The required surface area of a rectangular container is 588cm² using a volume of 1,372 cm³.
What is the surface area?The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
In comparison to the definition of arc length for one-dimensional curves or the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is equal to the sum of the areas of its faces, the mathematical definition of surface area in the presence of curved surfaces is significantly more complex.
The surface area of smooth surfaces, such as spheres, is determined using their representation as parametric surfaces.
Partial derivatives and double integration are used in this definition of surface area, which is based on infinitesimal calculus techniques.
So, we have the volume:
1,372 cm³
Then, h = 1372/s².
Now, calculate as follows:
4 s 1372/s^2 + s^2 = area
5488/s + s^2 = area
s^2 + 5488 (s^-1) = area
2s - 5488 s^-2 = 0
5488 s^-2 = 2s
5488 = 2 s^3
2744 = s^3
s = 14
s * h * s = 1372
Then, we will have: h = 7
Surface area = 14*14+4*7*14 = 196+4*7*14 = 588 cm²
Therefore, the required surface area of a rectangular container is 588cm² using a volume of 1,372 cm³.

Find the coordinates of X' with X(6,5) for a dilation centered at the origin with a scale factor of -2
On dilating the point X(6,5) with scale factor of -2, the value is obtained as X(-12,-10).
What is dilation?
Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. The initial shape should be stretched or contracted during a dilatation.
The coordinate point for X is given as X(6,5).
The dilation is centered at the origin (0,0).
The dilation scale factor is given as -2.
To find the value of X' use the formula -
X(a,b) → X[(a×(-2)) , (b×(-2))]→ X'
Substitute the values in expression -
X(6,5) → X[(6×(-2)) , (5×(-2))]
X(6,5) → X'(-12,-10)
Therefore, the coordinate point is X'(-12,-10).

The given statement: The standard deviation is a resistant measure of spread is true.
Standard deviation is the measure of how spread out numbers are. It is a measure that is used to quantify the amount of variation or dispersion of a set of data values.
The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability. When data points are closely spaced from the mean, there is a little variation, and when they are far spaced from the mean, there is a large variation. The standard deviation determines how much the data deviate from the mean.
When outliers are included, resistant statistics don't change (or vary very little). Resistance does not imply that anything is immobile; that would be "immovable." It implies that your results could fluctuate a bit, but not much.

. in a warehouse of parts for a large mill, the request happens as poisson process and the average time between requests for parts is about 10 minutes. how can one compute the probabilities of following events using the perspective of: i) poisson distribution and ii) gamma distribution? (no need to evaluate the final number) (a) find the probability that in an hour there will be at least 10 requests for parts. (b) find the probability that the 10th request in the morning requires at least 2 hours of waiting time.
The probability that in an hour there will be at least 10 requests for parts is P(X ≥ 10) = 1 - P(X < 10) = 1 - (Σ P(X = k) for k = 0 to 9) . The probability that the 10th request in the morning requires at least 2 hours of waiting time is P(time until the 10th request ≥ 2 hours) = 1 - P(time until the 10th request < 2 hours) .
i) Poisson Distribution: The Poisson distribution can be used to model the number of requests for parts in a given time period, assuming that the average rate of requests is constant. The Poisson distribution with parameter λ is given by the following formula:
P(k requests in a time period) = (e^-λ * λ^k) / k! , where k is the number of requests, e is the mathematical constant approximately equal to 2.71828, and λ is the average rate of requests.
a) Using Poisson distribution, the probability that in an hour there will be at least 10 requests for parts is given by:
P(X ≥ 10) = 1 - P(X < 10) = 1 - (Σ P(X = k) for k = 0 to 9)
b) To find the probability that the 10th request in the morning requires at least 2 hours of waiting time, we need to find the distribution of the time between requests. Since the requests are modeled as a Poisson process, the time between requests is modeled as an exponential distribution with parameter λ.
ii) Gamma Distribution: The gamma distribution is a continuous probability distribution that can be used to model the sum of k independent and identically distributed exponential random variables. In this case, the distribution of the time between requests is exponential, and the sum of 10 independent exponential random variables gives us the distribution of the time until the 10th request.
a) To find the probability that in an hour there will be at least 10 requests for parts using the gamma distribution, we need to first find the distribution of the number of requests in an hour.The sum of 10 independent exponential random variables with rate λ follows a gamma distribution with shape parameter k = 10 and scale parameter 1/λ.
Using the cumulative distribution function of the gamma distribution, the probability that in an hour there will be at least 10 requests for parts is given by:
P(number of requests ≥ 10) = 1 - P(number of requests < 10)
b) Using Gamma distribution, the probability that the 10th request in the morning requires at least 2 hours of waiting time is given by:
P(time until the 10th request ≥ 2 hours) = 1 - P(time until the 10th request < 2 hours) , where the cumulative distribution function of the gamma distribution can be used to calculate the probability.

A contractor hired 18 workers to complete the construction of a road in 60 days. How many more workers should he hire to complete the construction work 15 days earlier?
Using proportions, if a contractor hired 18 workers to complete the construction of a road in 60 days, to complete the construction work 15 days earlier, the additional workers he should hire is 6.
How is the number of workers determined?We can use proportions to determine the number of workers needed to complete the work 15 days earlier, which is in 45 days.
Proportions are ratios equated to one another.
The number of workers needed to complete a road construction in 60 days = 18
If the contractor wants to complete the work 15 days earlier, he must complete it in 45 days (60 - 15).
The number of workers needed to complete the construction in 1 day = 1,080 (60 x 18)
The number of workers needed to complete the construction in 45 days = 24 (1,080/45)
The difference between completing the work in 60 days and 45 days = 6 workers (24 - 18).
Thus, proportionately, it will take 6 additional workers to complete the construction work 15 days earlier.

Find the volume of the solid obtained by rotating the region bounded by the curves y=x2, x=5, and y=0about the x-axis
Answer:
Step-by-step explanation:
The volume of a solid obtained by rotating a two-dimensional region about an axis can be found using the method of cylindrical shells.
The region in question is bounded by the parabolic curve y = x^2, the vertical line x = 5, and the x-axis. We can find the volume of the solid obtained by rotating this region about the x-axis by adding up the volumes of an infinite number of infinitely thin cylindrical shells with radius equal to the distance from the axis to the boundary of the region at each y-value.
The formula for the volume of a cylindrical shell is given by V = 2 * pi * y * dV, where y is the distance from the x-axis to the boundary of the region at each y-value, and dV is the incremental volume at that y-value.
To find the volume, we need to find the incremental volume dV, and integrate the cylindrical shell formula over the region bounded by y = x^2 and x = 5. The incremental volume is given by dV = pi * (R^2 - r^2)dy, where R is the outer radius, r is the inner radius, and dy is the incremental change in y.
In this case, the outer radius R is equal to the value of x = 5 when y = x^2, and the inner radius is equal to zero. Thus, the incremental volume is given by: dV = pi * (5^2 - 0^2)dy = 25 * pi * dy.
The bounds of the integration are from 0 to 5^2 = 25. Integrating the cylindrical shell formula over this range, we find that the volume of the solid obtained by rotating the region bounded by y = x^2, x = 5, and y = 0 about the x-axis is:
V = 2 * pi * integral from 0 to 25 of (y * 25 * pi)dy = 2 * pi * (25^2 * 25 / 2) = 15625 * pi cubic units.
So, the volume of the solid is approximately 49,093 cubic units.
