Sam is observing the velocity of a car at different times. after three hours, the velocity of the car is 51 km/h. after five hours, the velocity of the car is 59 km/h.

part a: write an equation in two variables in the standard form that can be used to describe the velocity of the car at different times. show your work and define the variables used.

part b: how can you graph the equation obtained in part a for the first six hours?

(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
