Suppose that k is a field which is not algebraically closed. a. Show that if I ⊂ k[x1, . . . , xn ] is maximal, then V(I) is either empty or a point in kn . Hint: Examine the proof of Theorem 11. b. Show that there exists a maximal ideal I in k[x1, . . . , xn ] for which V(I) = ∅. Hint: See the previous exercise. c. Conclude that if k is not algebraically closed, there is always a maximal ideal of k[x1, . . . , xn ] which is not of the form <x1 − a1, . . . , xn − an >

Scenario: Pacific Imaging Center is a small imaging center with two analogue film or screen units. As the director of the center, Juanita Hernandez has been asked to determine if the current staffing is correct for her place or should she add another technologist. She currently uses 2 mammography units, 2 technologists, and 1 aide. She has analyzed the current costs and determined the following:

Reimbursement per screen $75 Equipment costs per month ($800 per machine) $1,600 Technologists costs per mammography $20 Technologists aide per mammography $4 Variable cost per mammography $10 Equipment maintenance per month per machine ($350 per machine) $700

A. Solve for monthly volume to break even. B. Solve for monthly volume needed to break even at desired $5,000 per month profit level. C. Solve for volume needed to break even at new reimbursement of $112 per screen and no profit. D. Solve for volume needed to break even with an additional technologist

PROMT: Climate Change Effects on Marine Iguana Mortality

1. Hypothesis: If the water temperature in the Galapagos Islands changed from being hot (around 77 degrees) to cold (under 70 degrees), then the mortality rate of Marine Iguanas will increase.
2. Variables: The independent variable is the temperature of the water that the Marine Iguanas live in. The dependent variable is the mortality rate of the Marine Iguanas. The mortality rate of the Marine Iguanas at the average water temperatures of their habitat.
3. Experimental Treatments: Iguana Group 1 will be water temperatures and marine iguana mortality rates before 1998. Iguana Group 2 will be water temperatures marine iguana mortality rates after 199
4. Prediction: By comparting the average water temperatures with the mortality rates every year before the sudden drop in the iguana population and after a trend will be able to be seen. If the water temperature is truly to blame for the mortality rate increase the water temperature will decrease as the population of Iguanas decreases. The control group is intended to show the average number of Iguanas that die due to other causes.

QUESTION ----->>>>> Write a detailed summary of what is wrong with the proposed study ^^^^^????

Your answer should use scientific vocabulary words and address the following questions.

1. Is the study feasible? Will it actually be possible to conduct the proposed study in a controlled manner that produces meaningful data? If there is more than one variable changing simultaneously, no controls, or no replication, then the study is unlikely to produce meaningful data. If there is no way to monitor an experiment in the environment, or no way to conduct the experiment in a controlled environment, like a laboratory, then the experiment is unlikely feasible
2. Can you tell from the text if the experiment is designed to be conducted by performing treatments, or by analyzing observational data about a species and its habitat
3. Is there a testable hypothesis? Is the study set up so that it will be possible to measure the effects in a quantifiable way? What will be measured? Is there a control group and a treatment group? Or, an independent variable like temperature, and a dependent variable like germination time
4. Could you graph the results of this experiment? If so, how would you do it? A column chart to show treatments and controls? A scatter plot or a line graph to look at how changes in the independent variable affect the dependent variable?

Exercise 3

Step 1:

When you read Storing Data Using Sets, you learned that Python's set type allows us to create mutable collections of unordered distinct items. The items stored in a set must be immutable, so sets can contain values of type int, float or str, but we can't store lists or sets in sets. Tuples are immutable, so we can store tuples in sets. Try this experiment, which creates a set containing the points (1.0, 2.0), (4.0, 6.0) and (10.0, -2.0). What is displayed when points is evaluated? Write the question and the answer in lab11.py using python comments. >>> points = {(1.0, 2.0), (4.0, 6.0), (10.0, -2.0)} >>> points We can also initialize the set this way. Try this experiment. What is displayed when points is evaluated? Write the question and the answer in lab11.py using python comments. >>> point1 = (1.0, 2.0) >>> point2 = (4.0, 6.0) >>> point3 = (10.0, -2.0) >>> points = {point1, point2, point3} >>> points We could instead start with an empty set, and call the add method to initialize it, one point at a time. Try this experiment. What is displayed when points is evaluated? Write the question and the answer in lab11.py using python comments. >>> points = set() >>> points.add(point1) >>> points.add(point2) >>> points.add(point3) >>> points

Step 2:

What happens if we try to insert a point that is already in the set? Try this experiment: >>> points.add(point2) >>> points How many copies of point (4.0, 6.0) are in the set? Write the question and the answer in lab11.py using python comments.

Step 3:

Can individual points in the set be retrieved by specifying an index (position)? Try this experiment. What is displayed when points[0] is evaluated? Write the question and the answer in lab11.py using python comments. >>> points[0]

Step 4:

We can use a for loop to iterate over all the points in the set. What is displayed when this loop is executed? Write the question and the answer in lab11.py using python comments. >>> for point in points: ... print(point) ...
