Forty-three percent of us teens have heard of a fax machine. you randomly select 12 us teens. find the probability that the number of these selected teens that have heard of a fax machine is exactly six (first answer listed below). find the probability that the number is more than 8 (second answer listed below). 0.784, 0.974 0.200, 0.974 0.784, 0.026 0.200, 0.026

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.
