- question shown in photo. Clear handwriting would be really appreciated as i have a hard time following the variables in a lot of these answersContinuous variable X is distributed on the interval [b,c] = [24.4, 64.6] according to the density curve shown below. As indicated by the plot, the distribution of X is symmetric. What is the mean of this distribution equal to? If there is not enough information to answer this question, enter 0 below. Otherwise, enter the value of the mean. f(x) b сI do not know how to do normal probality density function

A commuter train arrives punctually at a station every half hour. Each morning, a commuter named John leaves his house and casually strolls to the train station. The time, in minutes, that John waits for the train is a variable with density curve y = 1/30 for 0< x< 30, and y = 0 otherwise. a. Graph the density curve of this variable.b. Show that the area under this density curve to the left of any number x between 0 and 30 equals x/30.
