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.
<span>The statement is "False".</span><span>
It actually is referring to the act of Secondary Oppression. </span>Tertiary
oppression is executed by individuals from a
persecuted gather when they look for acknowledgment by supporting the
predominant party's onerous demonstrations. For instance a minority-group member
may oppress kindred group individuals to get support with prevailing group
individuals.
Answer:
Explanation:
its the 2nd one i think. tell me if im wrong
First thing that comes to mind is Russia had a strategic advantage to the Nazis. The Russian military knew the terrain (I believe it was mountainous) and the cold climate helped push back the Nazis. The Nazis actually tried to get into Russia. That was the only country I could think of.
Most countries, I think did not have the military power to stop Hitler/Nazis from invading them.
Hopefully this helps.
