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.
Answer
The classification is shown below:
Explanation:
The saving refers to the amount i.e above its consumption expenditure let us take an example if an individual salary is $100,000 and its expenditure assumes $50,000 then it saves $50,000 so the $50,000 is the savings. While the investment is the amount that is spent to buy some assets in terms of building, machinery, home, etc.
So the classification is presented below:
a. Kyoko borrows money to build a new lab for her engineering firm. = Investment
b. Rina purchases stock in Nano Speck, a biotech firm. = saving
c. Musashi takes out a mortgage for a new home in Detroit. = investment
d.Jacques purchases a corporate bond issued by a car company. = saving
Answer:
$2,610
Explanation:
Calculation for how much money you must borrow.
Using this formula
Amount to be borrowed =( Purchased shares* Per share price*(Initial margin requirement percentage)
Let plug in the formula
Amount to be borrowed= 150 shares*$60 per shares *(1-0.71)
Amount to be borrowed=$9,000*(0.29)
Amount to be borrowed=$2,610
Therefore how much money you must borrow will be $2,610
Answer: 16%
Explanation:
Interest rate on long term treasury securities is calculated below using following formula:
Interest rate = Real risk-free rate + inflation premium + default risk premium + liquidity premium + maturity risk premium
= 3% + 8% + 2% + 2% + 1%
= 16%
Interest rate on long term treasury securities is 16%.
Answer:
C) policy uncertainty
Explanation:
- Policy uncertainty is the class of economic risks associated with the irregular economic policy of a particular country's government. Policy uncertainty discourages investment and increases the investment risk factor of the economy.
- This can come from the regime's volatile and unpredictable monetary or fiscal policy or unpredictable regulatory framework.
so correct answer is C) policy uncertainty
