x 2 4 7 8 9 |
(\(\bar{x} - \bar{x}\)) -4 -2 1 2 4 |
(\(\bar{x} - \bar{x})^2\) 16 4 1 4 9 _________ \(\sum (x - x)^2\) = 34 |
\(\bar{x} = \frac{2 + 4 + 7 + 8 + 9}{5} = 6
variance = \(\frac{34}{5}\)
= 6.8
70\(^o\)
58\(^o\)
55\(^o\)
48\(^o\)
Correct answer is B
x = 180\(^o\) - (52\(^o\) + 70\(^o\))
= 180\(o\) - 122\(^o\)
= 58\(^o\)
70\(^o\)
60\(^o\)
52\(^o\)
18\(^o\)
Correct answer is C
∠QRT = ∠SRT = 52 (opposite angles)
∠SRT = y = 52 (alternate angles)
y = 52\(^o\)
11cm
22 cm
44 cm
80 cm
Correct answer is C
Z\({O}\)T = 2 x 70\(^o\) 140\(^o\)
Length = \(\frac{\theta}{360}\) x 2\(\pi\)r
\(\frac{140^o}{360} \times 2 \times \frac{22}{7}\) x 18
= 44cm
56\(^o\)
75\(^o\)
16\(^o\)
15\(^o\)
Correct answer is D
Sin\(\theta = \frac{20}{75}\)
\(\theta = sin^{-1} (\frac{20}{75})\)
= 15\(^o\)
