Simplify \(\frac{x - 4}{4} - \frac{x - 3}{6}\)
\(\frac{x - 18}{12}\)
\(\frac{x - 6}{12}\)
\(\frac{x - 18}{24}\)
\(\frac{x - 6}{24}\)
Correct answer is B
\(\frac{x - 4}{4} - \frac{x - 3}{6}\) = \(\frac{3(x - 4) - 2(x - 3)}{12}\)
= \(\frac{3x -12 - 2x + 6}{12}\)
= \(\frac{3x - 2x - 12 + 6}{12}\)
= \(\frac{x - 6}{12}\)
25
\(\frac{1}{5}\)
1
\(\frac{1}{25}\)
Correct answer is C
\(\frac{25 \frac{2}{3} \div 25 \frac{1}{6}}{( \frac{1}{5})^{-\frac{7}{6}} \times ( \frac{1}{5})^{\frac{1}{6}}}\) = \(\frac{25^{4 - \frac{1}{6}}}{(\frac{1}{5})^{-7 + \frac{1}{6}}}\)
= \(\frac{25^{\frac{1}{2}}}{(\frac{1}{5})^{-1}}\)
= \(\frac{(5^2)^{\frac{1}{2}}}{(5^{-1})^{-1}}\)
= \(\frac{5}{5}\)
= 1
Simplify: 11011\(_2\) - 1101\(_2\)
101000\(_2\)
1100\(_2\)
1110\(_2\)
1011\(_2\)
Correct answer is C
11011\(_2\) - 1101\(_2\) = 1110\(_2\)
Evaluate (0.13)\(^3\)correct to three significant figures
0.00219
0.00220
0.00300
0.00390
Correct answer is B
(0.13)\(^3\) = 0.13 x 0.13 x 0.13 = 0.002197
= 0.00220 (3 s.f)
10%
20%
50%
60%
Correct answer is C
Number that score less than 5: 5 + 6 + 4 + 3 + 2 = 20
Total number of students: 5 + 6 + 4 + 3 + 2 + 4 + 6 + 5 + 1 + 3 + 1 = 40.
%age of students that failed: \(\frac{20}{40} \times 100% = 50%\)
