Which of the following is a linear function? an xy coordinate plane is drawn. a parabolic curve that opens to the right is drawn. the vertex of the curve is on the axis. an xy coordinate plane is drawn. an ellipse is drawn on the axis and partially cutting the y-axis. an xy coordinate plane is drawn. a straight line going to left of the origin from the third quadrant to the first quadrant is drawn. an xy coordinate plane is drawn. a straight line starts from the origin and slants down to a certain point in the first quadrant, then is horizontal, and then slants down. all the line segments are straight lines in the first quadrant.

(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
