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
![r=\frac{sum(x-xbar)(y-ybar)}{\sqrt{sum(x-xbar)^2sum(y-ybar)^2} }](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bsum%28x-xbar%29%28y-ybar%29%7D%7B%5Csqrt%7Bsum%28x-xbar%29%5E2sum%28y-ybar%29%5E2%7D%20%7D)
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=\frac{-6}{\sqrt{23.2(8)} }](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B-6%7D%7B%5Csqrt%7B23.2%288%29%7D%20%7D)
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:
d. Exponential
Explanation:
Sternberg claims that there are three different types of intelligence:
analytical
creative
practical.
Analytical tasks are clearly defined and have only one possible answer. The practical problem, which arises from a concrete life and can have multiple answers, sets a man up to the task of defining himself.
Creative intelligence is usual for artists. In the school, as in intelligence tests, the analytical type of tasks predominate, the tests are inherently biased according to some types of minds.
Answer:
Emotion-focused copying
Explanation:
A small plane has crashed in your neighborhood and you take a fire extinguisher and blankets to the scene. You then stand back and pray when you realize there is nothing you can do to help. In this situation, praying is an example of emotion-focused coping.
Emotion-focused coping techniques aid you in becoming less emotionally reactive to the stressors you face, or altering the way you experience these situations so they impact you differently.
It also involves trying to reduce the negative emotional responses associated with stress such as embarrassment, fear, anxiety, depression, excitement and frustration. This may be the only realistic option when the source of stress is outside the person’s control, like in the case of this plane crash.
The behavioral and cognitive responses used to deal with stressors are collectively called coping strategies.
Coping strategies are tactics to handle stressful conditions. They are generally of two types:
1. Problem-focused coping
It is aimed at problem-solving to change the stressful condition
2. Emotion-focused coping
This type of coping is different and involves modifying emotions to eliminate the stress gained from the problems. It may include self-applause, disaffection, or ignorance.
Problem-focused coping is usually practiced when one feels that the problem causes can be altered and benefits can be assembled. On the contrary, emotion-focused coping is practiced when one knows that the problem can't be altered and will remain the same. Then one needs to change his emotions towards the cause of the problem.
