Answer Key 3

FINAL Answer key : 198:110 Intro to Computers Summer 2007

When you are grading, wherever possible, be lenient. When you have a choice to take more or less points off - you should usually take less points off. The scores will not be especially high as it is, so don't feel like you have to be a real strict grader. Students have worked pretty hard this summer - so it is time to be a little bit nice.

Part A

1. wireless 2. flash drive 3. ink jet 4. ASCII 5. relational 6. google

7. appleworks 8. ram 9. SUM

Part B

1. J 2. D 3. B 4. O 5. H 6. E 7. M 8. C 9. L 10. K 11. I 12. N

Part C

1. D 2. A 3. B 4. C 5. A 6. C 7. A 8. D 9. E 10. B 11. D 12. C

Part D

1. = B8 - C8

2. = SUM(C5:C8)

3. = D5 / $E$1

4. = IF(C6 < B6, "Within Budget", "Over Budget")

5. $ 3875 ($ doesn't have to be in answer.)

Part E

1. Grant 1868 General 93 1332 Julia

2. Roosevelt, F 1932 Governor 635 3687 Eleonor

3. Lincoln, Clinton

4a. Elected: < 1900 and also Wife: Martha (1 point each part)

4b. Click All

Part F

1. 1 2. 10 3. 6

SELECT CASE C

CASE 1, 10

PRINT "Key Value"

CASE 1 TO 5

PRINT "Minor"

CASE 5 TO 10

PRINT "Medium"

CASE IS < 25

PRINT "Plenty"

CASE ELSE

PRINT "A lot"

END SELECT

(other variations also possible)

5. 12 6. 37 7. LET Chosen = INT(RND * 8) + 24

FOR Val = 40 TO 60 STEP 5

PRINT Val

NEXT Val

9a. No 9b. Before (1 point each part)

Part G

need LET after ELSE within the IF
need semicolon (;) before Triangle within the PRINT
remove quotes around 5 in DATA, it should be number not string

Input statement needs PROMPT
the first CASE needs to have the IS removed; or alternatively an = can be after the IS
has to be CASE ELSE (not just ELSE)

program is missing an END statement
Need DO in front of UNTIL
should be NEXT Innings (not NEXT Batter)
LET can't have two assignments in it, that is, two variables not allowed

Part H

(1/2 point each item, but round down; so one or two wrong is -1)

Whoops, missed 4
And finally 3

(one point associated with 1st, 3rd and 4th line; 2 points for 2nd line)

Part I

(possible answer)

INPUT PROMPT "What weight did you start with?": Weight
LET Goal = .9 * Weight
LET Week = 0
DO WHILE Weight > Goal

LET Week = Week + 1
PRINT "It is currently week #"; Week
INPUT PROMPT "How much did you lose?": Loss
LET Weight = Weight - Loss
PRINT "Your current weight is "; Weight

LOOP
PRINT "Congratulations, you reached your goal after "; Week; " week(s)."
END

Advice on grading

15 Points if perfect. 13-14 points if minor syntax or logic errors. 9-12 if one significant piece missing. 5-8 if several parts right or close (INPUT PROMPTs, PRINTS, structure of DO, LET calculations, END ) 0-4 if very little right, or if code uses little real BASIC.

Remember, if anything be lenient.

Part J

(possible answer)

DIM Name$(100), Violation$(100), Fine(100)
FOR F = 1 TO 100

READ Name$(F), Violation(F), Fine(F)

NEXT F

LET TotalFines = 0
FOR J =1 TO 100

LET TotalFines = TotalFines + Fine(J)

NEXT J

IF TotalFines > 10000 THEN

FOR K = 1 TO 100

IF Violations$(K) <> "Speeding" THEN LET Fine(K)=Fine(K)/2

NEXT K

END IF

PRINT "Name","Violation","Amount"
FOR L=1 TO 100

PRINT Name$(L), Violation(L), Fine(L)

NEXT L
END

Advice on grading. 15 Points if perfect. 13-14 points if minor syntax or logic errors. 9-12 if significant piece missing. 5-8 if several parts right or close (INPUT, PRINTS, DIM, arrays used correctly, structure of FOR loops, structure of IF, END ) 0-4 if very little right, or if code uses little real BASIC.
