Put a ceramic mug and a metal pot or dish in the freezer and wait for a half hour...

Now get the shower going as hot as it will go; really steam up the bathroom. Keep the fan off and the bathroom door closed. After the bathroom is good and steamy take the cold items from your freezer into the bathroom. What do you observe in terms of condensation? How does the condensation on the ceramic mug compare with the condensation on the metal pot?

Now try it with the ceramic mug and metal pot starting at room temperature.

Now try it with the ceramic mug and metal pot after they have been heated up in the oven at 300 degrees for a half hour.

I just need to know what *should* happen in an experiment like this. Thank you (:

Hands Insurance Company issued a $90 million, 1-year, zero-coupon note at 8 percent add-on annual interest (paying one coupon at the end of the year). The proceeds were used to fund a $100 million, 2-year commercial loan at 10 percent annual interest. Immediately after these transactions were simultaneously closed, all market interest rates increased 2 percent .

a. What is the true market value of the loan investment and the liability after the change in interest rates?

b. What impact did these changes in market value have on the market value of the equity?

c. What was the duration of the loan investment and the liability at the time of issuance?

d. Use these duration values to calculate the expected change in the value of the loan and the liability for the predicted increase of 2 percent in interest rates.

Assume that an English comprehension test is given to a random sample of 12 students before and after they complete an English course. The tests taken before the course had   x? =105.75 points and s = 4.07 points.  The tests were taken after the course had x? = 113.08 points and s = 3.63 points.

Complete a hypothesis test to determine if the course improved the test score using a significance level ? = 0.05.

1) Calculate the change in pH when 49.0 mL of a 0.780 M solution of NaOH is added to 1.00 L of a solution that is 1.00 M in sodium acetate and 1.00 M in acetic acid.

2) Calculate the pH of 100.0 mL of a buffer that is 0.0650 M NH4Cl and 0.110 M NH3 before and after the addition of 1.00 mL of 6.00 M HNO3.

calculate: pH before and ph After

(a) A toy car1 has a mass of 1.6 kg and is moving with a velocity of 6.0 m/s to the right. It collides with a second car2 (mass 2.4 kg). The cars stick together. After the collision, both cars move with a velocity of 1.5 m/s to the left.

(a) How fast and in what direction was car2 traveling before the collision?
(b) Calculate the total kinetic energy of the system before and after the collision.

Austin Peay State, a university near Nashville, Tennessee, is applying a data-mining approach to higher education. Before students register for classes, a robot looks at their profiles and transcripts and recommends courses in which they are likely to be successful or have higher chances of success. The software takes an approach similar to the ones Netflix, eHarmony, and Amazon use to make their recommendations. It compares a student’s transcripts with those of past students who had similar grades and SAT scores. When a student logs in, the program offers 10 “Course Suggestions for You.” This recommendation is based on the student’s major and other information related to that student. The goal is to steer students toward courses in which they will make better grades. According to Tristan Denley, a former programmer turned math professor turned provost, students who follow the recommendations do substantially better. In the fall of 2011, 45 percent of the classes that students were taking had been on their top 10 recommendations list. This data-mining concept is catching on. Three other Tennessee colleges now use Denley’s software. Institutions outside the state are developing their own versions of the idea.

1. What are the benefits and drawbacks of this approach to course recommendations?
2. Are there any data that should or should not be included in data mining for this purpose? Why or why not?

Different breeding lines of rats ran a maze, then were exposed to an EMP (electro magnetic pulse, such as would occur from a nuclear explosion then ran a similar maze again. The maze running times were compared and the rats were classified into 3 groups. After slower than before, after close to before, and after faster than before. The categories are shown in the table below. Are different broads reacting differently to radiation? Test at the .01 level.
