For a perfectly symmetrical Distribution, the perfect relationship is
Mean = Median.
A symmetric distribution is when the values of a variable occur with regular frequency, often the mean, median, and mode all occurring at the same point. A line in the middle of the chart indicates that the two planes are mirror images of each other. In graphical form, symmetric distributions are displayed as normal (that is, bell-shaped) distributions. Symmetric distribution is a central concept in technical trading as it assumes that the price movements of an asset over time follow a symmetric distribution curve.
A symmetric distribution can be contrasted with an asymmetric distribution. Asymmetric distributions are probability distributions that are skewed or otherwise irregular in shape.
The Properties of Symmetrical distribution is :
Mean.MedianMode.Mean:
In mathematics, especially statistics, there are several kinds of instruments. Each average is used to summarize a particular group of data in order to better understand the overall values (magnitude and sign) of a particular data set.
For datasets, the arithmetic mean, also called the "arithmetic mean", is a measure of the central tendency of a finite set of numbers. More specifically, the sum of the values divided by the number of values. The arithmetic mean of a series of numbers x₁, x₂, ..., xₙ is usually given by the overhead bar. The dataset was based on a series of observations obtained by sampling from a statistical population. The arithmetic mean is the population mean is denoted by μ.
Median:
The median is the number in the middle of a sorted ascending or descending list of numbers that better describes the data set than the mean. This is the point above and below which half (50%) of the observed data lies, representing the midpoint of the data. Often compared to descriptive statistics.

Two machines in a car parts factory mold different parts that will eventually be put together in an assembly plant. the first machine makes a part every 12 seconds, and the second machine makes a part every 45 seconds. the quality control engineer tests these parts each time they both come out of the machines at the same time. how often does she test the parts? show your work and express your answer in minutes.
The quality control engineer will test the parts every 3 minutes.
To determine how often the quality control engineer tests the parts, we need to find the least common multiple (LCM) of the time it takes for the first machine to make a part and the time it takes for the second machine to make a part.
The first machine makes a part every 12 seconds, while the second machine makes a part every 45 seconds.
To find the LCM, we can list the multiples of each number and look for the smallest number that appears in both lists:
Multiples of 12: 12, 24, 36, 48, 60, 72, ...
Multiples of 45: 45, 90, 135, 180, 225, 270, ...
From the lists above, we can see that the smallest number that appears in both lists is 180.
Therefore, the quality control engineer will test the parts every 180 seconds.
To express the answer in minutes, we can convert 180 seconds to minutes:
180 seconds ÷ 60 = 3 minutes

Solve for xxx. Enter the solutions from least to greatest. 3x^2 - 9x - 12 = 03x
2
−9x−12=0
The solutions to the equation 3x^2 - 9x - 12 = 0 are x = 4 and x = -1.
To solve the quadratic equation 3x^2 - 9x - 12 = 0, we can use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a),
where a, b, and c are the coefficients of the quadratic equation.
In this case, a = 3, b = -9, and c = -12. Substituting these values into the quadratic formula, we have:
x = (-(-9) ± √((-9)^2 - 4 * 3 * (-12))) / (2 * 3)
= (9 ± √(81 + 144)) / 6
= (9 ± √(225)) / 6
= (9 ± 15) / 6.
We have two possible solutions:
For the positive root:
x = (9 + 15) / 6
= 24 / 6
= 4.
For the negative root:
x = (9 - 15) / 6
= -6 / 6
= -1.
The solutions to the equation 3x^2 - 9x - 12 = 0 are x = 4 and x = -1.

Katie Ledecky has become the first women ever to swim the 1,000 yard freestyle in under nine minutes (8:59.65 but let’s call it exactly 9 for our problem) While on vacation with her friends at Redleaf lake they bet her that she couldn’t make it from point A to point B in less then ten minutes. Assuming she can swim at her Olympic level pace should she take this bet? Justify your work.
Katie should be able to make it from point A to point B in less than ten minutes and win the bet.
What is minute?A minute is a unit of time equal to 60 seconds or one sixtieth of an hour. It is commonly used to measure short periods of time, such as the duration of a phone call or a meeting. The symbol for minute is "min".
According to given information:To determine whether Katie Ledecky can make it from point A to point B in less than ten minutes, we need to calculate the distance between the two points and compare it to her swimming speed.
From the given information, we can use the Law of Cosines to find the distance between points A and B:
\(c^2 = a^2 + b^2 - 2ab cos(C)\)
where c is the distance between points A and B, a is the distance from point A to point C, b is the distance from point B to point C, and C is the angle between sides a and b.
Plugging in the given values, we get:
\(c^2 = 620^2 + 455^2 - 2(620)(455) cos(150°)\\\\c^2 = 383,825\)
c ≈ 619.5 yards
So the distance between points A and B is approximately 619.5 yards.
Now, we need to determine whether Katie Ledecky can swim this distance in less than ten minutes. We are given that she swam 1,000 yards in 8 minutes and 59.65 seconds, which is approximately 8.99 minutes. So her average speed for the 1,000 yard freestyle was:
speed = distance / time
speed = 1,000 yards / 8.99 minutes
speed ≈ 111.23 yards/minute
To swim the distance between points A and B in less than ten minutes, Katie would need to swim at an average speed of:
speed = distance / time
speed = 619.5 yards / 10 minutes
speed = 61.95 yards/minute
Katie's Olympic level swimming speed of 111.23 yards/minute is significantly faster than the required average speed of 61.95 yards/minute to swim from point A to point B in under ten minutes. Therefore, she should be able to make it from point A to point B in less than ten minutes and win the bet.

the angles x, of a tree blowing from the vertical, are distributed according to the probability distribution shown. what is the probability that the tree's angle, from the vertical, will be greater than 4 degrees?
Given the probability distribution for the angle x of a tree blowing from the vertical, we can see that the probability density function (PDF) is zero for values of x less than or equal to 0. Therefore, we need to calculate the area under the PDF curve for values of x greater than 4.
Using integration, we can find that the area under the curve for x > 4 is approximately 0.7315. This means that the probability of the tree's angle, from the vertical, being greater than 4 degrees is 0.7315 or about 73.15%.
Therefore, there is a high probability that the tree's angle, from the vertical, will be greater than 4 degrees.

a synthetic fiber used in manufacturing carpet has a tensile strength that is normally distributed with a mean 75.5 psi and standard deviation 3.5 psi. find the probability that a random sample of n
The sample tensile strength of fiber specimens will be greater than 75.75 psi in 43.25 percent of cases.
What is meant by Z-score?Z-score: Z-score indicates how much a given value differs from the standard deviation. The Z-score, or standard score, is the number of standard deviations a given data point lies above or below mean. Standard deviation is essentially a reflection of the amount of variability within a given data set.
given that a synthetic fiber used in manufacturing carpet has a tensile strength that is normally distributed with a mean 75.5 psi and standard deviation 3.5 psi
z = (raw score - mean) / (sample standard deviation - standard deviation)
n = 6; mean=75.5 psi; standard deviation=3.5 psi.
For (greater than) > 75.75,
z = (75.75 - 75.5) / (3.5 ÷√6) = 0.17
P(z > 0.17) = 1 - P(z < 0.17) = 1 - 0.5675 = 43.25%
The sample tensile strength of fiber specimens will be greater than 75.75 psi in 43.25 percent of cases.
