Let X be the random variable for this question. P(X=x) = 1/3 for all x. When X=x, we have that it took x times for us to retrieve the correct key.Thus, we have the infinite sum 1/3 + 22/31/3 + 3*...

firstly, glucose is converted into glucose phosphate and then into glucose biphoshate through phosphorylation. This process turns two molecules of ATP to ADP. This is then split into two molecules (3 carb...

In order to find the stationary points we need to find the first derivative, set it to 0 and solve for x. We can then use this value to find the value for y.y = e^{(3x-x^3)}We know for the derivat...
