Simplify \(\left(\frac{3}{4} - \frac{1}{3}\right)\times 4\frac{1}{3}\div 3\frac{1}{4}\)
\(\frac{5}{9}\)
\(\frac{5}{16}\)
\(\frac{8}{13}\)
\(\frac{16}{5}\)
Correct answer is A
\((\frac{3}{4} - \frac{1}{3}) \times 4\frac{1}{3} \div 3\frac{1}{4}\)
= \((\frac{9 - 4}{12}) \times \frac{13}{3} \div \frac{13}{4}\)
= \(\frac{5}{12} \times \frac{13}{3} \times \frac{4}{13}\)
= \(\frac{5}{9}\)

70o
Correct answer is B
< MNT = < MTN = 32°
< NMT = 180° - 2(32°) = 116°
< OMN + < NMT + < LMO = 180°
20° + 116° + < LMO = 180° \(\implies\) < LMO = 180° - 136° = 44°
< LMN = < LMO + < OMN
= 44° + 20° = 64°
< NOM = 180° - 2(20°) = 140°
< NLM = \(\frac{1}{2} \times < NOM = 70°\)
< LNM + < LMN + < NLM = 180°
< LNM + 64° + 70° = 180°
< LNM = 180° - 134° = 46°

\(\frac{7}{10}\)
\(\frac{2}{5}\)
\(\frac{3}{5}\)
\(\frac{1}{5}\)
Correct answer is A
Number of at most 8 goals = 7
P(at most 8 goals) = \(\frac{7}{10}\)
Given that \(p = x-\frac{1}{x} and\hspace{1mm}q = x^2 + \frac{1}{x^2}\) express q in terms of p.
(p2 + 2)
(p - 2) 2
(p + 2) 2
(p2 - 2)
Correct answer is A
Given \(p = x - \frac{1}{x}\); \(q = x^2 + \frac{1}{x^2}\).
\(p^2 = (x - \frac{1}{x})(x - \frac{1}{x})\)
\(p^2 = x^2 + \frac{1}{x^2} - 2\)
\(p^2 = q - 2 \implies q = p^2 + 2\)
