Answer:
(d) WEAK NEGATIVE ASSOCIATION.
Step-by-step explanation:
Pearson correlation (r) is defined as a factor which measures the linear dependence between two variables (x and y). It's also known as a parametric correlation.
Here, r = -0.19
Now, as r is NEGATIVE.
⇒ As the value of x increases , value of y decreases.
⇒There is a NEGATIVE ASSOCIATION.
Now as the value of r is between 0 and ( -1). So the factor of variation is very small.
Hence, it is WEAK NEGATIVE ASSOCIATION.

Answer:
The third option
Step-by-step explanation:
Given
(a + 3)(- 2a² + 15a + 6b²)
Each term in the second factor is multiplied by each term in the first factor, that is
a(- 2a² + 15a + 6b²) + 3(- 2a² + 15a + 6b²) ← distribute both parenthesis
= - 2a³ + 15a² + 6ab² - 6a² + 45a + 18b² ← collect like terms
= - 2a³ + 9a² + 45a + 6ab² + 18b² → C
