Ocean sediment core provides a climate record of the past 70 million years.

1880 is the reliable global record which we can say the climate began. Proxies(climate) helps the scientists to determine the climatic patterns even before starting record-keeping.

Some examples of proxies are sub-fossil pollen, lake and ocean sediments, tree rings, and ice cores. Climatic of the time influenced the growth rate of proxies material. It is from proxies where we can recover quantities of particular isotopes from climatic changes.

The combination of proxies can produce temperature reconstruction which is longer the instrumental temperature.

Ocean sediment cores provide a climate record for the past 70 million years. Ocean sediment cores from the bottom of the ocean work as an event timeline. Every year the ocean sediment was piled above the sediment from the previous year. The deeper the ocean sediment, the older it was.

Suppose an economist tests the theory that when the price of leather increases, fewer pairs of shoes are produced. He observes m

Salsk061 [2.6K]

Answer:

b. cannot test his theory because his observations violate the ceteris paribus assumption

Explanation:

As per the law of supply, when price of an input rises, quantity supplied of a good falls, keeping other factors affecting supply as constant (ceteris paribus).

Leather and Shoes are complimentary goods in the sense that leather serves as an input for the product i.e shoes. So if the price of leather rises, production of shoes would fall, keeping other factors constant.

When the price of an input rises, the quantity supplied falls, keeping other factors affecting supply as constant.

In the given case, the price of inputs has increased and yet the production of shoes has increased owing to an advancement in the technology. Technology is a different determinant of quantity supplied and considered as an other factor affecting supply.

Given the following information about the economy of Pakistan, calculate Pakistan's GDP. Note that the currency of Pakistan is t

oksano4ka [1.4K]

Answer:

Pakistan's GDP = 13.53 trillions of rupees.

Explanation:

GDP is the gross domestic product. It is the value of all the goods and services produced by an economy (a country), in a period, which is normally one year.

The GDP can be calculated with the equation:

GDP = Consumption + Investment + Goverment spending + Net Exports

Where, Net Exports is the value of the exports less the value of the imports.

Thus, the values that you need to sue to calculate the GDP are:

Consumptiion
Investment
Goverment spending
Exports
Import

Identify the values that you need to incorporate in your formula. Here is the selection (all the amounts are in trillions of rupees):

Consumption = individuals consume: 10.40

Investment = businesses invest = 1.35

Government spending = goverment purchases = 2.80

Exports = Pakistan exports = 1.29

Imports: Pakistan imports: 2.31

Those are all. Other items, i.e. foreigners spend (0.60 trillions of rupees) and individuals save (5.00 trillions of rupees), do not count for the GDP.

Compute (in trillions of rupees):

GDP = 10.40 + 1.35 + 2.80 + (1.29 - 2.31) = 13.53

Answer: Pakistan's GDP = 13.53 trillions of rupees.
