Consider the following functions. f(x) = x² - 4
g(x) = x-2

What is (f(x))(g(x))?
O (f(x))(g(x)) = x + 2; x = 2

O (f(x))(g(x)) = x + 2; x € all real numbers
O (f(x))(x)) = x3 - 2x2 - 4x + 8; x + 2
O (f(x)/(g(x)) = x3 - 2x2 - 4x + 8; x € all real numbers

Describe in detail how you would construct a 95% confidence interval for a set of 30 data points whose mean is 20 and population standard deviation is 3. be sure to show that you know the formula and how to plug into it. also, clearly state the margin of error.

You decide instead to take the train there. the train will take 135 minutes. convert this into hours and minutes.
