Identify which of the following Formula is wrong =(B5) *7C =Sum(B3:B5) =23+45–Sum(B5:B9) =SUM(23+45)/(SUM(B5:B9))

1. Break Down the Problem

We need to analyze each formula provided and determine whether it is correctly formulated or not.

2. Relevant Concepts

We will look for issues related to syntax, formula usage, and results based on standard spreadsheet functions.

3. Analysis and Detail

1. Formula 1: (B5) * 7C

   • This formula is incorrect because 7C is not a valid expression or reference in standard formulas. It seems to be a typo or syntax error.

2. Formula 2: =Sum(B3:B5)

   • This formula is correct. It sums the values in cells B3, B4, and B5.

3. Formula 3: =23 + 45 – Sum(B5:B9)

   • This formula is also correct. It adds 23 and 45 together and then subtracts the sum of the range B5 to B9.

4. Formula 4: =SUM(23 + 45) / (SUM(B5:B9))

   • This formula is partially correct but misleading. The SUM(23 + 45) would return 68 since SUM here just returns the total of the number since it only contains one expression. This can lead to confusion as typically SUM is used to sum a range of numbers.

4. Verify and Summarize

• The first formula is clearly wrong due to an invalid reference (7C).
• The second and third formulas are correct.
• The fourth formula is correct but unorthodox in usage, and it may not represent the intended operation or convey the conventional use of SUM.

Final Answer

The incorrectly formulated expression is Formula 1: (B5) * 7C.
