What technological and social changes occurred between the Paleolithic ('Old Stone Age') to the Neolithic (New Stone Age') period?

Answer: a = 1/(g-2)

Explanation: We must solve the equation

g =  1 + 2a/a

if the equation is as written, then a/a cancels itself, because a/a = 1, and in that case we can not solve the equation for a:

g = 1 + 2a/a = 1 + 2 = 3

if the equation is, instead:

g = (1 + 2a)/a = 1/a + 2

we can solve it for a, wich means isolating a in one side of the equation, i will do it step by step.:

g = 1/a + 2

g - 2 = 1/a

a(g - 2) = 1

a = 1/(g-2)

Answer: Categorization (option A)

Explanation: Categorization is the procedure in which possible causes and organs that can be affected by them are recognized differentiated and understood. Categorization implies that objects are grouped into categories usually for some specific purpose. Categorization is fundamental in prediction and decision making. Now we know what Categorization means and when listing the potential causes of heart diseases the doctor or researcher needs to categorize in order to determine the cause.

The combinations of data types that is not possible is continuous and categorical

What is continuous and categorical data?

Continuous data, like weight, height, or temperature, is frequently measured on a continuous scale and can have any value within a specified range. Contrarily, discrete values that belong to certain categories or groups such as gender, ethnicity, or product types make up categorical data. Continuous data is made up of values that fall anywhere in a given range of numbers. Examples of continuous data include temperature, time, and individual height. These are measurable values that can be found among a range of potential values.

Groups or categories are represented by categorical data, sometimes referred to as qualitative data. There isn't a numerical value attached to it. Examples of categorical data are car type, gender, and educational background.

complete question;

Which of the following combinations of data types is not possible?

- discrete and categorical

- continuous and categorical

- discrete and numeric

- continuous and numeric

- all combinations of data types are possible

The correct answers are:

- limited;

- can be fossil fuels, minerals, or metals;

The nonrenewable resources are still the ones that are used the most globally, and that is by far. The usage of these resources may be economically beneficial for the time being, but it brings in a lot consequences on the long term.

First thing's first, these resources are limited, so eventually they will end, and if a proper solution is not found and exploited by that time, the economies will crumble. They are big polluters, to the air, water, soil, and their usage results in the destruction of the environment, as well as the increasing of the greenhouse effect.

Within a major, students can choose to study a specific area. This is called a specialization. Thus, option B is correct.

Specialization is defined as the process of focusing resources (labor, capital, and land) on producing a small variety of goods. Because not everyone must farm, an excess of food leads to employment specialization. As a result, some people are able to pursue other interests, like metalworking.

People who can devote time to their crafts become skilled at them and make a living from them, which leads to the development of new technologies. Because some individuals were able to opt out of food production due to the surplus food production produced by other communities, specialized professions and related classes began to emerge.

Therefore, Within a major, students can choose to study a specific area. This is called a specialization. Thus, option B is correct.

Dimensional analysis, also known as factor-label method or unit-factor method, is a method used to convert one unit to a different unit.

Dimensional Analysis is a very basic aspect of measurement and has many applications such as in applied physics.

There are seven steps to do dimensional analysis:

1.35 kilometers per second= ? miles per hour

So first we identify the starting factor:

1.35 km/second * 0.621 miles/km = 0.838 miles/sec (the km cancel out)

Next, we need to convert from seconds into hours. There are 60 second in a minute and 60 minutes in an hour, so there are 60*60=3600 second/hour. Thus,

0.838 miles/second * 3600 second/hour = 3019.86 miles/hour.

Answer: overtime

Explanation:  A fulfilling career will have a work schedule that leaves the student time to relax and do other things he needs, like working, playing with his/her band, doing sports, or things like that.

So a fulfilling career will nor require consistent overtime work (sometimes the overtime work may be a good aspect, but the consistency of it is what generates some problems)

The complete sentence is:

"A fulfilling career will have work schedule that does not require consistent overtime work"

There are approximately 8.958 moles of iron atoms in 500.0 g of iron, and this corresponds to about [tex]5.393 \times 10^{24}[/tex] iron atoms.

How to determine how many moles of Fe atoms?

Calculate the moles using the formula:

[tex]\text{Moles} = \frac{\text{Mass}}{\text{Molar Mass}}[/tex]

Substitute the values:

Moles = [tex]\frac{500.0 \, \text{g}}{55.845 \, \text{g/mol}}[/tex]

Moles ≈ 8.958 mol

So, there are approximately 8.958 moles of iron atoms in 500.0 g of iron.

To find the number of iron atoms, use Avogadro's number, [tex]\(6.022 \times 10^{23}\)[/tex] atoms/mol:

Number of atoms = Moles * Avogadro's number

Number of atoms = [tex]8.958 \, \text{mol} \times (6.022 \times 10^{23} \, \text{atoms/mol})[/tex]

Number of atoms ≈ 5.393 [tex]\times 10^{24}[/tex]

Therefore, there are approximately 5.393 [tex]\times 10^{24}[/tex] iron atoms in 500.0 g of iron.

We know that there are 32,000 ounces in 1 ton. Therefore we use this conversion factor in our calculations. So to convert:

8.9 x 10^5 tons * (32,000 ounces / 1 ton) = 2.848 x 10^10 ounces

Writing in 2 significant figures:

2.85 x 10^10 ounces

Answer: 28.48x10^9 ounces.

Explanation:

We know that 1 ton = 32000 ounces.

Now, if we have 8.9x10^5 tons, how many ounces we have?

we know that each ton is equivalent to 32000 (or 3.2x10^4) ounces, so we need to multiply the number of tons by the number of ounces that each ton has:

8.9x10^5* 3.2x10^4 = (8.9*3.2)x(10^5*10^4) = (28.48)x10^(5+4) = 28.48x10^9

So 8.9x10^5 tons are equivalent to 28.48x10^9 ounces.

Dimensional analysis 134 miles = 8490240. We can use a conversion factor of 63,360 inches per mile to convert 134 miles to inches.

The conversion factor of 63360 inches per mile can be used to convert 134 miles to inches.

12 inches/1 foot 5280 times 12 equals 63360

134 miles is equal to 134 63360 inches.

8,490,240 inches equal 134 miles.

We may eliminate the miles unit using dimensional analysis and replace it with inches by setting up the conversion factor as a fraction with miles in the denominator and inches in the numerator.
