Correct answer is C
59.81798 = 59.8(3 s.f)
0.0746829 = 0.0747
59.8 x 0.0747 = 4.46706
= 4.47(3s.f)
\(\frac{7}{13}\)
\(\frac{5}{13}\)
\(\frac{6}{13}\)
\(\frac{8}{13}\)
\(\frac{4}{13}\)
Correct answer is C
Vowels of letters are 6 in numbers
prob. of vowel = \(\frac{6}{13}\)

Correct answer is B
\(\begin{array}{c|c} Scores & Frequency \\\hline 55 & 1\\ 60 & 4\\ 65 & 6\\ 70 & 4\\ 75 & 1 \end{array}\)
Median = 65(middle number)
Mode = 65(most common)
Median + Mode = 65 + 65 = 130
15o, 25o, 35o, 40o, 65o
60o, 100o, 140o, 160o, 260o
6o, 10o, 14o, 16o, 26o
30o, 50o, 70o, 80o, 130o
none of the above
Correct answer is D
6 + 10 + 14 + 16 + 26 = 72
\(\frac{6}{72}\) x 360
= 30o
Similarly others give 30o, 50o, 70o, 80o and 130o respectively

Correct answer is A
When x = -2, y = x3 - x + 3
= -23 - (-2) + 3
= -8 + 2 + 3
= -3
