Your 'question form' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.

I did a pratice test and inserted awnsers into the original doc and recived this response

The statements of the test problems did not come through in the text form.

You should type out a brief statement of the test problems so I can compare your solutions to the actual problems.

On the test you will need give a full description of your reasoning on each problem. Just the answer is never sufficient; you always have to explain how you got the answer. All answers on a test must be justified by your reasoning (see also instructions on the test, which state this).

Then I took a second pratice test and rewrote the questions as instructed in first response received and recived this response and no comment on the work.

&#I need to see the questions so I can be sure what your answers mean. Most of the time I can tell, but I'm dealing with information that comes in from over 1000 different files, containing a total of about 10 000 questions. While I'm familiar with the content and sequencing of the questions, having written them all, and know what I'm looking for, different students will answer these questions in different ways and I need to be able to relate your answers to the specific wording of each question. When reviewing my responses you will also need to be able to relate your answers and my comments to the specifics of the original document.

So it will be important for you on future documents to insert your responses into a copy of the original document, according to instructions, without otherwise changing any of the content of the original document. This will ensure you of the best possible feedback on your work. &#

So my question is what do I need to do in the future to successfully submit a pratice test?

As I felt the first was as described in your instructions and the second was as described in the response from the first response, Below are the two documents coppied and pasted from the submission page

Test should be printed using Internet Explorer. If printed from different browser check to be sure test items have not been cut off. If items are cut off then print in Landscape Mode (choose File, Print, click on Properties and check the box next to Landscape, etc.).

• Write on ONE SIDE of paper only

• If a distance student be sure to email instructor after taking the test in order to request results.

Signed by Attendant, with Current Date and Time: ______________________

If picture ID has been matched with student and name as given above, Attendant please sign here: _________

Instructions:

• Test is to be taken without reference to text or outside notes.

• Graphing Calculator is allowed, as is blank paper or testing center paper.

• No time limit but test is to be taken in one sitting.

• Please place completed test in Dave Smith's folder, OR mail to Dave Smith, Science and Engineering, Va. Highlands CC, Abingdon, Va., 24212-0828 OR email copy of document to dsmith@vhcc.edu, OR fax to 276-739-2590. Test must be returned by individual or agency supervising test. Test is not to be returned to student after it has been taken. Student may, if proctor deems it feasible, make and retain a copy of the test..

Directions for Student:

• Completely document your work.

• Numerical answers should be correct to 3 significant figures. You may round off given numerical information to a precision consistent with this standard.

• Undocumented and unjustified answers may be counted wrong, and in the case of two-choice or limited-choice answers (e.g., true-false or yes-no) will be counted wrong. Undocumented and unjustified answers, if wrong, never get partial credit. So show your work and explain your reasoning.

• Due to a scanner malfunction and other errors some test items may be hard to read, incomplete or even illegible. If this is judged by the instructor to be the case you will not be penalized for these items, but if you complete them and if they help your grade they will be counted. Therefore it is to your advantage to attempt to complete them, if necessary sensibly filling in any questionable parts.

• Please write on one side of paper only, and staple test pages together.

Pratice test CH2 second submission

CH 2 pratice test

course Mth 151

..1A survey of 100 families showed that

35 had a dog

28 had a cat

10 had a dog and cat

42 had neither a dog a cat nor a parakeet

0 had a dog and a cat and parakeet

How many had a parakeet?

5 had a parakeet I used the square with the circles inside digram to find that 53 ppl own a dog or/and cat plus the 42 that have neither leaves 5 to own just a parakeet

Very good.

.

.

.

.

.

.

.

.Complete the blank with E or E/ to make the statement true

9_{6,11,4,9,11} ?

I insert an E/ because those two things are not equal

.

.

.

.

.

.

.find the number of proper subsets for the set ?

{1,2,3….,8}

.

.I donot know how to figure this without writing out all possibilites which leaves a lot of room for error, how do I caculate this?

Also what is builder notation? If u ask me to write a set in builder notation?

There are 8 elements in the set, so there are 2^8 possible subsets. One of the subsets is equal to the set and hence not a proper subset. The other 2^8 - 1 are proper subsets. 2^8 = 256 so there are 255 proper subsets.

One way to describe this set in set-builder notation would be

{x | x is a counting number between 1 and 8, inclusive}.

.

.

.

.

.

.

.

.t or F

(6+10,18+10)=(6,18) ?

fALSE

THe reason is obvious but you have to get the reason. Just 'true' or 'false' is never an acceptable answer.

.

.

.

.

.

.

.T or F

13 ,E/, C ?

I would say False but I don’t know 13 could be a part of a set C that im unaware or

This problem would either be omitted or, given and answer such as yours that shows you know what the notation means, counted as correct.

.

.

.

.

.

.

.U={q,r,s,t,u,v,w,x,y,z}

A={q,s,u,w,y}

.B={q,s,y,z}

C={v,w,x,y,z} \

List elements in (A^B)’ ?

(A^B)’ = {r,t,u,v,w,x,z}

good

Because the (A^B) is {q,s,yz} so (A^B)’ which is everything not found in the intersection of a and b, leaves {r,t,u,v,w,x,z}

’

.

.

.

.

.

.

.

.

.Find the cardinal number of set {1/2,1/4,1/8,1/16,…} ?

It’s that symbol for infinate the funny x with a 0in the bottom right corner as this set never ends

that symbol is called aleph-null; any reasonable attempt to write the symbol would be accepted.

.

.

.

.

.

.

.

.

N(U)=60

N(A)=27

N(B)=-19

N(AUB)=6

I expect this latter is n (A ^ B), since A U B can't contain fewer elements that either of the sets A and B.

Find (AUB)’ ?

I drew a vien digram

21+6+13=40

U=60-40=20 which is what is left outside A and B there fore (AUB)’

.20

good

.

.

.

.

.

.

.

.U=all soda pops

A=all diet soda

B=all cola soda pops

C=all soda pops in cans

D=a;; caffine free soda pops

Describe this set in words A^B^D ?

All sodas that are diet, cola, and caffeine free

Maybe better said as

.All soda pops that are diet and also colas, and aslo caffine free.

Good.

sorry if i have made a silly mistake Im just wanting to get this right to help me be sucessful in the course and I have looked over this and cannot understand the error

See my notes. You're in good shape.

Your second submission of the practice test was good; I didn't recognize it for what it was, which was my fault.
