- Match the function with its graph (labeled i-vi)
- Suppose that X is a normal random variable with mean 5. If P(X>9)=0.2, approximately what is Var(X)?
- Find a vector $A$ with representation given by the directed line segment $AB$. Draw $AB$ and the equivalent representation starting from the origin $A(4, 0, -2), B(4, 2 ,1)$.
- Consider the function below. C(x) = x^{1/5}(x + 6). (If an answer does not exist, enter DNE).
- If X is an exponential random variable parameter, λ = 1 , compute the probability density function of the random variable Y defined by Y = logX.
