Question

question 9 points 2 which rule is used correctly to determine the number of significant digits in a number? zeros in between non - zero values are significant digits. zeros to the right of non - zero digits are not significant. zeros to the left of the first non - zero digit are significant. all of the choices.

Explanation:

• Zeros between non-zero digits are always significant (e.g., 105 has 3 significant digits).
• Zeros to the right of non-zero digits can be significant if there is a decimal point (e.g., 100. has 3 significant digits), so the second option is incorrect.
• Zeros to the left of the first non-zero digit are placeholders and not significant (e.g., 0.0012 has 2 significant digits), so the third option is incorrect.

Since only the first statement is correct, "All of the choices" is also wrong.

Answer:

Zeros in between non-zero values are significant digits.
