1.639 x 10\(^2\)
1.639 x 10\(^1\)
1.639 x 10\(^{-1}\)
1.639 x 10\(^{-2}\)
Correct answer is C
\(\frac{0.42 \div 2.5}{0.5 \times 2.05} = \frac{0.168}{1.025}\)
= 1.639 x 10\(^{-1}\)

Correct answer is D
Mean = \(\frac{8 + 18 + 10 + 14 + 18 + 11 + 13 + 14 + 13 + 17 + 15 + 8 + 16 + 13}{14}\)
Mean = \(\frac{188}{14}{\)
Mean = 13.4
Number above the mean is 7
