In this problem we will derive an expression for λmax. Use the Lasso objective function excluding the bias term i.e, J(w) = ∥Xw

− y∥2 + λ ∥w∥1. We will show that for any λ ≥ 2∥XT y∥[infinity], the estimated weight vector wˆ is entirely zero, where ∥ · ∥[infinity] is the infinity norm (or supremum norm), which is the maximum absolute value of any component of the vector.

-(5n-9)+3n=-2(5n-20)<br> what is n?
11Alexandr11 [23.1K]

Answer:

n=3.875

Step-by-step explanation:

First, we can expand the brackets:

-(5n-9)+3n=-2(5n-20) (given)

-5n+9+3n=-10n+40

-2n+9=-10n+40 (combine like-terms)

8n=31

n=3.875

Hope this helps :)
