By default, your numerical entry is scored as correct if it is within 1% of the correct answer. A rule of thumb is always to enter at least 3 digits for numerical questions.
If the correct answer is 7.48809, which of the following entries would be counted as correct? That is, which entries are within WebAssign's default tolerance? (Select all that apply.)
0.01 * 7.48809 = 0.07488
7.48809 - 0.07488 = 7.41321
7.48809 + 0.07488 = 7.56297

To determine which entries would be counted as correct within WebAssign's default tolerance (within 1% of the correct answer), we need to calculate the range of acceptable values.
Given that the correct answer is 7.48809, we can calculate the acceptable range by considering a tolerance of 1%. To do this, we need to find the upper and lower bounds of the acceptable range.
Upper bound:
7.48809 + (1% * 7.48809) = 7.48809 + 0.0748809 = 7.5629709
Lower bound:
7.48809 - (1% * 7.48809) = 7.48809 - 0.0748809 = 7.4132091
Therefore, any entry between 7.4132091 and 7.5629709 (inclusive) would be considered correct within WebAssign's default tolerance.
Now, let's examine the provided options to determine which ones fall within this acceptable range.
