Reflection on Homework for Week 7 March 26, 2012

Filed under: Homework — computer_resources @ 4:51 am

Dear students,

Sorry for late marking of your homework!  I have tonnes of work to be done at UBD; my assignments, group working activities, meetings…. pheewww!! at last your homework completely checked~

So please have a check… I have came across that some of you haven’t submit your work.  They are Khairurrabi’ee, Hazwan, and Joane.

Here is a good example that I would like to acknowledge Muhd  Faris Syarifuddin bin Hj Hirwan.  He organised his table well by formating it with borders and colours.  Very neat, indeed!!  (*** DOUBLE CLICK ON THE IMAGE TO GET A FULL IMAGE)

i. D2: =B2*C2
ii. B8: =MAX(B2:B6)
iii. B9: =MIN(B2:B6)
iv. D10: =SUM(D2:D6) / =D2+D3+D4+D5+D6

 

(b)  Pick one from the table above for:

i. Label: Rice. (Other answers: Item, Quantity, Cost Price, Total Cost, Shirts, Shoes, Drinks, Gas, Rice, Maximum Quantity, Minimum Quantity, Total cost of all the items)

ii. Numbers: 3.  (Other answers: 4, 7, 2, 5, 25, 30, 12, 10, 13)

 

(c)  Using a pencil, shade cells A7:D7. (SEE TABLE ABOVE)

 

(d) If the display in cell C2 appears as “######’

The spreadsheet below shows the results of student progress assessment (SPA) of core subjects for some year 8 students in a school.

a)     Write down a cell address which contains

i.   a label: A1 (other answers: B1, C1, D1, E1, F1, G1, H1, A2, A3, A4, A5. A6, A7)

ii.   a date: B2 (other answers: B3, B4, B5, B6, B7)

 

b)     What is the formula/function used to calculate the following:

i.  Total in G2: =SUM(C2:F2)

other answer: =C2+D2+E2+F2

ii.  Average in H2: =AVERAGE(C2:F2)

other answer: =(C2+D2+E2+F2)/4

 

c)     The display in cell H2 appears as “######’

i. What does this mean?

The cell is not wide enough to display its item.

ii.   How would you overcome this problem?

By widening the column so that the item can be displayed properly.

 

d)     Describe how you would copy the formula from G2 to G3:G7.

1.  Select cell G2, right-click on the mouse and select ‘Copy’.

2. Highlight cell G3:G7, right-click on the mouse and select ‘Paste’.

 

e)     List two of a function in a spreadsheet. (I’ve made change from formula to function)

1. =SUM(C2:G2)

2. =AVERAGE(c2:G2)

*The range can be anything.
