Population size can be estimated using the formula
a. (CBR + immigration) + (CDR + emmigration)
b. (CBR + immigration) - (CDR-emmigration)
c. (CBR + immigration) + (CDR - emmigration)
d. (CBR - immigration) + (CDR + emmigration)
e. (CBR + immigration) - (CDR + emmigration)
The formula to estimate population size that accounts for births, deaths, immigration, and emigration is (CBR + immigration) - (CDR + emmigration), which combines natural increase and net migration to calculate population change.
Explanation:The correct formula to estimate population size is e. (CBR + immigration) - (CDR + emmigration). This formula considers both natural increase, which is the result of births minus deaths, and net migration, which is the result of immigration minus emigration. Population change is then calculated by factoring in these elements, allowing for a new population estimate when added to the previous year's population count.
Demographic studies use this formula to understand population dynamics and to assess the potential growth or decline of a population over time. Factors such as birth rates, death rates, and migration patterns are crucial variables considered within this equation when determining changes in population size.
What affect did the California gold rush have on the economy in 1849?
Answer:
In 1849, the California Gold Rush results in a flood of immigrants to the West Coast whose demand for lumber triggers economic development in the Pacific Northwest. Lumber from the Columbia River and from Puget Sound is more plentiful and more easily transported by sea to San Francisco than from the Sierra Nevada. As California grows, so will the timber industry and the economy of the Northwest.
Carpenter James W. Marshall (1810-1885) is credited with first discovering gold on the American River in 1848. Word of the find leaked to the world and the following year, tens of thousands of Forty Niners travel to California by ship and overland. Sparsely settled Oregon Territory experienced a temporary drop in population as men left their farms to find gold. Supplying the miners and the growing city of San Francisco quickly became a major industry and ships called at Northwest settlements looking for logs, which the homesteaders could easily cut close to the water.
After the first big influx of miners -- and the return of many to their homes -- San Francisco and California continued build to houses, wharves, railroads, and mines, all of which required lumber. Water- and steam-powered mills sprang up along the inland shores of Oregon and Washington Territories. Loggers felled trees both to sell and to clear land for farms and cities. The lack of laws governing land use at the time made timber essentially free. Lumbering became the leading industry in the Northwest for the rest of the century.
Improvements in technology -- geared locomotives, donkey engines, and sawmill efficiencies -- helped increase production from 160 million board feet in 1879 to one billion board feet 10 years later. Completion of transcontinental railroad lines in the 1880s and 1890s opened the rest of the country as a market for Northwest forest products.

In the third sentence of the first paragraph, the narrator’s description of Mrs. De Ropp as “those three-fifths of the world that are necessary and disagreeable and real” suggests that Mrs. De Ropp is a strict person who fails to appreciate Conradin’s creative spirit
Explanation:According to Sredni Vashtar (Chronicles of Clovis) it is stated about the story of Clovis:
Conradin was ten years old, and the doctor had pronounced his professional opinion that the boy would not live another five years. The doctor was silky and effete, and counted for little, but his opinion was endorsed by Mrs. De Ropp, who counted for nearly everything. Mrs. De Ropp was Conradin's cousin and guardian, and in his eyes she represented those three-fifths of the world that are necessary and disagreeable and real; the other two-fifths, in perpetual antagonism to the foregoing, were summed up in himself and his imagination. One of these days Conradin supposed he would succumb to the mastering pressure of wearisome necessary things---such as illnesses and coddling restrictions and drawn-out dulness. Without his imagination, which was rampant under the spur of loneliness, he would have succumbed long ago.

Describe which type of motivation you are most likely to respond to and utilize. Explain your answer.
Answer:
According to Incentive theories there are two types of motivation - extrinsic and intrinsic. If you are driven by rewards in the form of outside objects like money, you would respond and utilize extrinsic motivation. If you are on the contrary, driven by internal rewards, like experience or joy from the process, you are likely to respond and utilize intrinsic motivation.
Explanation:
For example, you are attracted mostly by incentives or rewards (extrinsic motivation), not so much the process or journey that gets them there.
Let’s say you want to get good grades at school not because you will get smarter and become fulfilled in life, but solely because you know that presenting good grades to your parents will get you extra rewards - PS5 or more pocket money.
Types of motivation that you can respond to and utilize are intrinsic or extrinsic motivation.
There are two types of motivation:
Intrinsic Motivation: This has to do with internal forces and self-perception that propels one to stir and maintain a certain behavior. This comes from within you rather than external forces. An example of intrinsic motivation is when you participate in sports activities because you enjoy it.Extrinsic Motivation: This usually stems from the external environment.. As a result of what rewards one seeks to get, one might engage in a particular act. For example, if you know you would e rewarded with cash if you pass your exams, you would strive hard as possible to get good grades because of the reward.Therefore, extrinsic and intrinsic motivations are the two types of motivation you can respond to and utilize.

what is the difference between banding and mineral alignment
The crucial difference between banding and mineral alignment in metamorphic rocks is that banding refers to the segregation of minerals into distinct layers under high pressure and temperature, leading to a layered appearance, whereas mineral alignment describes the reorientation of mineral grains in parallel due to directional pressure, forming a foliated texture.
Explanation:The question, "what is the difference between banding and mineral alignment?" focuses on two geological processes that are part of rock formation. Both concepts are fundamental in the study of metamorphic rocks, which are rocks that have been transformed by pressure, heat, and chemical processes deep within the Earth.
Banding refers to the layered appearance of some metamorphic rocks. This texture is formed under high temperature and pressure conditions that cause minerals to recrystallize and segregate into layers or bands of different colors and compositions. Slate and gneiss are classic examples of metamorphic rocks exhibiting banding. Banding results from the differential movement and recrystallization of minerals during the metamorphism process, creating a striped or banded appearance.
Mineral alignment, on the other hand, refers to the parallel orientation of mineral grains within a rock. This alignment occurs because some minerals are subject to directional pressure that causes them to reorient in the direction of the stress. The process of mineral alignment contributes to the foliated texture seen in many metamorphic rocks, such as schist. This texture results when minerals like mica or chlorite are subjected to pressure and align in a way that reflects the direction of the external force.
In summary, the primary difference between banding and mineral alignment lies in the way these textures are formed and appear in metamorphic rocks. Banding involves the segregation of minerals into distinct layers, while mineral alignment involves the reorientation of minerals in parallel lines due to directional pressure.
Explain how and why states in Africa developed and changed over time
African states developed and changed over time due to factors like agriculture, trade, and European colonization which disrupted societies and established boundaries. The Berlin Conference further divided the continent, impacting its geopolitical structure.
Explanation:States in Africa developed and changed over time due to a variety of factors, including intensive agriculture, extensive trade networks, and the influences of European colonization. Prior to colonization, Africa featured a diversity of societies, ranging from small village-based structures to large, complex kingdoms such as the Asante and Zulu. These kingdoms had characteristics similar to modern nation-states, including centralized administrations, legal systems, and multiethnic populations.
The transatlantic slave trade and European colonization significantly disrupted African societies, leading to the depopulation and the breakdown of existing social, political, and economic structures. This history has contributed to the ongoing challenges faced by postcolonial African states.
Furthermore, the Berlin Conference played a pivotal role in the division of African territories among European powers, paying little regard to the established sociopolitical boundaries, which has had lasting impacts on the continent's geopolitical landscape.

Support or refute the assertion that
John Brown was a martyr.
Answer:
Based on the death and general historical role of John Brown, it is most reasonable to argue in support of the statement that John Brown was a martyr.
Explanation:
As one of the first white abolitionists (people who advocated for the abolition of slavery in the USA), John Brown was famous for promoting armed insurrection against slavery, while pacifism was more common among other members of the abolitionists movement.
In 1859 he have organised and armed raid on Harpers Ferry. After a two day attack, John Brown and 18 other insurgents were arrested on October 18, 1859. Brown has not received as much of armed support from slaves as he expected and was defeated so quickly because so only initial 18 insurgents were fighting by his side.
Meanwhile, his subsequent 42-day imprisonment, execution and consistent ideology gained John Brown strong martyr position in the American history. He ultimately became a textbook character. For example, the marching song ‘John Brown’s Body’ became the basis for ‘The Battle Hymn of the Republic’ (1861).
Limit as x approaches 0 of (2e^x-2)/x
Answer:
Explanation:
[tex]\lim_{x \to \ 0} \frac{2e^x-2}{x}[/tex]
So first, we have to plug in zero and see if we can evaluate this limit simply from that.
When we plug in zero we get: (2e^0-2)/0
e^0 is 1 so we have 2-2/0 or 0/0. So we have an indeterminate form type 0/0.
This means we have to apply L'Hospital's Rule.
As a reminder L'Hospitals Rule is [tex]\lim_{x\to \ c} \frac{f'(x)}{g'(x)}[/tex]
Meaning that we take the derivative of the top and bottom function as the approach some value "c". We can do this with a 0/0 indeterminate form.
So:
The derivative of 2e^x - 2 is just 2e^x
and the derivative of x is 1
So we are left with [tex]\lim_{x \to \ 0} 2e^x[/tex]
Plugging in zero we see this gives us 2 as 2(e^0) = 2(1) = 2.
Hence, [tex]\lim_{x \to \ 0} \frac{2e^x-2}{x}[/tex] = 2

D. Positive punishment
E. Continuous reinforcement
Given events are the types of continuous reinforcement. Therefore, option E is correct.
What is Continuous reinforcement?Continuous reinforcement can be described as the repeated reinforcement of a behavior every time it occurs. This involves positive (adding a stimulus) or negative reinforcement, with the goal of encouraging some actions. Continuous reinforcement can be described as one of two foundational kinds of reinforcement schedules.
If you reinforced the behavior every time when your dog rolled over, you were using continuous reinforcement to make him learn the new trick. This is a technique of reinforcing a behavior every time it occurs in order to form an association with the behavior and a specific outcome.
In continuous reinforcement, certain behavior is reinforced every time it takes place. This schedule can be best used while the initial stages of learning to form a strong connection between the behavior and response.
The main purpose of continuous reinforcement is to enhance the occurrence of a specific behavior, whereas punishment will decrease the occurrence of a specific behavior.
