A cell phone company charges $20 a month for the base plan. They charge 10 cents for every text, minute, or kilobyte of data use. Write and equation to express your cell phone bill.

O y = .20x - 10
O y = 10x – 20
O y = .10x + 20
O y = 20x + .10

Equation for the calculation double 2 and then add 5

(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
