19cm
18cm
17cm
12cm
Correct answer is A
From the diagram
sin 70o = \(\frac{x}{10}\)
x = 10sin 70o
= 9.3969
Hence, length of chord MN = 2x
= 2 x 9.3969
= 18.7938
= 19cm (nearest cm)
\(\frac{n}{2} + \frac{5}{2}\)
\(\frac{n}{2}\) - 5
5 - \(\frac{n}{2}\)
\(\frac{n}{2}\) + 5
Correct answer is D

Correct answer is B
Let a represent an interior angle; e represent an exterior angle. A section of the polygon is down in the diagram.
\(\frac{e}{a}\) = \(\frac{l}{11}\) given
a = 11e
a + e = 180o(angles on a straight line)
11e + e = 180o
12e = 180o
e = \(\frac{180^o}{12}\)
= 15o
Hence, number of sides
= \(\frac{360^o}{\tect{size of one exterior angle}\)
= \(\frac{360^o}{14^o}\)
= 24
Find the lower quartile of the distribution illustrated by the cumulative frequency curve

Correct answer is B
Lower quartile,
Q1 = \(\frac{1}{4}\)Nth term
= \(\frac{1}{4}\) x 600th term
= 150th term
= 15.5 + 3 + 0.5
= 19
