Question

serena wants to add the numbers appearing in cells d3:d9 and then place the result in cell d10. what function should she use in cell d10 to get the desired result?
a =add(d3:d9)
b =average(d3:d9)
c =count(d3:d9)
d =sum(d3:d9)

Explanation:

The question requires summing numbers in cells D3:D9. Option A's =ADD is not a standard spreadsheet function for this purpose. Option B calculates the average, not the sum. Option C counts cells with numbers, not their total. Option D uses =SUM, the standard function to add values in a range, which matches the requirement.

Answer:

D. =SUM(D3:D9)
