Answer:
The relationship is proportional.
The relationship is linear.
The equation of the line is y = –3x.
Step-by-step explanation:
The line in the question passes through origin and (4,-12).
The rate of change of the line is

The rate of change of the line or slope of the line is -3
Equation of the line is given by

This means that the relationship is linear.
If we take any value of x then there will be only one value of y this means that the relationship is proportional.
So the following statements are true
The relationship is proportional.
The relationship is linear.
The equation of the line is y = –3x.
Answer:
a) -0.5
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: 4z (to the 2 power) - 13z + 3
Step-by-step explanation:
Complementary angles equal 90 degrees. The ratio is 2:3.
2+3=5
90/5=18
2(18):3(18)
36 degrees, 54 degrees
Answer:69 2/9 - 31 1/9 - (- 12 4/9) =
69 2/9 - 31 1/9 + 12 4/9 =
81 6/9 - 31 1/9 =
50 5/9 or 455/9 or 50.56 <==
