The graph above is correctly represented by

A.

y = x2 - x - 2

B.

y = x2 - 3x + 2

C.

y = x2 - x - 1

D.

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

The cumulative frequency curve above shows the distribution of the scores of 50 students in an examination. Find the 36th percentile scores?

A.

18%

B.

28%

C.

36%

D.

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%
