A rocket ship is launched from rest from a space station. Its destinations 1.0 x 10^11 m away. The ship is programmed to accelerate at 7.4 m/s^2 for 12 hours. After 12 hours, the ship will travel at constant velocity until it comes within 1.0 x 10^10 m of its destination. Then, it will fire its retrorockets to land safely.

At 25 C, you conduct a titration of 15.00 mL of a 0.0400 M AgNO3 solution with a 0.0200 M NaI solution within the following cell:
Saturated Calomel Electrode || Titration Solution | Ag (s)
For the cell as written, what is the voltage after the addition of the following volume of NaI solution? The reduction potential for the saturated calomel electrode is E = 0.241 V. The standard reduction potential for the reaction
Ag+ + e- --> Ag(s)
is E0 = 0.79993 V. The solubility constant of AgI is Ksp = 8.3 x 10^-17.
.600 mL = ______ V
10.30 mL= ______ V
30.00 mL= ______V
38.80 mL= ______V

Some five courses are offered on campus in a semester. The group of students who take at least one of these courses consists of 155 students. There are 80 students registered in each course. For any two among these courses, there are precisely 40 students who take both of them. For any three of these courses, there are precisely 20 students who take all three of them. For any four among these courses, there are precisely 10 students who take every one of these four courses. How many students in this group take every one among the five courses in this memorable semester?

A) A coin is tossed and a die is rolled. Draw the tree diagram to list out every possible outcome for this sequence of events. How many total outcomes are possible?
B) Elementary students are given an ID card that has a picture of their face followed by a 4 digit code. Assuming repetitions are allowed, how many ID cards are possible?
C) Six balls are numbered: 1, 2, 3, 5, 8, and 13. A ball is selected, its number recorded, and replaced. Find the expected value for the numbers that will occur. (when needed, round to 4 decimal places)
D) If three coins are tossed, construct the probability distribution for the number of heads that will occur. Then, find the mean (expected value) for the number of heads that occur.
