Answer with Explanation:
Keep in mind these trigonometric Identity:
1. Cos²x - Sin² x= Cos 2 x
2. Cos 2 x = 2 Cos²x-1
3. Cos 2 x = 1 - 2 Sin²x
Now, Coming to the Problem
1 + Cos (18 x)
= 1 + Cos (2 × 9 x)
= 2 Cos ² (9 x)→→→ Cos (2 × 9 x)= 2 Cos² (9 x) - 1

If there is any pattern in a residual plot, that is a sign that regression is appropriate. false; for regression
Regression is a statistical technique used in finance, investment, and other fields to compare a dependent variable (usually denoted by Y) with a set of other variables (known as independent variables). attempts to determine the strength and characteristics of the relationship between
Example: Age and height can be described by a linear regression model. A person's height increases with age, so there is a linear relationship. Regression models are often used as statistical evidence for claims about everyday facts.
