Apair of equations is shown below:

y = 6x − 4
y = 5x − 3

part a: in your own words, explain how you can solve the pair of equations graphically. write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points)

part b: what is the solution to the pair of equations? (4 points)

(co 3) the soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. the company takes readings of every 10th bar off the production line. the reading points are 5.8, 5.9, 4.9, 6.5, 5.0, 4.9, 6.2, 5.1, 5.7, 6.1. is the process in control or out of control and why? it is out of control as two of these data points are more than 2 standard deviations from the mean it is in control as the data points more than 2 standard deviations from the mean are far apart it is out of control as one of these data points is more than 3 standard deviations from the mean it is in control as the values jump above and below the mean
