If A = {a,b,c}, B = {a,b,c,d,e} and C = {a,b,c,d,e,f}. Find (A∪B)∩(A∪C)
{a,b,c,d}
{a,b,c,d,e}
{a,b,c,d,e,f}
{a,b,c}
Φ
Correct answer is B
A = {a, b, c}; B = {a, b, c, d, e}; C = {a, b, c, d, e, f}
(A \(\cup\) B) = {a, b, c, d, e}
(A \(\cup\) C) = {a, b, c, d, e, f}
(A \(\cup\) B) \(\cap\) (A \(\cup\) C) = {a, b, c, d, e}
What percentage of the population are married? correct to one decimal place
14.8%
20.4%
30.5%
35.2%
36.5%
Correct answer is D
Married = 550 + 400 = 950
Married% = \(\frac {950}{2700}\) x \(\frac {100}{1}\)
=35.2%
What angle represents grown up girls ? Correct to one decimal place
37.5o
26.7o
25.7o
20o
3.75o
Correct answer is B
Total population = 1400 + 550 + 200 + 150 + 400 = 2700
grown up girls = 200
= \(\frac {200}{2700}\) x \(\frac {360}{1}\)
=80/3 = 26.7°
Solve the following equation: 6x\(^2\) - 7x - 5 = 0
x = 1/2 or x = -21/2
x = 1/3 or x = 21/2
x = 1 2/3 or x = -1/2
x = 12/3 or x = 1/2
x = 5/6 or x = -1
Correct answer is C
6x\(^2\) - 7x - 5 = 0
6x\(^2\) - 10x + 3x - 5 = 0
2x(3x - 5) + 1(3x - 5) = 0
(2x + 1)(3x - 5) = 0
x = \(\frac{5}{3}\) or x = \(-\frac{1}{2}\)
126.5cm2
165cm2
176cm2
214.5cm2
253.5cm2
Correct answer is D
since it is an open cylinder; r= 3.5cm = 7/2cm
h= 8cm;
S.A = 2πrh + πr 2
= πr(2h + r)
(16 + 3.5); 11 x 19.5 = 214.5cm2
