Answer:
C is probably the best answer
Answer:
I. 4.8; 40
II. 0.12
Explanation:
Given the following numerical values;
a. 4.793 (it is correct to 4 significant figures).
To 3 significant figures, we have;
4.793 = 4.79
To 2 significant figures, we have;
4.793 = 4.8
b. 39.51 (it is correct to 4 significant figures).
To 3 significant figures, we have;
39.51 = 39.5
To 2 significant figures, we have;
39.51 = 40
