There are two pizzas. Conor ate \( 1 / 4 \) of a pizza, Brandon \( 2 / 8 \), Tyler \( 3 / 4 \), and Audrey \( 4 / 8 \). Who ate the most of the two pizzas?

1. Describe the transformations from the parent function \( y=|x| \). \( \begin{array}{ll}\text { a. } y=-3|x| & \text { b. } y=\frac{1}{3}|x+6|\end{array} \)

To reduce laboratory costs, water samples from six public swimming pools are combined for one test for the presence of bacteria. Further testing is done only if the combined sample tests positive. Based on past results, there is a 0.004 probability of finding bacteria in a public swimming area. Find the probability that a combined sample from six public swimming areas will reveal the presence of bacteria. Is the probability low enough so that further testing of the individual samples is rarely necessary? The probability of a positive test result is (Round to three decimal places as needed.)

You add 9.0 g iron to 28.70 mL of water and observe that the volume of iron and water together is 29.84 mL . Calculate the density
