A bank measures the wait time for a random sample of 15 customers during the lunch hour (measured in minutes). A hypothesis test is conducted to see if there is evidence that the average wait time is 5 minutes. What is the decision is made as a result of conducting the test?Waiting Time :4.21, 5.55, 3.02, 5.13, 4.77, 2.34 , 3.54 , 3.20, 4.50, 6.10, 0.38, 5.12, 6.46 , 6.19 , 3.79

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

If the line in the graph is shifted up two units which is the equation of the new line

Solve this system of equations: y=x2-3x + 12 y=-2x+14 4. substitute the values of x, -1 and 2, into either origina equation to solve for the values of y. what are the solutions of the system of equations?
