A student turned in the following protocol to determine the effect of pH on the rate of emergence of ocean dwelling water bears from their capsules. The directions that were given were to provide a procedure detailed enough that could be used by any student in the class. Students were told that the pH of seawater ranges from 7.5-8.4. There are several problems with this protocol. List each problem then explain how you would change the protocol to solve the problem.

Protocol: One diapausing marine animal was placed in a cup of tap water and the water was stirred until the animal fully emerged from the capsule. The time it took for the animal to emerge was recorded. The experiment was repeated with tap water at different pH’s.

Does anyone know how to find if a certain String is available in an ArrayList?

I was asked by my instructor to make a certain program about Student Record

In the area where I need to add some student in the ArrayList it won't add if there is the same name in the ArrayList

at first I used the equals method and contains method but later I found it was prohibited to use such method.

Is there a way to find if a String is Available in the ArrayList without using the method

Please check on else if(response==2)

Consider that oil can have 10 levels of quality v. Assume that there are the 10 oil producers that produce at each level and can produce the same amount of oil. The cost of producing oil at level v is 2 3 v. Also assume that oils are sold at the international markets and buyers cannot examine the oil quality directly. Assume that there are a lot of consumers, and that their willingness to pay for oil of quality v is v. i.e., if the consumers knew which type of oil they buy, they were willing to pay $v for it. As consumers cannot tell the difference, when buying, between the different quality of oil, they are willing to pay for the average quality oil. For example, if there were only producers of oil at quality 4 and 6 in the market, then the price the consumers were willing to pay is 0.5 × 4 + 0.5 × 6 = 5.

Which producers would be willing to sell in that price?

Let V be the set of all ordered triples of real numbers. For u = (u1, u2, u3) and v = (v1, v2, v3), we define the following operations of addition and scalar multiplication on V :

u + v = (u1 + v1, u2 + v2 − 1, u3 + v3 − 2) and ku = (ku1, ku2, ku3).

For example, if u = (1, 0, 3), v = (2, 1, 1), and k = 2 then

u + v = (1 + 2, 0 + 1 − 1, 3 + 1 − 2) = (3, 0, 2) and 2u = (2 · 1, 2 · 0, 2 · 3) = (2, 0, 6).

Complete the following:

(a) Calculate (1, 1, 1) + (2, 2, 2).

(b) Show that (0, 0, 0) 6= 0.

(c) What is 0?

(d) State a vector space axiom that fails to hold. Give an example to justify your claim.

What is the probability a non-evening student does not live on campus?

Need this program Using Classes , Objects, Save to file, and Printbill Simple python assignment

Write a menu-driven program for Food Court. (You need to use functions!) Display the food menu to a user (Just show the 5 options' names and prices - No need to show the Combos or the details!) Ask the user what he/she wants and how many of it. (Check the user inputs) AND Use strip() function to strip your inputs. Keep asking the user until he/she chooses the end order option. (You can pass quantity1, quantity2, quantity3, quantity4 & quantity5 to save the quantities of the orders) Calculate the price. Ask the user whether he/she is a student or a staff. There is no tax for students and 9% tax for staffs. Add the tax price to the total price. Tax Cupertino 9.000% Santa Clara Display the bill to the user. The bill includes: The food items The quantities The cost of them The total before tax Tax amount Total price after tax You can have your own design but you need to have a main function and get started from the main function. For example: def main(): displayMenu() . . displayBill(..) main() or if __name__ == "__main__": main() The name of functions also up to your design but they should show what the functions do. Only display 2 decimal points when displaying all the numbers. Put at least two outputs (results after you run your code) at the end of your code as a multi-line comment. Don't forget to put your name and a short description of your code on the top on your code. Don't forget to test your code with Positive and Negative Testing!
