Short answers
5. What two things must you normally specify in a variable declaration?
You must specify the variable type and an identifier.
int n; // type - int, identifier - n
6. What value is stored in uninitialized variables?
is a variable that is declared but is not set to a definite known value before it is used.
Algorithm workbench
3. Write assignment statements that perform the following operations with the variables a, b, and c.
a. Adds 2 to a and stores the result in b
b. Multiplies b times 4 and stores the result in a
c. Divides a by 3.14 and stores the result in b
d. Subtracts 8 from b and stores the result in a
Assignment statements that perform operations with the variables a, b, and c* (*Actually none of these operations involves the variable c at all... is this an error, or a 'trick answer'?):
b = a + 2
a = b * 4
b = a / 3.14
a = b – 8
4. Assume the variables result, w, x, y, and z are all integers, and that w = 5, x = 4, y = 8, and z = 2. What value will be stored in result in each of the following statements?
a. Set result = x + y
b. Set result = z * 2
c. Set result = y / x
d. Set result = y – z
result = x++ - y;
Answer -4
result = 4 – 8 = -4
result = ++w + y;
Answer
w = w + 1 = 5 + 1 = 6
result = 6 + 8 = 14

Homework Assignment
Completed assignment is due at the start of Session 7 on Tuesday, May 19.
This assignment is to be completed in a group of 2 or 3 students. Submit a hard copy, not an
electronic copy (typed answers are preferred). Show your work clearly and explain your
reasoning in detail. You will not receive a credit if the instructor cannot understand what you
have done because of insufficient explanation.
(Q1-Q2) Teddy Bower the Newsvendor
(To answer these two questions, use the Standard Normal Distribution Function Table; one of
the purposes of these questions is to give you a hands-on experience in using the table, which
you will need to do in the final exam.)
Teddy Bower is an outdoor clothing and accessories chain that purchases a line of parkas at $10
each from its Asian supplier, TeddySports. Teddy Bower forecasts that its demand is normally
distributed with mean of 2,100 and standard deviation of 1,200. Teddy Bower sells these parkas
at $22 each. Unsold parkas have zero salvage value.
1. How many parkas should Teddy Bower buy from TeddySports to maximize expected profit?
2. If Teddy Bower wishes to ensure a 98.5 percent in-stock probability, how many parkas
should it order?

ASSIGNMENT (2015-16)
1. During a socio-economic survey conducted in a rural area, the concerned authorities came to the conclusion that mean level of income in the area was Rs 150 per month with a standard deviation of Rs 20 and that income is approximately normally distributed. The total population of the area was 4000. Compute the number of people who fell into the following categories:
(i) monthly income less than Rs 50
(ii) monthly income greater than Rs 100 but less than or equal to Rs 150.
(iii) monthly income greater than Rs 250.
2. The demand of a product is approximately normally distributed with an average demand of 300 units per month. The probability of demand being less than 280 units is 0.025. What is the probability that demand is more than 315 units?
3. Approximately 30% of the time demand of a product is more than 250 units, and 20% of the time demand is less than 200 units. What is the average demand? What is the standard deviation of demand? (Demand can be assumed to follow a normal distribution) The demand of a product is observed to vary from one quarter to the other.

Week 2 Assignment

09/01/2014
For our Week 2 assignment, in Intermediate Algebra, we were asked to solve the problem number 68 on page 539 of Elementary and Intermediate Algebra. aside from completing the problem, we were also asked to write a two to three page paper while including the five given vocabulary words for the week. Please see the problem below:
Shipping restrictions. The accompanying graph shows all of the possibilities for the number of refrigerators and the number of TVs that will fit into an 18-wheeler.
a)
Write an inequality to describe this region.
b)
Will the truck hold 71 refrigerators and 118 TVs?
c)
Will the truck hold 51 refrigerators and 176 TVs?
Kindly consider the five given vocabulary words:
Solid line
Dashed line
Parallel
Linear inequality
Test point
In order to solve the problem, we need to be aware that the formula to solve any linear equation is y=mx+b. with the said, we can say that we have our y- intercept which is 330. (The ordered pair 0,330 demonstrates that the y coordinate is 330). Since we have our y- intercept, we will now discover what our slope is. The formula to determine any slope of a line is
m=y1- y2
x1-x2
M= 330-0
0-100
After performing division and simplifying, we have found that the slope of our line is -3.
a) Write an inequality to describe this region.
The inequality to...
