So if x= number of trees, and y= rental applications, the owner wants to see if increasing x will increase y. The correlation coefficient is between -1 and 1. If the number of trees really does have a positive impact on rental applications, the correlation coefficient would be close to 1. If there is absolutely no relationship, the coefficient would be near zero. If planting trees causes a DECLINE in rental applications, the coefficient would be close to -1.
Answer:
2nd option
Step-by-step explanation:
Express the sum of the 2 polynomials by removing the parenthesis , so
5
- 2x³ + x + 4
- 3
+ 2x³ - 5x ← collect like terms
= 9
- 3
- 4x
