Step-by-step explanation:
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:
2
Step-by-step explanation:
Given the circle:
To determine the length of the radius, we complete the square.
Step 1: Subtract 4 from both sides
Step 2: Divide the coefficient of x and y by 2, square it and add it to both sides
Step 3: Factorize the Left Hand side and simplify the Right Hand side.
Comparing with the standard form of the equation of a circle
r=2
Therefore, the radius of the circle is 2.
The answer is 749,000
748,722.78 is closer to 749,000 than 748,000. So the answer is 749,000 when rounded to the nearest thousands.
