They trained their armies very well so they would be ready for another war like WWII if one happened again.
Answer:
restricting the money supply by adjusting interest rates
Explanation:
As you may already know, inflation is the term used to refer to the exaggerated and continuous increase in the price of all products present on the market in a given country. Inflation can generate a lot of economic and even social damage, for this reason, it is necessary for the government to establish strategies that reduce the level of inflation in the country.
In the short term, the strategies that the government can adopt when inflation is high are to reduce spending, but to increase taxes and raise interest rates. With that, we can say that the government restricts the money supply within the country, limiting spending, but adjusting interest rates so that they get higher. As a result, the demand for products will be less than the supply. The result of this, is a tendency to decrease the price of products.
The Qin dynasty paid for their great building projects by<u> </u><u>Taxing the people</u>
This affected the fall of the Qin Empire because:
- <u>It destroyed the economy and caused a revolt</u>
Some of the building projects that were undertaken by the Qin empire includes:
- The Great Wall of China
- The Lingqu Canal
- The Dujiangyan Irrigation System
- The Zhengguo Canal, etc
These great building projects were mostly financed by collecting levies and taxing the people which was so expensive for the people to continue paying. This eventually led to a revolt of the people against the Qin dynasty.

Answer:
1. Co-variance= -1.2
2. correlation coefficient= -0.4404
3. There is weak negative relationship between x and y.
Explanation:
1.
Co-variance= Cov(x,y)= sum[(x-xbar)(y-ybar)]/n
xbar=sumx/n=32/5=6.4
ybar=sumy/n=35/5=7
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
Cov(x,y)= sum[(x-xbar)(y-ybar)]/n=-6/5=-1.2
Cov(x,y)=-1.2
2.
correlation coefficient=r
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
(x-xbar)² 0.36 2.56 1.96 11.56 6.76
(y-ybar)² 0 4 4 0 0
r=-0.4404
3. Since the value of correlation coefficient is negative and less than 0.5 , so, we can say that there is weak negative relationship between x and y.
