MA/STAT 170 Fall 2010 Assignments
Homework is due at the beginning of class.
Place the assignment on the table in the
front of class as you come in.
Sometime during the class I will put the papers into my
binder.
After this point I will not accept any more papers.
Some of the assignments
precede
the corresponding lecture.
This is intentional.
When
studying for actuarial exams students often must learn material on their own.
You
should be able to answer the questions solely on the basis of the reading.
#1, For Tuesday 8/31:
Read notes, p.1-6.
Do: p. 12,
# 1, 2 , 4, 14, 41 (See Example 3, p. 3.)

#3, For Tuesday 9/7:
Read Examples 5 and 6 on p. 4.
Also read the material on p. 8 beginning with
formula (7) and ending with formula (8).
Note:
If you multiply both numerator and denominator in formula (7) by -1 you get
(1-x^(n+1))/(1-x)= (x^(n+1)-1)/(x-1)
It is this version of the formula that you use in Example 11.
You let x=1.03 and n=19.
Do:
(60) How much will you have if you deposit
$200 dollars at the end of the year for the
