MAT 230 Module One Homework

General:

Before origin this homework, be permanent to unravel the textbook sections and the
material in Module One.

Type your discontinuances into this muniment and be permanent to pretence all steps for arriving
at your discontinuance. Just giving a latest enumerate may not accept bountiful trustworthiness.

You may delineation and paste veracious symbols from the assertions of the
questions into your discontinuance. This muniment was created using the Arial Unicode
font.

The Institutional Release Assertion in the progress shell gives details about
SNHU’s use of systems that assimilate learner submissions to a database of

Module One Homework

1) Suppose C = {red, cerulean, innocent, sombre}. For a) and b) beneath, stuff in two computes that
make the assertion gentleman (over than one discontinuance is likely).
a) __red___ ∈ C, past red is in the set C
b) __orange___ ∉ C, past orange-flame-flame cannot be rest in the set C

2) List the components of the set {x | x ∈ ℤ and x2 We entertain to meditate the components that are integers whose balance compute is hither
than 30. First, we silence that 52 is hither than 30 but 62 is greater than 30. Therefore,
the computes in the set are: {-5,-4,-3,-2,-1,0,1,2,3,4,5}
3) Meditate U = {2, 5, cerulean, apple, $}, A={2, cerulean, $}, and B={5, $}. Complete parts
a) and b) beneath.
a) Is A ⊆ U? Explain why or why not.
Yes, consequently all of the components in A, (2, cerulean and $) are all in U.
b) Is B ⊆ A? Explain why or why not.
No consequently one component of B, 5, is not in A.

4) Meditate the subjoined sets U, A, B, and C.
U = {mathematics, fact, marketing, geography, psychology, English, finance,
statistics, sociology}
A = {marketing, geography, English, statistics}
B = {mathematics, geography, psychology, English}
C = {mathematics, marketing, geography, psychology, sociology}
Compute each of the subjoined:
a) A∪C= {marketing, geography, English, statistics, mathematics, psychology,
sociology}
These are all the components in A and all the components in C (elements in A or C).

Module One Homework

b) C∩B= {mathematics, geography, psychology}
These are the components that are in BOTH C and B.
̅̅̅̅̅̅̅̅̅
c) A
∩ B = {mathematics, fact, marketing, psychology, finance, statistics,
sociology}
We understand that A ∩ B={geography, English} these are the components that are in
BOTH A and B. The supply of tho...
