Correct answer is C
(3 x 0) + (1 x 2) + (5 x 2) + (5 x 3) + (5 x 4) +
(10 x 5) + (4 x 6) + (3 x 7) + (1 x 8) + (2 x 9) \(\div\) 40
= \(\frac{168}{40}\) = 4.2

Correct answer is A
3 + 2 + 5 + 5 + + 5 + 10 + 4 + 3 + 1 + 2 = 40
Rationalize \(\frac{\sqrt{6} - \sqrt{4}}{\sqrt{6} + \sqrt{4}}\)
5 + 2 \(\sqrt{6}\)
5 - 4 \(\sqrt{6}\)
5 + 4 \(\sqrt{6}\)
5 - 2 \(\sqrt{6}\)
Correct answer is D
\(\frac{\sqrt{6} - \sqrt{4}}{\sqrt{6} + \sqrt{4}}\) = \(\frac{6-2\sqrt{6} - 2\sqrt{6} + 4}{6 - 4}\)
\(\frac{10 - 4\sqrt{6}}{2}\) = 5 - 2\(\sqrt{6}\)

Correct answer is C
\(\frac{10 + 8 + 5 + 11 + 12 + 9 + 6 + 3 + 15 + 23}{10}\)
= \(\frac{102}{10}\) = 10.2
