Scientists are closely monitoring caribou populations to examine the effect of global climate change on
habitat. The maximum population size for a herd of caribou based on the amount of habitat was 500,000. A
herd of caribou currently has a population size of 198,000 caribou as a result of habitat loss. Which of the
following methods should be used to determine the percent change between the maximum population and
the current population for this herd of caribou?

Answers

Answer 1

Answer: (198,000 caribou - 500,000 caribou) / 500,000 x 100

Explanation: makes sense for the math

Answer 2

The percentage difference allows testing the hypothesis. The decrease of 60.4% of the herd is due to the decrease of the habitat.

To test the scientists' hypothesis between the size of the caribou population and the size of the habitat, they must use a statistical method.

The percentage difference is a method that shows the difference between the current values ​​and some reference ones, it allows knowing the magnitude of the change between the two values, its expression is

            D% =[tex]\frac{measured \ value - reference \ value }{reference \ value } \ 100%[/tex]

Let's calculate

              D% = [tex]\frac{198000 - 500000 }{ 500000}[/tex]198000 - 500000/500000 100

              D% = -60.4%

The negative sign indicates decrease.

Therefore, the percentage difference allows the hypothesis to be tested. The decrease of 60.4% of the caribu is due to the decrease of the habitat.

as expressed in the excerpt?
The United States should never engage in foreign commerce.
The United States should increase domestic manufacturing to promote prosperity.
The farmers of the United States should switch to manufacturing jobs.
The sections of the United States should retain separate regional economies.

Answers

Answer:

The United States should increase domestic manufacturing to promote prosperity.

Explanation:

Excerpt:

“The creation of a home market is not only necessary to procure for our agriculture a just reward of its labors, but it is indispensable to obtain a supply of our necessary wants. . . . Suppose no actual abandonment of farming, but, what is most likely, a gradual and imperceptible employment of population in the business of manufacturing, instead of being compelled to resort to agriculture. . . . Is any part of our common country likely to be injured by a transfer of the theatre of [manufacturing] for our own consumption from Europe to America?

“. . . Suppose it were even true that Great Britain had abolished all restrictions upon trade, and allowed the freest introduction of the [products] of foreign labor, would that prove it unwise for us to adopt the protecting system? The object of protection is the establishment and perfection of the [manufacturing] arts. In England it, has accomplished its purpose, fulfilled its end. . . . The adoption of the restrictive system, on the part of the United States, by excluding the [products] of foreign labor, would extend the [purchasing] of American [products], unable, in the infancy and unprotected state of the arts, to sustain a competition with foreign fabrics. Let our arts breathe under the shade of protection; let them be perfected as they are in England, and [then] we shall be ready . . . to put aside protection, and enter upon the freest exchanges.”

Henry Clay, speaker of the House of Representatives, speech in Congress, 1824

      This "System" was made up of three interdependent components: a tariff to support and protect American industry; a national bank to promote trade; and government funding for infrastructure projects like roads, canals, and other "internal improvements" to create viable markets for agricultural products.

What is the short definition of the American system?

       The federal government's strategy for advancing industry in the United States through the implementation of a high protective tariff and the development of internal improvements.

      The American system under Henry Clay established a protective tariff, rechartered the national bank, and supported the growth of the country's transportation infrastructure. This system benefits the north more than the south because the protective tariffs shielded US industry from British competition.

     Which definition best encapsulates Henry Clay's American System? In order to help those in the North, taxes were imposed on goods from the South.

       In a speech he gave in 1824, Clay used the phrase "American System" for the first time. It was a government policy that was founded on the market economy. Specific goods would be produced in some parts of the nation and sold to others.
