\(\frac{3}{10}\)
\(\frac{2}{9}\)
\(\frac{5}{18}\)
\(\frac{7}{10}\)
Correct answer is D
\(\frac{\text{education}}{\text{graduates}} = \frac{108}{360} \times 4320\)
= 1296
Pr(Education) = \(\frac{1296}{4320} = \frac{1}{10}\)
pr(not education) = 1 - \(\frac{3}{10}\)
= \(\frac{10 - 3}{10}\)
= \(\frac{7}{10}\)
840
864
920
960
Correct answer is B
\(\frac{\text{science}}{\text{graduates}}\) = \(\frac{\theta}{360}\) x 4320
where \(\theta\) + 100 + 80 + 108 = 360
\(\theta\) = 360 - 288 = 360
\(\frac{\text{science}}{\text{graduates}}\) = \(\frac{72}{360} \times 4320\)
= 864
In the diagram, angle 20o is subtended at the centre of the circle, find the value of x
30o
50o
80o
100o
Correct answer is B
2(30 + x) = 360 - 200
60 + 2x = 160
2x = 160 - 60
2x = 100
x = \(\frac{100}{2}\)
x = 50
If /XY/ = 50m, how far cast of X is Y?
25.5m
40.6m
40.8m
43.3m
Correct answer is D
Required distance = x
where \(\frac{1}{50m}\) = sin 60 x 50m x 0.866
x = 43.3m
