Take a look at the expression below:

x² + 4x + 3

To complete the square you have to focus on the number before the x or the (x coefficient).

In this case, this number is 4....

Active transport uses energy in the form of ATP hydrolysis to move a molecule against its concentration gradient.

We know that both balls have the same kinetic energy, so we can write E_ka = E_kb We also know that kinetic energy is given by the equation E_k = 1/2 (mv²) and mom...

Binomial:

1. A single trial has only 2 possible outcomes: success or failure

2. A fixed number of trials, n
