1. Investigate the difference between "phase velocity" and "group velocity." Why does an index of refraction of less than 1 (so v>c) not violate relativity, which says no information can move faster than the speed of light?

While an inventory policy includes two decisions, use an example to explain what the two decisions are:

Problem 4 (designed to be used with the NORMDIST tutorial)

The following table represents a plan for a project:

1. Construct the appropriate network diagram.
2. Indicate the critical path.
3. What is the expected completion time for the project?
4. What is the probability the project will:
   take more than 43 days to complete;
   take less than 42 days to complete; and
   take between 37 and 42 days to complete?

Draw the red-black BST that results when you insert letters A through K int order into an initially empty tree, then describe what happens in general when trees are built by insertion of keys in ascending order. What about descending order?

The following CPM network has estimates of the normal time in weeks listed for the activities:

1. Please identify the critical path.
2. What is the length of time to complete the project?
3. Which activities have slack, and how much?
4. Based on the table of normal and crash times and costs, which activities would you shorten to cut two weeks off the expected completion time? Does this change the critical path—if so, what is(are) the new path(s).

Imagine that whenever your boss asks for feedback, she/he defensively argues with anyone who offers criticism, so people have stopped offering feedback. You decide to talk to your boss about this and hope to keep the conversation relaxed and professional. Explain how you would approach the conversation and list some points you would want to make when you discuss this issue.

what are the activities we can use with preschoolers to teach them math espcially in the kitchen?

1. Write the set { x | x ∈ R, x2 = 4 or x
2 = 9} in list form.
2. {x: x is a real number between 1 and 2} is an
a) finite set
b) empty set
c) infinite set
3. Write set {1, 5, 15, 25,…} in set-builder form.

b) {a, {a}}
c) {a, {a}, {a, {a}}}
d) {∅}
e) {∅, {∅}, {∅, {∅}}}
5. Suppose that A is the set of sophomores at your school and B is the set of students in
discrete mathematics at your school. Express the following set in terms of A and B:
"the set of students at your school who either are not sophomores or are not taking discrete
mathematics"
a. A
c ∩ Bc
b. A
c U B
c
c. B-A
d. A-B
6. Let A be the set of students who live within one mile of school and let B be the set of
students who walk to classes. Describe the set B-A.
a. The set of students who walk to classes but live more than 1 mile away from school.
b. The set of students who walk to classes but live within 1 mile away from school.
c. The set of students who walk to classes.
7. What is the power set of the set {1, a, b}?
8. Let S = {∅, ?,{?}}Determine whether each of these is an element of S, a subset of S, neither,
or both.
a) {?}
b) {{?}}
c) ∅
d) { {∅ }, ?}}
8. Determine whether each of these statements is true or false.
a) 0 ∈ ∅
b) ∅ ∈ {0}
c) {0} ⊂ ∅
d) ∅ ⊂ {0}
e) {0} ∈ {0}
f) {0} ⊂ {0}
g) {∅} ⊆ {∅}
9. Let A = {a, b, c}, B = {x, y}, and C = {0, 1}.
Find A × B × C.
10. Find A2
if A = {0, a, 3}.

A construction project is broken down into the following 10 activities:

1. Please draw the network.
2. What is the critical path?
3. How many weeks will it take to complete the project?
4. How much slack does each of the activities have?

QUESTION A: PLEASE DRAW THE SKETCH

QUESTIONS B,C,D: USE AN EXCEL FILE

You are experiencing issues when trying to transfer files between two computers using FTP. What could be the potential cause(s) of the issue? Select all that apply.

Which of the following best describes the function of the TTL/hop limit for IP packages?

Research Basics: Lesson 1 ENGLISH 1021-41 ESSAY FUNDAMENTAL

INSTRUCTIONS:

• Read and watch each web page/video/resource.
• Type a summary of the top takeaways/things you learned from each section/link whether they have a video or not. Each paragraph should have complete sentences and there needs to be at least 4 sentences. Think of it as at least one sentence about each of the four top things you learned from each resource you review.
• So, again, you will type up paragraph for each section/link. Label your paragraphs by each section you are writing about. So, give a heading or label that says: What is Research? Information Cycle, and Planning: Keywords and Search Strings, then add you paragraphs about what you learned in each area. Put these paragraphs all together in ONE WORD DOCUMENT.
• Label it Research Basics: Lesson 1 and submit it all together to the Research Basics: Lesson 1 assignment folder by April 20 at 11:59 pm.

This week you will be looking at these sections/links:

What is Research?

Information Lifecycle

Planning: Keywords and Search Strings - Learn how to identify keywords from a research topic and format them into search strings.

NOTE: This link may have words on the web page AND a video. Make sure to view and summarize/give top 4 take always from all included content (what you see/read)

Use VB.net to create a loop that posts the first 100 prime numbers. Then, write code to confirm the numbers are prime.
