113\(^o\)
106\(^o\)
Correct answer is A
L\(N\)M = 180\(^o\) - (74\(^o\) + 39\(^o\))
180\(^o\) - 113\(^o\)
= 67\(^o\)
L\(^O\)
M = x = 2 x 67\(^o\)
= 134\(^o\)
If (x + 2) is a factor of x\(^2\) +px - 10, find the value of P.
3
-3
7
-7
Correct answer is B
x + 2 = 0
x -2
x\(^2\) = px - 10 = 0
(-2)\(^2\) - 2p - 10 = 0
4 - 2p - 10 = 0
\(\frac{-2p}{-2} = \frac{6}{-2}\) \(\to\) p = -3
y = 8.0
y = 8.5
y = 9.0
y = 9.5
Correct answer is B
If x = -2.5
y = 8.5
(2.0, 9.0) and (-1.5, 2.0)
(2.0, 8.5) and (-1.5, 2.0)
(2.0, 8.0) and (-1.5, 2.5)
(2.0, 7.5) and (-1.5, 2.5)
Correct answer is A
The point of intersection are (2.0, 9.0) and (-1.5, 2.0)
The interquartile range of distribution is 7. If the 25th percentile is 16, find the upper quartile.
35
30
23
9
Correct answer is C
Q\(_3\) - Q\(_1\) = 7
Q\(_3\) - 16 = 7
Q\(_3\) - 7 + 16
= 23
