I need help with this question

A probability density function of a random variable is given by f(x) = 11 1+ on the interval [16, 25]. Find the expected value, the variance, and the standard VX deviation. ..... The expected value is J ~ R (Round to two decimal places as needed.) al The variance is Var(X) ~ (Round the final answer to two decimal places as needed. Use the expected value rounded to two decimal places. Do not round any other intermediate values.) The standard deviation is o ~ (Round the final answer to two decimal places as needed. Use the expected value and variance rounded to two decimal places. Do not round any other intermediate values.)
