The wage distribution in Factory A is more erratic. The standard deviation calculates the wage variability or dispersion. The tabular data in this situation show that Factory A has 500 > 400 standard deviation. As a result, there is more variation in the wage distribution in this factory.

By dividing the total number of earnings in a data collection by the number of wages, the mean wage is determined.

It is usually overestimated or underestimated since there are extremes in the data, despite the fact that it is frequently regarded as the “average” wage.

Three mechanisms of evolution are Natural Selection , Genetic Drift and Mutation

How do they work :

1. Natural Selection: This is the process by which organisms that are better adapted to their environment tend to survive and reproduce more successfully than those that are less adapted. This process results in the gradual evolution of the species over time.

2. Genetic Drift: This is the process by which the gene frequencies of a population can change randomly over time due to chance events. This can lead to the emergence of new traits and the disappearance of existing traits within the population.

3. Mutation: This is the process by which new genetic information is added to the gene pool of a population. This can result in the emergence of new traits or the alteration of existing traits.

Answer:The introduction of nutrients such as nitrates and phosphates into water can affect the penetration of light through the water in several ways. These nutrients can stimulate the growth of phytoplankton and other aquatic plants, which can increase the amount of algae and other suspended particles in the water. This can cause the water to become more turbid, or cloudy, reducing the amount of light that is able to pass through it.

Additionally, the increased growth of phytoplankton and other aquatic plants can lead to algal blooms. These blooms can produce pigments and other chemicals that can absorb or scatter light, further reducing the penetration of light through the water. This can create areas of low light or even complete darkness, which can have negative impacts on the health and survival of aquatic plants and animals.

Answer:

Below...

Explanation:

To find the critical points, we need to find where the gradient of f(x,y) is equal to zero.

∇f(x,y) = (-sin x, sin y)

Setting each component of the gradient equal to zero, we get

-sin x = 0 and sin y = 0

This gives us critical points at (nπ, mπ) for any integers n and m.

Next, we need to find the second partial derivatives of f(x,y) at each critical point.

f_xx = -cos x

f_yy = cos y

f_xy = 0

At a critical point (nπ, mπ), we have f_xx = (-1)^n and f_yy = (-1)^m.

If f_xx and f_yy have the same sign, then the critical point is a local extremum. If they have opposite signs, then the critical point is a saddle point.

Thus, we have the following cases:

(nπ, mπ) is a local minimum if n and m are both even.

(nπ, mπ) is a local maximum if n and m are both odd.

(nπ, mπ) is a saddle point if n and m have different parities.

To find the level curves for z = 0, we set f(x,y) = 0:

cos y - cos x = 0

cos y = cos x

y = ±x + 2πk, where k is an integer

Thus, the level curves for z = 0 are given by the planes y = x + 2πk and y = -x + 2πk for integer values of k.

A 0.81 is 81% likelihood that neither consumer will be chosen to get a coupon is discovered using the binomial distribution.

Each buyer can either receive the coupon or they don't; there are only two conceivable outcomes. The binomial distribution is employed to answer this question since every customer has an equal chance of receiving the coupon.

Explanation:

These are the conditions:

The success rate is expressed as x.

N trials will be conducted.

The likelihood that a trial will be successful is expressed as p.

10% chance of receiving a coupon is there in this issue for each consumer.

the selection of 2 customers

Read , Recite and Review are one of the three Rs in the SQ3R method.

SQ3R is a study technique that was created on the basis of cognitive psychology research that encourages improved reading comprehension (APA, 2020).

Francis P. Robinson, a well-known American educational psychologist, made the SQ3R proposal in his 1946 book Effective study. Robinson is described as a pioneer in the development of postsecondary literacy theory, research, and pedagogy by Stahl and Armstrong (2020) in a very recent article in the journal Reading Literacy.

Robinson is most well-known to SQ3R, despite his enormous and varied contributions to the field of reading and learning.

The supplied normal curve has a standard deviation of 0.34.

What is deviation ?

Deviation is a mathematical and statistical measure of the difference between the measured parameter and another value, frequently the mean of that variable. The deviation's sign indicates the difference's orientation (the deviation is positive when the observed value exceeds the reference value). The size of the difference is indicated by the value's size. A deviation is a mistake where there is a discrepancy between the actual value and the actual value of a quantity of interest (where the true value represents the Expected Value, like the population mean). A deviation is the variance between an estimation of the true value and the observed value.

The part of mathematics that deals with probability is called probability theory. Probability is a concept that can be interpreted in a variety of ways, but probability theory tackles the idea in a rigorous mathematical way by articulating it through a series of axioms. Typically, such axioms define chance in terms of a sample space, which links a collection of outcomes known as the sample space to a measure having values ranging from 0 and 1.
