixed with a 5% cream of the same active ingredient to make a 10% cream the proportion in which the 20% cream should be mixed with the 5% cream to make a 10% cream is X:Y = 1:2.

To determine the proportion in which a 20% cream should be mixed with a 5% cream to make a 10% cream, we can once again use the concept of weighted averages.

Let's assume we mix X parts of the 20% cream with Y parts of the 5% cream.

The equation for the weighted average can be written as:

(Percentage A * Weight A) + (Percentage B * Weight B) = Desired Percentage * Total Weight

In this case, the equation would be:

(20% * X) + (5% * Y) = 10% * (X + Y)

Simplifying the equation, we get:

0.2X + 0.05Y = 0.1X + 0.1Y

Rearranging the terms, we have:

0.1X = 0.05Y

Dividing both sides by 0.05Y, we get:

(0.1X) / (0.05Y) = 1

Simplifying further:

2X = Y

Therefore, the proportion in which the 20% cream should be mixed with the 5% cream to make a 10% cream is X:Y = 1:2.

Answer: x=68

Step-by-step explanation:

A. It’s asking what the last test must have to be (x) for all five tests to average out to an 80. This can be represent by:

(95+76+77+84+x)/5=80

The first four numbers are the existing test scores and x is the score you need. This is all divided by five so that you can find the average of all of these added together, which will equal 80, because that’s the grade you’re trying to get. Next, just solve for x:

= 95+76+77+84+x=80(5)

= 332+x=400

X=68

B. I got 74 for this one by using the same process as in part a, but I divided the left side by six and multiplied x by two: (95+76+77+84+2x)/6=80

But I’m not completely positive about this answer. A is definitely right though

We have to find the value of  `(sinθ+cosθ−tanθ)/(secθ+cscθ−cotθ)`

Let's find all trigonometric ratios:

We can say that:

\($$\tan \theta= \frac{opp}{adj}= \frac{-4}{3}$$$$\text\)

{Using the Pythagorean Theorem we can find the hypotenuse }

\($$$$\text{Hypotenuse = } \sqrt{(-4)^2+(3)^2}\)

\(= \sqrt{16+9}\)

= \(\sqrt{25}\)

=\(5$$$$\)

Substituting the values of sinθ, cosθ and tanθ in `

\(= \frac{\frac{3}{5} + \frac{-4}{5} - \frac{-4}{3}}{\frac{-4}{5} + \frac{5}{3} - \frac{-3}{4}}$$$$\)

\(=\frac{\frac{9}{15} + \frac{-12}{15} + \frac{20}{15}}{\frac{-16}{20} + \frac{25}{12} + \frac{3}{4}}$$$$\)

\(=\frac{\frac{17}{15}}{\frac{-14}{15}}$$$$\)

\(=-\frac{17}{14}$$\)

Therefore, \(`(sinθ+cosθ−tanθ)/(secθ+cscθ−cotθ)\)` is equal to

`-17/14` when `tanθ=−43` (Quadrant II).

The answer to your question is the volume of the cylindrical hotel. The long answer requires an explanation of how to find this volume.

To find the volume of a cylinder, we use the formula V = πr^2h, where V is the volume, r is the radius (which is half the diameter), and h is the height.
First, we need to find the radius of the cylinder. We know the diameter is 150 ft, so the radius is 75 ft (half of 150).
Next, we can plug in the given values for the height and radius into the formula:
V = π(75)^2(427)
Simplifying this expression, we get:
V = 2,023,150π cubic feet
So the volume of the cylindrical hotel is approximately 6,349,716 cubic feet (rounded to the nearest whole number).

The general syntax for regression modeling in R is as follows:

lab5.reg4 = lm(formula, data = dataset)

summary(lab5.reg4)

In the first line, "formula" should be replaced with the regression formula that defines the relationship between the dependent variable and the independent variables. The formula should be written using the appropriate variables and operators, such as "+" for addition, "-" for subtraction, "*" for multiplication, and "/" for division. For example, a simple linear regression formula could be written as "y ~ x" to represent the dependent variable y and the independent variable x.

In the second line, "dataset" should be replaced with the name of the dataset being used for the regression analysis. The dataset should be properly imported or defined in R before running the regression model.

After running the regression model, the "summary" function is used to obtain a summary of the regression results, including the coefficients, standard errors, p-values, and other relevant statistics.

It is important to note that the specific variables and dataset used in the regression model will determine the actual syntax used. The syntax provided above serves as a general template, and you should fill in the blanks with the appropriate variables and dataset to generate the regression model and summary statistics for your specific analysis.

Signal a) is not absolutely band-limited and so, its Nyquist sampling rate cannot be determined. Signal b) is absolutely band-limited with an absolute bandwidth of B Hz, and its Nyquist sampling rate is 2B.

Let x(l) be a band-limited signal with absolute bandwidth B Hz. For each of the signals below, we need to determine whether the signal is absolutely band-limited, and if so, express the Nyquist sampling rate for the signal in terms of B.

a) x(0) + x(t - 1)dx(t)dt:For this signal, let us apply the Fourier transform. The Fourier transform of the first term is 2πX(ω)δ(ω), and that of the second term is e^(-jω)X(ω).

Thus, X(ω) = 2πX(ω)δ(ω) + e^(-jω)X(ω)On rearranging this expression, we get: X(ω) = [1 / (1 - 2πδ(ω))]e^(-jω)Therefore, the signal is not absolutely band-limited because it has components at all frequencies.

Hence, the Nyquist sampling rate cannot be determined.b) x:For this signal, let us consider its Fourier transform. Its Fourier transform will be a scaled version of the Dirac comb function, centered at ω = 0, with a spacing of 2π. Hence, X(ω) = 2πBδ(ω).

The signal is absolutely band-limited with absolute bandwidth B Hz, and hence, the Nyquist sampling rate will be 2B. The Nyquist sampling rate is twice the absolute bandwidth, and so, the sampling rate for this signal will be 2B Hz.

Thus, the answer to the question is as follows:Signal a) is not absolutely band-limited and so, its Nyquist sampling rate cannot be determined. Signal b) is absolutely band-limited with an absolute bandwidth of B Hz, and its Nyquist sampling rate is 2B.

  (c)  x ≤ 5 or x ≥ 7

Step-by-step explanation:

You want the solution to |x -6| ≥ 1.

The absolute value relation represents two relations, one for the domain x < 6, and one for the domain x ≥ 6.

In this domain, the inequality becomes ...

  -1 ≥ x -6

  5 ≥ x . . . . . . add 6

  x ≤ 5 . . . . . . . put x on the left

In this domain, the inequality is ...

  x -6 ≥ 1

  x ≥ 7

The disjoint solution sets are x ≤ 5 or x ≥ 7.

__

Additional comment

For |x -a| ≤ b, we can "unfold" this to the compound inequality ...

  -b ≤ (x -a) ≤ b

copying the inequality symbol to the left side, and writing the opposite of the constant there.

We can do the same thing with the inequality ...

  |x -a| ≥ b

but it doesn't really make sense as a compound inequality.

Instead, we have to write it as ...

  -b ≥ (x -a)   or   (x -a) ≥ b

in recognition of the fact that the solution spaces are disjoint.
