75% of the eruptions lasted between 1.77 and 4.93 minutes.

Chebyshev's Theorem calculates the proportion of observations that are within a given number of standard deviations of the mean. This theorem is applicable to many different probability distributions. Chebyshev's inequality is another name for Chebyshev's theorem.

According to Chebyshev’s theorem, the proportion of the data lying within k standard deviations of the mean is always at least 1 – 1/k^2, where k>1.

Given

Mean = 3.35

SD = 0.79

Mean – 1*SD = 3.35 – 1*0.79

= 3.35 – 0.79

= 2.56

Mean + 1*SD =3.35 + 1*0.79

= 3.35 + 0.79

= 4.14

Mean – 2*SD =3.35 – 2*0.79

= 3.35 – 1.58

= 1.77

Mean + 2*SD =3.35 + 2*0.79

= 3.35 + 1.58

= 4.93

Here, we have k = 2

For k = 2,

= 1- (1/k2)

= 1- (1/(2)2

= 1- ¼

= ¾

at least ¾ or 75% of all values lie within 2 standard deviations of the mean.

Therefore 75% of the eruptions lasted between 1.77 and 4.93 minutes.

Answer:

Step-by-step explanation:

If there were 8 glasses of juice, and 350 ml was poured into each glass, then the total amount of juice poured into the glasses would be 8 x 350 = 2800 ml.

After pouring this much juice, John was still left with 200 ml juice in the jar.

Therefore, the capacity of the jar would be the total amount of juice poured into the glasses plus the amount remaining in the jar, which is 2800 ml + 200 ml = 3000 ml.

To convert this volume to liters, we can divide by 1000. Therefore, the capacity of the jar in liters would be 3000 ml / 1000 = 3 liters.

So, the capacity of the jar is 3 liters.

The transform ,D2Y(s) + 4DY(s) + 40Y(s) = (D+2)X(s) Therefore, the zero-input response of the system y0(t) is given asy0(t) = (e -2t) - 2(cos6t + sin6t) + 6/5

Given that, LTIC system described by the complex-root system is given below.(D2+4D+40)y(t)=(D+2)x(t)

The zero-input response of the response for an LTIC system is given by the initial conditions. The initial condition for the given system is given below.y0(0)=2 and y˙0(0)=16.78.

Using the Laplace transform method, find the transfer function of the given system .

1: Finding the Laplace Transform for the given system(D2+4D+40)y(t)=(D+2)x(t). First, we need to take the Laplace transform of both sides of the given equation. We know that the Laplace transform of y(t) and x(t) are Y(s) and X(s) respectively. Therefore, we get,D2Y(s) + 4DY(s) + 40Y(s) = (D+2)X(s)

2: Solving for the Transfer Function. We know that transfer function is H(s)=Y(s)/X(s). Therefore, we getH(s)= (D+2)/(D2+4D+40)Taking the Laplace inverse of H(s) gives the zero-input response of the given system y0(t).

3: Finding the Zero-Input Response of the given system. We need to find the partial fraction of the transfer function. For that, solve the following equation.D2+4D+40 = 0. Using the quadratic formula, we get,D = -2 ± 6iTherefore, we get the partial fraction of the transfer function as, H(s)=1/(D+2) - 2/D + 3/5 + (3/5s)

Therefore, the zero-input response of the system y0(t) is given asy0(t) = (e -2t) - 2(cos6t + sin6t) + 6/5

Step-by-step explanation:

The degenerate conic which is formed when a double cone is sliced through the apex by a plane parallel to the slant edge of the cone is the "parabolic conic".

A double cone is formed by two cones that are stacked one on top of the other with their vertices touching and with a common axis. If the slicing plane is parallel to the base of the double cone, it will produce a circle. If the slicing plane is perpendicular to the axis, it will produce an ellipse.

If the slicing plane is at an angle to the base, it will produce a hyperbola.If the slicing plane is parallel to the slant height, it will form a parabola rather than a conic.

The differentiation of the function is f'(x) = 6x² + 6 - ln(x) + 3eˣ - cos(x)

from the question, we have the following parameters that can be used in our computation:

f(x) = 2x³ + 6x - 1/x + 3eˣ - sin(x)

The derivative of the functions can be calculated using the first principle which states that

if f(x) = axⁿ, then f'(x) = naxⁿ⁻¹

Using the above as a guide, we have the following:

f'(x) = 6x² + 6 - ln(x) + 3eˣ - cos(x)

Hence, the differentiation of the function is f'(x) = 6x² + 6 - ln(x) + 3eˣ - cos(x)

Step-by-step explanation:

a). 'Per ml' cost of the small size = \(\frac{\text{Sale price of small cane}}{\text{Amount of liquid}}\)

                                                       = \(\frac{4.50}{250}\)

                                                       = $0.018

'Per ml' cost of the medium size = \(\frac{\text{Sale price of medium cane}}{\text{Amount of liquid}}\)

                                                        = \(\frac{9.95}{500}\)

                                                        = $0.0199

     'Per ml' cost of the large size = \(\frac{\text{Sale price of large cane}}{\text{Amount of liquid}}\)

                                                      = \(\frac{16.95}{1000}\)

                                                      = $0.01695

Therefore, expression to compare per ml cost of three containers will be,

$0.0199 > $0.018 > $0.01695  

b). Least expensive way to buy the cleaner is to choose the container with least per ml cost.

Cost of 1500 ml cleaner = Cost of 1000 ml cleaner + Cost of 500 ml of cleaner

                                        = Cost of 1000 ml cleaner container + Cost of 'n' containers of 250 ml container

Total cost of 1500 ml = $16.95 + $4.50n

                                    = 16.95 + 2(4.5) [For n = 2]

                                    = $25.95

c). Most expensive way to purchase 1500 ml cleaner is to choose the most expensive cleaners

Cost of 1500 ml cleaner = Cost of 'n' containers of medium size containers

                                        = 9.95(n)

                                        = 9.95(3)

                                        = $29.85

Step-by-step explanation:

The likelihood that a shooter will hit the target at least 13 times is 27.92%.

For such a binomial distribution, the probability density function equals the amount of successes ("x").

P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ

The required number of achievements is five (i.e., x = 13), as we are keen in the development that the objective will be hit exactly five times.

P(X = 13) =  ¹⁵C₁₃. (0.89)¹³ (0.11)²

P(X = 13) = 0.2792

P(X = 13) = 27.92%

Therefore, there is a 27.92% chance that a shooter will hit the target at most 13 times.

The most appropriate measure of central tendency to summarize the distribution of the variable "health" depends on the data's distribution and the presence of outliers. The mean is suitable for normally distributed data without outliers, while the median is preferable for skewed distributions or data with extreme values.

When summarizing the distribution of the variable "health," it is important to consider the nature of the data and the goals of the analysis.

If the data is normally distributed and there are no extreme outliers, the mean is often the most appropriate measure of central tendency. The mean takes into account all values in the data set and provides a balanced representation of the distribution. It is calculated by summing all the values and dividing by the total number of observations. The mean is particularly useful when the data is symmetrically distributed around a central value.

However, if the distribution of the variable "health" is skewed or contains extreme outliers, the median may be a more appropriate measure. The median represents the middle value in the ordered data set. Unlike the mean, the median is not influenced by extreme values and is less affected by skewed distributions. It provides a robust estimate of the central tendency and is useful when the data contains values that significantly deviate from the majority of observations.

Answer:

16.

Step-by-step explanation:

The formula for a triangle is \(\frac{1}{2} * b * h\)

So, we take the triangle we see and but in in the formula.

\(\frac{1}{2} * 2 * 3 = 3.\)

Multiply that by 4, because there are four triangles that size.

\(3 * 4 = 12.\)

Now, we multiply 2 times 2 because that's the surface area for the bottom.

\(2 * 2 = 4.\)

Now, we add the two.

\(12 + 4 = 16.\)

A process of analysing, purifying, manipulating, and modelling data in order to find relevant information, come to conclusions, and enhance decision-making is known as data analytics.

It entails posing queries and providing answers utilising quantitative and statistical methods for explanatory and prescriptive analysis. Descriptive, diagnostic, predictive, and prescriptive analytics are the four basic categories of data analysis.

Diagnostic analytics is used to determine the reason why something occurred, whereas descriptive analytics is used to report what has already occurred.

The use of predictive analytics, on the other hand, enables the prediction of likely future events. Last but not least, prescriptive analytics is employed to decide what steps should be taken in order to accomplish a particular result or goal in light of the knowledge gleaned from descriptive, diagnostic, and predictive analytics.

By using these different types of analytics, individuals will be able to gather and analyze data to better understand trends, identify problems, and make informed decisions.

The given scenario involves rolling a fair standard 6-sided dice 10 times. We need to calculate the probabilities of two events: A, which denotes the event that the sum of all the rolls is at least 59, and B∪C, which denotes the event of getting exactly four 2's or exactly six 3's.

The probability of event A, P(A), can be calculated using combinatorial techniques and the concept of the probability mass function. Since there are 10 rolls and each roll has 6 possible outcomes (numbers 1 to 6), the total number of possible outcomes is 6^10. To find the favorable outcomes for event A, we need to consider the combinations of numbers on the dice that sum up to at least 59. By evaluating these combinations, we can determine the probability of event A occurring.

To calculate the probability of event B∪C, P(B∪C), we need to find the probability of either getting exactly four 2's or exactly six 3's. This can be done by evaluating the favorable outcomes for each event separately and then adding those probabilities together. The probabilities of getting exactly four 2's and exactly six 3's can be calculated using combinatorial techniques and the probability mass function.

In conclusion, to determine the probabilities of events A and B∪C, we need to consider the combinations of dice rolls and their sums, as well as the number of favorable outcomes for each event. The probabilities can be calculated using combinatorial techniques and the concept of the probability mass function.
