$7^x+49^{ \frac{x}{2} }=2\cdot \sqrt[5]{343} \\ \\ 7^x+(7^2)^{ \frac{x}{2} }=2\cdot \sqrt[5]{7^3} \\ \\7^x+ 7^x=2\cdot 7^{ \frac{3}{5} } \\\\ 2 \cdot 7^x=2\cdot 7^{ \frac{3}{5} } \ \ \ | \div2 \\ \\ 7^x=7^{ \frac{3}{5} } \\ \\ x= \frac{3}{5}$

Does every triangular matrix have an lu decomposition?.

Annette [7]

Yes. If you're given a lower triangle matrix A, then A = LU if L = A and U = I (the identity matrix). If your matrix is upper triangular, then A = LU with L = I and U = A.

Answer:

The proportion of customers who used coupons within the last 2 years is 0.1089.
