Hi,
You just have to change z^25 to z^24 or z^27.
Answer:
A. 5x+6
Step-by-step explanation:
-
(9x-18)+8x
-3x+6+8x (multiply across the -1/3)
5x+6 (combine 8x and -3x)
0....1/4..... 2/4 or 1/2 ..... 3/4..... 1.... 1 1/4.... 1 2/4 or 1 1/2...... 1 3/4..... 2.... and so on and so on
Answer:
There is a strong positive relationship between sales of firewood and cough drops.
Step-by-step explanation:
Correlation Coefficient
- 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.
- Values between 0 and 0.3 tells about a weak positive linear relationship, values between 0.3 and 0.7 shows a moderate positive correlation and a correlation of 0.7 and 1.0 states a strong positive linear relationship.
Thus, a coefficient correlation of 0.85 between weekly sales of firewood and cough drops over a 1-year period suggest that there is a strong positive relationship between sales of firewood and cough drops.
Thus, as the sale of firewood increase there is an increase in the sale of cough drops.
