2.5
56.0
56.2
56.3
6.5
Correct answer is B
Total score for 2A & 2B = 4200
mean score = \(\frac{4200}{40 + 35}\)
= \(\frac{4200}{75}\)
= 56
6\(\frac{1}{3}\)
20
21
176\(\frac{4}{9}\)
None of the above
Correct answer is C
y = \(\frac{4x}{9}\) + 1, z = \(\frac{4y}{9}\) + 1, z = \(\frac{4}{9}\)(\(\frac{4}{9}\) x + 1) + 1
= [\(\frac{4}{9}\)(\(\frac{4}{9}\)(99) + 1]
= \(\frac{4}{9}\)(45) + 1
= 21
\(\frac{2}{n + 1}\)
(-1)n + 1 \(\frac{2}{n + 1}\)
(-1)n \(\frac{2}{n + 1}\)
\(\frac{n}{2n - 1}\)
(-1)n\(\frac{n}{2n - 1}\)
Correct answer is C
(-1, \(\frac{2}{3}\), -\(\frac{1}{2}\), \(\frac{2}{5}\)......)
nthterm is (-1)n\(\frac{2}{n + 1}\)
Since (-1)n will always be negative for n = odd
What factor is common to all the expressions x2 - x, 2x2 + x - 1 and x2 - 1?
x
x + 1
x - 1
No common factor
(2x - 1)
Correct answer is D
x2 - x = x(x - 1)
= 2x2 + x - 1
= (2x - 1)(x + 10
x2 - 1 = (x + 1)(x - 1)
No factor
Make c the subject of formula v = 1 - \(\frac{a}{5}\)(b + \(\frac{3c}{7}\))
[\(\frac{7}{3}\) + \(\frac{5}{a}\)(v - 1)] + b
[\(\frac{7b}{3}\) + \(\frac{5}{a}\)(v - 1)]
\(\frac{7}{3}\)[b + \(\frac{5}{a}\)(v - 1)]
\(\frac{7}{3}\)[b + \(\frac{5v - 1}{a}\)]
Correct answer is A
