Suppose that of the students taking probability classes at a university, 30% are sophomores, 45% are juniors, and 25% are seniors. 67% of sophomores live on campus, 56% of the juniors do, and 45% of the seniors do. What is the probability that a randomly chosen student lives on campus?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
