Evaluate \(^{n^2 + 1}\)C\(_{n+5}\) if n = 3
55

25
Correct answer is B
\(^{3^2 + 1}\)C\(_{3+5}\)
\(^{9 + 1}\)C\(_{3+5}\)
\(^{10}\)C\(_{8}\) = \(\frac{10!}{8! 2!}\)
\(\frac{10 * 9 * 8!}{8! 2!}\) = \(\frac{10 * 9}{2}\)
= 45
The coordinates of the mid-point of the line joining the points (-3,5) and (2,10) is given by?
( \(\frac{1}{2}\), \(\frac{15}{2}\) )
( \(\frac{1}{2}\), \(\frac{-15}{2}\) )
( \(\frac{-1}{2}\), \(\frac{-15}{2}\) )
( \(\frac{-1}{2}\), \(\frac{15}{2}\) )
Correct answer is D
Given Data: x\(_1\) = -3, x\(_2\) = 2, y\(_1\) = 5, y\(_2\) = 10
coordinates of the mid-point of the line = (\(\frac{x_1 + x_2}{2}\) , \(\frac{y_1 + y_2}{2}\))
(\(\frac{-3 +2}{2}\) , \(\frac{5 + 10}{2}\))
= \(\frac{-1}{2}\)) , \(\frac{15}{2}\))

1000
2000
4000
Correct answer is C
if 20 students = 10000
: #500 per student
#1,000,000 ÷ 500
= 2,000 cover students
The equivalent of (10110.011)\(_2\) in base 10 is?
26.325
24.372
42.443
22.375
Correct answer is D
Using the expansion method on (10110.011)\(_2\)
(1 * 2\(^4\)) + (0 * 2\(^3\)) + (1 * 2\(^2\)) + (1 * 2\(^1\)) (0 * 2\(^0\)) + (0 * 2\(^{-1}\)) + (1 * 2\(^{-2}\)) + (1 * 2\(^{-3}\))
(1*16) + 0 (1*4) + (1*2) + 0 + 0 + (1*\(\frac{1}{4}\)) + (1*\(\frac{1}{8}\))
16 + 4 + 2 + (0.25 + 0.125)
22 + 0.375
(10110.011)\(_2\) = 22.375\(_{10}\)
