Consider the traffic flow described by the following diagram. The letters A through D label intersections. The data was obtained by counting the number of vehicles that travelled around the four one-way streets between the hours of 6 am to 10 am, and 2 pm to 6 pm during the mid-week peak traffic hours. The arrows in the diagram indicate the direction of flow of traffic in and out of the network that is measured in terms of number of vehicles per hour (vph). 3a) Write the system of linear equations for each intersection. 3b) Use Gauss-Jordan elimination to solve the system.
Determine whether the scatter diagram indicates that a linear relation may exist between the two variables. If the relation is linear, determine whether it indicates a positive or negative association between the variables. Use this information to answer the following. 40 Explanatory Do the two variables have a linear relationship? O A. The data points do not have a linear relationship because they do not lie mainly in a straight line. O B. The data points have a linear relationship because they lie mainly in a straight line. O C. The data points do not have a linear relationship because they lie mainly in a straight line. O D. The data points have a linear relationship because they do not lie mainly in a straight line. Do the two variables have a positive or a negative association? O A. The two variables have a negative association. O B. The two variables have a positive association. O C.
