Question

Which of the following is an example of a formula that performs a mathematical calculation on values in a worksheet?

(a) =A1+A2+A3
(b) =SUM(A1:A10)
(c) =AVERAGE(A1:A10)
(d) All of the above

Answer 1

All options (a), (b), and (c) are examples of formulas that perform mathematical calculations on values in a worksheet, therefore the correct answer is (d) All of the above.

Step-by-step explanation:

The student's question asks which of the following examples is a formula that performs a mathematical calculation on values in a worksheet:

(a) =A1+A2+A3

(b) =SUM(A1:A10)

(c) =AVERAGE(A1:A10)

(d) All of the above

All these choices represent formulas that perform calculations on spreadsheet data. Choice (a) directly adds the values of cells A1, A2, and A3. Choice (b) calculates the sum of values in a range from A1 to A10. Choice (c) computes the average of values in the same range. Thus, the correct answer to the question is:

(d) All of the above

Answer 2

These formulas represent different mathematical operations—addition, summation, and finding averages—performed on values within a worksheet.

Thus option d is correct.

Explanation:

The formulae mentioned—(a) =A1+A2+A3, (b) =SUM(A1:A10), and (c) =AVERAGE(A1:A10)—represent different mathematical calculations in a worksheet. Formula (a) adds the values in cells A1, A2, and A3. Formula (b) utilizes the SUM function to add values within the range A1 to A10. Formula (c) uses the AVERAGE function to calculate the average of values in the range A1 to A10.

The formula (a) =A1+A2+A3 simply adds the values in the specified cells, summing them together. For instance, if A1=5, A2=10, and A3=15, the result would be 5+10+15=30.

Formula (b) =SUM(A1:A10) employs the SUM function to add up all the values within the range A1 to A10. If A1=2, A2=4, ..., A10=20, the result would be 2+4+...+20=110.

Meanwhile, formula (c) =AVERAGE(A1:A10) uses the AVERAGE function to find the average of values in the range A1 to A10. If the values in A1 to A10 range from 1 to 10, the average would be (1+2+...+10)/10 = 55/10 = 5.5.

In summary, these formulas demonstrate different mathematical operations in Excel or similar spreadsheet software, from simple addition (a) to summation (b) and calculating averages (c) within specified ranges or cells. Each serves a distinct purpose, catering to various mathematical calculations within a worksheet.

Therefore option d is correct.
