### What is the shorter way of computing = C1+C2+C3+C4+C5+C6+C7+C8?

• A.

• B.

B. TOTAL (C1:C8).

• C.

C. SUM (C1:C8).

• D.

D. C1:C8.

C. C. SUM (C1:C8).
Explanation
The correct answer is c. SUM (C1:C8). This is the shorter way of computing the sum of C1 to C8. The SUM function in most spreadsheet software allows you to add up a range of cells by specifying the starting and ending cell references. In this case, C1:C8 represents the range of cells from C1 to C8, and using the SUM function with this range will give you the sum of all the values in those cells.

### Writing an incorrect formula that attempts to perform math by referring to a text entry causes excel to display what in the formula cell?

• A.

Error

• B.

Value

B. Value
Explanation
When writing an incorrect formula that attempts to perform math by referring to a text entry, Excel will display "Value" in the formula cell. This means that Excel is unable to calculate the formula due to the presence of a text entry, which is not a valid input for mathematical operations. Therefore, instead of displaying an error message, Excel shows "Value" to indicate that the formula cannot be evaluated.

### Line charts are most appropriate for:

• A.

A. Showing trends or changes over time.

• B.

B. Comparing individual values at specific times.

• C.

C. Showing relationships among portions of a whole.

• D.

D. None of the above.

A. A. Showing trends or changes over time.
Explanation
Line charts are most appropriate for showing trends or changes over time because they visually represent the relationship between two variables on a continuous scale. By plotting data points and connecting them with lines, line charts effectively illustrate how the values of a variable change over a specific period. This makes them ideal for analyzing patterns, identifying trends, and understanding the direction and magnitude of changes over time. Comparing individual values at specific times or showing relationships among portions of a whole are better suited for other types of charts, such as bar charts or pie charts.

Rate this question:

A. Showing trends or changes over time.

• B.

B. Comparing individual values at specific times.

• C.

C. Showing relationships among portions of a whole.

• D.

D. None of the above.

C. C. Showing relationships among portions of a whole.
Explanation
Pie charts are most appropriate for showing relationships among portions of a whole because they visually represent the proportion of each category in relation to the total. The size of each slice in the pie chart corresponds to the percentage or proportion it represents, making it easy to compare the relative sizes of each category. This allows for a clear understanding of the distribution and relationship between different parts of the whole.
