Suppose that the pdf for a random variable X is given by f (x )equals x over 2 for 0 less or equal than x less or equal than 2 and f (x )equals 0 otherwise. What is the probability P (0.5 less or equal than X less or equal than 1 )

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
