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:
Agriculture
Explanation:
You can rule out A and D immediatly because mining is how they obtain minerals from mines like coal and iron while manufacturing is when they make things in a very large scale using multiple forms of machinery (like in factories).
Agriculture is farming crops and other resources while cultivating the soil to make it better in years to come. This means changing the land for whatever farm uses you need.
Urbanization is when more and more people concetrate in a specific area. Another way to think about it is the shift from rural to urban aerasa in specif cases.
The correct option is A. Alpine glaciers include all of the following except an ice cap.
Alpine glaciers originate on tall mountains and flow through valleys. The ice tops cover a lot of ground. Crevasses and bergshrunds are distinguishing characteristics of glaciers because of their movement.
<h3>Why are Alpine glaciers important?</h3>
Massive supplies of drinkable water from glaciers are available in desert conditions. Snowmelt provides fresh water to the people who live in La Paz, Bolivia. Glacial melt, however, supplies the critical water supply when precipitation levels are low.
High mountains all throughout the world are home to Alpine glaciers, also known as Mountain glaciers. It is referred to as a valley glacier when a mountain glacier enlarges and starts to flow down the valley.
Thus, A is the best choice. All of the items below are part of an Alpine Glacier, but not an Ice Cap.

For clients with borderline personality disorder, it is important to use interventions that set clear boundaries.
Relationships are notoriously challenging for persons with borderline personality disorder (BPD), especially with those closest to them. Loved ones may experience feelings of helplessness, abuse, and instability as a result of their erratic mood swings, explosive tempers, persistent abandonment anxieties, and impulsive and illogical actions. People with borderline personality disorder frequently describe their relationships with their partners and families as an emotional roller coaster with no clear end in sight. If you stay in the relationship or the individual makes efforts to obtain treatment, you could feel imprisoned by your loved one's borderline personality disorder symptoms. However, you are more powerful than you realize.
By controlling your own responses, setting clear boundaries, and enhancing communication with your loved one, you may shift the dynamic of the relationship. Although there is no miraculous therapy for borderline personality disorder, many people with the disorder may and do improve, and their relationships can become more secure and fulfilling. In fact, patients who have the most stability and support at home tend to make progress more quickly than those whose relationships are less orderly and safe.
