I have to find the value of the standard normal random variable. P (Z <= Zo) = .7054

The random variable X is related to e2. Find P(X>0.4).

Assume the random variable X is normally​ distributed, with mean μ=42 and standard deviation σ=9. Find the 9th percentile. The 9th percentile is ______                                                                                                                  (Round to two decimal places as needed)

Please see below.
