for one roll of die, let a be the event "even" and let b be the event "4,6" find the probability p(a)

What is the ratio if counted 14 robins out of 150

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.

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
