How good are you with figures and formulas? Find out with these Mathematics past questions and answers. This Test is useful for both job aptitude test candidates and students preparing for JAMB, WAEC, NECO or Post UTME.
The graph above is correctly represented by
y = x2 - x - 2
y = x2 - 3x + 2
y = x2 - x - 1
y = x2 + x - 2
Correct answer is A
The graph crosses the x-axis at x = -1 and x = 2
Thus, x + 1 = 0 and x - 2 = 0
x\(^2\) - 2x + x - 2 = 0
x\(^2\) - x - 2 = 0
giving y = x\(^2\) - x - 2

From the venn diagram above, the complement of the set P\(\cap\)Q is given by
{a, b, d, e}
{b, d}
{a, e}
{c}
Correct answer is A

18%
28%
36%
50%
Correct answer is B
the 36th percentile i.e. 36% of the total frequency of 50.
\(\frac{36}{100}\) \(\times\) 50 = 18
= From the graph, 18 on the vertical axis corresponds to28 on the horizontal axis.
\(\therefore\) P\(_{36}\) = 28%
