answer:people are racial
and they believe that they are the only race around
Before the Portuguese explored and went to the East, in order to obtain the Asian goods, they had to trade with the Muslims and was more expensive. But, after Vasco de Gama reached India, the Portuguese had a sea route that gave them direct access to Asia which meant no more trading with the Muslim. They could trade with the rest of Europe and sell for cheaper.
A symmetric multiprocessor organization has a number of potential advantages over a uniprocessor organization including performance, availability, incremental growth, and scaling.
A symmetric multiprocessor contains two or more identical processors that share a single main memory. Multiple processors can be separate chips or multiple cores on the same chip. Multiprocessors allow more threads to run simultaneously and certain threads to run faster. It's easy to run multiple threads concurrently.
Threads are simply split between processors. Unfortunately, the average PC user needs only a few threads running at a time. Making a particular thread run faster is much more difficult. Programmers must split existing threads into multiple threads running on each processor.

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.
Answer:
C
Explanation:
wikipedia says: "The Connecticut Compromise (also known as the Great Compromise of 1787 or Sherman Compromise) was an agreement that large and small states reached during the Constitutional Convention of 1787 that in part defined the legislative structure and representation that each state would have under the United States Constitution. It retained the bicameral legislature as proposed by Roger Sherman, along with proportional representation of the states in the lower house or House of Representatives, but required the upper house or Senate to be weighted equally among the states. Each state would have two representatives in the upper house."
