There are 50 tree frogs in the botanical gardens at t = 0. the population increases exponentially by 20% per year.
(a) write an equation that models the problem

(b) about how many tree frogs will there be when t=3?

(c) about how many years will it take until the tree frog population is 200?

(d) what was the tree frog population at t = -1?

(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
