If a denotes some event, what does upper a overbardenote? if p(a)equals0.995,what is the value of p(upper a overbar)? if p(a)equals0.995,is upper a overbarunlikely? what does upper a overbardenote? a. event upper a overbardenotes the complement of event a, meaning that upper a overbarand a share some but not all outcomes. b. events a and upper a overbarshare all outcomes. c. event upper a overbardenotes the complement of event a, meaning that upper a overbarconsists of all outcomes in which event a does not occur. d. event upper a overbaris always unlikely.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
