Correlation
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.
Anxiety symptoms and life satisfaction are negatively correlated. As life satisfaction increases the anxiety symptoms decreases.
Thus, a moderate correlation between them can be expressed by a correlation coefficient of -0.5

Answer: x{ 2,-1,0,-3}
Step-by-step explanation:
[x-2] [x+1] x[x+3]
now separate the equation n equate it to 0
[x-2]=0
[x+1]=0
x[x+3]=0
make x subject and solve for x
x= <u>2</u>
x= -1
x=0 and x= -3
