Suppose a normally distributed random variable x has a mean of 100 and P(x < 90) = 0.40. What is the probability that x is between 90 and 110? Ie. What is P(90 < x < 110)?

A) find the derivative of the inverse to f(x) = 3x + sint at x 6. b) (cale) find the derivative of the inverse to f(x)+3sin at x 6. if x +2y -34, ind he behaviar of the cure at 4,.3), c) a. increasing, concave up d. decreasing, concave down b. increasing, concave down e. decreasing, inflection point c. decreasing, concave up
