Solve the questions but using English language

Here are the solutions to the questions:

a)
i. To calculate the Total Marks for the student David, the formula will be:

$$\boxed{=\text{SUM(B4:D4)}}$$

ii. To calculate the Average Marks for Alice, the formula will be:

$$\boxed{=\text{AVERAGE(B1:D1)}}$$

b) Two advantages of using electronic spreadsheets over manual spreadsheets are:

• Accuracy and Automation: Electronic spreadsheets perform calculations automatically, reducing human errors and ensuring data accuracy.
• Efficiency and Speed: They allow for easy and fast entry, updating, and analysis of large amounts of data, saving significant time compared to manual spreadsheets.

c) The difference between "=sum ()" and "=A+B" is:

• =SUM(): This is a function used to sum an entire range of cells (e.g., =SUM(A1:A5)) or multiple individual cells (e.g., =SUM(A1, B1, C1)). It is suitable for summing large datasets.
• =A+B: This is an arithmetic operator used to sum the values of two specific cells (e.g., $A1+B1$). It is typically used for summing only a few cells.

d) Three features of an MS Word window are:

• Ribbon: This is the area at the top of the window containing tabs like Home, Insert, Page Layout, etc., which house groups of related commands.
• Title Bar: This is the topmost part of the window that displays the name of the document you are currently working on and the program name (Microsoft Word).
• Status Bar: This is the bottommost part of the window that displays information about the document, such as the current page number, word count, and language in use.
